Message 1: AMTA-96 Machine Translation Conference

Subject: AMTA-96 Machine Translation Conference

 --- CONFERENCE ANNOUNCEMENT AND CALL FOR SUBMISSIONS ---
 Association for Machine Translation in the Americas

 AMTA-96 Conference, Montreal, October 2-5, 1996

 Accelerating Machine Translation Development:
 Research, Business, and Personal Use

Following the very successful AMTA conference near Washington, DC in
October 1994, the second conference of the Association for Machine
Translation in the Americas will be held in Montreal, Canada, at the
Radisson Hotel, on October 2-5, 1996.

Once again there will be something for everyone! Retaining the pattern
established by its predecessor, AMTA-96 will offer a blend of invited
talks, panel discussions, research papers, system demonstrations and
descriptions, tutorials, workshops, book exhibits, and social events.
The three days of the conference will also facilitate gatherings of
the Special Interest Groups on topics ranging from interlinguas and
ontologies, lexicons, standards and data exchange, MT on PCs, and MT
evaluation.

The overall intent of the conference is to bring together MT developers,
researchers, and users, to share the latest information on MT and to
forge partnerships for addressing the challenge of language barriers
that impede communication on the Information Highway. Participation
by members of AMTA's sister organizations in Europe and Asia is
strongly encouraged.

Invited talks and panel discussions will highlight topical and contro-
versial questions, encouraging lively interactions, as they did at
AMTA-94. In the theory sessions, technical papers will address a
wide range of topics, while in practical sessions, the problems of
developing and bringing MT systems to market will be discussed, with
online demonstrations. In addition, booths can be rented to display
systems and products.

AMTA will also hold its General Members' Meeting during the conference.

Message 2: ACL'96 Workshop on BREADTH & DEPTH of SEMANTIC LEXICONS

Subject: ACL'96 Workshop on BREADTH & DEPTH of SEMANTIC LEXICONS

		 LAST CALL for PAPERS

ACL'96 Workshop on the 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
entries.

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
acquisition.

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,
other)

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
rules.

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

Computational and descriptive case studies are welcome. However,
submissions should centrally address one of the above issues rather
than simply describe a system or a theory. We greatly encourage the
submission of original and unplished work.

WORKSHOP ORGANIZATION:
Presentations will last for 30 minutes, of which at least 5 minutes
(preferably, more) must be allocated for discussion. Papers will be
organized around themes. A summary general discussion will be
scheduled at the end of the day.
Attendees are required to register for the main ACL-96 conference.
