Description:
REFERENCE RELATED APPLICATIONS INFORMATION 
     The present application is a divisional application of U.S. patent application Ser. No. 11/759,372, tiled on Jun. 7, 2007, which is incorporated herein by reference in its entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention generally provides click-thru capability in electronic media, including, without limitation, unstructured Hyper-text Markup Language (HTML) files, Portable Document Format (PDF) files, and unstructured text files. 
     Description of the Related Art 
     All references cited in this specification, and their references, are incorporated by reference herein where appropriate for teachings of additional or alternative details, features, and/or technical background. 
     Many important decisions are made on the basis of information gleaned from various sources. For example, financial information is often extracted from a number of sources, investors, auditors, analysts and creditors often depend on such financial information fox making investment, credit, advice and resource decisions. Optimally, any financial report should be verifiable, understandable and material. As would be understood, information misrepresented, or absent from, a financial report could have far reaching implications for people depending on the information, incomplete or erroneous data could result in significant financial loss. The efficient collection and auditing of data regarding a company is of paramount interest to investors and creditors. 
     As in any information gathering, some sources of financial information are considered more reliable than other sources. For example, in light of Sarbanes-Oxley and other financial reporting legislation, financial reports of public companies to national regulatory agencies are considered by many to be generally trustworthy. The difficulty with such reports is that they are often complex, preventing the reviewer to quickly glean the data needed to generate a fully-informed decision. Further, as such reports are mandated at only set points in time, information gleaned from a federally-mandated security tiling may be inadequate at a point is time remote from the filing date of the report. 
     In order to provide persons with readily-digestible pertinent and timely information, a number of organizations are involved in digesting information from multiple sources of data and displaying such information in a user-friendly manner. Such synopsized information may be garnered from disparate sources, or may be calculated from information garnered from disparate or the same source, which may not be wholly evident by the presentation made to the viewer. While the source of the information may be denoted in footnotes, etc. to the synopsis, because of the time involved in retrieving such original sources and reviewing the same, most, reviewers rely almost wholly upon the information that is portrayed to them. 
     For example, data for any particular financial summary may be gleaned from hundreds of pages of financial performance data that are compiled and published multiple times per period. The conventional practice of transferring and collecting data from electronic documents typically requires manually typing data into a new document or performing a traditional cut-and-paste operation if the source data has this capability. Both of these methods are error-prone (with respect to cut-and-paste operations, for example, a failure to cut a single number may have an order of magnitude effect on an overall financial view). Time spent performing these intensely manual processes would be better spent by auditing the data verses performing costly administrative tasks in support of such operations. As would be understood, with so much data to manually collect and audit, errors in transcribing and copying data can hardly be eliminated in any financial compilation. Further, a failure to fully understand the source of information, or the manner in which it was generated, may have serious unintended consequences in decisional matters. 
     Public companies worldwide are often required by their national laws to produce and publish financial statements so individuals and institutions car, make reasonable decisions regarding their relationships with public companies. The majority of this reporting is accomplished by submitting electronic documents to the appropriate government regulatory authorities, such as the U.S. Securities and Exchange Commission. The electronic document format acceptable to different regulatory authorities differs between countries. Presently, such documents may take the form of Portable Document Format (PDF) native files. Portable Document Format (PDF) image files, structured Hyper-Text Markup Language (HTML) documents, unstructured text files and the like. The documents may additionally be heavily formatted for presentation purposes. 
     Hyper-Text Markup Language (HTML) is a language for the presentation of electronic documents. It is a scripting protocol defining the structure and layout of a page, such as a web page used on the World Wide Web. By use of tags and attributes, a page is assembled to convey a document in a specific format designated by the author. HTML documents were originally intended to facilitate textual presentation using a cross platform protocol when browsing the Internet. 
     A Portable Document Format (PDF), the de facto standard for file exchange, is a self-contained cross-platform document similar to HTML. PDF documents differ in that they are intended to appear the same whether on paper or on screen, regardless of the computer or printer involved PDF and HTML documents may both contain images. Unlike HTML documents, however, PDF documents may be highly compressed. Image files, such as those provided for by Portable Document Format (PDF) image files, do not presently provide “cut-and-paste” functionality for the overlying data. PDF documents may be either a “native PDF” file or a scanned image PDF file. Native PDF files are scannable and capable of being printed without the need for PostScript conversion. Native PDF are searchable and are of significantly smaller file size than scanned image PDF files (which must be printed through a PostScript conversion). Some agencies, such as the MSRB, allow native PDF or image PDF filings. 
