Further Tendency of Obtaining Potential Appropriate Respondents to Questions at Q&A Sites through Additional Categories

Abstract

In order to eliminate mismatches between the intentions of questioners and respondents of Question and Answer (Q&A) sites, nine factors of impressions for statements have experimentally been obtained. Factor scores are then estimated by using the feature values of statements. So far the possibility of searching respondents capable of giving appropriate answers to a newly posted question has been established for Auction, PC and Love. It has been shown that the distance and the number of appearance may help us select users who can give appropriate answers to a question. In the similar fashion, this paper tries to find the possibility of detecting respondents who can appropriately answer a newly posted question for other categories such as Internet, Politics, etc. As a result of analysis, several newly regarded categories shows the similar tendency as the previous analysis, while some categories related to Yahoo! JAPAN show less outstanding tendency.
