     BACKGROUND OF THE INVENTION 
     The present invention relates to an apparatus, system, and method for predicting and accurately reproducing linguistic properties of character and word sequences using techniques involving affix data preparation, generation, and prediction. 
     Automated document preparation systems have been available for some time. These systems allow a plurality of individuals to dictate information to a transcription center where the dictated information is stored, transcribed and processed for distribution in accordance with a predetermined arrangement. Such systems are commonly employed in the healthcare industry where physicians, nurses and other medical professionals are required to maintain detailed records relating to the status of the many patients they see during the course of their daily routine. 
     As with virtually all industries, the healthcare industry in particular is beset by a need for readily available information. From physicians to patients the ready availability of information is somewhat limited when one looks to the availability of information in other fields. While much of the known scientific information relating to medicine is available via public and/or private databases, the manner in which the data is gathered and analyzed is very similar to methods which have been utilized since the development of the printing press. 
     That is, physicians typically conduct research on an individual basis and publish reports telling of the information they have found through their research. The basis for their research is, however, usually information of which they have first hand knowledge or information which has been previously published by other physicians. 
     In addition to the limited availability of information for use by physicians, the available information regarding the practice of medicine is stored and prepared in an arcane manner not readily understandable by the conventional patient. As such, medical patients are often forced to rely entirely upon information given to them by their personal physicians, and consequently overlook alternate procedures which may be preferable to those suggested by their personal physician. 
     Automated document preparation systems for some time have incorporated natural language processing to enhance document processing and information retrieval. For example, a natural language processor linked with a text normalization processor may be configured to compile relevant information related to reports generated by an automated document preparation system. The relevant information may be information related to diagnosis of diseases, treatment protocols, billing codes and the like. The relevant information may be compiled and indexed for later retrieval and research. 
     In the conventional natural language processors, morphological analysis and stemming techniques have been implemented to enhance natural language processing and information retrieval. Morphological analysis may include inflectional and derivational of natural language text. More particularly, inflectional analysis may involve determining patterns in paradigms and derivational analysis may involve the process of word formation. Computational methods applied to morphological analysis and generation in natural language parsing; text generation; machine translation; dictionary tools; text-to-speech and speech recognition; word processing; spelling checking; text input; information retrieval, summarization, and classification; and information extraction. 
     However, drawbacks and disadvantages are associated with the text processing engines. For example, the conventional information extraction engine is typically constructed using databases or tables of terms. In the medical fields, these tables often encompass several million of terms (words and phrases). The size of these tables not only encumbers computer memory resources, but also encumbers the performance of the normalization engine. More specifically, as the tables grow larger, the time required to search the tables grows larger. It would also be desirable to apply the same generation and prediction methods for a number of information extraction processing steps such as uninflection, underivation, and part-of-speech prediction; and for these methods to work equally well over words and phrases. The problem of processing text is burdened by the fact that it is not possible to list all possible terms. Consequently, prediction technology should not only provide precise information about the terms of which it has direct knowledge, but also be able to accurately predict information for novel or out-of-vocabulary terms. 
     Several shortcomings of the prior art that are addressed by the patent are: (a) enforcing the requirement that the prediction method is capable of perfectly rendering information supplied by the data set used to generate the predictor; (b) providing a method of excluding data from the generation process; (c) providing a method of incorporating exceptional data into the generation process; and, thereby, (d) providing the ability either to replace completely the original data set or to combine perfect rendition of the information in a data set and highly accurate prediction for novel or out-of-vocabulary terms. 
     SUMMARY OF THE INVENTION 
     One embodiment generally pertains to a method of prediction. The method includes generating an ordered set of affixes from a selected input sequence and comparing the set of affixes with a stored set of affixes. The method also includes selecting an affix from the stored set of affixes used for prediction; and retrieving the prediction associated with that affix. In the following presentation, the term “affix” is used to refer to suffixes (trailing sequences), prefixes (leading sequences), and infixes (interior sequences) and their combinations. 
