摘要：This paper discusses time expressions as clues to understand a user's intention. We employed three questionnaires to find relationships between hearers' guesses on semantically ambiguous phrases and time expressions in them. The results showed that the questionnaires' respondents tended to change their guess corresponding to the granularity of the time expression in the phrase, and that this tendency is common, regardless of age or sex. The results also showed that almost all of the guesses could be classified into three categories: speaker's attribute, current state, and purpose or reason for action. Therefore, we concluded that it is effective to focus time expressions to clarify ambiguous utterances and understand intention.
