Many learning techniques of Bayesian network have been developed for adaptation to user or environment. However, it seems several drawbacks still exists in conventional learning approach; the hardness of collecting log data, the inherent ambiguity in recognizing and reflecting implicit user's intention, and difficulties in extracting relations between data or definite rules. In this paper, we propose a method for parameter learning in Bayesian network using semantic constraints of conversational feedback to overcome these limitations. Production rules extracted from users' conversational feedback are used in parameter learning of Bayesian network. A comparison test with conventional approaches in conducted to verify the usefulness of the proposed method.
