CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application No. 61/737,799 filed Dec. 16, 2012 entitled Concept Characteristics Management System for the Enhancement of Requirements Engineering Documents which is hereby incorporated in by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention is a method and apparatus for a Vital Text Analytics System (VTAS) that improves the comprehensibility and fidelity of technical specifications, instructions, training manuals, engineering and other documents through a linguistic analysis of the lexical, syntactic, semantic, and pragmatic aspects of the text. More specifically the invention constitutes a computational Vital Text Analytics System that uses multiple layers of analysis based on a pedagogical curriculum referred to herein as the English 4 Engineers (E4E) framework. This framework organizes the interaction between the system and the user (document author), providing a framework for reporting analytical results to the user and for organizing the analysis process itself. The invention incorporates methods to identify these problematic features in the text and provides tools and resources that aid the author in understanding the nature of an identified problem in the text, determining how best to address the problem, and how to implement the needed change in such a way as to avoid introducing new difficulties by way of interactions with other parts of the document to enable the author(s) and other users to resolve these errors and improve the quality of the document. The invention provides a statistical ranking of the document quality according to a Vital Text Quality Index to allow authors to assess likely clarity and comprehensibility for those who must employ these documents for developing software and hardware solutions, or other activities that require technical language of great specificity. 
     BACKGROUND OF THE INVENTION 
     Requirements engineering is the process by which an organization formally identifies a need and defines the goals of a product or system it proposes to develop in response to that need. The process takes many forms and is applied with varying degrees of formality in organizations ranging from small software development shops to Fortune 500 corporations, as well as civilian and military government agencies. It is applied in defining physical products, software systems, complex transnational industrial systems and an unlimited variety of other projects. Successful requirements engineering accurately identifies the goals the client organization hopes to meet via the proposed system, determines and documents the functions the system will have to implement to satisfy those goals, identifies the interfaces and inputs the proposed system will depend upon, the intermediate and final products or outputs the system will generate, the form these inputs and outputs will take, the criteria the inputs and outputs must meet, and a wide range of other considerations that can bear on the success of the project. 
     Throughout these phases of product development, communications in document form are employed to explain operational and functional requirements, implementation strategies, risks, operating instructions, adherence to regulatory and industrial standards, and other engineering parameters. One or more individuals create this documentation based upon their areas of expertise and their knowledge of and experience with the development project. The documentation is developed for different levels of understanding of the project and for different audiences to interpret and use the information to develop, manufacture or use the products created. 
     A review of requirements engineering documentation created at the various levels may reveal the use of language and terminology consistent with the parlance and vernacular of closed groups that internally use these terms to describe the technology. These terms, whose unique meanings are only understood by the closed group, may be misunderstood by external readers who mistakenly assume their knowledge of the term&#39;s potential usages is complete. Commonly, the meaning of these terms may be misinterpreted or an insufficient explanation is provided within the documentation, because the closed groups have sufficient knowledge to understand the meaning and therefore do not expand, define or reiterate the importance of certain aspects of the requirements, because their meaning is accepted as common knowledge within the closed group. The misinterpretation and misunderstanding of critical requirements may have disastrous results where a user of the technology makes an incorrect decision based on their misinterpretation of instructions or operational parameters of the technology. Users of the technology may further misunderstand the unclear terms where their use is inconsistent, and possibly ambiguous to those outside of the closed group. 
     An excellent example of the importance of providing clear and broadly detailed requirements engineering documentation may have been provided by the 2009 crash of Air France Flight 447 in route from Rio de Janeiro to Paris. The precipitating cause of the accident was the icing of external sensors that caused the flight control computer to get inconsistent airspeed indications. That system had been designed to automatically return control of the aircraft to the crew in such an event. However, no one in the cockpit had ever manually flown an Airbus 330 (or a 330 simulator) at cruising speed and altitude, while facing anything much like the array of erroneous or contradictory instrument readings, warnings and alarms they then confronted. In this example, the design of the aircraft created implicit expectations for crew performance that were not recognized or adequately addressed in requirements for design of the training program for flight crews. 
     This example may be dramatic and tragic, but it is not isolated. It has been estimated that failures traceable to the requirements engineering process (e.g., vague, imprecise, incomplete, inconsistent, inaccurate or unrealistic requirements specifications) cause 40% of the defects that arise in projects. Poorly constructed requirements specifications fail to communicate fully and accurately the client&#39;s expectations to the engineers who are charged with realizing the client organization&#39;s desires. This failure can not only lead to disaster on occasion, but also to billions of dollars wasted on mitigation work needed to correct errors and deficiencies. 
     The most basic and general tool in the requirements engineering process is a human natural language (e.g., English, Japanese, Swahili). There are various efforts to insert artificial languages or graphical/symbolic systems into the process, but the fundamental goal of a requirements engineering exercise is to capture the needs and expectations of a group of human users, who typically also bring to the problem a fund of relevant expertise that the requirements engineering process must capture. The natural language (or languages) the user community shares serve as the medium in which they discuss, analyze, and amend the devices, systems and practices that will be replaced by the proposed new system. Not surprisingly then, the majority of requirements are stated in a natural language and they are formulated largely by way of extensive interactions in natural language between requirements engineers or business analysts and the user community. Sentences in a natural language then are both the raw material for the production of a requirements specification and the medium in which the requirements are stated. 
     Current commercially available requirements engineering tools are intended to help users develop higher quality requirements specifications, but they address this problem at the level of project management by: 
     A. helping engineers organize and review inputs to the requirements engineering process, 
     B. providing tools for collecting and evaluating drafts of individual requirements, 
     C. cataloging and tracking connections and interactions between different components, 
     D. tracking requirements that have and have not been addressed once implementation begins, 
     E. tracking the testing and evaluation of the implementation to ensure that the criteria associated with specific elements of the requirement are in fact met, 
     F. and once a new system is fully deployed assisting in managing revisions to the requirements and the process of implementing and assessing the revisions. 
     These tools of the prior art, however, fail to assist in determining whether the requirements statements themselves are employing language that is clear and unambiguous, whether connections between different requirements are clearly articulated, whether there is consistency in the use of critical terms, whether conflicts or contradictions have been addressed and resolved, or whether the requirements accurately reflect the users&#39; intentions and their expertise about the system to be developed. Some of the existing tools provide routine grammar- and spell-checking functions, but no existing product does anything to assess the quality, clarity and correctness of the requirements specification as a whole, as a textual language-driven document. Nor do they base their work upon research using valid linguistic and computational linguistic methods that identifies instances of language with high probability of miscommunication. 
     What is needed is a methodology that reduces defects caused by imprecise, vague, ambiguous, or incoherent linguistic communication in requirements specifications and other documents and a manner of identifying and storing unclear language, terminology and syntax to be used to amend and improve future documentation. Additionally, a method is needed that provides extensive interaction with all stakeholders of the system to increase their knowledge of terms (singly and in combination) and their implications and possible variety of meanings across the range of the application&#39;s use. 
     SUMMARY OF THE INVENTION 
     The method and apparatus of the present invention relates to a computational linguistic technology that can be brought to bear on core problems in requirements engineering and other documentation. These problems bear directly on the building of clear and coherent requirements specifications that may be used in the design, development, implementation and use of software and hardware technology products or other scientific or technical applications. The system of the present invention supports the discovery and identification of weaknesses in usage of a natural language used to describe a desired solution. Solutions, in the current implementation, include application software and hardware deliverables within an information technology (IT) organization or product deliverables within a corporate or other environment where a software and/or hardware solution is sold to others. In the following text the term solution applies equally to application (IT) and product (for sale) requirements documents that may be used to develop flow diagrams, schematics, inter-relationship models, design specifications, training manuals, and instructions to assist in the design, manufacture, implementation and/or coding of a software program, a mechanical apparatus, a computer controlled system, or other technology. 
     An analysis of these documents by the Vital Text Analytics System (VTAS) software application constitutes a viable method for reducing defects caused by imprecise or inaccurate communication in these requirements specifications. Specific issues occur in requirements specifications that lead to misunderstanding, reduced comprehension, an undermining of effectiveness, and a misrepresentation of relevant expertise. These issues may be identified and modifications to the text may be presented to correct or minimize potential misunderstandings by more clearly and comprehensively defining requirements. Other documents, such as annual reports, Food and Drug Administration (FDA) submission documents, other regulatory approval filings, medical evaluation documents and product development and design specifications may benefit from the Vital Text Analytics System (VTAS) where an analysis of terms within one or more documents will elucidate both broad and specific meanings of terms to assist in conveying concepts across both culturally and organizationally diverse users and consumers of varying expertise. In this vernacular, ‘Culture’ is defined as the culture of geographic nationality and origin, as well as the culture of occupational centricity where both may cause massive issues of miscommunication of language use in subject matter in any particular industrial area. Using the VTAS of the present invention that includes features such as the English 4 Engineers (E4E) framework, Natural Language Processing tools (NLP), Vital Text Concept Mapping (VTCM), and Vital Text Risk Assessment (VTRA) ambiguities and risk of miscomprehension within documents are identified and the frequency and relationships between these risks within a document are displayed to identify terms and phrases that may be problematic for comprehension. The VTAS further displays alternative explications of terms developed through both internal and external experts that allow an author or user to modify the use of terms within the document. Using these approaches, the VTAS supports the ability to quickly ascertain when a requirement may engage other concepts within the corporate repository, and therefore identify risks from misinterpretation of these terms. This capacity can also contribute to enhanced understanding and training for new employees or users. 
     Also importantly, the present invention provides a statistical ranking referred to herein as the Vital Text Quality Index (VTQI) that is aimed at assessing these risks using the frequency and severity of specific categories of ambiguities and related uncertainties, specifically lexical, syntactic, semantic, and categorical structural classes that are based on the identification of the relationship of terms through the contextual event and situational setting from the perspective of the reader using the E4E framework. Through this analysis, the potential risks identified are tagged and automatically assessed and marked within an extended form of the document called the Vital Text Computation Object (VTCO). Using the VTCO and risk assessment protocols, the VTQI is derived from an analyses of five distinct aspects of the document: (1) Syntactic Structure; (2) Transitional Probabilities; (3) Discourse and Pragmatic Structure Analysis; (4) Word Frequency, Collocation and Concordance Information; (5) Part-of-Speech (POS) Information; and (6) Associated Confidence Values. The VTQI score assists in identifying the inconsistencies and areas that may lead to the misinterpretation of similar concepts within a company or industrial area usage model and serves as a broad assessment of the clarity and intelligibility of a document or group of documents in a way that can be useful in project management, helping to determine for example, when a requirements document is mature enough to support the intended purpose or identifying the authors who most effectively achieve high quality documents. 
     In a first embodiment of the VTAS, implemented on a computer platform, the system may employ Vital Text Analytics System (VTAS) ontological analysis and decoding strategies to identify and support alternative language or linguistic structures increasing the effective comprehension of the resulting documents. The VTAS ontological analysis may further contribute to a “corporate or enterprise repository” created from the resources built within the context of the requirements analysis. An Ontological Library is used to collect within an Enterprise all the terms and concepts specific to the Enterprise. Through a process of explication development, the Ontological Library makes it possible for those employees and consumers using the requirements or other documents subjected to the VTAS analysis, to gain further clarification about terms and concepts employed in the Natural Language descriptions within the requirements text. Explications are a specific kind of definition that avoid common weaknesses of definitions produced by methods that define terms using words that require additional word meaning. Instead within the VTAS, explications are constructed from the use of the terms within one or more specific ontologies to encourage effective representation of information most critical for an employee, consumer, or user of the requirements document to understand. The data collected about the explications relates specifically to the corporate entity or technology field and the concepts that are accumulated through the VTAS linguistic analysis process and the meta-data gathered about those explications. The Vital Text Concept Library (VTCL) is fed by these explications of terms and concepts to further provide a condensed database of these terms and concepts which can be compared across Enterprise data from different operational entities and even completely different Enterprises where those Enterprises are willing to share their data for the benefit of gaining a broader conceptual understanding. 
     Realization of the corporate products and objectives are enhanced using the array of linguistic, cognitive science, and computational techniques, group and crowd sourcing methods, and other automated routines working in concert within the VTAS to evaluate the language within a requirements document or group of requirements documents for clarity. The automated support provided by the VTAS supplies the author, employee and consumer with a broad repository in the form of the Enterprise Ontological Library from which they may employ Group or Crowd sourcing methods to gain additional topological information regarding specific terms. The Ontological Library contains terms that may be chosen for further clarification. Through a manual review by a documents author or a VTAS data analyst directed by VTAS analysis findings and tools, specific terms and concepts that are found to be important to the comprehension of the document overall may be processed to create explications which provide a range of informative attributes and descriptive text. The explications are then connected to the document to support the reader in gaining additional insight into the term or concept by simply ‘mousing’ over the target word or words within the Vital Text Interface. 
