In an information processing apparatus, a SurfaceRule table having surface-layer information, a ConceptRule table having conceptual information, a connection table for correlating the two tables, and a retrieval table storing an ID of a connection table corresponding to a character string are provided in a conceptual database. A conceptual instance corresponding to an input character string is formed by retrieving a retrieval table using the input character string, referring to a connection table using an obtained ID of the connection table, and acquiring information, such as a concept, a part of speech, a tense, a slot and the like, from fields of corresponding SurfaceRule table and ConceptRule table.
