Papers on Proactive Dialogue

Abstract: This paper describes our analysis of the literature on tutorial dialogues and presents a compilation of useful principles that students and teachers follow in making tutoring interactions successful. The compilation is done in the context of making use of those principles in building interactive acquisition interfaces since acquisition interfaces can be seen as students acquiring knowledge from the user. We plan to use these ideas in our future work to develop more proactive and effective acquisition interfaces.

Abstract: This paper argues that interactive knowledge acquisition tools would benefit from a tighter and more thorough incorporation of tutoring and learning principles. Current systems learn from users in a very passive and disengaged manner, and could be designed to incorporate the proactive capabilities that one expects of a good student. This paper points out what tutoring and learning principles have been used to date in the acquisition literature, though unintentionally and implicitly. We discuss how a more thorough and explicit representation of these principles would help improve enormously how computers learn from users.

Abstract: Current tools for interactive knowledge capture have little or no learning aptitude. They are mostly oblivious to the process or strategy that the user may be following in entering new knowledge, unaware of their progress during a session, and ignorant of typical skills expected from a good student. User has to make up for these shortcomings by tracking the status, progress, potential problems, and possible courses of action themselves. We present an approach to make acquisition interfaces more proactive by extending them with: 1) goals that represent what remains to be learned, 2) strategies to achieve these goals and acquire further knowledge, and 3) awareness of the current status of the body of knowledge learned. The resulting interaction shows that the system is aware of its progress towards acquiring the new knowledge, and moves forward by understanding what acquisition goals and strategies to pursue.