     Group sourcing is restricted to those members within the technology community that have been selected by one or more authors or group source members who request the elicitation of information from these participants. Crowd sourcing is associated more broadly to users of the technology of the documents within the company. Having the terms available and the means to quickly and easily seek the group and crowd sourcing explicit expansion of the meaning of the terms provides a unique method for the consumer to gain, asynchronously, more information about the constructs within the document. The asynchronicity of the review is important, as research shows, because it allows respondents to manage their interactions more aligned with their schedules. As the reviewers respond to the requests for additional clarifying information additional Ontological understanding may evolve resulting in expansion of the Ontological Library. Further, expansion of the Ontological Library across additional operational groups and even Enterprises begins to form industrial and sub-industrial categories of ontological content providing even further understanding and topological mapping. Using these features of the VTAS, a circular evolution creates opportunities for advanced understanding of these concepts for authors and users of the documents. 
     Still further, the Ontological Library is employed to ‘shop’ terms using the group and crowd sourcing methods to gain explicit descriptions from universes of specialists to collect all understanding into one or more expansive repository within the Vital Text Concept Library (VTCL). Crowd sourcing and refinements of it may be implemented as well as other methodologies to aggregate the information obtained from multiple sources. The data provided may come from within a closed group associated with a specific technology. The data may be obtained from one or more inventors, engineers, experts, or specialists within a closed group through a compilation of explication templates, other requirements documents, technology specific publications, or other sources. 
     Using the VTAS linguistic analysis process, the system further provides enhanced, ongoing assessment, articulation and better integration of the concepts underlying the company&#39;s express needs found in the requirements. As requirements are evaluated, the VTAS offers tools that support the discovery of alternative and/or enhanced terms and phrasing that improve comprehension of the requirements document. 
     For example, in a first embodiment, one or more requirements engineering documents may be decoded, identifying commonly used terminology such as specific critical terms used within the Enterprise. Select terms may be displayed and color coded on the Concept Map. In one example, the VTAS using the Concept Map would identify where terms are used inconsistently or broken links in relationships, where an expression introduced at the beginning of the document implies a relationship that fails to be carried through to the end of the document. The VTAS further comprises processes of linguistic analyses that are organized around the principles of the English 4 Engineers (E4E) framework. The E4E framework provides a broad-spectrum tool for critiquing technical documents by considering the fundamental problem of comprehension from a reader&#39;s perspective and the skills of the author or authors in clearly presenting the information. This central task provides the organizing focus of the VTAS and affects the text analysis process from its earliest stages through to the presentation of the results of the analysis to the author of the document. Writers of technical documents often have relatively little training as writers, do not have a useful common vocabulary for discussing many of the issues that affect text quality, and in a significant number of instances may not be native speakers of the target language. Given these constraints, the VTAS provides value to a company&#39;s corpus by detecting problematic features in a text, identifying the problems they raise, offering possible solutions to those problems and effectively communicating this information to the author and the Enterprise users of the documents. The E4E framework is the integral part of the VTI that offers this opportunity for the author to investigate problematic text features at greater depth. 
     The core device by which texts convey rich and precise information to readers is the sentence, and the core difficulty in reporting problems to authors is that many writers have a relatively weak sense of what sentences are. Writers are often unclear on what constitutes a sentence, how sentences function, how the components of a sentence can be elaborated, how multiple sentences can be worked into a complex sentence structure, and how sentences, individually and collectively across a text, can reliably convey complex information. Even relatively proficient writers often have a weak explicit grasp of sentence structure and function. These limitations constitute a significant barrier to communication about problems in a text. 
     The E4E framework includes the Vital Text Sentence Model (VTSM), which represents sentences through three distinct layers comprising the nominal, predicative and situational aspects of language. E4E explains how each of these layers is elaborated to produce sentences of any possible level of complexity. Further, E4E includes the Vital Text Document Model (VTDM) which identifies the ways that sentences and sections of text relate to one another, the ways that references are maintained or undermined throughout a document, or a corpus of documents, and the ways that conceptual features extrinsic to a given sentence can affect its range of potential interpretations by a reader. The VTAS using the E4E framework provides a basis for adding an unlimited number of analytical and presentational modules that can help writers improve the probability that the intended meaning of the document will be communicated to the intended audience clearly and without significant error. These modules may run in parallel or in sequence, and may be turned on or off or given differential weightings for different kinds of documents, domains, organizations, industries or audiences. 
     The goal of the VTAS is not to repair or re-engineer submitted documents, since this task typically requires the special expertise, knowledge of project goals and constraints, and situational knowledge of the author. Rather the goal of the VTAS is to identify and report problematic features of a document and support the process of resolving those difficulties. The Vital Text Interface (VTI) that is displayed to the author and Enterprise users provides clear information that allows them to readily see the issue in the source text, understand the nature of the difficulty, and access whatever further support may be relevant to address the issue. 
     Through the Vital Text Analytics System (VTAS) analysis, each term and definition within the Vital Text Concept Library (VTCL) database is tagged with specific meta-data that includes source information, frequency and prioritization of usage of the term within the set of requirements documents. These attributes are used to group and isolate concepts within a consideration of two dimensions; where a first dimension is concepts employed at greater depth versus a second dimension of concepts employed at greater breadth in the document(s). Some terms and concepts are more at risk for misunderstanding than others. Further, the manner in which a term is distributed through a document affects how likely it is to produce a misunderstanding. The use of these data structures and the global comparison of terms provides for the identification of sets of company specific terms employed within the corporation&#39;s documents. This supports a corporate commitment to use a specified vocabulary and shared knowledge base consistently. 
     Using the ontological analysis system within the VTAS, terminology is selected for the corporate dictionary based on a variety of linguistic features and statistical analyses, including frequency, distribution, collocations, N-gram structure, parse trees, and many others. Often VTAS employs existing tools and applications to acquire source data that is later employed with specific algorithms unique to the VTAS processing methods. For example, Stanford CoreNLP provides a set of natural language processing tools that take text as input and marks up its structure in terms of word relations by pointing out names, locations and dates. Also, the Stanford CoreNLP is a natural language parser that can identify the grammatical structure of the text. It could, for instance, provide several possible “tree” structures of a sentence and calculate the probability of each of them being the actual (intended) structure, thus it can find structures that are potentially ambiguous. 
     The VTAS within the E4E framework applies and expands upon the syntactic and structural analysis to create relationships between the constituents of the requirements document so that all implied relationships between functional elements of the document are explicitly recognized. If an entity or its constituents are not linked in the requirements or in external documents then a link should be identified or alternatively be evaluated and if necessary the link be deleted. For example, the VTAS system may scan, identify and record the world of conceptual terms and phrases that exist within requirements engineering documents. It may also define specific entities as things related to both exclusive company terminology and to describe broadly accepted concepts within a specific technology field or industry. An ontological analysis within the VTAS identifies these suspected things and flags them for later inspection. The VTAS also incorporates meta-data using the E4E framework including their frequency, location and distribution within a document using a unique document identifier, and paragraph and line locators. Ontological reporting may further provide term variants or Z-Lemma information that may be used to identify morphological forms of a term within a document. Concordance algorithms within the VTAS further group and index the targeted terms in a relational manner within their context of usage based on the action and use in time of the terms. The Natural Language facets of a requirements document such as similar parts of speech, collocations, concordance values, conceptual relationships and other data are aggregated in a Vital Text Computation Object (VTCO) that is used in conjunction with the sentence constructs identified using the E4E framework to clarify actions and display risk elements to an author or data analyst that may require further clarification to support enhanced comprehension by the employee, the consumer and other users of the document. 
     The collected data and meta-data enhancements develop a characteristic and persona for each salient term of interest. A persona, in the word&#39;s everyday usage, is a social role or a character played by an actor. The word is derived from Latin, where it originally referred to a theatrical mask. The Latin word probably derived from the Etruscan word “phersu”, with the same meaning, and that from the Greek πρóσωπoν (prosōpon). Its meaning in the latter Roman period changed to indicate a “character” of a theatrical performance or court of law, when it became apparent that different individuals could assume the same role, and legal attributes such as rights, powers, and duties followed the role, and that the same individuals as actors could play different roles, each with its own legal attributes, sometimes even in the same court appearance. 
     The ‘persona’ or character of a term is documented by the ontological analysis and E4E framework constructions. This is done by establishing a term&#39;s usage relative to other terms within the document or within one or more documents, and by evaluating the term&#39;s occurrences, depth and breadth. To assist in describing a concept that has multiple personae across different parts of a company it may be considered in terms of concepts wearing different ‘masks’, depending on the context within the company. Examining the notion of personae from a different point of view with a practical example, consider a simple practice of using ‘red’, ‘yellow’ and ‘green’ to describe the status of a project. Someone could say: “Project 1 is red” to express its status—cancelled (for example). Or someone could say: “Project 2 is green”, as in “Project 2 is finished as planned”. This may conflict with other usage of these color terms as indicators to describe the stages of development of a project, as now someone could say “Project 3 is red”, where “red” means “at an early stage”. Or in a completely different way to identify the results of a particular medical test. Someone could say “The test is red” to outline the results of a test, but somebody else would think the meaning was “The test was cancelled”. In each example the RED indicator implies a “Stop” condition or a “DANGER” condition as is known from stoplights at intersections. But, in the example the REASON they are applied may be different for each case. In that interpretation RED may be some value was out of range in one situation and in another some process was not concluded correctly. The color terms therefore now have distinct conceptual roles when used in these different contexts, opening a door for confusion or misinterpretation. 
     Characterizing the personae (salient terms) associated with each concept through the analysis and indexing methods of the VTAS, the system may also assist authors of the requirements documents by recognizing and signaling when terminology is selected that is outside the customary usage stored within the corporate dictionary and management system. The VTAS exposes intersecting points of contextual contact and relationships with other concepts and elements that may be unknown to the author and may present these in real-time as the document is being written as optional choices in using the corporate nomenclature. By building this information, the VTAS assists in defining the focus and scope of the concept desired to be conveyed within one or more specific documents thereby providing information relative to all other things that exist within the document or within the corporate enterprise. The unique contribution of the VTAS is the ability to identify these masks and provide the many attributes and aspects of the personae of a particular term or concept and to clearly articulate the nature and context of usage in each instantiation using a variety of techniques and media. 
     The VTAS further provides the VTQI ranking that allows for comparison of a single requirements document with respect to classes of risk patterns or defects within a defect database. In many cases, the language that is weak or in one way or another not optimal will be found to strongly correlate with one or more classes of risk patterns that are discovered during industry standard verification and validation activities where requirements are realized and implemented. In examining the risk patterns classes a range or collection of defects that commonly occur may be identified. 
     As an example, in the validation of newly developed software applications, defects occur because software code is commonly a collection of repetitive operations across the domain of requirements. In validating the code, test cases are created to test each requirement and are linked to the requirement using a ‘traceability’ matrix provided by most Requirements Management Systems. Defects are identified where the implemented software code does not meet the requirements. These defects result in functional failures in the implementation of the software and because software code is a collection of repetitive operations, a defect caused by a single ambiguity in the requirements documents can result in multiple failures within the implementation. The VTAS analyzes these ambiguities against defects identified within the verification and validation reports and applies a correlation that quantifies the VTQI ranking. 
     The VTQI ranking further provides a baseline of the frequency of risk within a document based on battery of analyses that are aimed at assessing the frequency and severity of specific categories of ambiguities and related uncertainties, specifically lexical, syntactic, semantic, categorical ambiguities, and relational context of the nominal, the action and the situational setting. For example, using the analytical tools of the VTAS transitional probabilities and word frequency, collocation and concordance information is collected and evaluated to develop a statistical profile of individual terms. This analysis may then be used to select risk patterns that when compared to norms may contribute to highlight eccentric or critically distinctive usages that may lead to ambiguities. The inclusion of various statistical estimates associated with the probability of a given risk element in a given environment can help to identify where there may be challenges to comprehension. Through this analysis, these tagged sentence constructs pointing to potential risk elements are automatically assessed and marked in the VTCO and integrated into the document&#39;s VTQI score. This analysis and tagging may clearly identify problems in comprehension and thereby affect the document&#39;s overall VTQI score. As examples, if a risk pattern presents a confusing modifier linked with two separate terms, or a circular or obscure terminology is used to define one unique term or acronym by using another unique term or acronym; or a concept or representative term is not structurally well defined or a missing component reference is not found where it may be reasonably expected to occur, then each instance of these risk elements will be tagged in the VTCO and a statistical ranking will be given that will increase the overall VTQI score for the document. 
     The calculated value and ranking of requirements document using the Vital Text Quality Index (VTQI) is an important feature of the VTAS analysis tools of the present invention where it provides an index for valuing a document by the risks that may result from misunderstandings, failure or misuse of the software or technology product from poorly defined concepts. These misunderstandings may result in oversights or omissions in design, injury to the user, or users, or damage to the product. To evaluate and measure these risks the VTAS application software performs an analysis of many conditions that are known to increase a level of risk, for example language within the requirements that has previously been found to correlate to specific types of defects in software. This comprehensive analysis and ranking is a very important aspect of the present invention. 
     The VTAS application software further presents alternative representations of definitions and construction of terms by developing a topology of each of the specific terms. Topology may be defined as an object or family of objects having certain properties or attributes that are preserved as an object is transformed. These attributes may be within a range from generally known to more specific attributes associated with a specialized use of the object. For example consider the following term, “chair”, and how each of the five attributes may generally or more specifically define the object: 
     Chair 
     1) A structure for sitting 
     2) A back, four legs, a horizontal surface sitting atop the four legs, wheels for rolling about as one is seated, arm rests, cushions or padding to make sitting for extended periods more comfortable. 
