COMMUNICATION SYSTEM WITH TEXT MESSAGE RETRIEVAL BASED ON CONCEPTS INPUTTED VIA KEYBOARD ICONS

Abstract: A Natural Language Processing System utilizes a symbol parsing layer (5) and an intelligent word parsing layer (5) to produce a syntactically or pragmatically correct output. A plurality of polysemic symbol sequences are input through a keyboard with semantic, syntactic, or pragmatic segments including agent, action and patient segments, for example. One polysemic sequence is input from each of the three segments of the keyboard (1). A symbol parsing device, then parses each symbols in each polysemic symbol sequence to access a previously stored word, morpheme, or phrase. The accessed word, morpheme, or phrase (50) corresponds to the input polysemic symbol sequence and further corresponds to one of the designated agent, action or patient segments. Each accessed word, morpheme, or phrase further accesses corresponding and previously stored grammatical and semantic information. An intelligent word parsing layer (5) subsequently applies each of the plurality of words, morphemes, or phrases to a predetermined hierarchy of rules based upon the accessed grammatical and semantic information. The intelligent word parsing device subsequently parses the received plurality of accessed words, morphemes, or phrases into a syntactically or pragmatically correct output.

Description: COMMUNICATION SYSTEM WITH TEXT MESSAGE RETRIEVAL BASED ON CONCEPTS INPUTTED VIA KEYBOARD ICONS BACKGROUND OF THE INVENTION The present invention relates to a natural language processing system in general, and more particularly relates to a system for initially parsing a plurality of symbols and subsequently parsing a plurality of words, morphemes, or phrases to produce a syntactically or pragmatically correct output sentence. A system and method for producing synthetic plural word messages for use by people unable to use their own voices is known in the speech synthesizing arts. The system was originally implemented as a linguistic coding system with an associated keyboard, in which the coding system was based on a symbol rather than a word, phoneme or letter. Such a system is disclosed in United States Patent No. 4,661,916 to Baker et al issued April 28, 1987. In such a system, the keyboard is coupled to a computer which stores a plurality of plural word messages in a memory thereof for selective retrieval by the keyboard. The plural word messages retrieved by t keyboard are fed to a voice synthesizer which conver them through a loudspeaker to achieve audible message The keyboard utilizes polysemic (many-meaning) symbols icons on the respective keys and by designating one more of the keys and its associated polysemic symbol selected previously recorded plural word messages from t computer memory may be. retrieved in a simple transducti manner. The messages in memory are retrieved by actuati a particular sequence of a plurality of keys, to vary t context of the polysemic symbols. Thus, a plurality sentences associated with each key in a particul sequence with a plurality of other keys may be selective generated as a function of each polysemic symbol combination with other symbols to access the plural wo message or sentence. Since such a communication aid is designed to adaptable to either people of high intellect and educati who are physically unable to speak or people wi decreased cognitive abilities or little education, system which is both easy to understand and operate, well as quick and efficient, is necessary. Further, it essential that both the cognitive and physical loa required by the user are reduced as much as possibl However, systems, other than Baker '916 for synthet speech, or typing devices, which have coding systems bas on words, phonemes, or letters to be implemented keyboards with indicia thereon relating to the word phonemes, or letters are somewhat limited in efficiency operation. In utilizing a system based upon letters, f example, a limited number of keys could be utilized (i.e 26 letters in the alphabet). However, such a system utilizing letters has several drawbacks. One drawback is that in a system for people physically unable to speak or who are cognitively impaired, spelling is difficult to master. People who can't articulate the sounds of a language have a limited ability to deal with letters. Finally, in utilizing letters one must type a large number of letters in a sequence to form a word, phrase and especially a sentence. Such a large number of keystrokes is especially cumbersome for someone with decreased cognitive or physical abilities. In order to combat the problem of the need for a large number of letters in a sequence, single meaning picture or symbol approaches have been developed. In these systems, a symbol or picture can be utilized to represent a single basic concept or word. Because these systems are based upon single concepts or words and not letters, only a few symbols need be utilized, in sequence to represent a phrase or sentence. However, the major drawback of these systems is different from letter based systems. Although only a few symbols are necessary to form a sequence, many hundreds of symbols could be necessary to represent enough vocabulary to interact at home, at school or in the workplace. Thus, hundreds and even thousands of symbols could be necessary for a user to choose from. These large symbol sets are not only physically difficult (if not impossible) to represent on a keyboard, but also put a severe strain on the cognitive and physical abilities of a user both to choose a symbol from the large symbol set and further to key in the selected symbol. Various techniques have been developed in attempt to deal with the deficiencies of either the n for a large number of letters to form a sentence in letter-based system; or the need for a large symbol to represent all the notions or vocabulary necessary f daily interactions in a single-meaning picture/sym system. One approach aimed at combating the l sequences of letters necessary in a letter system is use alphabetic abbreviations. With such systems a us was unsure as to what each abbreviation stood for, f example, (wk) could stand for "walk" and (wo) could sta for "word", but what would stand for "work". The us could become confused and think either (wk) or (wo) sto for "work" . Another attempt to alleviate the large number keystrokes needed in spelling was word/letter predicti systems. In such systems, a user would type a letter su as "B" and five words starting with "B" would appear on display. Upon not finding the desired word displayed, operator would then hit the next letter "0" of the desir word (if the desired word were "Bottle" for example) . the desired word is then displayed on the word list t number next to the desired word is noted and then hi Such systems are highly visual requiring attenti directed at two different fields, the keyboard and t screen. And these systems require operators to ha strong spelling abilities (if he hit the wrong letter su as a "C" when the word "kitten" was desired, predicti would start with five words beginning with "C" and t user would be lost) and further, it was cognitive disorienting because it required the user to key a lette read word lists on a display, key in another lette select a number, etc. Levels/locations systems were developed in an attempt to alleviate the large symbol set of single meaning picture/symbol systems. In such systems, a plurality of keyboard overlays were utilized. Each overlay contained a plurality of single-meaning pictures or symbols for a particular activity. For example, there was a "party" overlay, a "going to the zoo" overlay, an A.M. activities overlay, etc. However, although only a limited number of symbols were on a keyboard at one time, the system severely limited a user's vocabulary at all times. For example, if there were 7 overlays, when a user had one on the keyboard, 85% of his vocabulary was unavailable to him, it being on the other six overlays. Thus, the abilities of a user were severely limited. The linguistic coding system of Baker et al, United States Patent No. 4,661,916, thereby solved a great number of these problems by employing a technique called semantic compaction. Semantic compaction utilized a keyboard with polysemic (many-meaning) symbols or icons on the respective keys. These polysemic symbols allowed for a small symbol set (each symbol having many different meanings depending upon other symbols in combination) and further allowed for utilization of only a small number of symbols in a sequence to transduce a previously stored word, phrase, or sentence. An example of the polysemic symbols of the Baker '916 patent are shown in Figure 1. Thus by input of only a limited number of polysemic keys, a sentence or other plural word message can be selectively retrieved. The sentence can then be sent to a voice synthesizer to convert it, through a loudspeaker, to an audible spoken message. This device is a synthetic speech device which allows a user to go directly from thought to speech without the need to record words, phonemes letter data of individual entities. The Baker device retrieves and stores wh sentences and plural word messages for select retrieval, and not just individual words, phonemes, letters. By using these polysemic symbols, combination, only a small number of key actuations necessary to represent a sentence or plural word messag These iconic polysemic symbols or "icons" for short, they are more commonly known, on the individual keys, we made so as to correspond to pictorial illustrations real life objects, as can be seen by reference to Figu 1. These icons were utilized because such symbols w more easily memorized and more versatile t alpha-numeric characters. Therefore, a user of l intellect, or one with a disability, would easily be a to access these icons representing real life objects thus access plural word messages and thereby have the messages synthesized for output speech. Large repertories of words, sentences and phras were available and used by operators with a wide range physical and cognitive disabilities. Many operato handled repertories in excess of 3000 vocabulary units. However, although the system of Baker et al '9 is a revolutionary breakthrough in augmentative a alternative communication (AAC), there is still room f improvement over an iconic system utilized which produc synthetic word messages. The system of Baker '91 utilizes a simple transduction algorithm wherein plurality of plural word messages or sentences a initially stored in a memory corresponding to a particul sequence of icons. Upon the user activating that particular sequence of icons, the corresponding plural word message or sentence are directly accessed from memory, sent to a voice synthesizer, and converted through a loudspeaker to achieve audible spoken