Counseling Dialog System with 5W1H Extraction

In this paper, we introduce our counseling dialog system. Our system interacts with users by recognizing what the users say, predicting the context, and following the users‟ feelings. For this interaction, our system follows three basic counseling techniques: paraphrasing, asking open questions, and reflecting feelings. To follow counseling techniques, we extracted 5W1H information and user emotions from user utterances, and we generated system utterances while using the counseling techniques. We used the conditional random field algorithm to extract 5W1H information, and constructed our counseling algorithm using a dialog strategy that was based on counseling techniques. A total of 16 adults tested our system and rated it with a higher score as an interactive communicator compared with the baseline system.
