- On the Internet, the users of Question and Answer (Q&A) sites rapidly increase. With more users, however, the mismatch of questioners and respondents arises. It is required to introduce a question to the users who could appropriately answer it. A number of prior works have tackled the issues arising on Q&A sites. To the best of our knowledge, however, the way of introducing appropriate respondents to questioners has not been established yet. The objective of this research is to present questions to qualified users who can appropriately answer them. Firstly, in order to be able to judge the affinity of a questioner and a respondent, the impressions of 60 questioners and their responses posted at Yahoo! Chiebukuro are experimentally evaluated. By applying factor analysis to the scores of the experiment, it is clarified that the impression of the statements could be captured by nine factors. Factor scores are then estimated by using the features including syntactic information, word imageability, closing sentence expressions, word familiarity, and notation validity. With the consideration of quadratic terms and multicollinearity, the good overall estimation accuracy has been obtained. The method of introducing appropriate respondents to questioners is proposed. The proposed method uses the number of appearance of respondents and the score based on the distance between the factor scores of a question and an answer already posted. Impression evaluation experiment is carried out in order to evaluate the proposed method. The proposed method is compared with the methods using averaged scores and the distances. It is shown that the proposed method outperforms the other methods. It is also shown that the proposed method could successfully select the respondents that are almost more than averagely appropriate to a question.