messages. However, as previously mentioned, such a system merely utilizes simple transduction of a previously stored word message, that is words, phrases or sentences accessed via a particular sequence of polysemic symbols or icons. The use of symbol parsing techology in Baker '916 was a revolutionary breakthrough but was limited to this simple transduction model. Although a finite-state transducer is easy to program into a small microchip, it is also inflexible and cannot anticipate the user's intentions the way a more intelligent parsing technology can. A system is desired in which users can have the greater freedom of icon selection, not having to worry about the precise ordering or completeness of an icon sequence, as well as a system having even fewer key actuations than a system such as Baker '916. Such a system, reducing the requirements of the user as well as reducing the number of necessary icons, can be achieved through intelligent parsing. A further reduction in the number of selections and the field of selections that such intelligent parsing can produce may be a substantial aid not only to those individuals who are cognitively intact and have intact language, but also to individuals who are cognitively impaired or have serious language deficiencies. A natural language processing system is desired which further reduces both the cognitive and physical loads on the user. If the user is required to remember not only what concepts each icon represents, but also how to assign grammatical functions, morphologic inflections, etc., then a smaller number of users will successful. This is particularly true for potenti system operators who have had strokes or experienc congenital, cognitive impairments. However, if the syst can anticipate what is intended (for example, inferri that an action should be uttered as a particul inflection of a verb by taking into account subject-ve agreement) then the cognitive load of the user is reduce since less information must be remembered and conveyed complete an utterance. In reducing the physical load, the number of ke can be reduced by eliminating entire classes of keys (li those that inflect verbs and verb tense) since fewer k actuations will be required. A reduction in k actuations greatly improves the quality of the user interaction, especially for users with limit capabilities. It it desired to combine parsing technology wi interface technology to produce a successful devic These two technologies must be in balance so that t user's expectations are not violated. If the user presented with an elegant interface that has litt functionality behind it, he will become quick disillusioned. Consequently, if the user is present with a device that has an inadequate interface a excellent functionality, he will rapidly beco frustrated. It is an unfortunate downfall of ma computer systems in present technology that rely too mu on fancy graphics to make up for a lack of re capability. The existing linguistic coding system Baker et al '916, has an excellent balance between accessibility and functionality which should be preserved. It is further preferred to design a system which uses particular semantic relationships among polysemic icons (multi-meaning symbols or pictographs) to assign a meaning to a sequence of key actuations made by a user. A sequence of icons may be associated with a particular language item, such as a morpheme, word, phrase or plurality of words, to be output when that particular icon sequence is actuated. Icons can be utilized to access language items and thus do what letters, single meaning pictures, words, and numbers cannot. Clearly, there are certain associations that can be made with both an icon and the word representing that icon. For example, it is easy to make the association with the word "food" when presented with either a picture of an apple or the word "APPLE". However, it is clear that there are certain kinds of association that can be made consistently and unambiguously with icons, although certain exceptions may hold. For example, the greatest advantage that icons have over numbers, letters and words, is that, as pictographs, they each have distinct visual features that can be made easily transparent (translucent) to the user. For example, each icon has a shape, and a color, and picture some object which may have other visual properties as well. Although some symbols have shapes which are readily accessed (for example, 0, I, X, A), the abstract shapes of symbols are not unambiguous; the more abstract an association, the greater the chance the user will not prefer the intended interpretation. For example, "A" can be associated with a house or a mountain or a tall building, the tip of a pencil, etc. Since the shape "A" is so abstract, many associations are possible. icon of "house", however, is not subject to the s ambiguity. Some systems have attempted to use letter cod to associate letters with concepts; however, this met of encoding is also prey to ambiguous interpretation. example, a reasonable letter coding for the color "R would be the letter "R"; for "BLUE", the coding would "B". However, what happens with the color "BROWN"? logical choice would also be "B", but a conflict ari with the code chosen for "BLUE". The same problem ari as in the previous example; since there are litera thousands of words which can be associated with a sin letter, a letter-coded system rapidly runs out of cod space and is therefore limited in the number of conce it can encode unambiguously. Letter codes can be done in various ways. Two the most common ways to encode plural word messages called "salient letter encoding" and "semantic encodin Salient letter encoding takes the initial letter of two more fundamental words in the language string to represented and uses them for the code. For examp "Turn the radio off" can be encoded as "RO" using t method. The problem arises that after many utteranc the same letters "RO" are needed to represent ot language strings. For instance, "RO" are the most sali letters for "Turn the radio on" . A strategy must then employed to find other salient letters so that ambiguity is avoided. Hence, "Turn the radio on" must encoded using a different code such as "TO" or "T However, these letter combinations in turn can repres other common phrases such as "Take it off" or "Turn right". As the language corpus grows larger, the task of finding other unique combinations of salient letters becomes more and more difficult and by necessity must include codes that are less and less salient and more difficult to learn. After 500-1000 units are encoded, the codes become virtually arbitrary. Semantic encoding takes letters to associate with concepts rather than individual words, so that "F" can be taken to represent food. The plural word message "I would like a hamburger" would then be encoded by "FH". The difficulty here is that "F" can represent many different concepts and must be used not only for "food" but for concepts such as "fast", "friends", etc. If each letter is assigned a single concept, a language corpus represented by the combinations of twenty-six root concepts would indeed be impoverished. If letters are allowed to represent one concept in initializing a sequence, and other concepts as second or third members of a sequence, this disambiguating what concept a letter means across a string of three letters becomes a difficult if not impossible task once the language corpus has grown to five hundred units or more. A system is necessary which incorporates ideas from research and knowledge representation and natural language processing. The goal of knowledge representation research is representing an acquired knowledge from everyday domains (e.g., task planning, language understanding) that can be used by intelligent computer programs. The goal of natural language processing research is to investigate in particular the knowledge that is required for a computer program to understand and produce sentences in English or some other natu language. It can be said that the intelligence of a sys is determined by how much it knows. Before a computer show an understanding of a linguistically comp utterance, it must have a significant body of knowle about morphology, word meaning, syntax, etc. In order support intelligent processing, much linguistic knowle must be incorporated into the system. The system may not only combine the sym parsing of multi-meaning sequence icons along w intelligent word parsing, but further utilize well-chosen geographic layout which can provide the sys with syntactic and semantic information based on locations of the icons which are selected. This theref reduces knowledge and inferencing required by intelligent word parser. SUMMARY OF THE INVENTION The present invention is directed to a natu language processing system for initially parsing each o plurality of sequences of input polysemic symbols, ea sequence including a plurality of input polysemic symbol to produce a word, phrase, or morpheme, and subsequent parsing each of the single morphemes, words, or phras into a syntactically or pragmatically correct word messa output. The system includes an input device, segment into a plurality of syntactic, semantic, or pragmat segments, each such segment including a plurality keys. Each key includes one of the plurality of polysemic symbols. Upon actuation of an input key, a particular polysemic symbol is accessed and further syntactic, semantic or pragmatic segment information designating each corresponding polysemic symbol as one of an agent, action and patient, for example, is entered into the system. A symbol parsing layer is then included for parsing a plurality of sequentially accessed polysemic symbols inito a plurality input symbol sequences. The symbol parsing layer then accesses each of the phrases, words, or morphemes previously stored with a symbol sequence, corresponding to each of the input symbol sequences and further corresponding to one of the designated syntactic, semantic, or pragmatic segments. Each accessed word, phrase, or morpheme further accesses corresponding, and previously stored, grammatical and semantic information. Finally, an intelligent word parsing layer receives and subsequently applies each of the plurality of accessed words, phrases, or morphemes to a predetermined set of rules and, based upon the corresponding grammatical and semantical information, parses the received plurality of accessed words, phrases, or morphemes into a syntactically or pragmatically correct output sentence or other word message. The terms "syntactic," "semantic" and "pragmatic" information used throughout this description are all encompassed by the generic term "linguistic knowledge." It should also be understood that the terms "syntactic" and "semantic" information are encompassed by the generic term "grammatical" information. Therefore, in