    Interpreting information requests in context

    BISC Seminar

    Charles L. Ortiz, Jr.
    Artificial Intelligence Center
    SRI International
    March 8, 2001
    380 Soda Hall
    4:00pm-5:00pm
    **5:00pm-5:45 pm; Discussion to follow seminar**

    Abstract:

    In this talk I will describe the use of theories of agent collaboration and
    human dialogue processing in providing a principled basis for the design of web
    interfaces to multimedia information stores. I will discuss a system called DIAL
    to illustrate the efficacy of this approach. DIAL builds a representation of
    context that is based on the collaborative plans of the system and its user and
    uses this contextual information to reduce the communication burden. Context is
    represented by a structure of intentions that a user is pursuing. This structure
    is modified as tasks are completed or task descriptions are refined. DIAL
    interprets information requests relative to the prevailing context as it is
    represented by this structure. As a result, requests can be expressed more
    economically; contextual information is added by the system. Furthermore, DIAL
    uses information about the intentional context to respond and act
    collaboratively, rather than in the master-slave style typical of most current
    human-computer interfaces. DIAL and the access method it supports provide a
    unique support tool for distance learning environments as well as a
    demonstration of a general way in which agent models can be used to improve
    human-computer communication.

    This is joint work with Barbara Grosz of Harvard University.

    BIO:
    Charles Ortiz is a Senior Computer Scientist in the Artificial Intelligence
    Center at SRI International. His research interests include reasoning about
    action and causation, collaborative multi-agent systems, and distributed
    robotics. He holds an S.B. in physics from MIT and a Ph.D. in computer science
    from the University of Pennsylvania for his work on causation. From 1996-1998 he
    worked on collaborative multi-agent systems as a postdoctoral fellow at Harvard
    University. He is currently the principal investigator for a DARPA research
    project on incremental negotiation for autonomous agents and also for an ONR
    project on distributed continual planning and execution for autonomous air
    vehicles. He is the past director of the SRI Applied AI Technology Program.
