     The present invention relates generally to natural language processing, and more particularly, relates to a system for automated morphological analysis of word structure. 
     RELATED APPLICATIONS 
     The present application is related to commonly assigned and copending U.S. patent application Ser. Nos. 07/570,585 and 07/570,584 entitled, respectively, A Method For Generating A Lexicon and Sense Discrimination System And Method. 
     BACKGROUND OF THE INVENTION 
     Automated natural language (NL) text processing typically refers to text processing, such as text retrieval performed on text by a computer capable of &#34;reading&#34; and &#34;understanding&#34; the semantics of the text. Efficient natural language processing systems can be of great benefit in performing tasks such as information retrieval. The computer, by being able to understand the meaning, i.e., semantics, of the text, can perform a more accurate search and bring only relevant information to the attention of the requestor. 
     In order to perform such &#34;intelligent&#34; searches, the computer itself must &#34;understand&#34; the text. Natural language processing systems therefore typically contain tools, or software modules, to facilitate generating a representation of an understanding of the text. Particularly, when text is input to a NL system, the system not only stores the text but also generates a representation, in a computer-understandable format, of the meaning, i.e., semantics, of the text. 
     For generating a computer-understandable semantic representation of text, natural language processing systems include, in general and at a high level, a lexicon module and a processing module. The lexicon module is a &#34;dictionary&#34;, or database, containing words and semantic knowledge related to each word. The processing module typically includes a plurality of analyzer modules which operate upon the input text and the lexicon module in order to process the text and generate the computer-understandable semantic representation. Particularly, the processing module generates a recorded version for each word of text, and the recoded version includes fields which represent semantic knowledge. Once this semantic knowledge of the text is generated in a computer-understandable format, a system user can use the computer, via an application program such as a search program to perform tasks such as text retrieval. 
     One analyzer module which may be utilized to operate upon input text to facilitate generation of the computer-understandable semantic representation of the text is a morphological analysis module. Morphologic analysis, as used herein, refers to the derivation of lexical entries for a word based on its internal structure. The internal structure of a word refers to lexical constituents, i.e., root and any affixes, that make up the word. 
     Known morphological analysis systems utilize affix stripping methods to obtain a word root. The affixes of the word are discarded. The lexical entry is created from the word root alone. Utilizing only the word root, however, limits the accuracy of these known morphological analysis systems. For example, for two separate words having a common root, identical lexical entries will be generated. The two words, in their entirety, however, may have totally different meanings. Until now, no known morphological analysis system utilizes affix information to generate more accurate lexical entries which contain more semantic knowledge. 
     SUMMARY OF THE INVENTION 
     The present morphological analysis system generates a recorded version for each word of text by breaking a word into potential base-suffix pairs and base-prefix pairs. Then, using spelling rules, possible roots of each base are determined. For each possible root, a word version is obtained from a lexicon module. If the lexicon module does not have an entry for a particular root, the entry can be derived. For each word, derivation information for each affix is derived. The derivation information is then represented in the lexical entry. For each pair, optimization operations are employed to determine the likelihood of the accuracy of each base-suffix and each base-prefix pair. 
     Importantly, the present invention provides explicit recognition in text representation of the relationship between words that derive from a common root by utilizing the word root along with information contained in the complete form in which a word appears, i.e., prefix, affix and root.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     The present invention is specifically directed to a morphological analysis system and method. It is contemplated that the present invention could be utilized in a larger automated natural language text processing system which includes other modules which provide other types of semantic knowledge. Further, although the present invention is described with reference to a particular lexicon, it is contemplated that the present invention could be used with many other lexicons and is not limited to practice with any one particular lexicon. 
