<p>PROBLEM TO BE SOLVED: To obtain a retrieval system which is capable of continuous input and storage of plural retrieval conditions and of retrieval even for a set combination. SOLUTION: A fixed-form input picture is presented by a retrieval condition input part 10 to allow a user to successively input retrieval conditions. Retrieval conditions are temporarily stored by a retrieval condition collection part 20. An external information source 80 is used to execute retrieval in stored retrieval conditions by a retrieval part 30 provided with a retrieval agent 31. Knowledge processing is executed in the retrieval processing by a knowledge processing part 40, and required postprocessing is performed by a retrieval result processing part 50. If re-retrieval processing is necessary, condition re-input is supported by a condition re-input prompting part 51.</p> |