     3) Use within a dental office domain may evoke, “ . . . able to be raised or lowered by one&#39;s foot . . . ”, or “ . . . able to be leaned back so the seated individual is almost horizontal . . . ”, or “ . . . accompanied by a number of attach points for accessories . . . ”. 
     4) Use within a dental office waiting room may evoke “ . . . not able to be raised or lowered by one&#39;s foot . . . ”, or “ . . . unable to be reclined . . . ”, etc. 
     5) Use within a dental office may evoke higher level provocations of medical furniture, dental furniture, special purpose furniture and lower level provocations of dental chair for dental surgery, for orthodontia, for general dentistry, for pediatric dental care. 
     Understanding the topology a specific term or phrase occupies within a domain or category of relevant terms or concepts is vital to communicating the meaning of the specific term or an underlying concept accurately. Through manual and automated analysis and a compilation of attributes that are comprehensively identified using the E4E framework, a suspect phrase may be properly targeted and categorized relative to its relationships and place within the communication hierarchy. Attributes may be collected through explication templates with experts within the company or within the industry. Attributes may also be collected from novices or peripheral users of the technology with less information about the technology and terminology. Other resources such as industry journals, patents, corporate documentation, dictionaries, etc. may also be used to broaden categorization of the targeted terminology. 
     The compilation of the explications and contextual information results in the identification of diverse interpretations where for example a first interpretation may present a lengthy explication from an expert working within a company where the terms used are narrow and specific within the group of experts, however open to multiple interpretations (roles) when a novice interprets the definition provided within a much broader scope. The separation of an expert category topology that contains narrower mid-line mapping or scope always exists and must be targeted to provide additional context and more specific detail for a novice. The E4E framework, Concept Map, VTQI ranking and other supporting modules within the VTAS assist in mapping out the relationships, usage and context of terms within both the expert and novice usage ranges by identifying gaps and disconnections with these terminology relationships that may result in risk elements. 
     Consequently, the broader relational mapping presents the opportunity for a normalization of usage to create palatable conceptual terms and descriptions that take into account the audience requiring the information. The VTAS performs the task of detecting the conceptual usage of a term or concept within a document and presents optional explications in order to re-align the novice user or consumer with the expert&#39;s level of communication. This may be accomplished through a variety of methods such as by presenting iterative representations of a term based on the optional explications that guide the novice to effectively arrive at the level upon which the expert is communicating. The identification of this requirement for the proper level of understanding and evaluation of the contextual attributes using the Vital Text Computation Object (VTCO) and other tools employed by the VTAS is a critically important feature of the VTAS in adapting requirements engineering terminology for the specific contextual users of the information. 
     In computationally deriving the Vital Text Concept Library (VTCL), other factors related to the contextual attributes of the knowledge, experience and familiarity of the employees, consumers and other users, and the reported information may be used to construct a hierarchical representation of the attributes that may rank the clarity of a series of explications that range from most general to most specific. For example, attributes most immediately reported by informants are given a higher ranking with respect to the term or target phrase than those provided in later recollections. A high ranking may also be assigned to attributes that may be reported by domain specific respondents defining terms which may be more relevant to the specific use of the target phrase. A clear and concise explication developed by a person having special skill or knowledge derived from training or experience as it pertains to the target phrase may be given moderate ranking. While attributes that may be relevant in a general use of the salient phrase but are irrelevant in the specific usage of the salient phrase may be given a low ranking. Compiled attributes may be presented in a hierarchical structure from more specific to more general terms associated with the salient phrase to assist a data analyst in validating the risk assessment of the salient phrase and associated concepts. 
     A reduction in significant errors in specifying the concepts which define a company&#39;s needs will also be achieved where the system may provide an option to switch among the original or one or more sets of alternative terminology and phrasing to define a particular concept. Using the Concept Library (VTCL), information may be provided on known risks in terminology usage to adopt clearer and more comprehensive definitions and usage much earlier on in a development project. The alternative language and optional definitions through explications may be passively accepted or actively selected from suggested enhancements based on the original language. Enhancements displayed using the Vital Text Interface are accompanied by supporting linguistic and cognitive reasons developed from the term attributes and explications within the Vital Text Computation Object (VTCO) and Vital Text Concept Library (VTCL). 
     Greater clarity and efficiency in writing and annotating test objectives, requirements and results will reduce time and iterative corrections to, for example, software code, mechanical tolerances, or the interaction between components within an electrical or mechanical system. Particularly, an analysis of the software requirements by the VTAS may provide enhanced traceability of source code terms and language elements and related product documentation, facilitating the maintenance, modification and adaptation of the software product or its reusable components used in the design and implementation of the requirements. Improvements will also be seen in the resulting architecture and system component design documents drafted by solution architects and software engineers, and the source code engineered to deliver the computerized functionality desired by the stakeholders within the company. The E4E framework may further provide instructional methods that will result in a substantial enhancement of the methods most often employed today in the requirements engineering and software development process and will help in eradicating defects resulting from errors currently inherent due to the lack of methods and understanding of linguistic challenges which directly enhance comprehension of the natural language employed within the requirements specifications by authors, employees, consumers and other users of the requirements language and/or any written text articulating concepts or information vital to an ancillary operation or activity where miscommunication is critical to avoid. 
     One object of the present invention is to implement a software development tool set on a computer platform that enhances the comprehension of requirements or other documents by more clearly presenting the most relevant concepts.

     Another object of the present invention is the reduction of risk associated with communication failures in requirements and other documents for software and hardware solutions by using substantially more effectively constructed terminology supplied by the Vital Text Analytics System of the present invention. 
     Another object of the present invention is a determination of targeted terms using the E4E framework and Vital Text Computation Object (VTCO) that comprehensively presents, compares and evaluates all of the contextual attributes applied to the requirements document using the VTAS analysis software. 
     Another object of the present invention is the development of a Concept Map that visually presents the relationships between salient terms that may be identified as nouns, verbs, adjectives, possessives and other parts of speech. 
     Another object of the present invention is to present iterative representations that are adapted to the knowledge, experience and familiarity of the readers of the requirements documentation. 
     Another object of the present invention is the creation of a collection of all terms employed within the processed documents to create one or more of a company, corporate or public enterprise ontology. 
     Another object of the present invention is the grouping of similar representations in a category topology to align definitions of terms by expert users with interpretation of terms by novice users. 
     A further object is the development of more accurate and complete requirements for software and hardware design specifications. 
     A further object is greater efficiency in writing, annotating and testing of software code based on the improved design specifications. 
     A still further object of the present invention is a reduction in defects resulting from identified risk elements currently inherent in the lack of methods which directly enhance the natural language employed within the requirements documents and specifications. 
     Still further objects of the present invention is an improvement in readability and understanding of documents in order to reduce rework that must be performed as a consequence of fixing unknown defects.

     DETAILED DESCRIPTION OF THE INVENTION 
     In the method and apparatus, a concept characteristic management Vital Text Analytics System (VTAS) software application implemented on a computer platform using an internet or intranet based application software is described. The Vital Text Analytics System (VTAS) processing software  20  comprises analytical tools that apply constructs derived from the E4E framework  50  to analyze documents stored within a data collection module  10  based on terminology and expressions stored within repositories that may include a Linguistic Repository  60 , an Enterprise Repository  70  and an Industry Repository  80  as shown in  FIG. 1 . 
     A user of the VTAS  20  may be the author or authors of the document within a company requiring an analysis of one or more of their corpus documents. As shown in  FIG. 2 , the original document  22  is submitted from the user in a variety of formats (e.g. .doc, .docx, .pdf, etc.) and uploaded to a secure server. The original document  22  is converted into a standard plain text format and words, phrases and sentences are marked up using a number of Natural Language Processing NLP algorithms  24  integrated within the VTAS. These lemmatize the lexical material, insert Part of Speech (POS) tags, do Named Entity Recognition (NER), construct one or more syntactic analyses of each sentence, and perform various other preliminary analyses. The results of all of these analyses are encoded in an XML format  26  in a new document. Lemmatizing lexical material means to determine what lemma each word form is associated with. Thus, walk, walks, walked, and walking are all taken to be variant realizations of the same lemma, walk, and are annotated in the XML format  26 . 
     In a further processing step, the Vital Text Sentence Model (VTSM)  28  further guides mark up the XML formatted file  26  to tag structural classes  43  as defined within the E4E framework  50 . For example, arguments of the matrix linker  47  in each sentence are distinguished from more deeply embedded pointers  45 , and indexes of the complexity of the matrix arguments are constructed. After the sentence by sentence analyses is run and the XML file  26  is appropriately tagged according to the VTSM process  28 , the collection of all sentences (i.e., the text) is run through another process using the Vital Text Document Model (VTDM)  30  to extend the analysis through groups of related sentences or sections to develop one or more ontologies or other higher level analyses of the document. As in the previous step, in the Vital Text Document Model (VTDM) processing step  30  adds a set of text-level tags to the XML document  26  to facilitate the application of the E4E framework to the document as a whole. 
     Here of particular note is the development of secondary ontologies derived via the VTDM  30  that assist in estimating what aspects of a primary ontology of the document are likely to be shared by readers approaching from various backgrounds and perspectives. These alternate ontologies generally draw upon corpora representing typical documents in relevant domains distinct from that of the primary document  22 . Further processing may be performed through an analysis using one or more collections of documents found within the Enterprise Repository  70 , or the Industry Repository  80 , each of these drawing upon a Corpus Model (CM)  32  analysis. The Corpus Model (CM) may assist in estimating typical usage of salient terms in various definable domains relevant to the primary document  22  or to communities of prospective readers that may need to read the primary document  22 . The CM  32  processing of relevant documents may identify elements that are used idiosyncratically relative to current practice in an industry or some relevant technical domain. 
     The results of the NLP, VTSM, VTDM and/or the CM processing analyses are incorporated in the Vital Text Computation Object (VTCO)  34  that is in a heavily annotated XML format. The VTCO  34  is stored in a VTAS process server  19 . The VTCO  34  is in effect a multi-layered document with tagging that includes each word-level element of the original source document  22 , along with tagging indicating its relation to each of the distinct layers derived from the E4E framework  50 . Using the VTCO  34  each word-level element (as well as larger structures) can be considered in relation to a single layer of the model or be simultaneously examined by a data analyst  48  to determine the element&#39;s impact on the multiple layers and structures within the document. 
     The Vital Text Computational Object (VTCO)  34 , which is an extensively tagged version of the original document  22  further becomes the basis for applying the Risk Detector (RD)  38  and Risk Assessor (RA)  39  processes to the document  22 . The Risk Detectors (RD)  38  apply Risk Patterns  63  whose Risk Elements  65  have been shown to be capable of introducing one or another kind of risk of misinterpretation that presents an ambiguity or interpretive uncertainty into the document  22 . The identified Risk Elements  65  with all of the markups inserted by the Risk Detectors  38  are integrated into an Analyst Target List (ATL)  42  that includes all of the original markup of the VTCO  34 . The ATL  42  is the most comprehensive representation of possible problematic features of the document  22 . 
     The Risk Assessors (RA)  39  are processes instantiating various machine learning algorithms. These processors take advantage of a) studies of human performance with the Risk Elements  65  in question, b) a variety of other relevant measures of the context in which each Risk Element  65  introduces, and c) specific details of the way each particular Risk Element  65  is lexically or structurally realized. Each Risk Assessor (RA)  39  assigns a rating to each Risk Element  65  indicating the estimated probability that the specific instance will induce significant uncertainty for readers. In some instances, further information indicating which particular possible interpretations or analyses are most likely can also be reported by the RA  39 . The class of Risk Elements  65  marked by each RD  38  will have at least one RA  39  that assesses the degree of risk associated with each tagged instance of that Risk Pattern type. However, RAs operate on the VTCO  34  and can be defined to take advantage of any of the information found there, including tagging that is derived from multiple Risk Patterns  63  developed by various Risk Detectors (RD)  38 . Risk Assessors (RA)  39  are also able to examine Risk Elements  65  in relation to multiple relevant document ontologies, representing both the author&#39;s intent and the various baseline ontologies that various classes of reader may bring to the text. 
     The results of the Risk Assessor  39  processes consist of a highly filtered and ranked Client Target List (CTL)  44  that lists the Risk Elements  65  in the primary document  22  that are considered highly likely to induce misinterpretation or other problems. The CTL  44  is designed primarily to contribute to an iterative process of document review by an author, employee, or another user of the document  22  by highlighting the most critical Risk Elements  65  and issues identified by the Risk Assessors  39 . The Client Target List (CTL)  44  is incorporated within and displayed through the Vital Text Interface (VTI)  40  that allows an author to review the identified Risk Elements  65  with the original text of the document  22 . 
     Some embodiments of the present invention will be described in terms that would ordinarily be implemented as software programs. Those skilled in the art will readily recognize that the equivalent of such software may also be constructed in computer, electrical and communications hardware. Because data manipulation algorithms and systems are well known, the present description emphasizes algorithms and features forming part of, or cooperating more directly with the method and hardware of the presently disclosed invention. General features of databases, digital communications devices, email and computerized systems are likewise well known, and the present description is generally limited to those aspects directly related to the method and related hardware of the invention. Other aspects of such algorithms and apparatus, and hardware and/or software for producing and otherwise processing the data involved therewith, not specifically shown or described herein may be selected from such systems, algorithms, components, and elements known in the art. 
