Abstract
In these days the online full-text databases are increasing, but these full-text databases are difficult to retrieve, because recall is high er than bibliographic databases, and precision is so lower. There are cases where we don't always read whole paper, but use one or a few par t of an article. So this paper presents an approach to retrieve the re levant parts of a document by using paragraphs of individual documents . Sample documents are 49 articles in Japanese about information retri eval and natural language processing studies. The retrieval technique used in this retrieve experiment is the vector space model. As a resul t, the higher precision and recall were shown by using the words in ch apter titles or section headings to retrieve the relevant paragraphs.
