1. A method of generating, on a computer readable recording medium, a data structure representing a topic net for generating dialog information, the data structure including a plurality of nodes associated with topics and a plurality of links connecting the nodes, comprising:

  • causing execution of operations by a computer processor including;

    reading from a computer readable recording medium one record from a data table including a plurality of records, each record including field data associated with a plurality of fields;

    storing in the computer readable recording medium topic classes, associations between the topic classes and the plurality of fields of the read record, and associations between each of the topic classes, respectively;

    storing in the computer readable recording medium templates having fields embeddable with field data and the template fields associated with the stored topic classes respectively;

    generating nodes with respect to the fields associated with the field data included in the read record, the fields associated with any one of the stored topic classes, by;

    specifying a plurality of nodes corresponding to one topic based upon the field data in the read record, andstopping generation of duplicate nodes by not generating a node having a topic same as a node specified in the specifying of the plurality of nodes;

    generating topics corresponding to said generated nodes and storing the generated topic classes;

    linking each of the nodes generated in accordance with the stored associations between each of the topic classes; and

    generating dialog information by completing the blank fields in a template with the field data in the read record, wherein the fields associated with the field data of the read record and the blank fields correspond to same topic classes respectively and the fields are associated with any one of the stored topic classes including the generated topic classes.
