    AI/GI/VI '96
    20 - 24 May 1996
    Holiday Inn on King
    Toronto, Ontario, Canada
    AI/GI/VI '96 is a unique event with three Canadian research conferences
    that present the latest results in artificial intelligence, computer
    graphics and computer vision. Each conference offers three concurrent days
    of invited and submitted papers. For a single registration fee,
    participants can attend presentations in any of the three conferences,
    promoting the exchange of knowledge among these important disciplines.
    Time has been set aside for workshops and other events. A banquet and
    electronic theatre provide additional opportunities to meet speakers and
    other attendees for informal discussion in a social setting. The three
    conferences are sponsored by the Canadian Society for Computational Studies
    of Intelligence, the Canadian Human Computer Communications Society and the
    Canadian Image Processing and Pattern Recognition Society
    The 1996 conferences will be held at the Holiday Inn on King, in Toronto,
    Ontario. Toronto is located on the north shore of Lake Ontario and is
    Canada's largest city. The Toronto International Airport is served by
    major airlines directly from many North American Cities. Direct bus
    service connects the airport with the Holiday Inn. Limousines and rental
    cars are also available.
    Toronto is also the home of the World Champion Blue Jays, at least in the
    years 1992 and 1993. The Holiday Inn On King is a great place to stay. It
    is in the heart of Toronto's business, theatre and entertainment district.
    Minutes from SkyDome, Roy Thomson Hall, the Royal Alexandra and the
    Princess of Wales Theatre, hosts to the world's greatest entertainers. Also
    a short walk from the CN Tower, Convention Centre and the trendy Queen
    Street shopping district. If you'd like to explore Toronto's multicultural
    mosaic, you're just a few blocks from Chinatown and close to restaurants
    offering cuisine that reflects the international flavour of Toronto.

    Information Gathering from Global Networks
    Tuesday, 21 May 1996

    Background: With the rapid growth of the Internet, the information
    explosion is becoming an immediate concern for everyone. Both the number of
    users and the amount of accessible information on the internet have been
    growing exponentially.
    The sheer joy of browsing the world and the frustration of not finding the
    right nugget of information have attracted researchers from many fields to
    the problem of gathering knowledge from a network. What can AI researchers
    bring to the problem? Are we just trying to justify the time we waste
    surfing the net by calling it research? Or will software agents (or some
    other AI techniques) succeed where traditional Information Retrieval
    technology has stalled?

    The Workshop: In the workshop, we hope to address some of the following
    questions in the context of information gathering work being conducted by
    AI researchers. Submitted papers may describe speculative, partial, or
    completed work, provided the work has clear, practical implications for
    other researchers.

    Workshop Format: The workshop will consist of formatted presentations and
    speculation sessions. Of course, we also welcome demonstrations. The
    presenters will be asked to describe the view of networked information and
    the view of the future that led them to their work.

    Submission Information: Submissions are due 2 April 1996. Your paper should
    not be longer than 8 pages (12 point font). All submissions will be
    refereed. We expect the papers to be well organized and to represent a
    contribution to the workshop.
    Please send email to Joel Martin at the National Research Council of
    Canada: "" with the PostScript file of, or a URL pointer
    to, your submission. Do not forget your name and physical mailing address.
    If you wish to show a demonstration or video, please describe your
    hardware/network requirements.

    What is Inductive Learning?
    On the foundations of AI and Cognitive Science
    Monday & Tuesday, 20 & 21 May 1996

    A workshop in conjunction with the 11th Biennial Canadian AI Conference to
    be held at the Holiday Inn on King, Toronto during 21 - 24 May 1996 This
    workshop is a long overdue attempt to look at the inductive learning
    process (ILP) as the central process generating various representations of
    objects (events).
    To this end one needs, first of all, to have a working definition of the
    ILP, which has been lacking. Here is a starting point: ILP is the process
    that constructs class representation on the basis of a (small) finite set
    of examples, i.e. it constructs the INDUCTIVE class representation. This
    class representation must, in essence, provide INDUCTIVE definition (or
    construction) of the class.
    The constructed class representation, in turn, modifies the earlier
    representation of the objects (within the context specified by the ILP).
    Thus, any subsequent processes, e.g. pattern recognition, recall, problem
    solving, are performed on the basis of the newly constructed object (event)
    representations. To put it somewhat strongly, there are only inductive
    We encourage all researchers (including graduate students) seriously
    interested in the foundations of the above areas to participate in the
    workshop. Both theoretical and applied contributions are welcomed
    (including, of course, those related to vision, speech, and language).
    While extended abstracts will be available at the workshop, we are planning
    to publish the expanded and reviewed versions of the presentations as a
    special issue of journal Pattern Recognition.

    Submit a copy (e-mail submissions are encouraged) of a 3-4 page extended
    abstract to:
