Abstract
A semantic description storing means stores semantic descriptions representative of meanings of respective document components. A semantic description designating means designates one of the semantic descriptions stored in the semantic description storing means. A schema storage means stores, in a correlated manner, a schema and the designated semantic description of a document component of the schema. A document retrieving means performs retrieval on a database by using the semantic description thus stored in the schema storage means. A retrieval formula conversion means causes the schema retrieving means to call the correspondence between the semantic description and the schema from the schema storage means, receives a first retrieval formula relating to a first schema and directed to first retrieval, and converts the first retrieval formula to a second retrieval formula relating to a second schema and directed to second retrieval that is equivalent to the first retrieval.
