Abstract: The discussion record in collaborative learning where participants generate their own answers by exchanging their opinions through a discussion is useful for other learners who tackle the same exercise. We propose a method for organizing solution knowledge in collaborative learning records as a solution knowledge graph which is a structured knowledge to derive answers. In this method, utterance collections of the same answering method are extracted and structured from the viewpoint of their effectiveness based on annotations attached by the participants. In addition, the structure of the solution knowledge graph is refined by evaluation of learners who use it as knowledge to solve exercises. We have constructed the prototype system for utilizing the solution knowledge graph in individual learning. From the experimental result, our system was reorganizing the solution knowledge graph according to the effectiveness of the utterance collections.