     Other than by footnoting or keying in the source of the information, current electronic document data extraction methods do not provide means for collecting and managing the location lions which the data was originally sourced by an analyst. An electronic source document presented as an image file, native PDF, etc. must be manually transferred to the new document and manually referenced for cases of auditing. The ability to present an audit function or “click-thru” capability is unknown, particularly with respect to image files, non-structured text and html, and PDF documents. 
     Through the embodiments described herein, there is disclosed a method and system to capture click-thru data from the electronic media, such as documents for the collection, analysis and auditing of financial information. These methods and systems described are presently not available.

     DETAILED DESCRIPTION OF THE INVENTION 
     Disclosed in embodiments herein is a method and system allowing for a click-thru audit trail for information obtained from electronic documents, including non-structured total-based and non-html documents. Further disclosed in an embodiment is a system and method for built-in automation of the capturing, collecting, analyzing and auditing of financial data captured from electronic media, including image-based media. 
     Within an image document, such as a image-PDF file, and non-structured documents, such as non-structured HTML documents, there are elements which include text, images, and other objects related to the contents of the page. For example, a text element might include a word, a character, such as for example a number or letter, many words, or any combination of words and characters. An image electronic document, such as a Portable Document Format (PDF) file, and a non-structured HTML document is optimized for display purposes and not for the extraction of text 
     The program PDFTron allows for the indexing of elements recorded in a native PDF document by means of coordinate mapping a rectangular or semi-rectangular patch about the element. That is, the element is encompassed by a bounding box that defines its position on the page with respect to all other pixels comprising the page. The bounding box is the rectangle that encompasses the text and may be defined as the four points of an isolated subset of pixels mapping the vertices of the box. It comprises an x,y page coordinate for the bottom left corner, and an x′,y′ page coordinate for the top right corner of the rectangle. By such indexing, the position of an element comprising one or more characters can be found using a search function. 
     PDFTron is not configured to allow for trace mapping between different documents. A person, such as a financial, analyst, reviewing image electronic documents, or non-structured html/text documents, might only be interested in select portions of these documents, the combination of which may be used to generate a new document. While PDFTron would allow one to extract select information from each page of a native PDF and paste such information into a single document, the program is not configured for recording where the information was appropriated from other than by means of manual input of a note that may be added to the copied material. 
     In one exemplary embodiment, there is provided a system and method for allowing not only automated tracing of the origin of material comprising a document, but for allowing step-through of select individual elements recorded in a document to review the documents from which the select individual elements were extracted. 
     In such an embodiment, a directional pointer is determined for each page from which information is selected and imported into another document, and each of the elements on such page is delimited by a bounding box so as to generate a map of the element&#39;s position on the page (and its position with respect to other elements on the page). Such delimited elements are then extracted. Advantageously, the elements may further be parsed into characterize-sized pieces, each delimited by its own bounding box with the bounding box taking account into such parameters as font size and width of each character. The characters can then be sorted into a top to bottom, left to right, representation of all of the elements on the page from which they are extracted, forming an array matrix. The system may then group the characters into words and phrases, numbers etc., based upon recognition of the type of character involved. For example, a word may be defined as a set of alphabetic characters with minimal separation ‘space.” The ending of a word may be defined as either a ‘space’, the end of the line or where the next character may be considered sufficiently far away. Similarly, a phrase may be considered a set of words separated by single ‘spaces’ on, or nearly on, the same horizontal line. 
     By specifically providing for mapping of each character on a page, and from such mapped character automatically determining the elemental fundamental of which character is associated (e.g., such as a word or phrase), input of information into a secondary document can be greatly simplified, that is interaction with a character, such as clicking on the same, may be used to map and grab the elemental fundamental into the secondary document. For example, the x,y coordinate of a mouse over a character may be used to determine an appropriate bounding box of a fundamental element on that page. Thus, for example, if the mouse coordinate is found to be within one of the bounding boxes the character may be checked to determine whether it is a numeric and characters the left and right of the selected character may be examined to determine their numeric status, with additional characters on each side which are numeric being grouped together to form a elemental fundamental (i.e., a isolated numeric string). The elemental fundamental number string may be further surrounded by a rectangle and highlighted. As long as the mouse remains over a predetermined type of element, such as a numeric character the grouping may expand to include additional elements within proximity to the primary character indicated by the mouse coordinates. The entire elemental fundamental may then be exported to another document, such as a summary document. 