     Another embodiment generally relates to a method for generating a data set. The method includes receiving a corpus (organized set of texts) and generating a set of data triplets based on the corpus. Each triplet consists of an affix, an associated pattern, and a frequency of occurrence for the affix and associated pattern. The method also includes selecting a subset of triplets as the data set, where a selection criteria is based on length and frequency of occurrence. 
     Yet another embodiment generally relates to a system for predicting a pattern using affixes. The system includes an affix prediction module, an affix prediction data set, and an affix generation module. The affix prediction module is configured to retrieve terms based on matching affixes generated from an input sequence with entries in the affix prediction data set generated by the affix generation module. 
     Yet another embodiment generally pertains to an apparatus for generating a data set. The apparatus includes means for receiving a corpus comprising of a plurality of sequences and means for generating a set of triplets based on the corpus. Each triplet has an affix, an associated pattern, and a frequency of occurrence for the affix and associated pattern. The apparatus also includes means for selecting a subset of triplets as the data set, where a selection criteria is based on length and frequency of occurrence.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The present disclosure will now be described more fully with reference the to the Figures in which an embodiment of the present disclosure is shown. The subject matter of this disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. 
       FIG. 1  illustrates a block diagram of an affix prediction module  100  in accordance with an embodiment of the present invention. It should be readily apparent to those of ordinary skill in the art that the affix prediction module  100  depicted in  FIG. 1  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. Moreover, the affix prediction module  100  may be implemented using software components, hardware components, or a combination thereof. 
     As shown in  FIG. 1 , the affix prediction module  100  includes a prediction module  110 , an affix generation module  120 , and a storage module  130 . The prediction module  110  may be configured to make predictions based on a sequence of letters, words, tokens, etc. This sequence, i.e., affix, may consist of a combination of prefix, infix, and suffix sequences drawn from the input sequence. The prediction module  110  may utilize an affix prediction data set, stored on the storage module  130 . More particularly, the prediction module  110  may process input sequences from an input file in one embodiment. In other embodiments, the input sequences may be provided over a network. 
     The prediction module  110  may generate all possible affixes for the selected input sequence. The prediction module  110  may compare the generated affixes with affixes stored in the affix prediction data set, which is may be stored on the storage module  130 . When the prediction module  110  determines a match between the longest affix of the input sequence with an affix in the affix prediction data set, the prediction module  110  retrieves the pattern and/or action associated with the matching affix. In one embodiment, the affix may represent an electronic mail address and the action may initiate the loading of an electronic mail client with the affix. 
     The affix generation module  120  may be configured to generate three data sets: a master data set, an excluded data set, and an add-in data set. Each data set comprises of entries of triplets. A triplet consists of an affix form, i.e., an ordered sequence of characters or words, a pattern, i.e., an attribute, property, or action associated with the associated affix form, and a frequency, which is derived or estimated frequency of occurrence of the form-pattern combination. 
     The master data set is configured to provide a basis for pattern generation, which is used to generate the affix prediction data set. The excluded data set is configured to provide a subset of triplets from the master data set that are not intended to undergo pattern generation. The excluded data set may be utilized under some circumstances to ensure that irrelevant affixes are not generated for non-productive data types. For example, a closed set of function words (prepositions, conjunctions, pronouns, article, and so forth) in a natural language may be excluded from the generation of part-of-speech prediction patterns for content words (nouns, verbs, adjectives, and adverbs). The add-in data set is configured to contain a set of triplets that are added “as-is” to the affix prediction data set. The add-in data set is used to incorporate exceptions into the affix prediction data set. In certain embodiments, the affix prediction data set may be generated based on the master data set alone or in combination with the excluded data set or add-in data set. The actual combination of data set may depend on the requirements of a particular application for the natural language processor. 