the following description and appended claims the relations of these terms should be clear in the context of present invention. It is therefore an object of the pres invention to employ a system utilizing an input devi containing a plurality of multi-meaning icons, which arranged in a well-chosen geographic layout such t actuation of a particular key can provide the system w syntactic, semantic, or pragmatic information based on location of an icon selected, thus reducing knowledge inferencing required by a subsequent intelligent w parser. It is another object of the present invention employ a symbol parsing layer in combination with intelligent word parsing layer to produce an syntactica or pragmatically correct output sentence or other w message. It is a further object of the present invent to utilize input sequences of polysemic symbols to expl the natural polysemia inherent in illustrations real-life objects, to allow a cognizantly impaired us easy access of a particular corresponding single wor morpheme or plural word phrase. It is a further object of the present inventi to combine artificial intelligence and linguist techniques to reduce the syntactic and cognitive lo burdens on an operator, as well as the physical load. It is a further object of the present inventi to utilize an intelligent word parser to produce syntactically and εemantically well formulated sentence, or pragmatically correct sentence, by filling in the necessary syntactic information (e.g., determinators, prepositions, necessary verb inflections) to produce a sentence upon initial input of an agent, action and patient. It is a still further object of the present invention to have a system which allows a user to input a particular word, phrase, or morpheme, personal to him, and to designate a particular symbol sequence to correspond and subsequently access the particular word, morpheme, or phrase; It is a still further object of the present invention to provide a menu driven system for designation of grammatical and semantic information to be stored with a particular personal word, phrase, or morpheme and its corresponding symbol sequence for subsequent use by an intelligent word parsing layer; It is a further object of the present invention to utilize such an intelligent word parser to form the above-mentioned semantically and syntactically correct sentence irrespective of the order of the input agent, action and patient. These and further objects of the present invention will become more readily apparent from a better understanding of the preferred embodiments as described below with reference to the following drawing figures. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will become more full understood from the detailed description given hereinbelo and the accompanying drawings which are given by way o illustration only and are not intended to limit th invention, and wherein: Figure 1 illustrates a plurality of examples o polysemic symbols useable on the input unit of the syste described in the aforementioned Baker '916 patent; Figure 2 illustrates the input system of th present invention in conjunction with parsing devices, processing device, and output units; Figure 3 illustrates a keyboard or input unit i a preferred embodiment of the present invention; Figurea 4a to 4c illustrate a flowchar corresponding to a method of operation in a preferre embodiment of the present invention; The above-mentioned drawings will be described i detail in the following detailed description. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Figure 2 illustrates a system of preferre embodiment of the present invention. In this preferre embodiment, the keyboard or input system 1 of the presen invention is shown in conjunction with a symbol parsin device 5 including CPU 6 and memory 7, a word parsin device including memory 8, a processor 10, and variou output devices display 9, speaker 11, and printer 12. The specialized processor 10 may be one of a speech synthesis system as will be described in this preferred embodiment or any other processing system, such as a language translater, for example. Further, in conjunction with the system of the present invention, one of a plurality of output devices may be utilized by a user to express one of a plurality of syntactically or pragmatically correct output sentences achieved by the natural language processing system of the present invention. Preferably the memories 7 and 8 are erasable programmable read only memories (EPROMs). However, any suitable type of memory may be used and thus the present invention is not limited to EPROMs. These output devices can be a printer 12 for expressing the syntactically or pragmatically correct output sentence in printed words; a speaker for outputting the output sentence in an audible form; a display device for displaying the output sentence or intermittent steps during processing of the output sentence; or the like. Still further, once the syntactically or pragmatically correct sentence or other word message has been processed and output by one of the plurality of output devices previously described, this output data can be further utilized in a further system such as that of telephonic communication system or the like. Therefore, if such a system is utilized by a physically handicapped or disabled person, they are still able to communicate with the outside world in a similar manner to a person with normal ability. Therefore, the natural language processing system of the present invention, for use in conjunction with a plurality of specialized processing devices such as processor 10, and the various output devices previously mentioned, is thus unlimited in its application to a type of communication system accessible to a person normal ability. Figure 2, as previously described, illustrates keyboard or input unit in a preferred embodiment in t present invention. The input unit or keyboard 1, in preferred embodiment of the present invention, comprises plurality of keys 2. Each key 2, when depressed actuated, activates or closes a switch 3. The closure the switch 3 is detected by the CPU 6. Therefore, detecting an actuated key, the microprocessor 6 c determine the keyboard location and thus the polysem symbol associated with the actuated key. The keyboard is further divided or segmented in a plurality of, for example, three, syntactic segment including agents, actions, and patients. The fir syntactic segment, may correspond to, for exampl agents. Three columns of eight keys per column, can utilized to allow twenty-four keys to represent agent Each of the keys includes one of a plurality of icons. example of these icons, and further of each of t individual keys and syntactic segments of a keyboa preferably usuable in conjunction with the prese invention, can be seen with regard to Fig. 3. Each of t icons, as previously described, are multi-meaning symbo which allow a user to produce sequences that a pedagogically expedient. As previously described, the u of icons is clearly superior to that of letters, word and numbers and to allow a user the ability to access plurality of previously stored words or phrases via system which is both cognitively and physically expedient. It should be noted that the number of keys per column and the number of columns per syntactic segment are merely exemplary and should not be considered limiting in any way. Additional syntactic segments can further be designated for, for example, segments for adjectives and adverbs. Also, pragmatic and semantic segments can further be designed and designated. In pragmatics, for example, information can be conveyed to turn a plurality of words from a statement into a question. Pragmatics deal with statements, questions, irony and how particular phrases are normally spoken. Thus, with pragmatic segments of the keyboard designated, information can be conveyed about inflection of words or phrases and thus can allow a user of the device of the present invention to communicate in an audible manner similar to the ways a person normally speaks. By pressing and actuating keys from a pragmatic section of the keyboard, a user can eventually output a sentence which may be pragmatically correct although not syntactically correct. Thus, the final output, through an audible speaker, for example, may be a pragmatically, and not syntactically output sentence or other word message. An example for utilization of pragmatics may exist for a person attempting to respond to the question "Do you want the whole pie or just a piece?". The user of the device of the present invention, by utilizing the proper polysemic symbol sequences from keys in a pragmatic section of the keyboard, and subsequently conveying the pragmatic information to the CPU 6 of the symbol parsing layer (in a similar manner as will subsequently be described with regard to syntactic information) , and then reply "Just a piece". While the phrase "just a piece" is not a syntactically correct output sentence, it pragmatically correct. Thus, through utilization pragmatics, the intelligent word parsing layer or dev would realize this is the desired ouput. Further, a segment of the keyboard may designated for semantics. A semantic segment, includin plurality of keys, could allow a user to select fro plurality of topics by accessing a single key. example, by selecting a semantic key with a "shirt" sym on it, the user would be conveying semantic informat (in a similar manner as will be subsequently descri with regard to syntactic information) to the CPU 6 of symbol parsing layer indicating the topic of "clothe Thus, secondary and a plurality of additional meanings be derived from each of a plurality of subsequen activated keys. This semantic segment of the keyboard be highly beneficial to a user to allow him to acc desired information by topic. The segmenting of the keyboard is preferably of electronics, not physical segmentation. An additio bit, for example, may be detected by the microprocessor to determine a syntactic, semantic, pragmatic segment corresponding to an actuated key. Th the keyboard will appear to the user as 72 keys aligned nine columns of eight keys per column. However, the of physical separation of the keys into a plurality syntactic, pragmatic, or semantic segments may also utilized to aid the user. Further, the use of labe labeling each of the segments, physically and electrically segmented, may also be utilized conjunction with the present invention. The pres invention further includes any other method of detect of keyboard segment designation within the purview of one of ordinary skill in the art. The ideal keyboard, input device or interface represents input selections transparently and has a relatively small number of input choices or keys. An interface intended for individuals who are cognitively or physically impaired must generate