    10. Method and apparatus for classifying text

      The present invention provides a method and apparatus for classifying text by using two constants determined by analyzing the text. The first constant, G, classifies text in the order of constraint. It is defined by the equation G=log (N/L)/ {log(N)-1}, where N is the number of words and L is the number of different words in the text being classified. The second constant, R, is the correlation coefficient between the word length and the logarithm scaled rank order of word frequency. The values of the two constants can be used to determine how to classify text ...

The data structure can be a tree in which each node has a textual type such as a paragraph, sentence, clause, phrase, or word. The data structure could alternatively be parallel data sequences, one with codes indicating the text's characters and ...

    16. 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 ...

    18. 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 ...

    19. 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 ...