     Referring now to FIG. 1, a flowchart 100 illustrating a sequence of method steps for performing morphological analysis in accordance with the present invention is shown. Although the steps shown indicate that the analysis is for suffixes, the same operations are to be performed for prefixes. Subsequent to starting operations as indicated at 102, the word under analysis is broken into potential base and suffix pairs as indicated at 104. This involves stripping off the suffixes which could end the word, including no suffix at all. For example, the word &#34;quickly&#34; would generate three pairs: (quickly-null), (quickly-y), and (quick-ly). The -null suffix represents no suffix, which would mean that &#34;quickly&#34; is a root. At this point, no determination has been made on the validity of these breakdowns. 
     For each pair, the next step, as indicated at 106, is to determine what the true root is, since the base may include a spelling change. For example, the base &#34;hitt&#34; for the suffix -ing is the result of &#34;doubling&#34; the final consonant &#34;t&#34; of the root &#34;hit&#34;. For the analysis, the entry &#34;t&#34; must be removed. The spelling rules of English are somewhat arbitrary, with many exceptions. Thus, each base may produce several possible roots. 
     As indicated at 108, for each root, its lexical entries must accessed. In the case of the word &#34;book&#34;, this task is simply a look-up operation. However, the root itself could be a derivative of some other word, and thus the analyzer must recursively derive the entries for this root. For example, the word &#34;acquisitions&#34; has an immediate root &#34;acquisition&#34;, which is a derivative of the word &#34;acquire&#34;. Note that in either case, a root may have multiple lexical entries representing different parts of speech. 
     As indicated at 110, for each of these entries, the derivative entry for the suffix must be retrieved. The derivative entry specifies the derived part of speech or lexical subcategory and the semantic transformation rules to apply to the entry&#39;s senses. Using the derivative entry, the morphological analyzer creates a virtual lexical entry for the original word. 
     The process is complicated by three sources of ambiguity: word to base, base to root, and root to entry. The word may have several possible breakdowns, the base may have several possible roots, and the root may have several entries. To try all possible paths in this morphological analysis may, in some cases, be inefficient. 
     In order to optimize the process, lexical targets may be used. A lexical target is a desired part of speech to be derived at a certain stage of analysis. The targets are determined depending on the current suffix it is processing. For example, the suffix -s can only transform a verb into the third person singular present form or a noun into the plural form. Thus, the only possible parts of speech for a root entry of a word ending in the -s suffix are noun and verb. Noun and verb are thus the lexical targets for -s. The analyzer system &#34;knows&#34; this about -s, and therefore will not access (or derive) root entries which are not nouns or verbs. For example, the analyzer would not consider the preposition lexical entry for root &#34;down&#34; if it was analyzing the word &#34;downs&#34;. 
     Another optimization involves a look-ahead search strategy which tries to prune derivations which have little hope of succeeding. This strategy is a heuristic based on the fact that it is rare that a word will have two derivations based on different roots, (e.g. the word &#34;singer&#34; could derive from &#34;single&#34; and &#34;sing&#34;). Furthermore, that these two competing derivations could be composed of a different number of constituents is even rarer, (e.g. the word &#34;crackers&#34; could be broken down into &#34;crack-er-s&#34; and &#34;cracker-s&#34;). Using this heuristic, the analyzer &#34;looks ahead&#34; to determine if an analysis (or path) is promising, and if not, terminates it. For example, if the analyzer has accessed the entries of one known root, the other possible roots are only considered if they do not require recursive derivation. There other situations where this strategy may be employed to result in high efficiency without loss of lexical coverage. 
     Further details with regard to obtaining derivation information are provided in flow charts illustrated in FIGS. 2 and 3. As shown in FIG. 1, subsequent to applying the derivation information to the entry as indicated at step 110, all derived entries are returned as shown at step 112. Operations then end as indicated at a step 114. 
     Referring now to FIG. 2, a flowchart 200 illustrating a sequence of method steps for retrieving derivation information of an entry for a suffix is shown. Particularly, subsequent to starting operations as indicated at step 202, for each sense of the entry, and for each sense-level derivative of the suffix, if the derivative will result in a lexical target, the derivative and sense are saved under the lexical target as indicated at step 204. Then, as indicated at 206, for each entry-level derivative of the suffix, if the derivative will result in a lexical target, the derivative along with each sense of the entry are saved under the lexical target. 