     The present invention can be implemented in computer hardware and computerized equipment. For example, the method can be performed using a system including one or more digital communications devices and/or one or more personal computer systems. Referring to  FIG. 3 , there is illustrated a computer system  3  for deploying the present invention. Although the computer system  3  is shown for the purpose of illustrating a preferred embodiment, the present invention is not limited to the computer system  3  shown, but may be used with any electronic processing system such as found in digital communications devices, cellular phones and other mobile devices, home computers, tablet computers, or any other system for the processing of digital data. The computer system  3  includes a server computer  4  having a microprocessor-based unit  5  (also referred to herein as a processor) for receiving and processing software programs and for performing other processing functions. An output device  7  such as a visual display is electrically connected to the microprocessor-based unit  5  for displaying user-related information associated with the software, e.g., by means of a graphical user interface. A keyboard  8  is also connected to the microprocessor-based unit  5  for permitting a user to input information to a software program. As an alternative to using the keyboard  8  for input, a mouse  6  may be used for moving a selector on the display  7  or alternatively a touch screen input device may be provided for selecting an item and operation of the software application. 
     The output device  7  provides visually to the user transactional data that has been subject to transformations. The output device  7  can be a monitor, a tablet computer, or other visual computer screen or graphical user interface (GUI) a printer or other output device that provides a visual or other representation of a final output from the microprocessor-based unit  5 . The output device  7  can also be an output device that provides the transactional data as a digital file. 
     The microprocessor-based unit  5  provides means for processing the transactional data to produce readily discernible, informational and organized images and data on the intended output device or media. The present invention can be used with a variety of output devices that can include, but are not limited to, a digital photographic printer and soft copy display. Those skilled in the art will recognize that the present invention is not limited to just these mentioned data processing functions. 
     The server computer  4  shown in  FIG. 3  can store a computer program product having a program stored in the computer readable storage medium  11 , which may include, for example: magnetic storage media such as a magnetic disk or magnetic tape; optical storage media such as an optical disc, optical tape, or machine readable bar code; solid state electronic storage devices such as random access memory (RAM), read only memory (ROM) or flash memory data storage devices. The associated computer program may be stored locally and or remotely on a virtual machine (VM) or data center using any other physical device or medium employed to store a computer program indicated by offline memory device. 
     It should also be noted that the present invention can be implemented in a combination of software and/or hardware and is not limited to devices which are physically connected and/or located within the same physical location. One or more of the devices illustrated in  FIG. 3  can be located remotely and can be connected via a network connection  13 . One or more of the devices can be connected wirelessly, such as by a radio-frequency link, either directly or via a network connection  13 . It is to be appreciated that such devices can be mobile devices (e.g., camera, PDA, MP3 players, iPod, iPad, tablet computer, smart phone, or cell phone that can be used as a processing unit, a display unit, or a unit to give processing instructions), and as a service offered via the World Wide Web  14 . 
     In each context, the invention may stand alone or may be a component of a larger system solution. Furthermore, human interfaces, e.g., the input, the digital processing, the display to a user (if needed), the input of user requests or processing instructions (if needed), the output, can each be on the same or different devices and physical locations, and communication between the devices and locations can be via public or private network connections, or media based communication. Where consistent with the foregoing disclosure of the present invention, the method of the invention can be fully automatic, may have user input (be fully or partially manual), may have user or operator review to accept/reject the result, or may be assisted by data or metadata (data or metadata that may be user supplied, supplied by another computer program or database from a different application or determined by an algorithm). Moreover, the algorithm(s) may interface with a variety of workflow user interface schemes. 
     In the following description, some features are described as “software” or “software programs”. Those skilled in the art will recognize that the equivalent of such software can also be readily constructed in hardware. Because data manipulation algorithms and systems are well known, the present description emphasizes algorithms and features forming part of, or cooperating more directly with the method and hardware of the presently disclosed invention. General features of databases, digital communications devices, email and computerized systems are likewise well known, and the present description is generally limited to those aspects directly related to the method and related to the implementation of the software on computer system, electronic and communication system hardware of the invention. Implementation of the present invention may be in conjunction with one or more database management systems (DBMS) such as Oracle, IBM DB2, Microsoft SQL Server, PostageSQL, MySQL, or others using widely supported database languages such as SQL to define and manipulate data and perform data queries. Other aspects of such algorithms and apparatus, and hardware and/or software for producing and otherwise processing the data involved therewith, not specifically shown or described herein may be selected from any such systems, algorithms, components, and elements known in the art. The present invention may further be implemented on a secure web server  9  or secure remote data center using SSL, SHTTP or other security protocols for encryption and decryption of transmitted data. Data replication and redundancy is performed automatically and all servers are secured in optimal conditions. Further security is provided where each linguistic analysis project is setup using a unique domain name that is active solely during the period of analysis, and may be immediately deactivated upon project completion. At project completion, the entire database with all data may be ported to a storage unit and provided to the company as a secure record of all processing steps, communications and transactional data of the VTAS project. Secure management of the company&#39;s property protects it from unauthorized access while obtaining the widest possible input regarding development of alternative language. 
     The Vital Text Analytics system (VTAS)  20  of the present invention enhances the comprehension of requirements, specifications and other documents and may be implemented through application software  17  and as a web-native software application delivery model or SaaS (Software as a Service) to be hosted and operated as an on demand computing service such as a cloud or shared resource database through a web browser. The software includes policies and protocols in cloud description language (CDL) and domain specific languages (DSL) for this implementation to manage and monitor secure access and system usage to one or more data centers to provide multiple virtual servers with each server serving one or more instantiations of the VTAS operations. The implementation may further provide synchronization of local and remote desktop clients using virtual machine VM check in and check out operations to maintain access to the most recently updated local or remote copies that reflect user changes to accessed data files. 
     A secure login with password is provided to access the VTAS  20  locally or remotely with one or more users given privileges to modify, monitor and/or review the language enhancement process. Users of the VTAS  20 , as shown in  FIG. 4  may be business analysts, system analysts or requirements engineers  46  that interview stakeholders to author and develop requirements and engineering specifications and documents, data analysts  48  that are internal or external to a company and are performing the review and analysis of the company specified requirements documents using the VTAS  20 , users  46  who are working with a company to develop, manufacture, train, operate or support a software or hardware technology product described within the requirements documents. Each user  46  is granted appropriate access to the secure project specific domain  9  through an administrator using administrative tools  21  to control the levels of access so as to prevent or limit access to the VTAS  20  through pre-defined privileges based on responsibility and expertise. 
     In a first embodiment, as shown in  FIG. 4 , one or more formatted or unformatted requirements document(s)  22  are downloaded to the VTAS  20  through an internet  14  or intranet network connection  13 . The input documents  22  comprise for example statements exemplifying concepts, data, instructional information, regulatory information, requirements database elements and/or other requirements associated with a company&#39;s desired design or process outcomes. A company may be a business entity, a government entity, an individual or a group of individuals that are stakeholders in the desired design outcome. Administrators and data analysts  48  may be internal and/or external to the company. The documents  22  are then stored in, for example, a Vital Text Repository  19  for processing. A secure web domain  9  is modeled and configured based on information from the requirement documents  22  and a unique project name is given to the domain. Each document  22  is given a unique file name for processing and identification that includes source information, the project name, the date, a time stamp and a revision number. 
     Using the VTAS  20 , the document(s)  22  are first modified by spell, grammar and other standard quality tools  23  to correct spelling, grammar, and other basic faults identified by common automated methods as shown in  FIG. 5 . Terms or concepts and the remaining text is tagged for analysis and stored in the Vital Text Repository  19  for further processing. A text parser  25  performs preliminary low-level parsing algorithms to recognize and tag various structural features of documents that are related to document organization (e.g., headings, paragraph numbers, graphical marks such as horizontal rules). Using the VTAS  20 , the document(s)  22  are converted to a machine readable format  27 , such as XML, to encode and serialize the data to undergo Natural Language Processing (NLP)  24  using one or more linguistic analysis tools. 
     Automated processing in this stage employs a collection of linguistic and cognitively oriented tools to develop the Vital Text Computation Object (VTCO)  34 . For example, through the Vital Text Sentence Model (VTSM)  28  one or more available linguistics data services may be used to guide analysis and tagging through a wide range of analyses and tagging tools for identifying the Parts of Speech (POS) and for annotating the morphemes, words and larger structures of the text with further document-specific and domain-specific information that serves as critical input to later stages of the VTAS  20  process. A collocation analysis that finds word pairs or phrases that occur unusually often, as determined statistically, are also identified and tagged or logged. Terms that are unique to the sponsoring corporate or organizational entity may also be identified and tagged in the XML formatted file. Through a lemmatization process, variant word forms that represent different manifestations of a common core of semantic or functional content are also tagged. For example, the word ‘walk’ has variant forms such as ‘walks’, ‘walked’, and ‘walking’, all of which invoke the same core semantic content. An N-gram analysis may also be performed to identify a contiguous sequence of n items from a given sequence of text or speech. The items can be phonemes, syllables, letters, or words according to the VTSM process. One of the most important analyses at this stage addresses the syntactic structure of the text. Drawing upon a variety of parsing algorithms, one or more syntactic tree structures are constructed for each sentence (or candidate sentence) and the probable adequacy of each structure is estimated. One or more algorithms for Named Entity Recognition are also applied to tag expressions that may have special or unique value in the text. Further lexical and syntactic analyses are applied to detect and tag words and structures that are potentially involved in anaphoric relations across sentences. There are also algorithms that seek out and tag points within sentences where different candidate ontologies for the text as a whole may be particularly consequential for syntactic, semantic or pragmatic analysis of the individual sentence. 
     As shown in  FIG. 6 , further analysis is performed by applying the VTSM  28  and VTDM  30  derived from the E4E framework  50 . The VTSM  28  distinguishes three semantic/pragmatic functions pointers  45 , linkers  47 , situators  49  that must be addressed by even the simplest sentence. The art of sentence construction that the VTAS is designed to foster rests on how well each of these three functions is executed within a sentenced, given its context of occurrence. The classes of sentential substructures that invoke these functions (Structural Classes  43 ) constitute well-recognized distinct structural domains within sentences. The distinctiveness of the VTSM  28  consists not in discriminating the substructures associated with each of the three structural classes  43 , but with the functional perspective taken toward the work that these elements do in the sentence. The non-standard terms applied to these three structural classes  43  are meant to highlight the functional role of the structures. This moves the focus away from the notion of a sentence as a pattern or layout of materials and toward a conception of the sentence as a tool that engages three quite specific (and quite remarkable) cognitive functions in the reader. 
     The E4E framework  50  is not a ‘traditional pedagogical grammar’ of English. Though the model in full does align relatively tightly at some points with most generative models of English syntax, it is not derived from any formal generative grammar of English. Rather, the E4E framework  50  approaches English from a consistently practical and intuitive perspective. It considers sentences in terms of putative cognitive functions that are readily apparent to linguistically naive speakers, but whose relation to sentence structures and other cognitive resources of humans is far from completely clear. In speaking of the functions as ‘pointing’, ‘linking’, and ‘situating’, each of these being associated with a structural class  43  referred to herein as pointers  45 , linkers  47  and situators  49 , respectively. 
     The VTAS  20  performs an analysis of each sentence by identifying the structural classes  43  and their implementation and relationships within a sentence  51 . A sentence  51  must effectively indicate one to three entities (broadly conceived) that are accessible to the reader and should do so in a way that reflects the status of each entity relative to the current domain of the discourse as the reader sees it. This is done with pointers  45 , structures that have nominals as their lexical core, generally known as Noun Phrases or Determiner Phrases. In the sentence, ‘Transistors generate heat’ the word ‘transistor’ is a generic reference that covers more or less everything that can be denoted by the nominal term ‘transistor’. The sentence, ‘A transistor is generating excess heat’ indicates to the reader by use of the expression ‘a transistor’ that the entity at issue is a transistor, but not a particular one that is currently in focus in the discourse. The sentence ‘The transistor generates excess heat’ indicates by use of the expression ‘the transistor’ that a specific transistor is in question and that that transistor should already be identifiable for the reader on the basis of prior discourse context. Most especially, pointers  45  are not seen here as structures with direct relations to entities in the world, but only as tools for indicating entities within, or to be constructed in, the conceptual space of the reader at a given point in a sentence  51  in a text. The sentence  51  must indicate a ‘scenario’ that is specified by the verbal core (typically termed a Verb Phrase) of the sentence  51 , a linker  47 . The linker  47  intuitively and most typically indicates an event involving multiple entities, as in the sentence  51 , ‘The transformer damaged the circuit.’ a relationship, as in ‘The circuit resembled an amplifier.’, or an event involving only one entity, as in ‘The transistor failed.’ The VTAS performs an analysis to identify each of the linkers  47  as logical forms suggested by these formulae: damage (transformer, circuit), resemble (circuit, amplifier), fail (transistor), i.e., as instances of a damage linker, a resemble linker, and a fail linker. Consistent with the functional approach to the sentence that characterizes the E4E framework  50 , these formulae are seen as function-argument structures. That is, the linker  47  is seen as invoking a function that maps the arguments (invoked by the pointers  45 ) into a scenario of a kind determined by the linker  47  itself. Where there are multiple pointers  45  in a sentence  51 , the morphosyntax of the sentence  51  indicates which pointer  45  is assigned to each role indicated by the linker  47 . That is, the linker and its relation to its arguments plays a similar role to the other two functions (those associated with pointers  45  and situators  49 ) in that it indicates how the relevant entities are involved in the scenario indicated by the linker  47 . It allows the writer and reader to distinguish ‘The robot damaged the hoist’ and ‘The hoist damaged the robot.’ 
