Abstract
Recently, commercial software products often incorporate OSS. Industrial developers often need to know plans of enhancement and bug fix for a specific feature of OSS when they should determine whether or not to incorporate it. However, it is difficult for outsiders to retrieve a person familiar with a specific feature in OSS due to the voluntary nature of the contributions. In this paper, we present a tool for visualizing version archives to support industrial developers who find OSS developers familiar with a specific feature. This tool applies topic analysis to version archives for characterizing activities of individual developer.
