On a Retrieval Support System by Suggesting Terms to a User.
Hiroyuki Sakai, Kiyonori Ohtake, Shigeru Masuyama · 2001
We propose a support method for information retrieval. This method automatically suggests terms, which are relevant to a query, to a user, and when the user can not select adequate terms from among the suggested terms, the method suggests new terms contained in retrieved documents. We implemented an information retrieval system based on our support method and evaluated it by having users fill out a questionnaire. From the results of evaluation experiments, we consider that this system is useful for users who have insufficient knowledge about the fields concerned.
