Users of Social Network Services(SNS) can sometimes enter into heated discussions, which prompt those users to concentrate on a single issue and lose track of the actual theme. We believe that it would be beneficial for users and visitors to present information to help understand the gist of the discussion at a glance. As described in this paper, we propose a system that presents a gist of a thread on an SNS and basic information about it by comparing the comments in the thread with Wikipedia article. Wikipedia articles, however, are not always credible. When we compare a thread on an SNS with Wikipedia, the Wikipeida article must have credible content. We measure the credibility of the article based on the credibility of Editors. We first extract the target passage which is candidate of the gist of a thread in an SNS based on the Wikipedia Table of Contents(TOC). Then we measure the credibility of editors of Wikipedia using the edit history and measure the credibility of the article using results of the credibility of editors. The target passage, which has a high similarity degree with comment in an SNS and has a high credibility rate becomes the gist of the thread in SNS. Consequently, users and viewers can ascertain the gist of an SNS thread by viewing a Wikipedia TOC with credibility.