     Further to such example, the reviewer of the summary document may determine the path horn which an individual number string of the summary document, was extracted by highlighting the number string using, for example, a mouse (for example by double clicking on it). As the number string is associated with a particular source document pointer, as well as is mapped to said particular source document such that the position of the number string on such document may be highlighted or otherwise emphasized, the reviewer can quickly access the original source document and view where the information incorporated from the source document was obtained. Thus, there is provided click-thru capacity, allowing one to access in some cases multi-layers of source documents with respect to a particular input in the summary document. 
     Beyond mapping characters and fundamental elements associated with such characters, in an embodiment there is provide a system and method for associating a fundamental element with possible corresponding other elements, such as phrases related to a numeric figure (for example, those on the same horizontal line and built using the aforementioned process of creating the array can be examined and selected as a label for the numeric figure) The reviewer may, for example, indicate his/her choice of labels, for example by right-clicking on the previously highlighted rectangle of numbers. Labels from a menu of possible labels comprised of the left-most phrase on the line and the nearest phrase to the left may be presented to, and selected by the user. Default actions may be incorporated, for example, a default action may be to use the nearest, phrase to the left. The length of the phrase for a label may be limited by a predetermined value comprising the number of words or characters in the phrase. A number within a phrase, may use the phrase itself as the label. The length of the phrase may be predetermined in a fashion similar to that mentioned above. 
     In another embodiment, a page array as mentioned in a previous embodiment may be ordered in a top to bottom, left to right fashion for the purposes of recognizing and constructing a table. If the y coordinate of a bounding box within the page array is within a predetermined threshold value, it may be recognised that text associated with the bounding box is on the same horizontal line. As with some documents, such as Portable Document format (PDF) files, horizontal text may not exactly line up to a column/row format in its native state. 
     Recognition of columns within a table may be performed by examination of the line above and below the current text that has an overlapping bounding box in the horizontal direction. Analysis of the horizontal and vertical spacing can determine how to organize the phrases into table ‘cells’. The end of the table may be determined by whether the end of the page is reached or the encounter of a line that does not ‘fit’ in the columns as the rest of the text may. 
     In another embodiment, a user such as a financial analyst, may identify a table in an electronic document. The document, such as a Hyper-test Markup Language (HTML) document or Portable Document Format (PDF) file may contain columns to use as new values hi the continued analysis of the financial status of a company. Values from a table may also come from a page array similar to that mentioned in a previous embodiment. 
     Indication of interest in a table and/or column by the user, such as by clicking with a mouse button may cause parsing of the text and/or the recognition and/or creation of a table as mentioned in the previous embodiments. For example, a user may select the 2006 column of a given Income Statement to include as new values for a specific company&#39;s financial position. Prior year documents, having been previously entered are searched for similar labels. In another example, a previously collected value for the 2005 report may have had a label “Net Income”. A search through the current table for the same phrase “Net Income” may return a column to which the user is directed and where the new value may be selected. The data is automatically collected for the current document based on past information collected and analyzed. 
       FIG. 1  illustrates an exemplary embodiment of a capturing, collection, and analysis of electronic document system. The architecture of the system  5  may be composed of several layers comprising the input, processing and output of the system. The system of this embodiment may be called from within other windows implications supporting data collection. A document for Input  10  is read and sent to the appropriate document type processor  20  to  30  by the Initialization Layer  15 . The document may have an associated identification number (ID) and format which can be downloaded from a secure application program interlace, such as SECAPI. In addition to loading the document, the Initialization Layer  15  may provide the ability to integrate with other document providers. 
     The document processors  20  to  30  may comprise the document types of Portable Document Format (PDF), Text, and Hyper-text Markup Language (HTML). The document processor layer can open and read text from the document and identity and format tables of data within the document. In addition the document processors may extract table data such as rows, and columns along with the corresponding positional information for each, cell in the table. Document processors such as that used for Portable Document Format (PDF) isles  20  may send table information to the Processing Layer  35  after converting the table information to a standard format. The complexity of the processing layer may be reduced with the use of such a standard table format. Additional document type processors may be added to the system as needed. 
     The Processing Layer  35  of the system may identify the type of table, such as for example, a Balance Sheet an Income Statement, etc and apply the appropriate table rules to analyze the data. Rows and columns of the table can be identified and determined as to which rows should be merged to form a single row and which columns should be merged to form a single column, if rows or columns are merged, the click-thru information can be updated to reflect these changes. The Processing Layer  35  can also save the data in a format, such as a database, that will allow downstream applications to generate tables with click-thru information. 
     The Automatic Mapping Layer  40  reviews the history of data collected for the specific company being analyzed and/or audited and maps the data directly to the collection system. The mapping layer has the ability to learn over time based on the data collected and the selections made by the analyst reviewer. 