language with a low number of actuations. Letters have serious problems as input media because they require six plus actuations per content word. Normal augmentative and alternative communication (AAC) operators have been known to select one key every five to eight seconds. Congenitally speech impaired people often have weak reading and spelling skills. Further, as an alternative to letters, single meaning pictures, as previously described, also have serious limitations because hundreds of pictures are required to initiate even the simplest vocabulary (with only one lexical item per picture) . The present device, in a preferred embodiment, utilizes and improves on the patented technique of semantic compaction shown in Baker '916, which approaches the problem of sentence, or word message, generation by interpreting symbols or icons to have different meanings in different context. This technique, usable in the preferred embodiment of the present invention, exploits the natural polysemia inherent in illustrations of real-life objects. For example, an apple is not only an apple, it is also red, a fruit and round. When used in a sentence describing a favorite color, an apple icon can be interpreted as indicating the color red. In general, this approach allows the operators to access a much larger number of concepts with the same number of input keys when multi-meaning icons are used in place of letters, words single-meaning pictures. Figure 3 shows a keyboard of one preferr embodiment of the present invention. This preferr embodiment, although only showing syntactic keyboa segmentation, should not be considered limited to suc Semantic and pragmatic segments could further be added, well as additional syntactic segments not shown in Figu 3. With the plurality of icons on the keyboard, large vocabulary may be represented by various sequenc of icons combined together. The layout of the keyboard, in this preferr embodiment, is preferably that of three rows, ea containing eight icons, for each of the three agen action and patient grammatical segments. Thus, the eig columns and nine rows of the keyboard, corresponding seventy-two icon keys, are located in the thr grammatical segments. This number of keys, and furth this particular geographical layout and segmentation the keys, is merely exemplary and thus should not considered limiting with regard to the present invention. Further, regarding the icons shown in Figure they too, are merely exemplary and should not considered limiting. The icons may be selective programmed into the system and can further be selectivel assigned for a particular user. A plurality of polysemi icons or symbols may be chosen so as to correspond to bot the intellectual level of a user and to the maximizatio of the ability of the system. The icons in the three 8-icon columns geographically corresponding to agents, for example, can be combined to form and subsequently access over 300 agents. Similarly, the remaining syntactic segments of the keyboard, utilized to represent patients and actions, each contain three 8-icon columns which can similarly utilize their respective twenty-four icons, in various sequences, to produce over three hundred patients and objects. The central notion behind this layout is that the icons can be sequenced to access a large number of unique words on each grammatical category, the number for exceeding that of the seventy-two iconic keys. It is the multi-meaning nature of icons and their ability to form sequences that indicate a single notion which give them their expressive combination power. If we use single meaning pictures, instead of the multi-meaning icons of the present invention, we would only be able to represent twenty-four agents, twenty-four patients and twenty-four objects utilizing the same layout. Therefore, it is important to note that the usefulness of an intelligence system, such as the Natural Language Processing System of the present system will be defeated if it makes use of a burdensome interface that places a high physical and/or cognitive load on the operator while placing severe restrictions on the depth of his/her vocabulary. For this reason, the multi-meaning icons are clearly the most appropriate interface media for the Natural Language Processing System of the present invention. Through the use of the present geographic layout of the keyboard of the present invention, being divided into syntactic sections or segments of agents, actions and patients (also known as subjects, verbs and objects), combination with the symbol parsing and intelligent parsing devices of the present invention (the word symbol parsing layer to be subsequently described) , keyboard indicating a particular morpheme of a word s as -ing, -ed, -s is not always necessary. Tell, telli tells and told may often be accessed by the same seque of polysemic symbols, the intelligent word parser find and deploying the correct form of the word. Thus, physical load on the user being further reduced. Also, some users may not be readily familiar with various pro forms of a plurality of words, by only utilizing symbol sequence to access a single word, morpheme, phrase and then allowing an intelligent word pars device to produce a syntactically correct output senten any such grammatical errors will be avoided. Further, through utilization of a keybo separated into agents, actions and patients, a user n not be concerned as to which word in a sentence is subject, verb or object. * Merely by choosing a particu symbol sequence from each of the syntactic, semantic, pragmatic segments on the keyboard, the intelligent w parsing device can then output a syntactically pragmatically correct output sentence irrespective of order of each of the input symbol sequences. In ot words, as a symbol sequence is parsed in a symbol pars device of the present invention (to be subsequen described) and a particular word is accessed, syntactic function, or part of speech, associated with keyboard location of the symbols previously sequenced the user, will also be transmitted to the intelligent w parsing device. Thus, as a single word, morpheme, phrase is accessed which corresponds to the input sym sequence, its designation as an agent, action or patient is output along with the single word, morpheme, or phrase to the intelligent word parsing device. The following example, and examples throughout the specification, will be given with regard to syntactic keyboard segmentation and a sequence of symbols activated to access a "word" . It should be noted that pragmatic and semantic information are conveyed to the symbol and word parsing devices and layers in a manner similar to that of syntactic information. Thus, for the sake of brevity, examples are excluded. Further, morphemes or phrases can be accessed, by symbol sequences and corresponding syntactic, semantic, or pragmatic segment information in a manner similar to that of a word. However, for the sake of brevity, examples utilizing morphemes and phrases will be excluded. A user who inputs a symbol sequence for accessing the word "peas", for example, from the object section of the keyboard, followed by a sequence representing the word "eat" from the verb section of the keyboard, followed by a sequence representing the word "man" from the subject portion of the keyboard would normally output the sentence "peas eat man". However, in contradistinction, with the system of the present invention, the intelligent word parser would realize that "man" is the subject of the sentence and "peas" is the object of the sentence, and would subsequently output the syntactically correct sentence "man eats peas". (It should be noted that the system of the present invention depending on the input subject, verb and object may also add additional words to the sentence such as the article "the", for example, in front of both "peas" and "man" to produce the syntactically correct output sentence "The man eats peas". Therefore, it should be clear that the previo example was merely exemplary and utilized only illustrate the aspects of both the keyboard a intelligent word parser to produce the syntactical correct output sentence irrespective of the order of t input subject, verb and object, and should not be taken being limiting in any way.) The keyboard 1 along with a polysemic symbol each of the plurality of keys 2, includes a plurality switches 3 which, when activated, indicate actuation of particular polysemic symbol by a user. Key actuation then detected by the central processing unit 6 determine location of a particular key which has be actuated and to further determine the semantic, syntacti or pragmatic segment of the keyboard corresponding to t actuated key. It should further be noted that t keyboard 1 of the present invention may vary depending the intellectual level of the intended operator a further the icons may also vary. These icons are us selectable and may be varied by the user such that icon to which the user can readily associate, may be use Therefore, each keyboard itself may be a language whi has been designed for, or with, a specific user. Each the polysemic symbols or icons is rich in associations a in combination, signal sentence ideas in the operator memory. This enables the generation of single wor morpheme, or plural word messages (phrases) by t actuation of two keys or as many as several keys. T keyboard, in combination with the other devices of t natural language processing system, may generate hundre of syntactically or pragmatically correct output sentenc because of the ease with which the polysemic symbols on the keys portray the production of whole thoughts. As previously mentioned, key actuation is detected by the central processing unit 6. This central processing unit (CPU) may be, for example, a microprocessor. The microprocessor is used in combination with the memory 7 to form the symbol parsing layer or device 5 of the present invention. Upon a user inputting a plurality of polysemic symbols through the keyboard 1, the microprocessor can then detect the sequence of symbols previously actuated and can compare the input symbol sequence to the previously stored symbol sequence in the memory 7 and thereby access a corresponding sequence of polysemic symbols from the memory 7. Upon matching the input sequence of polysemic symbols with those previously stored in the memory 7, the microprocessor can then access a single, morpheme, word or phrase previously stored in the memory 7 with the corresponding previously accessed sequence of polysemic symbols. Therefore, upon the user inputting a particular sequence of polysemic symbols, a particular word, words or phrase previously stored can be accessed by the symbol parsing device 5. The memory 7, while storing a plurality of symbol sequences, further stores one word, morpheme, or a phrase comprising a plurality of