| Outline of Final Research Achievements |
This research proposed some methods of constructing potential research clusters using an institutional repository, which is an online archiving system for publications authored by members of an institution, and a type of topic model (the author topic model) based on latent Dirichlet allocation. These methods estimate the research topics of authors using whole sentences in their papers. Then, to construct research clusters, they link these authors on the basis of their main topics or subtopics or via the other papers as pivot topics. Some of the experiments conducted in this research were successful in obtaining networks of researchers using the institutional repository of Kyushu University as a practical case.
