| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | By the development of the information system, recording the log of the learning situation and the examination result has increased. We think that we will be able to offer other learner useful knowledge by extracting learning patterns from these log data. However, raw learning log data is unsuitable for extracting pattern that expresses relation of each learner, because the learning log data is often stored in the database. In this paper, we transform learning log data from time-series data into digraph structure (each learnings is node, and sequence of learning is link). And we purpose to find a characteristic learning trend in same cluster by clustering with many subgraph in these digraph. | |
