Providing Help and Advice in Task Oriented Systems

摘要

The WIZARD Help system has addressed only ihe problem of recognizing certain situations in which the user may need help or advice. Our current work is directed toward developing better approaches to modeling the individual user (i.e. his interests, level of expertise, etc.), the generic user (i.e. his a priori goals, his planning stategies, etc) and toward making the interaction between the user and help system more of a dialog. In particular, we have been working on recognizing and responding to a user's misunderstandings |Schuster 83], using a model of the user as a basis for customizing the help offered [Schuster 83] and various spreading activation techniques for identifying relevant help information from a set of weighted keywords |Howe 83].