     The sentence  51  must also situate the scenario in time, as the temporal context is conceived by the reader. The situator  49  or situators of a sentence  51  (e.g., tense; in technical terms, the sometimes complex material commonly linked with a Tense Phrase or Complementizer Phrase) transforms the abstract scenario indicated by the pointers  45  and linkers  47  into a claim about some specific event or situation in time (or out of time, depending on specifics of the structure). Both the pointers  45  and situators  49  of the sentence operate within the discourse domain defined by the reader&#39;s current conception of the ‘world’ invoked by the text. 
     Each sentence  51  and section  53  of the document  22  is analyzed using the VTAS  20  to identify and tag all relevant material in each sentence in relation to the structural classes  43  as pointers  45 , linkers  47  or situators  49 . Any structure punctuated as a sentence  51  that fails to incorporate each of the structural classes  43  is identified and tagged for special handling using the VTSM  28  within the VTCO  34 . Various interfaces to the VTCO  34  are able, through highlighting and mouse over effects, to present the identified classes  43  for each of the well-formed, complete sentences as an organized set of data that supports a progression from data to information and to knowledge on the part of analysts  48  and authors using the VTAS  20 . The VTAS  20  integrates metadata at every level of analysis from the sentence  51 , document  22 , and corpus  32  levels as shown in  FIG. 7  to structurally tag  55 , and contextually tag  57  document content using the E4E framework  50 . Analysis and tagging generally proceeds left to right in  FIG. 7  such that the opportunities for contextual tagging  57  and analysis, and for risk assessment  61  are enhanced by the processes to the left of each of these phases of the VTAS process. The VTAS  20  develops and uses the rich body of metadata it incorporates into the surface form of the text to create a far more informative data structure that greatly facilitates detection and analysis of problems affecting the comprehensibility of the text from the perspective of the reader. 
     Much sentence complexity is treated in the VTAS  20  using the E4E framework  50  as deriving from two very general processes, subordination and coordination. This is primarily a pedagogical stratagem to facilitate communication with users, though it does also affect some aspects of tagging and other relevant processes. The emphasis is on showing that much of sentence complexity can be seen as deriving from these two very general and intelligible combinatory processes, each being manifest in many forms. Subordination is presented as a very general process of building structures by combining pairs of structural elements of different kinds in such a way that the newly formed structure is able to invoke a function different than that of either constituent. For example, a Prepositional Phrase (e.g., ‘beside the altimeter’) is presented as invoking modification a function that neither ‘beside’ nor ‘the altimeter’ can invoke, but where the preposition ‘beside’ is the privileged constituent that determines the functional role of the combined structure. Coordination is presented as an alternative mode of sentence elaboration which is characterized by leaving the functional role of the coordinated structures untouched and giving them essentially equal roles in the combined structure. For example, in the sentence  51 , ‘The follower arm must respond rapidly and reliably.’; the adverbs ‘rapidly’ and ‘reliably’ play identical functional roles relative to the verb linker  47  ‘respond’, and neither is in any sense privileged relative to the other. A pedagogical advantage of the E4E sentence model (given its focus on the three core functions implemented by the three structural classes  43 ) is that it readily extends to some kinds of coordination that can be quite puzzling when considered in purely structural terms. For example, in the sentence, ‘The helical gear was a critical component and essential to the control of pitch’ the coordinated structures are ‘a critical component’ and ‘essential to the control of pitch’, which are of different syntactic forms, the first being a Noun Phrase  45  and the second an Adjective Phrase. Commonplace descriptions of coordination suggest that such a coordinate structure is impossible. Nevertheless, the two disparate structure types that are coordinated in this instance work because each makes the same kind of functional contribution to the sentence within which the coordinate structure sits. 
     The E4E framework  50 , again largely for pedagogical reasons, approaches lexical and morphological issues in such a way as to stress the simplicity and consistency of English processes to the extent possible. With that goal in mind, lexical and morphological issues are treated as providing a surface layer to a sentence  51  that often adds a very specific flavor and texture reflecting the particular words and forms chosen, but that also is very strongly shaped by and integral with relatively simple and consistent core principles reflected in the VTSM  28  and VTDM  30 . The emphasis is on showing how the most regular and consistent forms in the language allow for the realization of the three core sentence functions related to the three structural classes  43  of the E4E framework  50  sentence model. The irregularity characteristic of many of the most common words in the lexicon is, wherever possible, positioned as a distortion of regular processes and patterns in the language. The focus is on distinguishing the systematic core of the language from the many relatively superficial eccentricities that arise, especially in relation to the lexicon. The ultimate aim is to make it easier to explain to an author what the issues are with a text and how those issues can be most effectively addressed. 
     The VTAS  20 , consistent with the E4E framework  50 , and like many other approaches to discourse, is designed to approach a text  22  as a sequence of sentences that ideally will incrementally guide the reader from some initial understanding and perspective on the topic at hand to an understanding and perspective the author has in mind. The reader&#39;s process of incrementally interpreting text is complex in that it involves questions of the (possibly disparate) goals of the author and reader, the problem of determining what set of referents are in view (for the reader) sentence by sentence over the text, the role of background knowledge, assumptions that may or may not be shared by author and reader, and a variety of other matters. All of these issues can vary across relevant subgroups of a document&#39;s intended readers. Since the sequence of sentences in technical writing is typically composed entirely of assertions, some complexities are avoided (especially with respect to situators  49 ). But those technical documents that are written on the assumption that some or all of their subparts can be read in isolation, without regard to any ordering of those subparts relative to each other, raise other sorts of difficulties that distinguish them from typical linear texts. Specifically, while the VTSM  28  applies readily to single sentences or within small blocks of text, other issues arise as to how the reader&#39;s background knowledge and current viewpoint are to be assessed. The E4E framework  50  provides a coherent and consistent framework for addressing all of these matters with authors. 
     In processing a document through a sentence by sentence analysis, the VTAS  20  software will tag each word with an appropriate part of speech (POS) identifier, introduce lemma information for each word, estimate one or more possible syntactic parses for the sentence, and conduct a variety of other preliminary analyses, that will tag each word with an appropriate part of speech with the results of which will be encoded in tagging added to the VTCO  34 . Importantly, the VTAS  20  process focuses on three major cognitive functions (defined within the E4E framework  50 ) that are invoked by sentences. This central focus of the sentence analysis process is the identification and tagging of those structural features of the sentence that bear on those three functions. All such tags are added to the VTCO  34 . 
     Using the VTSM  28  process, the VTAS software will perform an initial scan to identify and tag the structural manifestations of pointers  45  (generally, Noun/Determiner Phrases) within a sentence is performed using VTSM  28  processing features of the VTAS  20 . In the example sentence, ‘The admin widget will manage new users and requirements.’, the VTAS  20  software identifies ‘the admin widget’ and ‘new users and requirements’ and tags these as the primary pointers in the sentence. The VTAS  20  then using a number of components, modules and resources steps through a series of process steps to; a) assess the definiteness of these structures, b) distinguish ‘widget’ as the head of the first pointer, c) recognize the coordinate structure of the second pointer, d) estimate whether the adjective ‘new’ is intended to modify both ‘users’ and ‘requirements’, or only the first of these, e) assess the relation between the verb and the terms ‘users’ and ‘requirements’, as well as the similarities and differences between the latter two nouns, to estimate (among other things), which sense of ‘user’ is relevant here (a person that might be managed by another person, or a person as recognized by a software system managing user login accounts), among other things. 
     In a next processing step, VTAS software  20  identifies a linker  47  (i.e., the matrix verb) and recovers relevant information about that verb, especially the thematic roles it assigns, or may assign in relation to different senses. Then the VTAS software estimates on the basis of the syntactic structure of the sentence (or an estimate of it, if the structure does not appear to be well-formed) how these roles are to be assigned in this specific case. Tagging associated with this phase of the process is mostly driven by the need to highlight and articulate the role of the matrix verb in the VTI of any issues related to the present sentence. The VTAS software  20  then identifies and tags situators  49  (e.g., auxiliary or modal verbs, tense marking, negation). In the present example the software must recognize and tag the auxiliary verb ‘will’ and recognize its ambiguity as to whether it is meant to invoke an epistemic sense (re: time) or a deontic sense (e.g., of a command). The results of the linker and situator tagging are added to the VTCO  34 . 
     From the structural class indicators and tagging of the cognitive functional parts of the sentence  51 , the VTAS  20  software forms sets of terms that support an ontology of the sentence, and, in many cases, also support distinct alternate ontologies that can be the source of types of miscommunication that are identifiable as risks within the scope of the present invention. In the example sentence, the VTAS  20  software analysis identifies that the main subject of the sentence is a special type of ‘widget’ called the ‘admin widget.’ The structural class tagging further indicates a functional relationship between this widget and the conceptual objects ‘users’ and ‘requirements,’ described by the verb ‘manage.’ The situators tagged within the VTCO  34  indicate that the sentence is set in the generic future. 
     Many aspects of this sentence&#39;s ontology require access to a context extrinsic to the sentence to assist in determining context and meaning. Using the VTDM processing, a search and comparative analysis within the document on use of the same pointer ‘admin widget’ or on other pointers may be performed to provide additional aspects of the meaning or possible meanings of the pointer and the use of the pointer within the sentence. For instance, to what extent is ‘widget’ a generic term used to refer to many user interface components within the software described in the document and further, is the ‘admin widget’ itself a unique element or one of a class of ‘admin widgets.’ Additionally, are ‘users’ and ‘requirements’ usually associated with generic ‘widgets’ or exclusively with ‘admin widgets.’ All uses of the pointer would be identified, tagged and accessible for further analysis within the VTCO  34 . 
     In cases where supporting material is available, the VTDM  30  analysis process may extend beyond all of the present document using the Corpus Model  32  processing software to a comparative analysis a corpus of other similar documents to determine the probabilities of how ‘widgets’ are associated with ‘users’ and ‘requirements’ within a certain type of software as well as the prevalence of ‘admin widgets’ vs. generic ‘widgets.’ 
     Additional searching would be automatically performed to identify uses of the term ‘admin widget’ within an explicated ontological library for the company containing the present document and/or for the industry. Alternatively, searches may be performed for the constituent terms ‘admin’ and ‘widget’ within the Vital Text Concept Library (VTCL)  90  of explications, where the present context can then be compared to that described through explications in the library entries. If the company associated with the document has an ontological library that does not yet include ‘admin widget,’ the term can be added during the VTAS  20  process and serve as a resource for future documents within a given scope. 
     Each statistical observation of use identified through these process steps in the document or corpus levels are translated into scores or weightings associated with each element of the sentence  51 . These quantitative scales are used later in the VTAS  20  process to assess the degree of risk associated with any potential risk element within the text. 
     Once the VTAS  20  software has identified the components of the sentence and applied quantitative values to a comparative analysis based on the context within the present document and within any larger corpora beyond the present document&#39;s scope, the VTAS  20  software using the Risk Detector (RD)  38  applies Risk Patterns  63  to identify Risk Elements  65  within the text. In the present example, the VTAS  20  software the modification of ‘widget’ by ‘admin’ may be identified as a Risk Element  65  requiring further analysis, if these terms were not commonly used within the document  22  or document corpus. The context extrinsic to the present sentence acquired through the VTDM  30  and Corpus Model  32  provides the analysis to determine whether there are multiple different components within the document or a particular type of software that are referred to as ‘admin widgets.’ 
     A further potential ambiguity concerning the coordination by the ‘and’ of the ‘new users’ and the ‘requirements’ is evaluated through the VTAS process to determine if the ‘admin widget’ manages ‘new users’ and ‘new requirements,’ or ‘new users’ and all ‘requirements.’ The VTAS  20  uses the E4E sentence and document models to then assess the risk of confusion to the eventual reader of the document raised, for instance, by these two Risk Patterns  63 . As well, because the sentence model defines the relationship between these two types of ‘pointers’ in the sentence, the subject (the ‘widget’) and the objects (the ‘users’ and ‘requirements’), the VTAS  20  software can assess the risks of the two Risk Patterns  63  in combination. Using this method, the VTAS  20  software determines if the term ‘admin widget’ is unambiguous in the present sentence because, a) the entire requirement is about this singular ‘admin widget,’ or b) within the company&#39;s corpus of documents (or type of software they describe) the term ‘admin widget’ is well understood and has not been associated with errors in the software testing process. On the other hand, this process may also determines if the term ‘admin widget’ is ambiguous in the present sentence because, a) within either the present document or corpus of documents there are many different entities referred to as ‘admin widgets,’ or b) the use of ‘admin widget’ in the present sentence is different than in the document as a whole or in the corpus as a whole. 
