DEVICE, METHOD, AND PROGRAM FOR RECOMMENDING RETRIEVAL CONDITION

摘要

PROBLEM TO BE SOLVED: To suppress recommendation of similar retrieval conditions and support user's retrieval action. SOLUTION: A retrieval condition recommendation device is equipped with: a log obtaining part 100 which obtains a combination of a user specified retrieval condition and a URL of a browsing document retrieved by the condition as a log; a log processing part 101 which computes an appearance frequency for each pair of retrieval condition URL from the log; a retrieval condition URL pair obtaining part 102 which obtains the pair relevant to user specified processing object retrieval condition from a computing result; a graph making part 103 which prepares a bipartite graph based on the retrieval condition URL pair information; a relevance determination part 104 which determines relevance of the processing object retrieval condition and the other retrieval conditions based on the bipartite graph; a graph dividing part 105 which divides the bipartite graph; a recommending query selection part 106 which selects the recommending query, based on the determined relevance and the dividing information; and a recommending candidate presenting part 107 which obtains the recommending query corresponding to the retrieval condition specified by the user, and presents it to the user.
