Over the past few years, a considerable number of studies have been done on help systems, which support users by effectively presenting information necessary to use the application software. However, most of studies have the following problems:
(1) It is difficult to deal with context-dependent knowledge.
(2) If a help system fails recognition of user intention, incorrect processing in the help system is carried out.
This paper proposes an intelligent help system to realize a smooth communication between a user and an application software by repeating recognition of the user intention and visualization of system's status. The proposed help system consists of the following parts:
(i) the input part that gets user words.
(ii) the intention-recognition part that recognizes the user intention from the user words.
(iii) the visualization part that intuitively visualizes the user intention and corresponding operation method of the application system to the users.
This paper applies the intelligent help system to the drawing tool and shows that the intelligent help system resolves the above problems. The intelligent help system recognizes user intention when user words are given and visualizes the user intention and the corresponding operation method even if the user does not know the operation method desired to realize one's intention.