     Output  55  of the information from the system by the Presentation Layer  45  may be divided into two or more parts. Two potential divisions are for saving data and for displaying the document to the analyst reviewer. Saving data may include saving the table information such as the rows and columns in a database, and saving the mapping information into a database. The display portion may comprise the ability to display the entire document for collection, display extracted tables only with proper rows and columns, and display data mapped automatically in different colors based on the types of moping issues and/or the success rates. Within the Presentation Layer  45 , the Document Type API  50  may exist. The API can be used to assist with the presentation and interface with a calling program. 
       FIG. 2  is an exemplary screen shot of an embodiment of the system and methods. Screen shot  105  depicts two windows where data  110  from a Jun. 30, 2006 column of a company Balance Sheet is indicated of interest to the user. The data is selected and transferred to the second quarter (Q2) cell  115  of the alternate window for collection and analysis. 
     Turning to  FIG. 3 , an exemplary embodiment of the present invention is depicted. On screen  130 , data previously collected for MICROSOFT CORP (MSFT5949) is highlighted by display in an alternative color, such as blue. Individual numerical figures, such as Net Income to Common Shareholders  135  of $12,599.00 indicate that additional click-thru information is available if the client user wishes to drill down for more detail. If the client user selects one such figure, such as the Pretax Income  140  of $18,044.00 an additional screen  145  depicted in  FIG. 4  can be provided to show how the value was derived from the “as filed” values. Further click-thru on the “as filed” values may be performed. A client user may select a value, such as those on the first, click-thru screen  145  to link back to more source data. As illustrated in  FIG. 5 , such click-thru data may appear on an additional screen  150  where the source documents may highlight the item referenced. 
       FIG. 6  is a exemplary process flow diagram of an embodiment. System  160  may be comprised of three zones, internet  162 , processing  164  (shown as DMZ), and Internal storages areas  166 . Client user  170  (represented by a terminal) may send a request signal  172  to retrieve a document via SECAPI  176 , during which the document is transformed and a link is established  174 . An application interface Add-in  168  operatively communicates with Fundamentals Click-Thru Service Interface  186 . Further communication with Client User  170  and Fundamental Click-Thru Service interlace and SOAP/In-Process  186  may be accomplished by Strategic Fundamentals Pages  178 . Requests and responses  182  between Strategic Fundamentals Pages and Fundamental Click-Thru Service Interface and SOAP/In-Proc  186  operatively connect Client User  170  to additional functionality provided by the Fundamentals Click-Thru Services  184 . Information contained within the request signal may comprise symbol, year and ID information important to the user. The system may respond with information such as for example a SECAPI Document Return Universal Resource Locator (URL). Expressions Painter  180 , within the Strategic Fundamentals Pages can aide in request and response formulation. 
     Fundamentals Click-Thru Service  184 , containing Fundamental Click-Thru Service Interface  186  may communicate with process Construct SECAPI Doc Retrieval URL  188  and Construct Expression  190 . Signals  192  may be passed between the Fundamentals Click-Thru Service  184  and the Adaptive Layer  194  containing the application adapters, such as the Worldscope Adapter and the Extel Adapter. Information regarding the Client User  170  actions may ultimately be stored in SQL Server  196  storage, such as the Click-Thru Database, Worldscope Click-Thru Database, or the Extel Click-Thru. Database. The Strategic Fundamentals Pages  178  may communicate information, between the user  170  and an additional storage location  198 , such as a Worldscope Database. 
     In one exemplary embodiment, system  200  of  FIG. 7  may provide a Document Repository  205  from which information can be gained via a SECAPI  210  interface or a VAM prioritization process  215  to support various Analyst Reviewer terminals operating graphical user interfaces (GUIs)  220 . Information from the repository may be collected in a Master database structure  225  associated with the operating application, information may be allowed to flow from one sub-structure within the database to other sub-structures where the information may be formatted and standardized. Information from Collection Master database structure  225  can be passed to and stored at Calculation System  240  or to Content Click-Thru Master database structure  235 , a database structure separate and distinct iron) the application. Calculation information derived as a result of information obtained at Calculation System  240  may be deposited into Content Click-Thru Master database  235  information may be allowed to flow from one sub-structure within Content Click-Thru Master database structure  235  to other sub-structures. Sub-structures may comprise data as reported, mapping information, and formulas for calculation. Results of Calculation System  240  and information stored at Content Click-Thru Master database structure  235  can be passed to additional database structures  245  and  250  to support various products.