     The affix generation module  120  may be configured to receive the master data set, i.e., a corpus of organized set of texts, a vocabulary or lexicon, or other similar input, to generate the affix prediction data set. The affix generation module  120  may also be configured to receive a set of parameters, e.g., the length of the longest affix, lowest frequency affix-pattern combination, etc., associated with the predicted affix set. The affix generation module  120  may pre-process the master data set by pre-pending and/or post-pending each term in the master data set with a distinctive peripheral symbol (the symbol being different from any possible character or word) to identify the beginning and the end of a sequence. 
     The affix generation module  120  may be further configured to generate triplets for the characters and/or words of on the master data set and, optionally, the application of either the excluded data set or the add-in data set or both. More particularly, the affix generation module  120  may generate sequences of characters in a predefined order, i.e., an affix, from the characters and/or words of the master data set. For each sequence, the affix generation module  120  may determine an associated pattern of the affixes, and the frequency of the affix-pattern combination. In one embodiment, the affix generation process may incorporate a shortest pattern consisting of the distinctive peripheral symbol for each member of the corpus. The default prediction (i.e., when no non-empty affix matches) is provided by this special affix. In other embodiments, the affix generation module  120  may eliminate an affix-combination pattern if it is longer than the pre-determined longest affix. 
     The affix generation module may be further configured to maintain the frequency of each affix-pattern combination by keeping a count of the frequency of each affix-pattern combination and adding to the count for every new instance of that affix-pattern combination. In further embodiments, the affix generation module may eliminate affix-pattern combinations for those combinations, which fall below the predetermined lower frequency pattern combination. 
     The affix generation module  120  may yet be further configured to select a subset of the generated triplets. More particularly, the affix generation module  120  may sort all triplets based on length of affix, the frequency, i.e., from shortest to longest affix and from lowest to highest frequency. The affix generation module  120  may then start from the shortest affix to determine the highest frequency of an affix-pattern combination for a given affix. The shortest affix with the high frequency is entered into the affix prediction data set. The affix generation module  120  may also determine that a most frequent affix-pattern combination for a selected affix has the same prediction as an affix that is contained within another shorter affix, the selected affix is then eliminated. 
       FIG. 2  illustrates a natural language patient record (NLPR) system  200  utilizing the affix prediction module in accordance with yet another embodiment. It should be readily apparent to those of ordinary skill in the art that the system  200  depicted in  FIG. 2  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. Moreover, the system  200  may be implemented using software components, hardware components, or a combination thereof. 
     As shown in  FIG. 2 , the NLPR system  200  includes a plurality of workstations  205  interconnected by a network  210 . The NLPR system  200  also includes a server  215  executing a computer readable version  220  of the NLPR system and data storage  225 . The NLPR system  200  is a system for maintaining electronic medical records of patients, which is described in greater detail in co-pending U.S. patent application Ser. No. 10/447,290, entitled, “SYSTEM AND METHOD FOR UTILIZING NATURAL LANGUAGE PATIENT RECORDS,” filed May 29, 2003, which has been incorporated by reference in its entirety. 
     The workstations  205  may be personal computers, laptops, or other similar computing element. The workstations  205  execute a physician workstation (PWS) client  230  from the NLPR system  200 . The PWS client  225  provides the capability for a physician to dictate, review, and/or edit medical records in the NLPR system  200 . While  FIG. 2  is described in the realm of the medical field, it will be understood by those skilled in the art that the present invention can be applied to other fields of endeavor where users dictate, review and edit records in any domain. 
     The workstations  205  also execute a transcriptionist client  235  for a transcriptionist to access and convert audio files into electronic text. The NLPR system  200  may also use speech recognition engines to automatically convert dictations from dictators into electronic text. 
     The network  210  is configured to provide a communication channel between the workstations  205  and the server  215 . The network  210  may be a wide area network, local area network or combination thereof. The network  210  may implement wired protocols (e.g., TCP/IP, X.25, IEEE802.3, IEEE802.5, etc.), wireless protocols (e.g., IEEE802.11, CDPD, etc.) or combination thereof. 
