本文首先对问答网站的问答印象进行评价，以避免问答者与被问答者之间的错配问题。从词典中选取了50个能有效评价令人印象深刻的语句表达的单词。然后，对发布在Yahoo！上的60个问题和答案进行了令人印象深刻的评估实验通过使用那些印象中的词语来实现。对实验得到的分数进行因子分析，得到9个因子。然后尝试使用多元回归分析来估计任何其他陈述的因子得分。然而，这一结果表明，估计精度不够。为了提高估计精度，采用了考虑二次项的多元回归分析。分析结果表明，该方法可以提高估计精度。
First, this paper evaluates the impression of questions and answers at Questions and Answers (Q & A) sites in order to avoid the problem of mismatch between the questioner and the respondent. Fifty impression words effective in evaluating impressive expression of statements are selected from a dictionary. An impressive evaluation experiment is then conducted for sixty questions and answers posted at Yahoo! Chiebukuro by using those impression words. Nine factors are obtained by applying factor analysis to the scores obtained through the experiment. Then factor scores of any other statements are tried to be estimated by using multiple regression analysis. This result, however, shows that the estimation accuracy is insufficient. To improve the estimation accuracy, the multiple regression analysis considering quadratic terms is applied. The result of the analysis shows that the estimation accuracy can be improved.