words, corresponding to each of the stored symbol sequences. A morpheme, for example, for past tense may exist on a key of the keyboard. Further, a morpheme, for example, can be accessed from memory to subsequently indicate to the intelligent word parsing layer or device that the verb in a sentence is past tense. If a user inputs symbols to access the words "I", "tell", and "you", the intelligent word parsing device or layer may not be able to tell from the words in t sentence if the verb "tell" should be "tell", "told" "am telling". Thus, through utilization of the morphe for past tense, the intelligent word parser knows choose "told". Further, in the memory is also informati existing such that the CPU 6 must input proper semanti syntactic, or pragmatic segment information as well as appropriate sequence of symbols, to access a particul single word, morpheme, word or phrase. Thus, a simil symbol sequence may exist for each of the semanti pragmatic, or syntactic segments of the keyboard, such an agent,- an action and a patient, each corresponding to different particular single word, morpheme, or phrase. The memory 7 further contains grammatical a semantic information corresponding to each accessed wo or phrase. An example of grammatical and semant information which might be stored in the memory is t designation of a substantive (noun or pronoun) as firs second, or third person. Further, for a verb, there m exist information dictating whether the verb is transitive verb or an intransitive verb and whether t verb is regular or irregular (e.g., adding an s to t verb when the subject is plural means the verb would regular). These examples are merely for illustratio They are simple for the purpose of brevity and shou therefore not be considered limiting. Information stored in the memory 7 is stor prior to operation of the system to correspond to particular sequence of input symbols. For exampl suppose a user has a pet named "Rover". Since "Rover" i not a common everyday word, which may be preprogramm into the system prior to a user obtaining the system, t ability to input "Rover" into the system to personalize it to a particular user must exist. Such a system exists in the Natural Language Processing System of the present invention and it will be described subsequently how a user can associate the word "Rover" to a particular symbol sequence and further store particular grammatical and semantical information corresponding to the word "Rover" and its symbol sequence. This is by way of illustration and is not limitative of the present invention. In storing the grammatical and semantic information associated with the word "Rover", a menu driven system exists in the present invention in which a clinician (or the user himself, depending upon his physical and mental abilities) initially stores the word "Rover". A menu is then displayed on display 9. The menu displays, for example, "Action," "Person, place, or thing or "Idea," "Describer," etc. "Person, place, thing or idea" is selected and another menu is displayed with "Animate," and "Inanimate." "Animate" is selected. Another menu is subsequently displayed with "Person" and "Animal." "Animal" is selected. In such a manner, all of the semantic, syntactic, and grammatical information are input into the memory 7 such that they can subsequently be used by the word parsing device of the present invention. The microprocessor 6 is further connected to a memory 8, thereby forming the intelligent word parsing layer or device of the present invention. This word parsing layer, being activated subsequent to the symbol parsing layer previously described regarding the CPU 6 and the memory 7, exists to intelligently parse a plurality of words, morphemes, or phrases accessed by the symbol parsing device into a syntactically or pragmatically correct output sentence or other word message. When word, morpheme or phrase is recognized by the symb layer, the word parsing layer is activated. The wo knowledge or grammatic and semantic informati corresponding to each word, morpheme, or phrase recogniz by the symbol parsing layer is activated and a plurali of parsing heuristics within the word parsing layer, whi could apply to the plurality of words, morphemes phrases recognized by the symbol parsing layer, are al activated. This makes it possible for intellige decisions to take place about how to add a particular n word and further, how to combine a plurality of word morphemes, or phrases together. It is the job of t symbol parsing layer to recognize individual symbols icons and produce single words, morphemes or phrases th are associated with them; the word parsing layer mu decide how to put those single words, morphemes, phrases together to form a sentence in a coherent outp utterance, possibly using its built-in knowledge to a some words to the accessed plurality of words, morphemes and phrases. Within the memory 8 is a predetermined set o rules which are accessed and to which the previousl accessed grammatical and semantic information is applied By applying this grammatical and semantic informatio about each of the plurality of words, morphemes, o phrases previously accessed by the symbol parsing layer words, morphemes, and phrases received from the symbo parsing layer are then reformulated by the word parsin layer into a syntactically or pragmatically correct outpu sentence or other word message. Additional words may b added to the plurality of accessed words, morphemes, o phrases or various forms of the plurality of accesse words may be changed such that concepts of, for example, subject and verb agreement, take place. Details concerning the word parsing layer will be described subsequently. Upon the word parsing layer parsing the plurality of words, morphemes, or phrases accessed by the symbol parsing layer into a syntactically or pragmatically correct output sentence or word message, the sentence or word message may then be output to a processor 10. The processor 10 may be a language translator, a voice synthesizer or any other similar type-processor which may processor plural word messages such as the syntactically or pragmatically correct output sentence or word message of the natural language processing system of the present invention. Upon processing the formulated correct output sentence, the message may then be output to a printer 12 to print a desired hard copy of the sentence; a speaker 11 to output a audible message corresponding to the formulated correct output sentence; or any similar output device used to communicate the output sentence to another person such as a display 9. The specialized processor 10, for example, may be one of a commercially speech synthesizer such as the Voltrax speech SPAC within SC-01 voice synthesizer chip therein marketed by Voltrax. The output of the synthesizer, or similar specialized processor, may in turn be coupled to a speaker 14 to generate audible synthetic speech in a manner well known in the art. Subsequent operation of the system of the present invention, with reference to Figures 4a-c will be subsequently described. Figures 4a-c illustrate a preferred embodiment the Natural Language Processing System of the prese invention. This system will be described regarding first aspect of associating particular symbol sequences an input word, phrase, or morpheme, for personalization o the system to a particular user and a second aspect fo sequentially storing and displaying the new word, phrase or morpheme and subsequently storing correspondin grammatical and semantical information with the inpu word, phrase, or morpheme and its corresponding symbo sequence. Further, operation of the Natural Languag Processing System of the present invention initiall parsing each of a plurality of sequences of inpu polysemic symbols to produce a plurality of words morphemes, or phrases in the symbol parsing layer an subsequent intelligent parsing of the words and phrase into a syntactically or pragmatically correct outpu sentence and the word parsing layer will subsequently b described. Further, regarding the word parsing layer operation of the first and second embodiment will also b described. Operation will be described with regard t "words" but the system similarly operates for "phrases" o "morphemes" and thus should not be considered limited t words. Further, keyboard segment information will b described relating only to "syntactic" information but th system similarly, operates for pragmatic and semanti information and thus should not be considered limiting. Referring to the flow chart of Figures 4a-c, th system is initially started at 1 shown in Figure 4a. first key is activated in step 2 and subsequently in ste 3, it is determined whether the store key has bee depressed. Upon determining that the store key has bee depressed, the mode for storing a new word into th system, to personalize the system to a particular user, for example, is accessed. Thereafter, a next key is activated in step 4 and subsequently it is determined in step 5 whether or not the next key activated is an icon key. If the next key activated is not an icon key, an error is detected in step 6 and the system is returned to the initial starting step 1. If the next key activated is an icon key, the icon symbol corresponding to the key activated is then stored as the first symbol in a new symbol sequence in step 7. Thereafter, in step 8, a next key is activated and it is determined in step 9 whether or not the next key activated is the "end" key. If the next key activated is not the "end" key, the system then reverts back to step 5 where it is determined whether or not the key activated is an icon key. Upon determining that the activated key is an icon key, the symbol corresponding to the icon key is then stored along with the previously stored symbol to further add to the icon sequence in step 7. This process continues until it is determined, in step 9, that the activated key is an "end" key. Once it is detected that the "end" key has been activated, an icon sequence has thus been formed and the system thereafter progresses to step 10. At step 10, the next key is activated and it is determined whether or not the key is a character key (one of a letter A-Z) or a space key (usually the space bar or a space key on a keyboard) in step 11. Upon determining that the next key activated is not a character or space key, the system then reverts back to step 6 and an error is detected, subsequently reverting the system back to the start of step 1. However, upon determining that the next key activated is a character or space key, the charact or space corresponding to the activated key is stored wit a previously stored icon sequence, in step 12 Thereafter, in step 13, a next key is activated and i step 14 it is determined whether or not the next ke activated is the "store" key. Upon determining that th next key activated