     In terms of the assignment of the modifier ‘new’ to ‘users’ and ‘requirements,’ the VTAS  20  software through the VTDM  30  and Corpus Model  32  processes can look for evidence to support alternate scenarios: first, this widget allows a user to manage (i.e., create) new users and new requirements from the same interface; second, this widget allows a user to create a new user and assign that user to existing requirements; or three, this widget allows a user to create a new user and assign that user to existing requirements or to create a new requirement to assign the new user to. The Risk Assessors (RA)  39  of the VTAS  20  use the contextual document-level and corpus-level information to determine the likelihood of each of these scenarios and identify a level of risk associated with the match of the Risk Element  65  to the Risk Pattern  63 . 
     For instance, if almost all examples of the term ‘admin widget’ in the document or corpus are adjacent to both terms ‘new user’ and ‘new requirement,’ it might be highly likely that the ‘new’ refers to both objects in the present sentence. If, on the other hand, many instances of ‘admin widget’ are not collocated with references to ‘users’ and ‘requirements’ at all, the VTAS  20  software may accumulate information that shows there are many types of ‘admin interfaces’ in the scope of the present document or corpus and determine that the use of the term in this sentence context is vague if not actually confusing. Additionally, this process would also identify the future tense of the situator to be generic to most software requirement documents and to not be a cause of concern or confusion in the present context. 
     The ability to understand which terms are used in a manner congruent with the common practice of a target population of readers is crucial to creating helpful tools to improve the fidelity of written technical documents. If, in the present example, ‘admin widget’ is the entire subject of the present document or is used with a high level of consistency in the enclosing corpus, it would be pedantic to alert the user to a potential risk that in fact poses almost no risk. Part of the scope of the present invention is the injection of an understanding of how user experience impacts the actual utility of these sorts of analysis systems. Every item in a document identified for the user to consider spends their attention and may leave them inattentive to a more important issue farther on in the text. 
     One of the important objectives of the present invention is to not only identify potential Risk Elements  65  within a text, but to only identify the risk that are truly problematic in the present context. However, the VTAS  20  stores all identified Risk Elements  65  for future analysis as needed. Further, for the Risk Elements  65  called out for consideration, the VTAS  20  offers forms of input that allow the user to remedy the risk potential and thereby improve the VTQI  120  for the document and for themselves as an author. For instance, in the present example, if it is determined that the term ‘admin widget’ exists in many forms in the present document or larger corpus, the VTAS  20  would provide through the Vital Text Interface (VTI) suggestions for adding a further modifier to the term to make it clear that the sentence is referring to the ‘admin new widget.’ This addition would also have the additional impact of clarifying the potential ambiguity of the ‘one and one’ pattern identified with ‘users’ and ‘requirements.’ This one correction could potentially neutralize two identified risk potentials where the VTAS software can assess that a reader would be highly likely to understand that the ‘admin new widget’ allowed a user to manage both ‘new users’ and ‘new requirements.’ 
     It is a further important aspect of the present invention that as such Risk Elements  65  are identified for the author or user, contextual content from the E4E curriculum  99  is made available that helps the author understand the nature of the particular risk of miscommunication and how to avoid it in the future. In this way, the VTAS  20  system is able to turn each potential mistake into a positive teaching moment. The author gets the satisfaction of fixing the present document, improving their skills and understanding as a writer, and also raising the VTQI score and with it their value to their company. 
     The tagging of terms and structures provided by the VTAS  20  using the E4E framework  50  make explicit a great deal of information about how the structural classes  43  realize the three core cognitive functions in each sentence across a text. This enables the Risk Detectors  38  to apply known Risk Patterns  63  to the sentences  51  in a text  22  in order to identify Risk Elements  65  that contribute to potential sources of misunderstanding within the text. As shown in  FIG. 8 , the Risk Detectors (RD)  38  are algorithms that scan the tagged text in the VTCO in search of a diverse range of structural features that may be relevant to the Risk Pattern  63  that each Risk Detector (RD) is responsible for, these being patterns or relationships have been found to be common sources of misunderstanding or confusion. Individual Risk Detectors (RD)  38  may target small and highly constrained structures (even single words for some Risk Detectors) or larger and more complex structures that could be bounded by a single sentence  51 , or even target structures and relations that span multiple sentences  51  at widely separate locations within sections  53  or within the text as a whole. 
     The Risk Patterns  63  may be known and be taken from a Linguistic Repository  60  within the VTAS  20 . These general Risk Patterns  63  are usually expressed as syntactical structures and are generally defined over POS categories, but they may in some instances include specific lexical items. For example, a general Risk Pattern  63  may be in the form of a structure such as ‘MODIFIER WORD1 CONJUNCTION WORD2’ of which the more specific pattern ADJECTIVE NOUN and NOUN is an example. The noun phrase ‘damaged capacitors and resistors’ would be an instance of the general pattern and the more specific variant, and one that exhibits an ambiguity characteristic of these structures in that it is unclear whether the writer intends to indicate that both the capacitors and the resistors are damaged. Further specific Risk Patterns  63  may be derived from analysis of the Enterprise Repository  70  where specific terms used in the corporate ontology appear. Risk Elements  65  identified from these Risk Patterns  63  may be given a higher or lower ranking in particular texts on the basis of analysis possible interactions among Risk Patterns  63  detected in an analysis of the Enterprise repository  70 . In many instances Risk Patterns  63  may be patterns that arise wholly within single linkers  47  situators  49  or pointers  45 , but they are not limited to such cases. 
     Further risk detection may be performed from lists of commonly known terms that have been identified as being ambiguous or that support many types of ambiguity. These terms may be stored in the Linguistic Repository  60  and the Risk Detectors (RD)  38  may perform a series comparative analysis using these terms and/or other constructs identified as risks correlated based on a set of compiled grammatical or syntactic rules from an analysis of technologies within an industry, and from a variety of document risk types within that technology. This analysis may include identified ambiguous terms such as “user-friendly” or any such representation of this term, “easy”, “simple”, “rapid”, “efficient”, “maximize”, “minimize”, “improve”, “state-of-the-art” or any such representation of this term or any modal verb such as “may”, “can”, “could”, “must”, “will”, “shall”, “most” or other terms that are known to lead to confusion. The results of this analysis are stored in the VTCO  34  with any identified salient term noted as a Risk Element  65  indicating a possible ambiguity. 
     The Risk Detectors (RD)  38  perform a potentially highly iterative, process whereby the VTCO  34  including annotations related to structural classes  43 , is analyzed by a number of specific functions to apply these Risk Patterns  63  and identify specific instances of Risk Elements  65  at the document, sentence and text levels. Collectively, the Risk Elements  65  are returned in the Analyst Target List (ATL)  42  that identifies specific suspect items or structures at specific locations in the text and links each to one or more specific potential issues for consideration by a Data Analyst  48 . The ATL  42  may be constructed at various levels of analysis and may therefore be amended to remove potential defects that have been judged trivial in the earlier phases of the process steps. Using the Risk Assessors (RA)  39 , those discovered Risk Elements  65  are assessed for the likelihood an error of interpretation will occur and for the severity or consequence of any such error. For instance, a Risk Detector applying a simple Risk Pattern  63  that identifies all instances of ‘it’ in the text could also contain (or be succeeded by) a Risk Assessment  39  that downgraded instances where the ‘it’ only has a single potential antecedent within relevantly close context and which therefore presents no great potential for generating ambiguity or confusion. The results of this assessment are added to the VTCO  34  as a name-spaced layer contributing to the Analyst Target List (ATL)  42 . 
     The Risk Elements  65  identified in the ATL  42  are tested or scored against tolerances for each risk type. The term ‘risk’ is used loosely and broadly, meaning that any feature of the document  22  that potentially threatens the quality, reliability, functionality, suitability-to-task, or cost of the finished system a requirements document is meant to describe may be considered a risk. Often these ‘risks’ are features of the document  22  that allow for, or even invite, misinterpretation, or that create conflict or confusion in relation to other elements of the document, or that tacitly invoke unstated assumptions. Rarely will these be ‘risks’ in the ordinary sense of grammar checkers in which, for example, ‘they&#39;re’, ‘there’ and ‘their’ are frequently substituted for each other. Scoring of the kinds of risks targeted here is accomplished through some combination of automation (i.e., additional functions and machine learning) and human judgment, also including intervention by data analysts  48  possessing appropriate domain knowledge and expertise. This process, as with the risk detection process, can be highly iterative or involve the input of multiple analysts and different domain experts to assure that only significant Risk Elements  65  are retained for the final analysis. 
     The Risk Elements  65 , deemed to be of sufficient severity, are output to a Client Target List (CTL)  44  which identifies specific Risk Elements  65 , risk types and locations within the text. The results of this step are added to the tagging in the VTCO  34  as a name-spaced layer indicating client level Risk Elements  65 . Each distinct risk type has a corresponding Risk Display Method (RDM)  67  that is instrumented in the Vital Text Interface (VTI)  40  within a clean electronic copy of the original text as high-lit, color-coded and linked words or runs of text that target panels or other user interface devices to display an explication of the specific Risk Element  65 , an explication of the risk type and a range of means for resolving the defect, and (where relevant) all Risk Elements  65  of a similar type in the document or section. Changes within the input mechanisms in these display devices immediately produce changes in the visible text of the document. 
     As shown in  FIG. 9 , each identified risk type  67  consists of four modules: a risk detector  69  which identifies a pattern of linguistic entities which are associated with a high frequency of risk; a risk assessor  71  which refers to markup in the VTCO  34  as well as any relevant corpora to determine the likelihood that the given risk pattern is problematic in the current context; a risk type display element  73  which appears in the VTI adjacent to the location of the risk pattern in the text and explains the nature and severity of the risk and offers methods of remediation; and content from the E4E curriculum  75  matched to the risk type that helps the user understand the linguistic nature of the risk type and how to avoid this type of risk in the future. The Risk Assessor  39  performs an assessment based on the E4E framework  50  through an analysis of the Risk Elements  65  with respect to each structural class  43 , as shown in  FIG. 10 . A first analysis assesses the severity of risk of each Risk Element  65  with respect to the usage and context of the pointers  45  within the Risk Element  65 . A coordinate indicator  82  that may be color coded or otherwise highlighted to indicate risk within the document  22 . The pointer assessment is shown within a Pointer Layer  81  display of the Vital Text Interface  40 . An assessment is performed with respect to the linkers  47  and coordinate indicator  82  is displayed within a Linker Layer  83 . A further assessment of a Risk Element  65  of with respect to the usage of situators and their context within the Risk Element  65  is performed and a coordinate indicator  82  is displayed within the Situator Layer  85 . In a first embodiment, a ranking  84  of +1 may be used to indicate each Risk Element  65  within each display layer. By separating the risk assessment into the distinct structural classes  45  and layering the results of the assessment with a ranking  84  for each Risk Element  65 , the rankings may be combined and a total ranking may be calculated where Risk Elements  65  that invoke one or more structural classes indicate an exponential increase in risk that can be calculated as an Exponential Ranking  88  and be displayed as Ranking Result  89 . Therefore a Risk Element  65  that invokes both pointers and linkers within a Risk Element  65  would receive a ranking of 4 as indicated within the Risk Summation Layer  87  in Vital Text Interface and a ranking that invokes pointers, linkers and situators would receive an Exponential Ranking  88  and Ranking Result Ranking  9 . 
     The Vital Text Interface (VTI)  40  has three critical functions; 1) the VTI  40  allows the document author to easily find each Risk Element  65  in the text of the original document  22  as described (whether the Risk Element  65  is a single local issue, defect or error or an issue, defect or error that relates to many specific instances across the document); 2) the VTI  40  provides information about the nature of the Risk Element  65  which will typically begin with a concise on-screen report, using a pop-up or similar device display, that will also provide a link to the relevant parts of the E4E framework  50  that allows an author to pursue further information as needed; 3) the VTI  40  also provides guidance and resources relevant to repairing each identified issue, risk or defect using the E4E curriculum  99  based on the E4E framework  50 . These resources provided by the E4E curriculum  99  may include offering a list of possible alternate terms, a listing of two or more possible interpretations, a suggestion about how a particular possible interpretation can be blocked, and explications related to the Risk Element  65  and salient terms within the document  22 . 
     The E4E curriculum  99  is a comprehensive, but very compact, pedagogical grammar of English. It is practical and focused on the work that documents do. It aims to show how a small set of intuitively accessible fundamental principles account for most of the structure of English texts. It does not neglect the irregularities and eccentricities that attract much attention in traditional grammars and style books, but attempts to position these matters clearly in relation to more general and more central matters of sentence and text structure. This grammar is presented in the form of a large set of very compact ‘articles’, ranging in length from just a few words to a few sentences. These are hierarchically arranged and indexed in such a way as to allow an author to enter the E4E curriculum  99  using the VTI  40  at any point relevant to a particular issue, and then to follow related threads either up to more general issues, or down toward finer specifics of realization within a current or previously authored document  22 . The author may select any suggestion, alternate term or phrase using a mouse and the Risk Element  65  is replaced and corrected. 
