SENSE DATABASE

There has been conventionally a problem that when the searcher uses, for example, "dry wine" selected according to the searcher's preference as a search key, the searcher cannot be satisfied with the search result because wine entries stored in a database as "dry wines" depend on objective evaluation by another person. A sense database is created by using, as a subjective search index, sense parameter information such as potential variation caused by pungency obtained by a pseudo sensor irrespective of one's ability. Specifically the database comprises a sense information obtaining section for obtaining sense information by associating the sense parameter information acquired by the sensor with representative information, a sense information storage section, a search key obtaining section, and a searching section for searching the sense information storage section using a search key.
