WORKSHOP DESCRIPTION
People constantly relate their spatial perceptual (eg. visual) experiences to
one another, conveying the size, shape, orientation and position of objects
using a wide range of spatial expressions. The semantic treatment of such
expressions presents particular challenges for natural language processing.
The meaning representation used must be capable of distinguishing between
fine-grained sense differences and ambiguities grounded in our experiential
and perceptual structure.
On-going research projects that in part address the problem of representing
and processing spatial expressions include:
o Dialogue understanding using "mental images".
o Interfaces to multi-media systems, for example, natural language querying
of photographic databases.
o Machine translation systems, finding a systematic approach for translating
spatial expressions correctly is notoriously difficult.
o Natural language instruction of animated and virtual agents.
o Spatial queries for Geographic Information Systems (GIS).
Implicit in current interest in integrating vision and natural language
processing (AAAI-94 Workshop and AAAI-95 Fall Symposium on Integrating
Natural Language and Vision Processing) is the issue of how to understand
and generate spatial expressions. While a distinctive body of work has
addressed this particular issue, the treatment of spatial language in its own
right has typically not been fully documented. This workshop will provide a
forum for more focussed expositions both on current and past research into
the representation and processing of spatial expressions.
WORKSHOP ISSUES:
There are been many different approaches to the representation and processing
of spatial expressions including geometric schemas, semantic nets, fuzzy sets
and predicate logic. Yet most existing computational characterisations have
so far been restricted to particularly narrow problem domains, that is,
specific spatial contexts determined by overall system goals.
To date, artificial intelligence research in this field has rarely taken
advantage of studies of language and spatial cognition carried out by the
cognitive science community. One of the intentions of this workshop is to
bring together researchers from both disciplines in the belief that
artificial intelligence has much to gain from an appreciation of cognitive
theories.
In addition to presenting original research participants will be asked where
possible to address the following questions:
o How does your work draw upon, differ from, refine or extend existing
linguistic, cognitive and artificial intelligence approaches? What are the
limitations and assumptions of your approach?
o How should knowledge about space be represented? What is your underlying
knowledge representation and reasoning formalism and what issues have
motivated your choice?
o How important is the issue of cognitive plausibility?
o How should the lexicon be organised with respect to spatial prepositions
and spatially relevant words? How can multiple meanings for such words be
accommodated?
o The meaning of spatial expressions cannot be addressed in isolation. Indeed
spatial expressions are used in many different physical contexts and
environments. How should the meanings of individual spatially relevant
words be composed during processing to obtain meanings of complex spatial
expressions?
o Object knowledge is generally thought to play an important role in the
interpretation of spatial words especially spatial prepositions. How can
this be realised and are there any other factors which affect the
interpretation of spatially relevant words?
o How language dependent is your approach?
o What are the open questions?
WORKSHOP FORMAT:
o Formal presentations. These will be short to short discussion. Presenters
will be asked not only to give an account of their own research but also
include responses to questions supplied the reviewing committee.
o Small group sessions. Groups of four or five participants will address
particular problems and/or approaches and make a brief presentations back
to the workshop.
o Panel session.
o Applications session. An applications session will provide participants
with an opportunity to give demonstrations their systems (both complete
systems and systems under development).
ATTENDANCE:
It is intended that between 30 and 40 people will attend the workshop. All
workshop participant are expected to register for the main IJCAI conference.
SUBMISSION REQUIREMENTS:
Electronic submission is strongly encouraged (preferably self-contained
LaTeX). Papers must be printed to 8 1/2" x 11" size. They must be a maximum
of 15 pages, each page having no more than 43 lines, lines being at most
140mm long and with 12 point type. Title, abstract, figures and references
must be included within this length limit. Four copies should be mailed to
the address below. Double sided printing is encouraged.

CALL FOR PAPERS
PPAI-95
Third International Workshop on
Parallel Processing for Artificial Intelligence
2 Days During the Period: August 19-21, 1995
(Before IJCAI-95)
Montreal, Canada
The Third International Workshop on Parallel Processing for Artificial
Intelligence will be held in Montreal, Canada in conjunction with
IJCAI-95. This workshop follows in its format two successful workshops
on the same topic, held at IJCAI-91 and IJCAI-93.
At IJCAI-93, Parallel AI was finally established in the main stream
of Artificial Intelligence. This fact is supported by the number
of papers and activities in the Proceedings that pertain to Parallel
AI, and by the Computers and Thought Award given for work in Massive
Parallelism.
The intent of this workshop is to bring together hardware architects, AI
researchers, and application engineers who are engaged in or interested
in parallel artificial intelligence. Through key presentations and
ample discussions, it is hoped that the workshop will facilitate the
exchange of ideas among researchers and contribute to bridging the
gap between hardware architects and AI researchers. The granularity
of parallelism discussed at the workshop will range from coarse-grain
to fine-grain parallel processing.
The program committee invites submission of high quality contributions
on parallelism in AI. Topics of interest include but are not limited
to the following:
-- Parallel Algorithms for AI
Parallel Search, Problem Solving, Planning, Constraint-Satisfaction,
Decision Making, Natural Language Processing, Vision, etc.
-- Parallel Inference Systems
Parallel Knowledge Representation and Reasoning,
Parallel Deduction, Automated Theorem Proving, Concurrent Logic
Languages, Implementations, Performance Evaluations, etc.
-- Massive Parallelism for AI
Massively Parallel Machines (Architecture, Benchmarks, etc.),
Spreading Activation, Connectionism, Bulk Data Processing,
Memory-Based Reasoning, etc.
-- HW and SW for Parallel AI
Parallel Architectures, Parallel Implementations of AI Languages,
System Level support for AI, High Speed Disk I/O, etc.
-- Progress reports from major parallel AI projects (RWC, HPCC, etc.).
Please submit two (2) copies of a detailed abstract (approx. 1500 words)
or a full paper (limited to 5000 words) to each of the three workshop
chairmen listed below (i.e., a total of six copies) by March 1, 1993.
Please send, if possible, an e-mail version of your paper to the chairmen
as well (Plain Latex, or ASCII, or Compressed Postscript). All submitted
papers will be reviewed by the workshop committee. Informal proceedings
containing accepted contributions will be made available for the workshop.
Similarly, as for the previous PPAI workshops, we intend to publish a
book afterwards based on selected papers from the workshop. The previous
books were published by North-Holland in the Machine Intelligence and
Pattern Recognition Series (volumes 14 and 15).
SCHEDULE
Papers due: March 1, 1995
Notification of Acceptance: April 1, 1995
Camera-ready edition due: April 20, 1995
REGISTRATION
WORKSHOP PARTICIPATION IS NOT POSSIBLE WITHOUT REGISTRATION FOR THE
MAIN IJCAI-95 CONFERENCE. In addition, each attendee needs to pay a
small registration fee for the workshop. See the IJCAI brochure for
the exact amount.
WORKSHOP FORMAT
The workshop will run for two days. It will consist of several
invited talks for hot topics, panels/discussions, and technical
sessions with submitted papers. Basically, this inherits the
format used in the IJCAI-93 workshop, which was proven to be
effective. Two potential topics for invited talks are the HPCC
and RWC initiatives. In addition, we are planning to organize
special topic sessions on specific problems which are of interest
to a majority of the workshop attendees. All presentations will
be limited in length, so that ample time for discussion is left
after each individual paper. Additional time for discussion
will be allocated at the end of each session.
