PROBLEM TO BE SOLVED: To obtain a more appropriate text by selecting an appropriate retrieval word to be added to a retrieval expression to present it to a user with respect to the retrieval result obtained when the user designates a certain retrieval condition and then adding the retrieval word selected by the user to the retrieval expression for execution of the reretrieval. ;SOLUTION: A selection means 1 selects an appropriate retrieval word to be added to a retrieval expression with respect to the retrieval result obtained when a user designates a certain retrieval condition. An additional retrieval word presenting means 2 presents the retrieval word selected by the means 1 to a user. An adding means 3 adds the retrieval word that is selected by the user to the retrieval expression among those retrieval words which are presented by the means 2. Then a reretrieval means 4 performs the retrieval again by means of the retrieval expression to which the selected retrieval word is added. In such a method, a more appropriate text can be obtained and the user can acquire his really necessary information in a shorter time and an easier way.;COPYRIGHT: (C)1999,JPO
