<P>PROBLEM TO BE SOLVED: To provide a query generation device which can generate a query having versatility. <P>SOLUTION: As representative paths have increased in number, the number of queries relevant to a group G13 has increased to a threshold value (1, for example) or more. Thus, when the numbers of queries for all groups have become equal to or higher than the threshold value, queries consisting solely of combined representative paths are retrieved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
