Abstract
We developed a computational system to flexibly judge whether the misuse of honorifics are included in Japanese speech sentences. The proposed system is a practical approach to assist in education. The system uses judgment rules that were constructed in the present study by improving rules proposed in a previous study. Specifically, rules with a degree of validity beyond the thresholds determined by users were used for the judgment. The degrees of validity of rules were quantified by psychological experiments involving subjects who are not experts in Japanese linguistics.
Our research is useful because (i) the proposed system can urge users to learn normative rules which have higher validity (i.e., the importance of learning) prior to other rules, where excessively strict judgments are avoided by determining the thresholds appropriately; and (ii) rules with degrees of validity are useful quantitative data for researching and teaching honorific Japanese linguistics.
