Method and system of retrieving program specification and linking the specification by concept to retrieval request for reusing program parts

摘要

Herein discolosed is a software information reusing system comprising: a data base for storing software information; a dialogue display terminal; thereby processing the information inputted from the display terminal. First retrieval information of the software information is registered as data related with a link of a data information related concept. If second retrieval information is not in the registered data, it is judged on the basis of the link of the related concept whether or not third retrieval information related therewith exists. The data base is retrieved on the basis of the third retrieval information. As a result, it is possible: to form a dictionary data base including a noun dictionary and a synonym dictionary for analyzing and generalizing the data object of the specification to be newly registered; for a user unacquainted with the business knowledge to automatically extract a proper retrieval keyword from a retrieval request sentence describing the software coming into the mind of the user; and to judge from the relations between the keyword information and the before and behind words whether or not even a composed word left either unregistered as one word or unknown is the retrieval keyword, if even one of elements composing the composed word is found to have the corresponding keyword information.
