Optimal query generation device, optimal query extraction method, and discriminant model learning method

摘要

Provided is an optimal query generation device capable of generating an optimal query to which domain knowledge should be added when generating a discriminant model that reflects knowledge of a user model and domain knowledge indicating an intention of analysis. The query candidate storage means 86 stores a query candidate that is a target model to which domain knowledge indicating the user's intention is to be given. The optimal query extraction unit 87 extracts, from the query candidates, a query in which the uncertainty of the discriminant model estimated using the query to which the domain knowledge is given becomes small when the domain knowledge is given.