     The server  215  may be a computing device capable of providing services to the workstations  205 . The server  215  may be implemented using any commonly known computing platform. The server  215  is configured to execute a computer readable version of the NLPR software  220 . The NLPR software provides functionality for the NLPR system  200 . The NLPR system  200  may receive audio files and/or documents by other network access means such as electronic mail, file transfer protocols, and other network transferring protocols. 
     The data storage  225  may be configured to interface with network  210  and provide storage services to the workstations  205  and the server  215 . The data storage  225  may also be configured to store a variety of files such as audio, documents, and/or templates. In some embodiments, the data storage  225  includes a file manager (not shown) that provides services to manage and access the files stored therein. The data storage  225  may be implemented as a network-attached storage or through an interface through the server  215 . 
       FIG. 3  illustrates a flow diagram of loading predictive data  300  executed by the prediction module  120  according to one embodiment of the present invention. It should be readily apparent to those of ordinary skill in the art that this flow diagram  300  represents a generalized illustration and that other steps may be added or existing steps may be removed or modified. 
     As shown in  FIG. 3 , when invoked the prediction module  110  may retrieve a predictive data set of affixes  310  from the storage module  130 . In the NLPR system, the predictive data set of affixes is loaded during NLPR system initialization. In other embodiments, the prediction module  110  may access the predictive data set  310  from a remote database, server or other similar persistent memory device. 
     In yet other embodiments, the predictive data set of affixes  310  may be tailored to a specific application. More specifically, the affix prediction module  100  may utilize a predictive data set of affixes  310  generated based on a legal lexicon for legal applications. Similarly, the affix prediction module  100  may be specifically tailored for specialties within a field. For example, predictive data set of affixes may be generated for oncology applications, gynecology applications, internal medicine applications, infectious diseases, etc. Accordingly, the affix prediction module  100  may be programmed to a specialty based on selecting the appropriate predictive data set. 
       FIG. 4  illustrates a flow diagram of matching input data  400  implemented by the prediction module  110  according to one embodiment of the present invention. It should be readily apparent to those of ordinary skill in the art that this flow diagram  400  represents a generalized illustration and that other steps may be added or existing steps may be removed or modified. 
     As shown in  FIG. 4 , the prediction module  110  may be configured to receive an input sequence from an input file, in step  405 . The prediction module  110 , in step  410 , may be configured to determine whether or not the last input sequence from the input file has been processed. For example, the prediction module may determine if an end-of-file character has been reached. 
     If the prediction module  110  determines that the end of input sequences has been reached, the prediction module  110  may terminate processing, in step  415 . Although not explicitly shown, the prediction module  110  may return control to a calling program. 
     Otherwise, if the prediction module  110  determines that an input sequence has been retrieved for processing, the prediction module  110  may be configured to generate all possible affixes for the received input sequence, in step  420 . The affix generation process done during prediction is identical to the process applied during the affix prediction data base generation phase. In an inflection prediction application, the affix generation (resp. recognition) process might consist of generating all possible suffixes of a given input term. For example, given the term “#diabetes#” (where ‘#’ is the peripheral symbol), the affix generation (resp. recognition) process might generate the set of suffixes, from right-to-left of the input term: {#, #s, #se, #set, #sete, #seteb, #seteba, #setebai, #setebaid, #setebaid#}. In another embodiment, the affix generation (resp. recognition) process might incorporate prefixes or suffixes of the input term. 
     In step  425 , the prediction module  110  may compare the generated affixes with the entries in the predictive data set  310 . More specifically, the prediction module  110  may match the longest affix of the received input sequence with the predictive data set  110 . A match is guaranteed since all sequences must contain peripheral symbols. In step  430 , the prediction module  110  may retrieve the associated pattern/action associated with the longest match. In step  435 , the retrieved pattern/action is returned to the calling program for further processing. Subsequently, the prediction module  110  retrieves the next input sequence from the input file in step  405 . 
