    1. System for processing natural language including identifying grammatical rule and semantic concept of an undefined word

      A natural language including Japanese, Korean, Chinese, etc., is suitably processed when an undefined word which is not registered in a dictionary appears in an input character train. When the undefined word appears, a semantic analysis processor decides a semantic concept of the undefined word by using a case dictionary. Further, by using a vocabulary hierarchy dictionary, which registers vocabularies in a hierarchy structure, the semantic analysis processor extracts a group of vocabularies (synonyms) corresponding to a lower concept of the semantic concept of the undefined word. The natural language processing can be achieved practically and efficiently with dictionaries of ...

    2. Natural language processing system

      A natural language arrangement includes stored grammatical rules each having a phrase structure part representing grammatical functions, a semantic part representing the manner of propagation from a superordinate category to a subordinate category, a condition part, and a message part that imposes limitations on a phrase structure rule using the subordinate category as a superordinate category. The grammatical rules are searched and interpreted to generate a phrase structure for a sentence from grammatical function information obtained by interpreting and applying the searched grammatical rules.

    3. System and method for parsing natural language by unifying lexical features of words

      A method for parsing for natural languages includes a grammar and a lexicon. A knowledge base may be used to define elements in the lexicon. A processor receives single words input by a user and adds them to a sentence under construction. Valid next words are predicted after each received input word. The preferred system has two major components: a parser and a predictor. The predictor accesses only the lexicon and the knowledge base, if one is used, to determine the valid next input words. The parser constructs sentences which are valid according to the grammar out of words accepted ...

    4. Method of recognizing continuously spoken words

      A method of recognizing continuously spoken words in which, during the speech recognition, speech values derived from the speech signal are compared with comparison values of the individual words of a given vocabulary. In order to reduce the rate of recognition errors, it is essentially known to take into account speech models, which consequently admit only selected sequences of words. From the theory of the formal languages, a class of speech models designated as "context-free grammar" is known, which represents a comparatively flexible speech model. For the use of this speech model in the technical process of recognition of a ...

    9. Character string identification device with a memory comprising selectively accessible memory areas

      In a character identification device for identifying an input character to produce an identified code, a memory circuit (40) decides a match between the input character and stored characters preliminarily stored therein to produce a character match signal. An encoder (50) encodes the character match signal into the identified code. The memory circuit (40) includes a plurality of memory areas (41 to 44). A memory area selector (54) selects a specific memory area in response to a selection signal produced from a signal producing circuit (52) to supply the input character to the specific memory area. In a character string ...

    10. Process for the recognition of a continuous flow of spoken words

      Continuous speech recognition assigns predetermined words to syntactic categories and defines the syntactic categories which can follow and precede each predetermined word. The recognition process is achieved by comparing the input sequence of speech signals to reference values and summing those which are syntactically permissible until they form a valid word. Subsequent speech values to previouly calculated valid words are compared to reference values listed in syntactic categories which can follow the predetermined word. For each word, values are updated indicating the current word's sequence number, syntax category, cumulative comparison sum, and the current list of compared words. Values ...

    11. Method and system for generating lexicon of cooccurrence relations in natural language

      A method and an apparatus for generating/maintaining automatically or interactively a lexicon for storing information of cooccurrence relations utilized for determining whether or not a sequence of words in a given sentence described in a natural language is semantically correct with the aid of a memory, a data processor and a textual sentence file. A hypothesized cooccurrence relation table for storing hypothesized cooccurrence relations each having a high probabliity of being a valid cooccurrence relation is prepared by consulting the file. A hypothesis for the cooccurrence relation is previously established on the basis of a cooccurrence relation pattern indicating ...
