Scenario generation apparatus, scenario generation method, and computer-readablerecording medium

A scenario generation method comprising:

• extracting a hierarchical structure from documents that is a basis of a scenarios for use in chatbot and has the hierarchical structure, and selecting keywords from the headings in each layer of the extracted hierarchical structure,
• generating a first scenario candidate in which a link is set between the keywords and a second scenario candidate in which a link is not set between the keywords, by using documents,
• calculating an evaluation value for the link for each of the generated first scenario candidate and the second scenario candidate according to a setting rule,
• adopting one of the scenario candidates based on the calculated evaluation value and generating the scenario using the adopted scenario candidate.
