PROBLEM TO BE SOLVED: To set the destination of path finding while paying no attention to operation for inputting the destination.SOLUTION: A destination conjecture device 100 includes: a retrieval list acquisition section 110 for acquiring retrieval information including information on a retrieval term retrieved in a retrieval site 300; a retrieval term attribution granting section 132 for granting attribution information representing attribution of the retrieval term to a retrieval term; a retrieval term evaluation section 133 for obtaining frequency of appearance of a retrieval term whose attribution is in common for each attribution; and a conjecture destination candidate extraction section 134 for extracting a retrieval term related to a destination among retrieval terms included in attribution whose frequency of appearance satisfies a predetermined criterion as a conjecture destination candidate.SELECTED DRAWING: Figure 1