is not the "store" key, the system the subsequently reverts back to step 11 where it i determined whether or not the next key activated i another character or space key. Finally, upon a pluralit of characters and spaces in between certain character being stored corresponding with the stored icon sequence it is determined in step 14 that the key activated is th "store" key. Thereafter in step 15, the character phrase morpheme, or word to be associated with the particula icon sequence is then stored in memory and the syste returns to the stored step of step 1. A simple example o this aspect - of the present invention to allow for th formation of a personalized icon sequence and further personalized word, morpheme, or phrase associated with a icon sequence, to be stored, will subsequently be given. Initially, the store key is depressed by th user. Then, the user can depress, in sequential order the picture of the dog (the key with the letter "F" on it followed by the picture of the house (the key with th letter "H" on it). Subsequently, the user will depres the "END" key. The user will then depress the character "R", "0", "V", "E", and "R". Finally, the user wil select the "store" key to thereby store the word "ROVER with the symbol sequence of the "dog" and the "house keys. Thus, the symbol sequence and the wor corresponding to the particular symbol sequence has bee stored. Subsequently, operation for storing the plurality of grammatical and semantical information corresponding to the word to be accessed (in this present example, "ROVER") will subsequently be described with regard to Figures 4a-c. In Figure 4a, in step 3, upon it being determined that the activated key is not the "store" key, the system progresses to step 16 wherein it is determined whether or not the key depressed is the spell mode key. Upon the system detecting that the key depressed is the spell mode key, a character key is subsequently activated in step 17. The system then progresses to step 18 where the characters corresponding to the previously activated key of step 17 are sequentially displayed. Then, in step 19, the next key is activated and in step 20, it is determined whether or not the key activated is an "END" key. Upon determining that the key is not an "END" key, the character corresponding to the activated key is then displayed as the system reverts back to step 18. In this manner, the word "ROVER", for example, can be sequentially and cumulatively displayed ' for the user. Subsequently, upon it being determined that the activated key is an "END" key in step 20, the system moves to step 21 where a "parts of speech category" menu is displayed. This menu allows a user to select a particular part of speech corresponding to the previously input word. The menu may display, for example, as follows: (1) Action, (2) Person, place, thing or idea, (3) Describer, etc., such that the user need only access a number key corresponding to one of the numbers of a part of speech displayed, relating to the input word "ROVER". Therefor in step 22, the next key is activated and subsequently step 23, it is determined whether or not the key activat corresponds to a number of a particular part of spee previously displayed in step 21. If the activated k does not correspond to such a number, the system retur in step 24, to display step 21. Therefore, correspondi to the previous example utilizing the word "ROVER", t user would merely select the number "2" corresponding "Person, place, thing or idea". Accordingly, in step 2 a particular part of speech would be stored as grammatic and semantic information with the word "ROVER" in t memory 7. The system then moves to A in Figure 4b. Next in step 26, a "grammatical features" menu is the displayed. Similar to the parts of speech category menu the grammatical features menu would display, for example as follows: (1) Animate (2) Inanimate etc. Accordingly, in step 27, the user would activate key and in step 28, it would be determined whether the ke activated corresponds to a number previously displaye corresponding to one of the displayed grammatical feature of the "grammatic features" menu. If the activated ke did not correspond to such a number, the system woul return to the display step 26, in step 29a. However, i the activated key corresponded to such a number, in ste 29b, the system would store the grammatical featur corresponding to the key selected, with the word. Therefore, with the word "ROVER", would be stored "Animate" upon selection of the number "1". Thereafter, in step 30, the system would then display a "semantic category" menu displaying, for example, as follows: (1) Person (2) Animal etc. Thereafter, the user would then activate a key in step 31 and in step 32, it would be determined whether or not the key activated corresponded to one of the numerals displayed which corresponded to one of the "semantic categories". If the key was not such a numeric key, the system would revert back to display step 30, in step 33a. Therefore, for example, the user may select numeral 2 and thus, in step 33b, the word "ANIMAL" would be stored as the semantic category corresponding to the word "ROVER". Similarly, a plurality of grammatical and semantic information can be stored with each of a plurality of words corresponding to a plurality of symbol sequences in the memory 7, corresponding to such information as to whether a particular noun is singular or plural or whether the noun is of first person, second person or third person. It should be noted that these particular features previously discussed are given by example only, and should not be considered limiting with regard to the present invention. Any number of grammatical, semantic and further syntactic information can be stored with each single word, morpheme, or phrase corresponding to any number of symbol sequences. Further, it should also be noted that depend upon the keyboard location of the particular keys to activated in a symbol sequence, different wor morphemes, or phrases, and grammatical and seman information can be stored for a similar symbol sequen For example, if "ROVER" is to be designated as a potent subject for a sentence, the keys corresponding to "DOG" and "HOUSE" should be depressed in the syntac segment of the keyboard corresponding to agen Therefore, if the symbols are depressed in the ag segment of the keyboard, a particular symbol seque corresponding to "DOG" and "HOUSE" will access "ROVE but will also access grammatical and semantic informat which correspond to utilization of "ROVER" as the subj of the sentence. However, if "ROVER" is to be utilized the object of the sentence, the user will depress "DOG" key and the "HOUSE" key in the patient syntac segment of the keyboard. Subsequently, the word "ROV corresponding to the "DOG" key and the "HOUSE" key will accessed similarly to that previously described, but particular grammatical and semantic information stored memory 7 along with the "ROVER" will be informat directed toward utilization of "ROVER" as the object o sentence. This different grammatical and seman information for the same word "ROVER" accessed by the s symbol sequence "DOG" and "HOUSE" will be dictated recognition of the particular syntactic segment of keyboard from which the keys have been activated. It this combination of syntactic segment informat designating each corresponding polysemic symbol as one an agent, action and patient, along with a particu sequence of polysemic symbols, which access both stored word, morpheme, or phrase and correspond grammatical and semantic information from the memory 7. Therefore, as shown in Figure 4c, similar to that previously described, the system would then progress from step 33 to D to step 34 to possibly display a semantic subcategory menu wherein a key would be activated in step 35. Then, in step 36, it would be determined if the numerical key corresponding to a "semantic subcategory" displayed had been activated. Accordingly, if such a numerical key had not been activated, the system would return to step 34, and then return to display step 37. However, if the key activated corresponded to a numerical key corresponding to a semantic subcategory displayed, the system would progress to step 38 to thereby store the semantic subcategory corresponding to the key selected, with the previously stored word, morpheme, or phrase, Accordingly, as previously discussed, not only can the new word "ROVER" be stored in memory 7, but a particular symbol sequence to access the word "ROVER" can be generated, to suit the particular needs of a user, by utilizing a symbol sequence he or she can readily associate with the word "ROVER" . Also corresponding grammatical and semantic information can additionally be stored with the word "ROVER" to be subsequently utilized in the intelligent word parsing layer of the present invention. Accordingly, the particular aspects of storing a personalized word and further a personalized symbol sequence, along with corresponding grammatical and semantic information to be subsequently utilized in an intelligent word parsing layer of the present invention, have been described. Subsequently, actual use of the Natural Language Processing System of the present invention, will now be described with regard to Figures 4a and 4b. Upon the system determining that the k depressed is not the character mode key, in step 16, t system then progress to step 40 where it is determin whether or not the key depressed is an icon key. Up determining that the key depressed is not an icon key, t system returns to "START" indicating that an error h been detected in step 41. This notation of an err detected in step 41 and further the return to "START" fr step 40 is merely being utilized for illustrati purposes. Since only a limited number of possibilities determining which key has been selected is shown wi regard to Figures 4a-c, the remaining possibilities a noted as error notations. However, as previous mentioned. Figure 4a-c are merely given for illustrati purposes only and are not to be considered limiting wi regard to the present invention. For example, the syst can further detect if the activated key is any number other keys, other than the store key of step 3, spell mo key of step 16 and icon key of step 40. Upon determining in step 40 that the activat key is an icon key, the microprocessor 6 then detects a identifies the keyboard location of the icon k depressed. By identifying the location of this key, t microprocessor can then determine which polysemic symb corresponds to that particular key and further to whi syntactic, semantic, or pragmatic segment the activat key corresponds. Therefore, the microprocessor c determine if the key depressed is one of an agent, acti and patient, for example. A key is activated by bei depressed and thereby the switch 3 is closed. T microprocessor detects this