In online community-type content such as SNSs and blogs, users occasionally do not understand the theme of the content from multiple viewpoints, and much of the information is often lost. Because the discussion in a community is concentrated, the viewpoint narrows. We believe that it is necessary to provide information about the lack of awareness of a user to the users of community-type content. Information about which a user is unaware is called as a "content hole," and searching for such holes is called as "content hole search." In this paper, as a first step toward developing a technique for searching for content holes, we attempt to extract and represent important but neglected content from online community-type content based on isolated and non-related degrees. This content is information that nobody from the community is interested in, but that may be of interest to many people outside the community.