     As indicated at step 208, for each part-of-speech default derivative of the suffix, if the derivative will result in a lexicon target not yet derived, the derivative along with each sense of the entry are saved under the lexical target. All saved derivative information is then returned as indicated at step 210. Operations then end as indicated at step 212. 
     FIG. 3 is a flowchart 300 illustrating a sequence of method steps for applying derivative information to an entry. Particularly, subsequent to starting operations as indicated at a step 302, for each lexical target, the following operations, as shown at 304, are performed: create a new lexical entry with the target as its part-of-speech, and for each derivative sense pair, apply the semantic transformations of the derivative to the sense and store the resulting new senses in the new lexical entry. Operations then end as indicated at step 306. 
     The analysis of prefixes cause two major complications for the morphological analyzer. First, prefixes add ambiguity to the determination of the root of words. For example, the prefix pre- is also enveloped in normal words such as &#34;prefers&#34;, which would cause the analyzer to attempt wasted derivations for invalid roots. Second, since prefixes can be combined with suffixes, there is often ambiguity in which affix is attached first. For example, the word &#34;undoable&#34; has to distinct meanings: &#34;not doable&#34; or &#34;able to be undone&#34;. For the analyzer to accurately derive the lexical entries for such words, all orders of attachments must be applied. 
     Appendix I shows the suffixes and their transformations for each part of speech. For each suffix, the base part of speech (POS) is shown to the left of the arrow and the derived part of speech (or lexical subcategory) is to the right. This part of the table represents the syntactic transformation caused by adding the suffix to a root entry. The list of possible semantic transformation rules follow this syntactic information. The description of each semantic transformation rule is provided in Appendix III. 
     Appendix II shows the prefixes and their transformations for each part of speech. Prefix derivatives are not encoded in the derivative fields of the lexical entry structure. Rather, these derivatives are treated as global to all members of a lexical category. For example, derivatives involving the prefix un- are assumed for all adjectives, nouns and verbs, and furthermore, the derivative entry is the same for all of them. The handling of prefixes can, of course, be identical to that of suffixes, and their derivative entry structures may be encoded explicitly in the lexical entries. 
     As mentioned above, Appendix III contains a list of the semantic transformation rules referenced in the derivative entries. Each transform has a description of the transform and an example derivative. If the transform is relevant to only a few affixes, then those affixes are listed in parentheses. The affixes which use these transforms are listed in Appendices I and II. 
     These rules create the word senses of the derivative, so the user must decide what rules are applicable to the derivative; i.e. what rules will generate the appropriate senses of the derivative. Each derivative must be considered individually, since there are no generally applicable transformations. If the user finds that no rules apply to a given derivative, this derivative should either be encoded as a full lexical entry or as an explicit derivative. If some rules apply, but other senses of the derivative are not encodable as transformations, then these senses should be encoded as explicit derivatives. 
     Appendix IV contains a computer code listing which may be utilized to control operation of a computer in accordance with the present morphological analysis method. The code is written in Lucid Common Lisp and may be run by a Sun Workstation. 
     The preferred lexicon to be utilized with the present morphological analysis system and method includes a hierarchy of parent concepts for encoding semantic preferences and restrictions, sense-based morphology and subcategorization, a distinction between primary and secondary senses and senses that require particular &#34;triggers&#34; or appear only in specific contexts, and a broad range of collocational information. For example, the following listing is a lexical entry for the word &#34;issue&#34;:

     The lexicon entry includes only the coarsest distinctions among word senses. Thus, the financial sense of &#34;issue&#34; (e.g., a new security) falls under the same core sense as the latest &#34;issue&#34; of a magazine. This means that for a task like database generation, task-specific processing or inference must augment the core lexical knowledge, but avoids many of the problems with considering many nuances of meaning or low-frequency senses. For example, the &#34;progeny&#34; sense of issue as well as the &#34;exit&#34; sense are omitted from the lexicon. This preserves, in the core lexicon the common coarsest distinctions among senses. 
