Estimation of Factor Scores of Impressions of Question and Answer Statements

To eliminate mismatches between the intentions of questioners and respondents, we have conducted impression evaluation experiment and nine factors are obtained. Factor scores of the statements used in the experiments are obtained. Those of other statements, however, cannot be obtained. This paper proposes a method of estimating the factor scores of other statements through multiple regression analysis applied to those feature values of statements. Syntactic information of statements, word imageability, closing sentence expressions, word familiarity and notation validity are adopted as feature values of statements. It is shown that overall estimation accuracy is very good for all the factors. This research uses the data of “Yahoo! Chiebukuro” given to National Institute of Informatics by Yahoo Japan Corporation. Estimation of Factor Scores of Impressions of Question and Answer Statements
