PROBLEM TO BE SOLVED: To retrieve the contents of an ambiguous impression by an interactive format. SOLUTION: A retrieving processor judges whether a retrieving query is inputted or not in a step S42, and at the time of judging the input of the retrieving query, acquires the inputted retrieving queries, calculates the similarity of the queries, and, deletes the queries whose similarity is not more than a prescribed value from a candidate list in steps S43 to S45. At the time of judging no input of the retrieving query, the processor judges the number of contents in the candidate list is not less than a prescribed number or not in a step S46, and when the number of contents is not less than the prescribed number, outputs an additional query to a user in a step S47. |
