<P>PROBLEM TO BE SOLVED: To efficiently select an appropriate retrieval result by differentiating the superiority of retrieval results in a case where a plurality of retrieval results are acquired, whose consistency degrees to a retrieval condition are the same in retrieval processing using a database. <P>SOLUTION: A retrieval result output device detects, at a time of completing retrieval of attribute information storage tables storing attribute information consistent with a retrieval condition, upper nodes without duplication, positioned upper by one layer than nodes corresponding to the attribute information storage tables storing the attribute information consistent with the retrieval condition, counts, for each of the upper nodes, the number of nodes corresponding to the attribute information storage tables storing the attribute information consistent with the retrieval condition among lower nodes positioned lower by one layer than the detected upper nodes, rearranges the order of the upper nodes in the descending order based on the number of the counted lower nodes, and outputs the retrieval result according to the order. <P>COPYRIGHT: (C)2013,JPO&INPIT |
