1. Intentions

The scholarly and scientific tradition in lexical research
was given an engineering edge by three outbursts of massive
lexical work that began in the last decade, the CYC project
in the United States, the EDR project in Japan, and the
Grosseto Workshop whose principle of reusability generated a
series of EC projects including Acquilex, ET-7, Multilex,
and Genelex. These projects led to, and were equalled by,
world wide interest in statistics on very large corpora. The
close inter-relationships between Lexicon development and
Corpus analysis are increasingly accentuated. This
international drive on the lexicon over a period of a decade
has done the field an immense service.

However, recent reflections on the lexical research over the
last ten years are not always as favourable as one might
expect. Wilks (1993) made a criticism of IBM's approach to
Machine Translation. The main point was that there is a
natural ceiling of success to PURE statistical methods. Ide
and Veronis (1993) went so far as to ask if we have wasted
our time over the last decade on extracting knowledge from
machine-readable dictionaries.

Another area of concern nowadays is the development of
common lexical specifications, or lexical standards. Up to
which level of lexical description can standards be
proposed, to ensure data reusability?

Furthermore, one important development in AI and Cognitive
Science in recent years warrants the attention of lexical
researchers. It involves the trend for the integration of
NLP with various subareas of AI, e.g. computer vision (see
Dennett, 1991; Mc Kevitt, 1994). The need for unified
representation scheme incorporating both perceptual
information and common sense knowledge poses new challenges.

The proposed workshop attempts to clarify issues in current
lexical research in terms of further research directions as
an answer to recent challenges. Suggested topics are as

a) notes comparing between well-known lexical projects,
particulary the EDR project, the CYC project, and the EC
projects --what have we learned ?

b) lexical needs for unified representations of common sense
knowledge and perceptual knowledge, visual or audio
--brainstorming on the design and construction of the
lexicons for such integrated systems;

c) lexical needs of very large knowledge bases for nuclear
lexicons as the core for knowledge acquisition --
speculations and practice concerning the design and
construction of such nuclei.

2. Format

This workshop is intended as an opportunity provided for the
exchange of views on issues of common concern to the area of
lexical research. Panel sessions and discussions are
stressed rather than formal speeches. All activities at the
workshop are intended as reactions to recent challenges.

The workshop will take place on the beautiful Tsinghua
University campus on the outskirt of Beijing.

Day 1: the state-of-the-art discussion -- achievements,
issues and concerns
Day 2: lexical needs for integrated systems
Day 3: lexical needs for knowledge acquisition for very
large knowledge systems

Each attendee of the workshop pays $100 to cover
registration, preprints,local transportation from and to
Beijing Airport, and hotel + food expenses for the 3-day
workshop duration. Air fare to and from Beijing rests with
all attendees themselves.

Registation forms will be sent out to workshop attendees upon
request. All correspondence concerning workshop registration
should be directed to Chengming Guo by fax, e-mail, or postal
mail at the Computer Science Department, Tsinghua University,
Beijing, 100084, China. To ensure proper accomodation, special
pre-arrangements have to be made with Chengming Guo, should
the attendee wish to arrive earlier than August 14th and/or
stay a little longer after the workshop ends on the 17th of

3. Submission requirements

Papers of no more than 6 pages should be submitted by
e-mail to the co-chairs of the workshop at
"" for Nicoletta Calzolari,
and at "chengming%bepc2scs.bitnet" for Chengming Guo.
Postal mail of three hard copies of the paper to Nicoletta
Calzolari and Chengming Guo are also acceptable. Papers must
be printed to 8 1/2 to 11" size. Workshop preprints will be
made available to all attendees.

Paper submission by the 15th of May, 1994
Notification of acceptance by 5th June, 1994
Camera-ready copy by 30th of June, 1994
