ARTIFICIAL INTELLIGENCE SEMINAR
- Friday, January 20, 1989
Mr. Brad Goodman, BBN Systems and Technologies
Corporation, Cambridge, Massachusetts, will speak on
``Plan Recognition for Intelligent Interfaces''.
TIME: 1:30 PM
ROOM: DC 1304
ABSTRACT
Plan recognition is an active research area in
automatic reasoning, as well as a promising approach to
engineering better interfaces in a wide variety of
application areas. However, exactly what kind of tasks
plan recognition can be used to support, and how such
tasks in turn constrain plan recognition algorithms,
are questions that have typically remained unexamined.
In this talk I will describe joint research conducted
with Diane J. Litman of AT&T Bell Laboratories that
provides a concrete exploration of these issues. I
will show how plan recognition can be used to support
several classes of interface tasks (advice generation,
task completion, context-sensitive responses, error
detection and recovery), and how such tasks in turn
provide representation and reasoning constraints that
must be satisfied in order for the plan recognizer to
efficiently (if at all) support these tasks. I then
will describe how interfaces are fundamentally limited
by current plan recognition approaches, and use these
limitations to identify and motivate our current
research towards a new generation of plan recognition
systems. Our research is developed in the context of
CHECS (Chemical Engineering Cad System), a plan-based
interface system for computer aided design.
