The authors are developing a computer-based consultant system. A user can verbally ask this system for help when problems occur. The system understands the user's utterances and then makes appropriate responses. Our target language is spoken Japanese.

To develop such a consultant system, recognizing communicative intention (CI) from a user's utterance is essential. CI recognition consists of two parts, i.e., speech and natural-language processing. In this paper, the latter is focused on and we propose a method of constructing a CI description from a sentence transcribed from the user's utterance.

Our approach is based on an analysis of actual user utterances. These utterances were collected in XMH (X-window-based electronic mail handling program) [2] usage experiments. XMH has a visual interface operated using a mouse and a keyboard. Using this XMH, 16 novice XMH users performed a given task, e.g., arranging a tea party. They asked a human consultant for help when they were in trouble and the consultant helped them solve the problem. Based on our analysis of these user utterances, a description form of CI is defined and the CI recognition method is developed by which a CI description is constructed from a sentence.
