Quantitative Evaluation to Investigate Further Tendency of Obtaining Potential Appropriate Respondents to Questions at Q&A Sites

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 have been then estimated by using the feature values of statements. So far the possibility of detecting respondents who can appropriately answer a newly posted question has been established for several categories e.g. Auction, PC, etc. It has been shown that the distance and the number of appearance could lead to selecting users who are able to appropriately answer a question. In order to inspect these tendencies, this paper tries to find the possibility of detecting appropriate respondents by adding respective eight question statements for each of the nine categories. As a result of analysis, the tendencies that particular several users are apt to appear in each category has been verified. Meanwhile, several different outstanding tendencies have been also observed.
