Message 1: ECAI-96 Workshop on Spatial Expressions

Date: Sun, 19 May 1996 18:08:20 BST
Subject: ECAI-96 Workshop on Spatial Expressions


 ECAI-96 Workshop
 Representation and Processing of Spatial Expressions

 European Conference on Artificial Intelligence (ECAI-96)
 Budapest University of Economics
 Budapest, Hungary

 Tuesday 13th August 1996

Following the success of the first workshop held at IJCAI-95 in
Montreal, the 2nd Workshop on the Representation and Processing of
Spatial Expressions is to be held at ECAI-96 in Budapest, Hungary on
Tuesday 13th August 1996.

Though here are been many different approaches to the representation
and processing of spatial expressions, most existing computational
treatments have been restricted to particularly narrow problem
domains, usually specific spatial contexts determined by overall
system goals. To date, AI 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.

The workshop will consist of formal presentations, prepared
commentaries on presenations and two ``taking issue'' discussions
sessions (on ''Function'' and ``Shape'') led our invited speakers.

Message 2: SIGLEX96 CALL FOR PARTICIPATION for "Breadth and Depth of Semantic Lexicons"

Date: Wed, 22 May 1996 11:16:51 MDT

Subject: SIGLEX96 CALL FOR PARTICIPATION for "Breadth and Depth of Semantic Lexicons"



June 28, 1996
Santa Cruz, California, USA.	

- -------------------

Building semantic lexicons is a very time consuming task. Efficient
large-scale acquisition and representation of lexical knowledge will
be greatly aided by capturing regularities in the lexicon.

Two main issues present themselves:

a) treatment of lexical ambiguity and
b) lexical rules as a conceptual tool for controlled proliferation of

Whereas the former has been regarded as a topical issue for quite some
time, the latter is only now receiving its due attention. This
workshop will concentrate on lexical rules as a regulator of breadth
and depth of the lexicons. Lexical rules are known under a variety of
names, e.g., Leech's (1991) "semantic transfer rules," "lexical
inference rules" of Ostler and Atkins (1991) and others. They are also
addressed in the framework of such theories as the generative lexicon
of Pustejovsky (1995). Such linguistic frameworks as LFG and HPSG have
also used the concept, albeit in a different sense and for a different
purpose. At the same time, theoretical accounts of the use of lexical
rules (such as, for instance, preemption or blocking) are rather too
general and underspecified to support actual processing. The workshop
will stress issues connected with the practical application of lexical
rules: when to apply the rules, how the rules influence system design,
how to reexamine and adjust the theoretically posited rules in view of
practical needs and evidence. Another central issue for the workshop
will be large-scale acquisition of computational-semantic lexicons.
We are mainly interested in examining the following trade-offs: the
coverage vs.the depth of existing semantic lexicons vs. the effort
involved in building them.

The workshop is intended for researchers in computational linguistics,
artificial intelligence, psycholinguistics or other fields who have
been working in lexical semantics and large-scale lexical knowledge

Some (though not necessarily all) specific questions suggested for
discussion include:

1) What are the different types of lexical rules which should be
considered in the building of computational lexicons (inflectional and
derivational morphology, verbal diatheses, regular word-sense shifts,

2) When should the rules be applied (run-time, load-time,
acquisition, other)

3) How to evaluate the cost-efficiency of the acquisition effort
against the utility of the resulting lexicons. How could we
characterize an NLP system along the dimensions of size, corpus
coverage, and depth.

4) Analyses of appropriate types of inheritance for different lexical

5) The use of lexical underspecification (and contextual word-use
grounding) as a partial alternative to lexical rules.

The meeting is scheduled from 8:30am to 6pm. The papers will be
organised around topics followed by discussions. A summary general
discussion will be scheduled at the end of the day. Attendees are
required to register for the main ACL-96 conference.
