A topic net management unit 1 reads one record from a table to generate the topic net (S1). Subsequently, from among the field data in the record, the unit 1 generates nodes corresponding to the field data for which a corresponding topic class exists (S2). Topics corresponding to those nodes are generated. If a node having the same topic is already generated, then the unit 1 does not newly generate a node having a duplicate topic (S2). The unit 1 mutually links the generated topics in accordance with the definitions between the topic classes (S3). Further, using a dialog information template, the unit 1 generates dialog information associated with the generated link (S4). The unit 1 performs Steps S1-S4 processing for all records in the table (S5). If there is a plurality of tables Steps S1-S5 processing is performed for all tables (S6).
