摘要

We execute retrieval of words or phrases for avariety of purposes making use of retrieval systems. A word in a sentence， generally has the function(s) which can be defined in relation to other elements of the sentence. In this paper we wiI1 refer to this sort of function as grammatical function of word. And sometimes it is the case that a word can fulfill different functions in different sentences. Thus the word "there" is used either a.s a. deictic locative adverb or as an expletive element. The problem for a retrieval system is the following: when we are in search of expletive "there"，sentences， for example， the sentences containing locative "there" are irrelevant. It is necessary to decrease the number of these unexpected sentences in the result of retrieval， possibly up to zero. We have attempted to incorporate this feature into the retrieval system for the database ca.lled English Corpus by making use of grammatical function of word. This paper is a preliminary discussion of a prototype retrieval system applied to the English textbooks used at Japanese junior high schools.
