PROGRAM, INFORMATION RETRIEVAL METHOD, PROGRAM STORAGE MEDIUM, INFORMATION RETRIEVAL SYSTEM, AND INFORMATION PROCESSOR

PROBLEM TO BE SOLVED: To provide a highly versatile information retrieval method or the like. SOLUTION: This program is provided with steps of: retrieving an input retrieval object input as a destination by a retrieval engine, and acquiring the retrieval result; extracting destination information from the retrieval result; ranking the destination information; and outputting the destination ranked high, wherein a computer retrieves the destination information from the destination. Thus, it is possible to acquire destination information without depending on any special database by acquiring the destination information from the retrieval engine. And, in the other method, retrieval is performed in two stages through clue information, so that even when it is not possible to directly acquire desired candidate information from the retrieval object, it may be possible to acquire the desired candidate information from the clue information. Thus, it is possible to extremely improve retrieval precision. COPYRIGHT: (C)2009,JPO&INPIT
