Document content analysis and abridging apparatus

摘要

A requirement acquisition system for grasping requirements from related documents such as documents the client holds, investigation results of an interview or questionnaire, meeting minutes, specification and the like, in system or software development, by reduced efforts and hours is provided. In particular, from a document being a group of character strings, one or more partial string which is a common part of the plurality of character strings is extracted as an important phrase. When the important phrase does not exist, the processing is finished. When the important phrase exists, a representative character string of the document is extracted as a candidate character string, deleting the candidate character string is deleted from the document, and the important phrase is deleted from the candidate character string. When the number of the important phrase being deleted is one or more, the candidate character string is set as an important character string.
