Predicate function expression normalization method, apparatus and program thereof

摘要

PPROBLEM TO BE SOLVED: To convert a predicate as the center of sentence information in natural language processing into the simplest form without changing the meaning as much as possible. PSOLUTION: With respect to the word information of each morpheme corresponding to the predicate of an input sentence analyzed by a morphemic analysis part 2, and extracted by a predicate extraction part 3, a meaning label application part 4 applies a meaning label to the word information of a function word string configuring functional expression by using a functional expression meaning label dictionary 1 configured by combining at least a meaning label expressing the meaning of functional expression giving an influence to the meaning of the predicate and the list of the functional expression corresponding to each meaning label, and an NULL deletion part 5 and a redundant rule application part 6 delete a function word and a redundant function word which do not give any influence to the meaning of the predicate according to the pertinent meaning label, and a practical use generation part 7 generates the predicate of the input sentence based on the word information of each morpheme corresponding to the residual predicate of the input sentence.