closing of the switch a thereby can detect keyboard location of a particular k activated. Further, separate detectors can be utilized i the present Natural Language Processing System to detect each one of the agent, action and patient syntactic segments to which a key may belong. However, in a preferred embodiment, additional binary bits are merely detected by the microprocessor, the binary bits corresponding to one of agent, action and patient syntactic segment. Thereby, upon the microprocessor detecting which of a plurality of polysemic symbols a key corresponds, it can further detect the syntactic segment of the keyboard to which the activated key corresponds. Upon detecting and identifying the keyboard location of the previously activated icon key, the microprocessor then temporarily stores the icon symbol as an icon sequence in step 42 and further stores the keyboard location of the last activated key. This temporary storing can be done in a temporary memory, for example, a random access memory located within the central processing unit 6. Thereafter, the system moves to step 43 where the microprocessor then compares the temporarily stored icon sequence to a plurality of icon sequences previously stored in memory 7. As previously described, the memory 7 stores a plurality of icon sequences for accessing a word, morpheme, or phrase and further accessing corresponding and previously stored, grammatical and semantic information corresponding to the stored word, morpheme, or phrase. Upon determining that the icons do not form an icon sequence in step 44, the system then moves to step 45 where the next key is activated. In step 46, it is determined whether or not the next key activated is an icon key. Upon determining that the next key activated not an icon key, the system then moves to step 47 where error is detected and subsequently the system restarted. However, upon determining that the next activated is an icon key, the activated key is detec and its keyboard location is identified in step 41. system then proceeds to steps 42, 43 and 44, where icons corresponding to sequentially activated keys temporarily stored as an icon sequence and compared previously stored icon sequences in memory, until it finally determined in step 44 that the icons do form icon sequence. The system progresses to step 48 wherein keyboard location the last key activated is utilized. microprocessor compares this keyboard location to sto data to determine the icon sequence as an agent, action patient. Thereafter, in step 49, utilizing both determination of an agent, action or patient, and furt the icon sequence, the microprocessor then accesses mem 7 to find the word or phrase which corresponds to the i sequence and determined agent, action or patient. Thus, plurality of icon sequences could exist which a identical, one each for an agent, action and patient, ea corresponding to different stored words, morphemes, a phrases. Subsequent to step 49, in step 50, grammatic and semantical information, previously stored a corresponding to the accessed word, morpheme, or phase step 49, are then obtained from memory 7. Th grammatical and semantic information includes, f example, the previously stored part of speech, grammatic feature, semantic category and semantic subcatego corresponding to the previously accessed word, morpheme, or phrase. The system then progresses to step 51 where this accessed information corresponding to the accessed word, phrase, or morpheme and further the accessed grammatical and semantic information, is then stored for subsequent use in the word parsing layer of the present invention. Thus, at this point, the symbol parsing layer for one input icon sequence, is now complete. The word parsing layer in a first preferred embodiment of the present invention, is activated upon each word, morpheme, or phrase being recognized by the symbol parsing layer. Before the Natural Language Processing System of the present invention can show understanding of the linguistically complex utterance such as that of the word, morpheme, or phrase activated, it must have a significant body of knowledge about morphology, word meaning, syntax, etc. corresponding to both the word itself, and how that particular word or phrase reacts when combined with other words or phrases to thereby produce a syntactically or pragmatically output sentence. Thus, in order to support intelligent processing, linguistic knowledge general to the English language, or any other language to which the system of the present invention may be programmed, must be built into the Natural Language Processing System of the present invention. It should be noted that in this preferred embodiment, the present invention will be discussed regarding a system producing an English language syntactically or pragmatically correct output sentence or other word message. However, the system should not be limited to such an English language Natural Language Processing System in that various rules corresponding any particular language, within relm of an ordin skilled artisian, are also contemplated herein. The word parsing layer of the present invent operates by making intelligent decisions about wor morphemes, and phrases corresponding to previously in keys by parsing the particular words, morphemes, phrases together in a syntactically or pragmatica correct manner, through utilization of the previou stored grammatical and semantic information correspond to each particular word, phrase, and morpheme, and furt inferring additional information which has been left to produce a syntactically or pragmatically correct out sentence. The intelligent word parsing layer of present invention essentially "reads between the lines" produce a sentence or other word message merely accessing a plurality of words, morphemes, or phrases. contrast to previous systems which merely operate in simple transduction manner, to access whole sentences allow the user to get exactly what he types, the Natu Language Processing System of the present invention specifically the word parsing layer and device, deci where and when to add information to that previously in and accessed whenever it seems intelligent to do so. support this type of processing, a large body of knowle must be built into the existing system. Within the memory 8, a predetermined hierarchy rules are stored with which the microprocessor can ap accessed words, morphemes, and phrases and th corresponding grammatical information, to subsequen produce a syntactically or pragmatically correct out sentence. Knowledge about various aspects of a particu language, for example, English, are stored in the memory 8 in the form of world knowledge, word knowledge and parsing heuristics, for example. World knowledge is a representation of abstract concepts in the world, e.g., actions, objects, along with their semantic properties which can be used by the Natural Language Processing System to make decisions during word parsing. Word knowledge is knowledge about the concrete concepts that are referenced by the user (e.g., the verb "to eat", the noun "peas", along with their associated linguistic properties, e.g., agreement features, subcategorization, etc.). Each word representation includes a reference to the abstract concept that the particular word exemplifies. Parsing heuristics exist in the form of the set of rules about word knowledge and world knowledge, which can be used by the system during word parsing to add information to what the user has already entered or to guide the user during the rest of the input. Similar rules for phrases or morphemes also exist but are not included for the sake of brevity. During symbol parsing the plurality of input symbols and syntactic, semantic, or pragmatic segment information (dictating each key as one of an agent, action and patient, for example) are accessed at what can be referred to as a transduction level, which accepts sequences of symbols from the user and produces domain concepts (here, word, morphemes, or phrases) in the symbol parsing layer. The word parsing layer is the additional processing layer which is activated after each word, morpheme, or phrase is recognized by the symbol parsing layer. When a word, morpheme, or phrase is recognized by the symbol parsing layer, the word parsing layer is activated. The word knowledge that is defined for the new word, morpheme, or phrase is activated, and any parsi heuristics which can apply to the new word, morpheme, phrase are also activated, making some intellige decisions about how to add this new word, morpheme, phrase to the utterance being defined. It is the job the symbol parsing layer to recognize individual symbo or icons and produce the words, morphemes, or phrases th are associated with them and it is the job of the wo parser to decide how to put those words, morphemes, phrases together to form a coherent output sentence. T word parser utilizes its built-in knowledge to add so content to the accessed words and thereby produces syntactically or pragmatically correct output sentence. An example of some of the world knowledge a word knowledge and further some of the parsing heuristi of the word parsing layer, utilizing words, will now given. The world knowledge, as previously state consists of abstract linguistic concepts (e.g., actio thing) and the word knowledge consists of concre linguistic concepts (e.g., particular actions or things Abstract linguistic concepts represent ideas that, f example, intransitive action words take agents arguments, and transitive action words take both agen and patients as arguments. Concrete linguistic concep represent information about two particular concepts th the user may refer to. The first one represents t concept "bruce" and indicates that the lexeme associat with that concept is "Bruce". It further represents th this concept represents third person, singular agreeme features. A second example of a particular conce represents the concept "eat". The previously stor information in the word parsing layer indicates that this concept is an action and can be realized by the inflected verbs "eat" and "eats" when certain agreement features are present in the subject. Parsing heuristics are rules that can be used by the word parsing layer to infer something about the input that was not explicitly given. One example, which will be subsequently discussed, refers to the word parsing layer of the present invention, inferring a particular inflection of the main verb that should be used, thereby freeing the user from typing a distinct key which indicates this information. In other words, the user need only access the particular verb by inputting a particular symbol sequence through symbols located in the agent grammatical segment on the keyboard and does not need to type in the particular tense of the verb. This particular tense will be inferred by