Title: Information retrieval device
Inventor: UEDA TORU
IPC: G06F17/30
Filed: 1994-04-22
Abstract: PURPOSE:To omit a waste such that the user observes a retrieval result of the same content for plural number of times by deleting other results while leaving only one result among same content results when results of the same contents are included in results of plural retrieval acts. CONSTITUTION:A receiver terminal equipment uses a retrieval section 4 to make retrieval in response to a retrieval request entry, the retrieval result is stored tentatively in a retrieval result buffer 5, and the reception terminal equipment sends the retrieval result to a sender terminal equipment via a network section 2. The sender terminal equipment uses a duplication delete section 6 to check whether or not results of same contents are included among plural retrieval results and deletes other results while leaving one result of the same contents when the same results are included in them. Thus, the retrieval results of duplicate contents are not outputted, and then waste of the user observing the retrieval results of same contents for plural number of times is avoided.