     A particular focus of the E4E curriculum  99  is on the concept of a document ontology  101 . Technical documents in particular are often ones that assume that the reader commands a relatively large body of specialist background information that includes knowledge of a complex field of entities that are defined by their spatiotemporal properties, their behavior, and their interactions with other entities. Many documents then attempt to carry the reader from this background ontology  103  to an appreciation of the altered document ontology  101  that incorporates either a changed view of some of the assumed entities, extends the background ontology  103  with new entities, or in some instances argues for dispensing with some previously assumed entities. The obvious fact that different readers commonly approach a given document with different backgrounds and assumptions, i.e., with different ontologies, constitutes one of the central challenges in assessing any document. But in technical documents this challenge is often particularly acute when the document is meant to be accessible to multiple reader groups (i.e., groups that vary in their specialist background, expertise, and goals). 
     As shown in  FIG. 11 , each ontology provides critical concepts  105  that if misunderstood may result in increased risk of improper use or injury in using a technology. From the reader&#39;s perspective the assessed risks  107  increase if the reader approaches a document from knowledge of an alternative background ontology  103  and the document does not adequately provide the changes and separations of the new technology from previously assumed concepts and entities in that alternate ontology  103 . Particular separation and comprehension must be provided to reduce the severity of the High Level Risks  109  where the ontologies overlap. The E4E curriculum  99  provides both the information for the author to properly realize the risks associated across ontologies through the use of definitive sentence structure and the tools to improve writing skills to consider the importance of a reader&#39;s perspective in comprehending the critical concepts  105  and depth of meaning of the requirements within a document as it relates to the document ontology  101 . 
     In a first embodiment, the ontological development process begins with a list of terms created from the VTAS analysis stage. This Ontology List  79  of terms is then reviewed by the author or a data analyst  48  and the terms are arranged in priority order. Terms are selected and ‘allocated’ to a list that may be presented to experts to provide explications  92  of terms selected in each requirements document. A table that coordinates the list of allocated terms with experts is maintained. Each expert is then notified through a voicemail message, text message, email or other notification method and the expert is presented with a web link to access the document and terms within the document needing explication. The notification may provide the expert with a ‘closing date’ by which time they must complete the explication  92  or solicit a ‘commitment date’ from the expert to complete one or more explications. The VTAS provides a template  91  to the expert for the completion of the explications  92 . The template is pre-filled with all information that is available about the term from internal sources of the current Vital Text Concept Library (VTCL)  90  and from external sources such as common databases available through a company&#39;s network or from the Internet. The explication display system within the VTI  40  of the present invention also provides for multiple explications  92  for any single term, where a selected term may already possess an explication completed by a previous expert, if a different usage is in play within the document under review then an additional explication is entered. 
     These alternatives and additional elements of language can be presented in the manner of a Concept Map  100  that both articulates the specific properties of terms, as well as displays their relations to each other, and to general (non-company-specific) usages of the same terms. A Concept Map  100  creates a visual representation of the relationships between the salient terms within the document. Automated processes using the VTAS as well as the manual review in developing the Concept Map  100  reveals weaknesses and omissions within the document. Concepts of higher level are often decomposed into their representative parts or components. Through processing of the Concept Map representations, the trained data analyst is focused on missing requirements, underdeveloped higher level concepts, defect producing weaknesses and other risks of misinterpretation. 
     The VTAS  20  provides not only the explications of terms as used in a given contextual event and at a given point in time, but also the tools for tracking ongoing changes in both internal and external usages using continuous updating through the on-going analysis of further requirements documents. The mask and characteristics of the concepts collected by this ontological analysis is fed to the Vital Text Concept Library (VTCL)  90  repositories from which further analysis may be performed. The Vital Text Concept Library (VTCL)  90  is the primary tool that describes the various characteristics of the concepts that wear these masks (terms), and the circumstances in which they wear them. It is the context of the concept wearing the mask that enables the discovery that one term or phrase may be playing different roles creating a risk of ambiguity and misinterpretation. The Concept Library (VTCL)  90  of the VTAS  20  further provides for grouping of terms within general solution areas and within general or specific industry vocabulary sets. The terms and explications or definitions may then be statistically ranked and presented to the author or user working on the document with alternative and additional elements of language (nouns, verbs, etc.) and phrases reflecting specificity and relevance to best describe the desired concept. In this way, the Vital Text Concept Library (VTCL)  90  is an alternate pathway that builds a database of company-specific terminology. 
     The Library  90  is formed from information obtained from crowd sourcing, and group sourcing, as well as from analyses of company documents creating a base of information that constitutes an empirically grounded analyses of the unique ways in which terms are used within the company&#39;s internal and external communications. Vital Text Concept Library (VTCL) terms and phrases presented for language refinement further permit an author or data analyst to select and deselect language and effect a new requirements statement based on the enhanced language to address risks and defects within the document  22 . 
     The automated editing process within the VTI  40  that accesses the Vital Text Concept Library (VTCL)  90  may include company specific terms  74 , terms from an external dictionary, a review of terms using public reference information or other sources for reference. The public reference information  76  may be for example through a search of a lexical database such as WordNet that may group terms from the company specific terms  74  and public reference information  76  into sets of synonyms or synsets to be stored within an Ontological List  79 . The Ontological List  79  may be used in the Vital Text Document Model (VTDM) processing to tag identified terms and phrases within the document  22 . The synsets may provide short, general definitions and semantic relationships between the salient terms within the Ontological List  79 . The Ontological List  79  may further be used to contribute to the development of unique target words and phrases  77  of interest that may be chosen by the author to request explications in order to identify critically distinctive usages of industry specific and/or enterprise. 
     A chosen target key word or phrase may undergo an analysis to accumulate information employed to construct descriptive information topologies of each target phrase. The information is collected using a conversational guidance process to gain information from those who possess exceptional understanding or are interacting with and using the product using what is known herein as a group sourcing method. Additional information about the target phrases is collected from those who are peripheral to the use and understanding of the technology product using what is known herein as a crowd sourcing method. Group sourcing is not used in this meaning as a general term where participation is open to anyone, but instead is restricted to those members within the technology community that have been selected by the author or one or more group source members who request the elicitation of information from these participants. Crowd sourcing is also not the general public but instead are users of the technology that are associated more broadly within the company. Although, in some instances where security of corporate concepts or terms is not a concern then true public crowd sourcing methods may be employed to enhance understanding in the document(s). 
     Using the Ontological List  79  as shown in  FIG. 12 , the VTAS application software  20  generates a guidance explication template  91  that includes specific questions directed to inconsistencies in use of the target key word and provides specific questions associated with the technology and the target key word or phrase. The explication template  91  may be directed to a group member and/or a crowd member is constructed and is reviewed and amended as required by a data analyst  48 . The explication templates  91  are forwarded to a group source participant(s), such as an appropriate expert of the company, a crowd source participant(s), or general user that may be internal or external to the company but that is associated with the technology of the company. 
     The guidance explication template  91  may be an interactive conversation between a data analyst  48  and one or more group source members, with the data analyst collecting the information, or the data may be gathered remotely where the explication template  91  is forwarded to one or more crowd or group source members and is monitored by the author or data analyst  48 . The guidance explication template  91  may be tailored specifically for the recipient of the explication template so for example a group source explication template may have additional requests for information when compared to a crowd source explication template. The structure of the explication template  91  using the VTAS  20  provides for automated extraction and compilation of each answer provided by one or more participant. Each answer to a question may be combined and presented in a color coded format, where for example each color denotes group participant information  93  or crowd participant information  95 . The color coding assists the data analysts  48  in the review of the explication template results  91  that are the definitions and data collected evaluate information that may be used to assist in developing definitions and explications for the targeted terms. The information gathered from the explication templates  91  is stored in the Vital Text Concept Library (VTCL)  90 . The VTAS  20  employs a variety of methods to automate the collection of data and support the data analysts  48  who may be experts from the corporate enterprise and experts within the community at-large. The VTAS application software  20  provides unique discriminator algorithms and a range of methods to manage, measure and control collection ratios from specific corporate locations, enterprise wide locations and selections from the world at large depending upon how broad or specific the requirements information and acquired information is to populations of usage. 
     In an embodiment of the present invention, the methods of the VTAS application software  20  assist in determining when the circumstances warrant the establishment of outside populations who can address information acquisition from a more diverse pool of members outside the corporate structure. The VTAS  20  may apply an extended contribution base of crowd source members that are peripheral to but acquainted with aspects of the technology products. This contribution base may provide broader modeling and longevity to the analysis that may be extended over time. However, at times the representations to be constructed will not benefit from a peripheral virtual workforce that extends beyond members of the immediate corporate community and this broader modeling may not be used. 
     Following the collection of information into a descriptive information format, from one or more group and/or crowd source members, the attributes are stored within the Vital Text Concept Library (VTCL)  90  and provided with appropriate indexing. The VTCL  90  may be newly created for the specific project within the domain or be updated from an earlier related project. The collected information is indexed using metadata in several unique ways to identify, the date, time, place and context of the acquisition of the information and to identify the party contributing the information including their background and relationship to the project. This broad information is used as each explication template response associated with a target phrase is evaluated for the purposes of creating a target phrase explication. This descriptive explication  92  is most heavily based on information provided by the group source explication template results to properly define the target phrase within the context of the internal company nomenclature. Explication template results are further analyzed to create alternate explications or representations  93  with specific criteria that make the alternate signifier for the given target concept more predictable as it pertains to the image it is meant to provoke in the mind of the reader of the requirements document  22 . The purpose of developing alternative explications to the original target phrase  77  is to provide alternative representations  93  satisfying the six attributes of quality communication as described in further detail below. 
     Using the Vital Text Interface (VTI)  40 , the targeted terms are highlighted, color coded or indicated otherwise in the requirements document  22  and are tagged or otherwise annotated in the VTCO  34  to assist with a manual review that is performed to identify terms related and connected to terms identified as Risk Elements  65  that may be problematic to comprehension and/or are known to be correlated with defects. As part of the manual review, the highlighted terms are displayed in a Concept Map  100  and are identified as nouns, verbs, adjectives, adverbs or other parts of speech (POS) and may be designated with color coding with distinct shapes to identify relationships that visually represent ontologies of the document. Shaping and color coding may present such visual information as terms and concepts which occur at specific levels of decomposition within the document. Information such as levels of decomposition assist a data analyst  48  trained in the Linguistic Sciences to quickly ascertain terms and concepts which are viable to be matched and correlated against decomposition criteria and defects. Executing this type of analysis may more readily identify underspecified concepts and underdeveloped terminology. 
     Each term is added to the Concept Map  100  only once and lines are used to denote the “is-a”, “part-of”, “has” and other possession and recurring relationships. Using the Concept Map  100 , the identified nouns and selected target phrases  77  are identified and tagged using meta-data with attributes defined from the results of the VTSM  28  and VTDM  30  analyses based on the E4E framework and from the Risk Elements  65  identified by the Risk Detectors (RD)  38 . The Concept Map  100 , as shown in  FIG. 14 , may display identified nouns  102  in a specific color and shape. Connecting lines  104  identify relationships between terms within the document  22 . Other forms of speech such as verbs and adjectives related to the identified noun may be shown in other colors and shapes. A legend  106  labeling shapes and colors may be provided. A navigator  108  to search and find identified terms within the document may also be provided. The Concept Map  100  may be constructed based on specific sections of one or more documents where a careful review of selected terms and their relationships may be performed. Relationships between structural classes  43  within Risk Elements  65  may be identified and highlighted, for example where a group of pointers  45  identifying the structure of a device such as component 1 with component 2 and with component 3 are put together to make assembly 4, sections within the document that only note components 1 and 3 without component 2 may be highlighted. Further, relationships between an identified pointer  45  with a specific situator  49  such as a modifier adjective or an identified pointer  45  with a specific linker  47  may also be identified and highlighted. The Concept Map  100  also identifies pointers  45  that are not connected in relationships to other terms, and any terms that are used in such a manner that are connected to two or more other terms in a way that would identify a Risk Element  65  that may create an ambiguity, such as through multiple theta roles or noun clusters. 
     The visual inspection of the Concept Map  100  allows an analyst  48  to evaluate the completeness and appropriateness of a corporate or technological ontology of these identified target terms. The Concept Map  100  also provides for the VTAS  20  to use automated methods to process the map  100  and perform specific analysis throughout the document or a corpus of documents to begin to construct successively extended diagrams across group, division, company, enterprise terminology and their associated references. These identified target terms and the relationships identified in the Concept Map  100  are stored in the Vital Text Concept Library (VTCL)  90  where they may be selected for risk assessment to identify the intersections of the depth and breadth of each identified target term and phrase and their relationships with other high, medium and low frequency target phrases  77 . The identified targets may be pointers that as described above are the world of conceptual words and phrases that exist within the requirements engineering documents  22 . The Concept Map  100  includes a processor that traverses the Concept Map entries and evaluates the structural classes  43  and relationships within the document  22  based on the E4E framework. From this evaluation three dimensional (3D) models are constructed to display the strength and redundancy in the relationships of the things within the document to assist in the review of these relationships. The constructed 3D models may illustrate the parts of an assembly that can be separated into an exploded parts diagram or software modules that may be diagrammatically displayed to show cross-overs and interactions of components or modules to identify risks or inconsistencies in design in the operation of the software. These discrete associations may pictorially represent the relationships or lack of connection between concepts within the requirements documents. These physical models may assist stakeholders in improving the integration of the conceptual components to reduce failures and improve software and product design and reliability. 