the word parsing layer. A parsing rule has a name and a list of arguments. It may bind some previous words. Finally, a rule has a set of statements that are evaluated. Usually, a rule takes the form of a conditional statement "If ... then ..." that only succeeds in certain contexts. In the word parsing layer of the present invention, in this first preferred embodiment of the present invention, the rules operate in a sequential predetermined hierarchy. In other words, upon the system entering the word parsing layer of the present invention, it is detected which was the last word, morpheme, or phrase that was activated or accessed by the symbol parsing layer and further detects the sequence of words, morphemes, or phrases which have been previously activated. For example, here is a simple heuristic rul that determines subject-verb agreement: (defprule subject-verb-agreement(newfram sequence) (let((previous (lastframe) sequence))) (cond ((and (? action newframe) (? entity previous)) (ruletrace "making verb -a agree with subject -a. newframe previous) (add-value newframe :agreemen (agreemen previous)))))). This rule binds the word, phrase, or morpheme previous t the last word, phrase, or morpheme and its correspondin grammatical and semantic information, before the new word phrase, or morpheme and its corresponding grammatical an semantic information are activated. In the test part o this conditional statement, the word parsing layer check to see if the previous word, phrase, or morpheme and it corresponding grammatical and semantic information was type of entity, and to see if the new word, phrase, o morpheme and its corresponding grammatical and semanti information was a type of action. If this is the case, i assumes that the previous word, phrase, or morpheme an its grammatical and semantic information is the subject o what will be the output sentence, and that the new word phrase, or morpheme and its corresponding grammatical an semantic information is the main verb, and that the tw must agree. Subject-verb is enforced by copying th agreement features from the previous word, phrase, o morpheme and its corresponding grammatical and semanti information. An example parse will now be discussed. In this example, a plurality of input keys forming a symbol sequence, are initially utilized to access the agent "Bruce", the action "EAT", and the patient "PEAS". The system initially determines that "bruce" is a proper name referring to "Bruce". The subject-verb agreement rule copies the agreement feature that "Bruce" is third person singular to the verb or action. The system then chooses the lexeme "eats", noting that the verb "eat" is a regular verb and that "Bruce" is third person singular. It thus adds "s" to thereby chose the lexeme "eats". Finally, the system recognizes the patient "peas" and thereby outputs the syntactically correct sentence "Bruce eats peas". This example is merely given on a simplistic level to show the intelligent aspects of the word parsing layer. It should be noted that this is only an example parse and should thus not be considered limiting to the present invention. The word parsing layer of the present invention comprises a plurality of hierarchically arranged rules which apply to the various accessed words, morphemes, and phrases, to subsequently produce a syntactically or pragmatically correct output sentence. The word parsing layer of the present invention stores rules which can be utilized in an intelligent manner to parse symbols accessed in the previously mentioned symbol parsing layer. The word parsing layer uses grammatical and semantic information about each of the plurality of words, morphemes, and phrases accessed via the symbol parsing layer to make intelligent decisions about the user's input, producing a complete and syntactically or pragmatically correct output sentence from a partial, and perhaps badly ordered input. In other words, since the keyboard is set up in a plurality of syntactic, semantic, or pragmatic segments, one ea corresponding to agent, action and patient, for exampl the user need not have any knowledge of the ordering agents, actions and patients in an subject-verb-obje grammatical order. The user, as long as he inputs one an agent, action and patient, in any order, will be ab to produce a syntactically or pragmatically correct outp sentence through the intelligent word parsing of the wo parsing device of the present invention. For each word that the system knows, at least t types of information, for example, may be stored in t memory 7. First the system must know about t grammatical nature of the word, phrase, or morpheme. F example, for the word "boys", the system must know th "boys" is a noun, that it is plural, and that it has thi person agreement. Second, the system must know about t semantic nature of the word. For example, it must kn that "boys" refers to animate humans. The system mu store similar information about verbs. For example, f the verb "eat", it must store the information that "ea is a verb with certain inflections (for tense, numbe etc.). It must also store information about the semant natures of "eat", that it represents an action whose age is usually animate and whose patient (direct object) usually edible. These types of grammatical and semant information are exemplary of those stored with the wor morpheme, or phrase in the memory 7, and are accessed wi their corresponding word, morpheme, or phrase by t symbol parsing device. This information is transferr and is thus accessible to the word parsing device and t word parsing layer of the present invention. This linguistic knowledge, along with the geographic keyboard layout designating each word, for example, as an agent, action or patient, is used by the system to infer the semantic rules of each word, phrase, or morpheme which appears in the input. This ability, on the part of the system, will make it capable of providing individual who experienced disordered syntax with a true language prosthesis. Once the system has determined the agent of the input sentence, it can also enforce the rule of subject-verb agreement by comparing grammatical knowledge stored for the agent (here "boys") with the inflection stored for the verb, selecting the inflection with the proper agreement. Thus, the system will inflect verbs automatically based on the rule of subject-verb agreement. In a further preferred embodiment of the present invention, as is shown in Figure 4b, the system moves from B in 4a to B in Figure 4b and in step 52, it will then detect activation of a next key. Thereafter, in step 53, it will determine whether the next key is an "end" key and if not, will then move from C in 4b to C in Figure 4a and subsequently return to step 3 of Figure 4a to determine whether the key activated is a "store" key, to step 16 to determine whether the key activated is a "spell" mode key, and finally to step 40 to determine whether the key is a icon key. By such a system, the present invention can be utilized, in a second preferred embodiment, to access a plurality of words, morphemes, or phrases via a plurality of input symbol sequences, prior to the operation of intelligent word parsing layer. Therefore, in this second embodiment of the present invention, each of a plurality of words, for example, and their corresponding grammatical and seman information, previously accessed by the symbol pars device, can all be stored prior to the word pars device. Thus, the aforementioned hierarchy of rules the word parsing device will be accessed upon access all of the plurality of words, for example, to be utili by the user in subsequently producing his out sentence. This differs from the first prefer embodiment of the present invention wherein the w parsing device operates immediately after the first w has been accessed and sequentially operates after e word is accessed. In the second preferred embodiment, word parsing device does not operate until all of words, morphemes, or phrases are accessed, as shown Figures 4a and 4b. Upon all the words, for example, being access by each of . the plurality of polysemic symbol sequen being entered, the user then depresses the "END" key. step 53, it is detected that the "END" key has b depressed and thus the system enters the rule ba inference analysis of the word parsing layer in step In step 55, the word parsing layer is accessed and word parsing device receives and subsequently applies e of the plurality of accessed words, morphemes, or phra to a predetermined hierarchy of rules and, based upon corresponding grammatical and semantic information, par the received plurality of accessed words, morphemes, phrases into a syntactically or pragmatically corr output sentence in step 56. In step 57, this out sentence is output to a voice synthesizer subsequently, in step 58, the output sentence is voi synthesized through a speaker 11, for example, for audi output. It should be noted that the voice synthesizati step of 57 and 58 take place after the word parsing layer in both the first and second embodiments of the present invention. The semantic compaction technique of utilizing polysemic symbol sequences to represent a plurality of words, in combination with the syntactic, semantic, or pragmatic segmenting of a keyboard into that of an agent, action and patient, for example, and further the utilization of intelligence parsing, simultaneously offer enriched functionality and reduced cognitive and physical loading of a user. It is this communicative power of multi-meaning icons that allows intelligent parsing to achieve its fullest potential. Further, because icons can be used to encode a rich semantic context with very few key actuations, the user's cognitive and physical load is minimized. It is essential to note that the intelligent parser that does not use multi-meaning icons cannot take full advantage of this reduction. Actuating the eclesiastical, semantic and syntactic aspects of the system by spelling, letter codes and abbreviations would be immensely complex and laborious. Inputting to an intelligent language generator with multi-meaning icons, dramatically decreases the number of actuations to be made as well as the total number of keys involved. Thus, the intelligence parsing of the present invention becomes a reality as a communication aid for the vast majority of communication aid users by its implementation of the symbol parsing of multi-meaning sequence icons. From the above-described embodiments of the present invention, it is apparent that the present invention may be modified as would occur to one of ordinary skill in the art without departing from the scope of the present invention and should be defined solely by the appended claims. Changes and modifications of the system contemplated by the present preferred embodiments will be apparent to one of ordinary skill in the art.
