METHOD FOR SYNTAX ANALYSIS IN NATURAL LANGUAGE PROCESSOR

摘要

PURPOSE:To restrain a part of speech immediately after a predicate and to improve the accuracy of syntax analysis by writing the name of a part of speech restrained immediately after the predicate in the argument of the predicate. CONSTITUTION:An input sentence supplying device in a natural language processor 1 segments sentences supplied from a data input means into pieces of sentence based upon data indicating a punctuation mark or period and a morpheme analysis executing part divides each segmented input sentence into words and morphemes each of which is smaller than each word and sends these words and morphemes to a syntax analysis part, which executes the syntax analysis of each input sentence and sends the data of tree structure obtained as the result of syntax analysis to a semantic analysis part. Thus a part 2 obtained by writing the name of a part of speech restrained immediately after a predicate in the argument of the predicate during the notation of a difinitive clause grammar is connected to the processor 1. The name of the part of speech can be restrained by writing the name of the part of speech in the argument of the predicate.