       FIG. 5  illustrates a diagram of data sets  500  involved in generating the affix prediction data set  305  by the affix generation module  120  (shown in  FIG. 1 ) according to one embodiment of the present invention. In certain embodiments, a master data set  510 , an excluded data set  520 , and an add-in data set may be used to generate the affix prediction data set  305 . Each of the data sets comprises of triplets. A triplet comprises an affix sequence, a pattern associated with the affix sequence, and a frequency associated the affix sequence-pattern combination. 
     The master data set  510  may be configured to provide a basis for pattern generation. The excluded data set  520  may comprises a subset of triplets that are excluded from the master data set  510  that are not intended to undergo affix pattern generation. The add-in data set  530  may be configured to provide a set of triplets that are added “as-is” to the affix prediction data set  305 . 
     The excluded data set  520  and the add-in data set  530  may be included at the option of the end-user or as a function of the application of the affix prediction module  100 . More particularly, a master data set of word inflections may contain a large number of irregular inflections (e.g., run, runs, running, ran). In natural languages, irregular inflections are not productive, i.e., their patterning is not used, for example, in creating inflections of new words, and thereby may qualify to be included in the excluded data set. However, the irregular inflections would be included in the add-in data set to ensure that irregular inflections are found in the affix prediction data set. 
       FIG. 6  illustrates a flow diagram for the generation of the affix prediction data set  305  implemented by the affix generation module  120  according to another embodiment of the invention. It should be readily apparent to those of ordinary skill in the art that this flow diagram  600  represents a generalized illustration and that other steps may be added or existing steps may be removed or modified. 
     As shown in  FIG. 6 , the affix generation module  120  may be configured to receive the master data set  510  and the excluded data set  520  and remove the triplets of the excluded data set  520  from the master data set  510 , in step  605 . In other embodiments, the excluded data set  520  may not be processed to filter entries in the master data set  510 . The inclusion of the excluded data set may be an end-user&#39;s discretion. 
     In step  610 , the affix generation module  120  may be configured to generate the minimal affix patterns associated with each triplet in the excluded or filtered master data set to generate a temporary predictive data set  615 .  FIG. 7  illustrates in greater detail the generation of the minimal affix patterns, as described herein below. 
     In step  620 , the affix generation module  120  may be configured to add the add-in data set  530  to the temporary predictive data set  615  to created the final predictive affix patterns as the prediction data set  310 . In yet other embodiments, the add-in data set  520  may not be processed. The processing of the add-in data set  520  may be an end-user option. 
       FIG. 7  illustrates a flow diagram  700  of the generation of the minimal affix patterns (shown in  FIG. 6 ) as implemented by the affix generation module  120  according to yet another embodiment of the invention. It should be readily apparent to those of ordinary skill in the art that this flow diagram  700  represents a generalized illustration and that other steps may be added or existing steps may be removed or modified. 
     As shown in  FIG. 7 , the affix generation module  120  may be configured to set parameters, in step  705 . More specifically, the affix generation module  120  may set threshold values for parameters such as length of the longest affix, lowest frequency affix-pattern combination allowed, and so forth. In certain embodiments, the affix generation module  120  may generate a graphical user interface for a user to set the threshold values. 
     In step  710 , the affix generation module  120  may be configured to implement a sequence preparation on the filtered master data set. More particularly, the affix generation module  120  may pre-pend and/or post pend each term with a distinctive peripheral character or word to identify the beginning or end of a sequence. 
     In step  715 , the affix generation module  120  may be configured to generate triplets for the characters and/or words of the corpus. More particularly, the affix generation module  120  may generate sequences of characters in a predefined order, i.e., an affix, from the characters and/or words of the corpus. For each sequence, the affix generation module  120  determines an associated pattern of the affixes, and the frequency of the affix-pattern combination. In other embodiments, the affix generation module  120  may eliminate an affix-combination pattern if it is longer than the pre-determined longest affix. 
