A topic net management unit 1 reads one record portion of data from a collection of data in table format (S 1 ). Subsequently, from among the field data included in the record that was read, the topic net management unit 1 generates, based on the definitions of the topic classes, nodes corresponding to the field data for which a corresponding topic class exists (S 2 ). In addition, topics corresponding to those nodes are generated. If a node having the same topic is already generated, then the topic net management unit 1 does not newly generate a node having a duplicate topic (S 2 ). The topic net management unit 1 mutually links the generated topics in accordance with the definitions between the topic classes (S 3 ). Further, using a dialog information template, the topic net management unit 1 generates dialog information associated with the generated link (S 4 ). The topic net management unit 1 performs Steps S 1 -S 4 processing for all records included in the data in table format (S 5 ). If there is a plurality of tables to generate the topic net, then the topic net management unit 1 performs Steps S 1 -S 5 processing for all tables (S 6 ).
