In order to construct effective writing support methods, we attempted to visualize the language sense in written language. First, by analyzing readers’ comments on sample sentences, we were able to extract “sentence arrangement,” “word meaning,” “context,” and “word arrangement” as elements of the sense of “appropriateness” of language. Next, we developed the tool to visualize the tendency of readers to distinguish between opinions and facts, and confirmed the effectiveness of the tool. Finally, by analyzing the tendency of multiple people’ s corrections to the sample sentences, we were able to show the possibility of reflecting their sense of the appropriateness of the language.