     From the relationship data presented in the Concept Map  100  key words or target phrases  77  may be identified and categorized and grouped using the VTSM  28  and VTDM  30  processing and be stored within the Vital Text Concept Library (VTCL)  90 . A comparative analysis may be performed on each identified key word or target phrase  77  to match the phrase to company specific terms associated with the engineering requirements. The Vital Text Concept Library (VTCL)  90  may also be used to search for the identified target phrases  77  and label these targets in other requirements documents  22  within the current project or in other project domains. Iterative searching may be performed as new documents are added to the project and new target phrases  77  are identified. This iterative process provides target phrases  77  and key words that are identified as crucial to the comprehension of the needs, the stakeholders are communicating through the document(s) under consideration. 
     An initial comparative search may be performed on the Ontological List  79 . The search compares the target words and phrases  77  to company specific terms  74  that are compiled and stored within the Vital Concept Library (VTCL)  90  to identify engineering and technological terms specific to the industry or applied science discipline of the company or stakeholder. Definitions of terms discovered in this search may be associated with the selected targets  77 . The group and crowd explication information  93  and  95  provides further information to assist in identifying target words and phrases  77  that require further analysis. A data analyst  48  performs a further review of the assessment targets  77  and the search results and may tag some targets as having no or minimal interest and therefore mark them for removal from further analysis. The data analysts  48  then determines a set of most critical targets and phases  77  that indicate some form of ambiguity and require closer analysis and inspection. The selected targets  77  may be presented to company members  46  to determine if the targets  77  are acceptable or if there are substantial omissions. These selected targets with the data associated with these targets are stored within the Vital Text Concept Library (VTCL)  90 . 
     The selected targets  77  are chosen based on information provided in the Concept Map  100  related to frequency of occurrence, location, concordance values, collocation, depth of occurrence, breadth of occurrence, the data analyst&#39;s review and other parameters to identify the most critical targets. This target compilation  77  may further include lemma variants of the target information to assist in determining proper use and definitions of the selected targets  77  within the requirements documents  22 . A first target  77  is selected and an ontological analysis is performed. The VTAS  20  highlights each instance of the selected target  77  within the requirements document  22  and based on an E4E framework analysis of the structural classes  43  of the targets  77  within a sentence  51  and section  53 . Risk Detectors (RD)  38  may further apply Risk Patterns  63  to the targets  77  to develop an inconsistencies report  94 , where Risk Elements  65  are identified where the targets  77  may be ambiguous, a clear definition of the target is not provided, or the meaning of the target may be misinterpreted. 
     The results from the series of linguistic analysis performed and the complete sentence and paragraphs surrounding a target provides for clear and direct assessment of each of the identified targets  77 . For example, thresholds may be set for frequency or distribution, to assist in identifying targets and any targets that exceed these thresholds are highlighted and color coded. The thresholds are determined using the VTAS through an iterative analysis based on frequency and usage of terms within a number of requirements documents within the analyses. The VTAS  20  may further provide a comparative match of N-grams and identify inconsistencies where the target  77  may commonly be associated with a specific term within 1 or 2 words of the target  77  and any instances where this relationship does not exist may be highlighted. These relationships are provided on the Concept Map  100 , so verification of the analysis may be easily confirmed. 
     These identified terms are also highlighted to the author of the document as critical terms that should be contextually reviewed to make certain they are clearly defined and communicated. The VTAS  20  further provides the author and requirements engineers  46  with the ability to locate and place additional terms from the requirements document  22  into the Ontological List  79  for explication or further analysis or allow the author to remove immaterial targets from further analysis. 
     The VTAS  20  using the E4E framework employs automated methods to augment the understanding of the target phrases  77  selected through this analysis process. Modified original definitions or explications  92  are developed from this analysis and from the explication template data collected  91  by local group members  85 . The explications  92  are a best alternative phrasing that is developed through an automated evaluation using semantic and syntactic principals to indicate risk levels of the use of redundant and/or circular terminology to define critical terms or the omissions of critical description for critical terms within the requirements document  22 . 
     Representations  93  that provide alternative definitions and related interpretations to the target  77  are also developed and a topology is formed based on each target phrase  77 . As described above, the topology may include one or more alternate uses of the target key word or phrase  77  as used in one or broader technology disciplines. By providing this range of uses of a target, a data analyst  48  or systems developer  46  may better understand how a term may be interpreted by a user of the technology product that is outside or not related to the company. The topology further highlights problem areas where a misinterpretation may present a greater risk to the user where a greater number of topological alternatives demonstrate that a term may be widely used, but poorly defined. 
     The explications  92  therefore crafted to meet specific quality requirements to augment the enhanced meaning component developed through the ontological analysis and other VTAS processes. Obtaining guidance from a variety of sources, these explications  92  and representations  93  must possess the following qualities: Freedom from obscurity; Freedom from circularity; Freedom from otherwise non-predictiveness. Additional constraints are: No excessive information, meaning that a definition must contain no information that could over-constrain the target phrase  77  concept being described relative to that provided during creation of the descriptive information record; No insufficient information meaning that the candidate target phrase  77  lacks no information that by its absence could under-constrain the concept being represented that was provided during creation of the descriptive information record; No erroneous information meaning that it contains no information that is not consistent with that provided during higher meaning attribution; and finally these alternative to the original phrasing within the documents  22  must be written entirely in relative semantic primitives. “Relatively primitive” is equated to a level of complexity at which agreement occurs spontaneously between two separate minds about the meanings of words (without need of paraphrase or other description). 
     Explications  92  and representations  93  are added to the VTCL  90  and are highlighted within the documents  22  to be reviewed by the data analyst  48  for accuracy. The Vital Text Interface  40  displays the explications  92  and representations  93  using a hovering dialog box that provides for a member of the company  46  to review and accept or reject the insertion of explication  92  or representation  93  definitions and phrasing. Using this unique feature of the VTAS  20 , corporate company employees have access to an updated global Vital Text Concept Library (VTCL)  90  containing all the explications  92 , representations  93 , their usages, their descriptive information, using the E4E curriculum  99  and the statistical rankings of the VTQI  120  as described herein and many other elements of information about the concepts that exist within their corporate enterprise. 
     Within the VTI, visual representations known to provide enhanced human factors are employed to provide clues to the requirements document consumers about which terms possess further clarification in the Vital Text Concept Library (VTCL)  90  or in other ways and means. Using this specific feature, the ability for the consumer to hover over the term to extract and display information specific to comprehension of the term from the perspective of the reader is a unique feature of the VTAS  20 . The Vital Text Concept Library (VTCL)  90  is iteratively updated with these explications  92  and representations  93  and these may be used throughout multiple projects to enhance descriptions and provide searching strategies to reuse preferred terminology to improve future requirements documents and specifications. Through the VTCL  90  and E4E curriculum  99 , the VTI  40  provides additional visual and textual information about the terms and concepts within the requirements document allowing the author to more effectively visualize and understand the topology of the terms employed thus raising comprehension and correct Risk Elements  65  and defects based on this information. 
     As the detected Risk Elements  65  are resolved, a display of the Vital Text Quality Index (VTQI)  120  shows a real time index of overall document quality. Additionally, each risk type is linked via an info button or equivalent device to content from the E4E curriculum  50 , including text descriptions, examples, tutorials, videos, apps, and games that educate the user as they work with the product. The quality of each user&#39;s work is monitored by their own individual VTQI  120  as is their educational level as evidenced by their use of these educational materials. 
     A ranking value is established for the explications  92  and representations  93  based on the adherence to the quality requirements, similarity to the original definitions and the topology of usage of the phrasing within the requirements documents  22 . This important feature of the VTAS  20  provides for a user of the system to select a term definition of lower ranking and easily review and compare commonly interpreted meanings from sources peripheral to the stakeholders. The ranking  120  may further identify omissions of information that may be critical to understanding the use and implementation of the technology product through the topology provided and provide for the refinement of the original meaning of a target phrase  77  initially used within the document  22  or provided by the group source members. Using the discriminator algorithms of the VTAS  20 , the selection of an explication  92  or alternative representation  93  may also be ranked as more preferred or less preferred, for example. Additional rankings may be based on a comparison of the frequency of usage of specific internal company terms being used to define a target, with a lower ranking given to those explications that become circular and fail to use the general meanings of terms or use the terms in a context that is incomplete, or in contrast to how the term is commonly used. The ranking is integrated with other statistical measures of the comprehensibility of the requirements documents  22  and with the number of identified Risk Elements  65 , the diversity of users of the documents  22  and other measures. Each of these rankings contributes to the Vital Text Quality Index (VTQI)  120  to produce a reliable, reproducible overall ranking providing a valuable indicator for required improvements and risk evaluation within a corpus of requirements documents. 
     The VTAS  20  further establishes an enhancement network  150  of members of different domains of experience to a common usage and to other supporting information and attributes of the target key word or phrase  77 . For example, a medical researcher delivering requirements to be consumed by a software engineer demonstrates that persons from two occupations may not often communicate about the concepts and items at an equal level. By locating terms within a hierarchical structure of related terms to ‘normalize’ the communications between them the VTAS enhancement process  150  of the present invention produces a more comprehensible common usage scenario of the terms employed. 
     An evaluation and ranking may be applied to the target words and phrases  77 , their frequencies and locations, the identified topologies and the quality of the explications  91  and representations  93  to contribute to the Vital Text Quality Index (VTQI)  120 . As noted herein, the VTQI  120 , as shown in  FIG. 9 , is derived from an analyses focused on distinct aspects within the requirements document  22  related to assessing the frequency and severity of the ambiguities and related uncertainties, specifically the Lexical Ambiguities  122 , Syntactic Ambiguities  124 , Semantic Ambiguities  126 , and Categorical Ambiguities  128  within the identified targets, topologies, representations and definitions. The VTQI  120  may be calculated and applied to a document, where a higher point value may denote a higher frequency of Risk Elements  65  that may indicate potential ambiguities and therefore a higher assessment of risk for a document or set of documents. The application of the VTQI  120  provides for a tangible correlation of risk to a correlation of improvement as misinterpretation risks are identified and amended through the identification of Risk Elements  65  and acceptance of more well-suited explications  92  and representations  93  thereby reducing the overall VTQI value  120 . 
     The VTQI assessment  120  is a broad based evaluation that it is not simply the number or quantity of violations but also the quantity per number of real aspects of the requirements that, as shown in  FIG. 14 , evaluate the Transitional Probabilities  130 ; the Discourse and Pragmatic Structure  132 ; the Target Word Frequency  134 , Collocation and Concordance Information  136 ; and Part-of-Speech (POS) Tags and associated Confidence Values  138 . A scale rating that compiles scores within each of these aspects may be based on, for example, a fixed grand total of 100 that incorporates a ratio of the quality of the content of the requirements documents  22  to the identified ‘violations’ would act to increase the VTQI value  120 . In this evaluation, the VTQI analysis includes the length of the document and a comparison to rated difficulties per segments to determine an overall lower score that would be adjudged as better overall document quality than a document with a greater number of violations within the aspects of analysis. For example, a document of 500 pages could have 100 violation penalties and still be better overall, i.e. present a lower risk for significant defect development, than a document of 20 pages with only 10 penalties, in the extreme. In determining this VTQI value  120  additional factors are considered to account for the statistical variants such as multiple authors, differences in document lengths, densities of violations per section of document and other influences. 
     In a first embodiment, the evaluation scheme may employ a raw score from violation counts through the identification of ambiguities an defects that is then adjusted by scores based on these other more global or structural considerations. Rules constructed to determine the VTQI  120 , weight severity of risk based on how costly the violation of each rule has been proven to be for development in the defects generated, the inefficient time utilization and in other costs. A VTQI  120  that correlates with more costly development grows higher in the overall rating. 
     Ambiguities are scored in terms of their frequency and distribution where higher concentrations of ambiguities in specific sections of the requirements document drastically raise the VTQI  120 , as do concentrations of different kinds of ambiguities (lexical, semantic, etc.) within a specific section. Higher values are also given to collections of requirements that contain violations within close proximity to each other and therefore are (presumably) harder to deconstruct whereas more isolated cases of ambiguity raise the VTQI value  120  to a lesser extent. 
     As indicated by color coding, relationships between the types of ambiguities and aspects of evaluation may be indicated. Within this analysis aspects such as Word Frequency  134 , Collocations and Concordance Information  136 , and Transitional Probabilities  130  may be used to determine scores for Discourse and Pragmatic Structure and Structural Cohesiveness  132  rather than evaluations being constructed from these aspects, however influence from these aspects may affect the overall evaluations and scores. Aspects of Discourse and Pragmatic Structure and Structural Cohesiveness  132  may require human interpretation (deployed through a variety of methods like group sourcing, AMT, Cloud sourcing and others) based on questions targeted to reader comprehension. 
     Through risk detection and assessment using and the VTAS  20  and the information provided using the E4E curriculum, the present invention substantially raises comprehension of corporate writing and communication efficiencies resulting in enhanced information comprehension. With enhanced comprehension there is a substantial increase in information velocity because classical “roadblocks” associated with misunderstandings are diminished. Information flows faster and continuous improvement of corporate communications is the result. 
     The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