     In step  720 , the affix generation module  120  may be configured to maintain the frequency of each affix-pattern combination by keeping a count of the frequency of each affix-pattern combination and adding to the count for every new instance of that affix-pattern combination. In further embodiments, the affix generation module  120  may eliminate affix-pattern combinations for those combinations, which fall below the predetermined lower frequency pattern combination. 
     In step  725 , the affix generation module  120  may select a subset of the generated triplets. More particularly, the affix generation module  120  may sort all triplets based on length of affix, the frequency, i.e., from shortest to longest affix and from lowest to highest frequency. The affix generation module  120  may then start from the shortest affix to determine the highest frequency of an affix-pattern combination for a given affix. The shortest affix with the high frequency is entered into the affix prediction data set. The affix generation module  120  may also determine that a most frequent affix-pattern combination for a selected affix has the same prediction as an affix that is contained within a shorter affix, but there are not affixes intervening between this shorter affix and the given affix with a different pattern, the selected affix is then eliminated. 
       FIG. 8  illustrates an exemplary block diagram of a computer system  1000  where an embodiment may be practiced. The functions of the affix prediction module  100  may be implemented in program code and executed by the computer system  800 . The affix prediction module  100  may be implemented in computer languages such as PASCAL, C, C++, JAVA, and so forth. 
     As shown in  FIG. 8 , the computer system  800  includes one or more processors, such as processor  802 , that provide an execution platform for embodiments of the affix prediction module. Commands and data from the processor  802  are communicated over a communication bus  804 . The computer system  800  also includes a main memory  806 , such as a Random Access Memory (RAM), where the software for the affix prediction module  80  may be executed during runtime, and a secondary memory  808 . The secondary memory  808  includes, for example, a hard disk drive  820  and/or a removable storage drive  822 , representing a floppy diskette drive, a magnetic tape drive, a compact disk drive, or other removable and recordable media, where a copy of a computer program embodiment for the affix prediction module  100  may be stored. The removable storage drive  822  reads from and/or writes to a removable storage unit  824  in a well-known manner. A user interfaces with the affix prediction module  100  with a keyboard  826 , a mouse  828 , and a display  820 . The display adaptor  822  interfaces with the communication bus  804  and the display  820  and receives display data from the processor  802  and converts the display data into display commands for the display  820 . 
     Certain embodiments may be performed as a computer program. The computer program may exist in a variety of forms both active and inactive. For example, the computer program can exist as software program(s) comprised of program instructions in source code, object code, executable code or other formats; firmware program(s); or other known program. Any of the above can be embodied on a computer readable medium, which include storage devices and signals, in compressed or uncompressed form. Exemplary computer readable storage devices include conventional computer system RAM (random access memory), ROM (read-only memory), EPROM (erasable, programmable ROM), EEPROM (electrically erasable, programmable ROM), and magnetic or optical disks or tapes. Exemplary computer readable signals, whether modulated using a carrier or not, are signals that a computer system hosting or running the present invention can be configured to access, including signals arriving from the Internet or other networks. Concrete examples of the foregoing include distribution of executable software program(s) of the computer program on a CD-ROM or via Internet download. In a sense, the Internet itself, as an abstract entity, is a computer readable medium. The same is true of computer networks in general. 
     It will be apparent to one of skill in the art that described herein is a novel system and method for predicting and accurately reproducing linguistic properties of character and word sequences using techniques involving affix data preparation, generation, and prediction. While the invention has been described with reference to specific preferred embodiments, it is not limited to these embodiments. The invention may be modified or varied in many ways and such modifications and variations as would be obvious to one of skill in the art are within the scope and spirit of the invention and are included within the scope of the following claims.