     More particularly, each lexical entry has a part of speech :POS and a set of set of core :SENSES. Each core sense has a :TYPE field that indicates &#34;p&#34; for all primary senses and &#34;s&#34; for secondary senses. In general, a semantic interpreter utilizing the present lexicon should not consider secondary senses without specific contextual information. For example, the word &#34;yard&#34; can mean an enclosed area, a workplace, or a unit of measure, but only the enclosed area sense is considered in the zero-context. 
     The :PAR field links each word sense to its immediate parent in the semantic hierarchy. For example, with the parents and siblings of the two senses of the noun &#34;issue&#34;, word senses are given by a root followed by a sense number, with conceptual categories designated by any atom beginning with c-. Explicit derivations are shown by roots followed by endings and additional type specifiers:

     The basic semantic hierarchy acts as a sense-disambiguited thesaurus, under the assumption that in the absence of more specific knowledge, word senses will tend to share semantic constraints with the most closely related words. Note that derivative lexical entries, such as week-ly-x above, do &#34;double duty&#34; in the lexicon, so that an application program can use the derivation as well as the semantics of the derivative form. 
     The :ASSOC field includes a lexicographer&#39;s choice of synonym or closely related words for each sense. 
     The :SYNTAX field encodes syntactic constraints and subcategorizations for each sense. Where senses share constraints, these can be encoded at the level of the word entry. When the syntactic constraints, such as io-rec, one-obj, and no-obj, influence semantic preferences, these are attached to the sense entry. For example, in this case &#34;issue&#34; used as an intransitive verb would favor &#34;passive moving&#34; even though it is a secondary sense, while the io-rec subcategorization in the first two senses means that the ditransitive form will fill the recipient conceptual role. The grammatical knowledge base of the system relates these subcategories to semantic roles. 
     The :G-DERIV and :S-DERIV fields mark morphological derivations. G-DERIV (NIL in this case to indicate no derivations) encodes these derivations at the entry, or word, level, while S-DERIV encodes derivations at the sense level. Each S-DERIV derivation entry can be marked as preferred or unpreferred. For example, the S-DERIV constraint allows &#34;issuance&#34; to derive from either of the first two senses of the verb, with &#34;issuer&#34; and &#34;issuable&#34; deriving only from the &#34;giving&#34; sense. 
     The derivation triples (such as (-er noun tr --  actor)) encode the form of each affix, the resulting syntactic category (usually redundant), and the &#34;semantic transformations&#34; that apply between the core sense and the resulting senses. For example, the &#34;issuer&#34; in this case would play the actor role of sense one of the verb issue. Because derivations often apply to multiple senses and often result in different semantic transformations (for example, the ending -ion can indicate the act of performing some action, the object of the action, or the result of the action), the lexicon often contains strongly &#34;preferred&#34; interpretations to help control the ambiguity. 
     The lexicon may also include a substantial number of common collocations, such as verb-particle and verb-complement combinations. These expressions are often semantically productive, but the representation of common expressions helps the semantic interpreter to apply preferences. For example, the following is one set of entries for expressions with take:

 The above entries contain only the verb-complement (vc) relations for
 &#34;take&#34;. Whether these expressions are productive or not, the lexicon can
 include explicit word sense pairings (such as take 52 with noun .sub.--
 pressure 2), in which case the collocation helps to discriminate the
 senses of both verb and complement, or a pairing with a conceptual
 category (such as take 51 with c-temporal-obj), in which case the pairing
 is more likely to conflict with another but will cover a much broader
 class of expressions (from take one&#39;s time to take years).
