Subject: ACL Software Demonstrations Program (ACL'2000)


	Call for Proposals: ACL Software Demonstrations Program
The ACL 2000 Program Committee invites proposals for the
Demonstrations Program, to be held in Hong Kong from October 3rd
through 6th 2000 in Hong Kong. The focus of the demonstrated systems
should be on research prototypes, both under development and finished,
that demonstrate the progress in all fields of computational
linguistics and language technology. This program is not for
commercial systems which should be part of the ACL 2000 Exhibit

Areas of Interest

We would like to encourage the submission of proposals for
demonstrations of software related to any areas of computational
linguistics and language technology.

Areas of interest include, but are not limited to:

* Demonstrations related to the thematic sessions

 o T1: NLP and open-domain question answering from text 
 o T2: Machine learning and statistical NLP for dialog
 o T3: Text summarization 
 o T4: Theoretical and technical approaches for Asian language processing

* Natural language processing systems, e.g., dialog systems or machine
 translation systems, and tools to build them

* Application systems using language technology components

* Software for the evaluation of systems and research

* Language corpora and related tools

* Aids for teaching computational linguistics

Format for Submissions

Demo proposals must include the following parts, which should all be
sent to the Demonstrations Chair

* An abstract of the technical content to be demonstrated, not to
 exceed two pages, including title, authors, full contact
 information, thematic session or area, keywords, references and

* A short presentation script, including the basic items of the
 accompanying narrative, and either a web address for accessing the
 demo or visual aids (e.g., screen-shots, snapshots, or sketches). No
 more than 6 pages, total.

* A detailed description of hardware and software requirements
 expected to be provided by the local organizer. Demonstrators are
 encouraged to be flexible in their requirements. Please state
 what you can bring yourself and what you absolutely must have
 provided. We will do our best to provide equipment and resources but
 nothing can be guaranteed at this point beyond space and power.
 Please contact the demo chair for any specific questions.

Submissions Procedure

Proposals should be submitted as soon as possible, but before June,
15th, to the ACL 2000 Demonstrations Chair (
Electronic submissions in plain text, postscript, or PDF are

Please submit your proposals and any inquiries to:

Submissions will be evaluated on the basis of their relevance to the
themes of the conference, innovation, scientific contribution,
presentation, and user friendliness, as well as potential logistical

Other Details

The demonstration sessions will be located at the conference venue.
Further details on the timing and format for the sessions will be
determined and provided at a later date. We anticipate charging a 
US$ 40 fee for presenting demos, to help defray costs.

Important Dates

Submission Deadline for Demo Proposal: 15 June 2000

Message 2: ACL Workshop: Comparing Corpora (ACL'2000)

Date: Thu, 15 Jun 2000 17:12:25 EDT

Subject: ACL Workshop: Comparing Corpora (ACL'2000)


			 ACL Workshop:


			 October 2000

	 Hong Kong University of Science and Technology


Anyone who has worked with corpora will be all too aware of
differences between them. Depending on the differences, it may, or
may not, be reasonable to expect results based on one corpus to also
be valid for another. It may, or may not, be appropriate for a
grammar, or parser, based on one to perform well on another. It may,
or may not, be straightforward to port an application from a domain of
the first text type to a domain of the second. Currently,
characterisations of corpora are mostly textual and at different
levels of generality. A corpus is described as ``Wall Street
Journal'' or ``transcripts of business meetings'' or ``foreign
learners' essays (intermediate grade)''. It would be desirable to be
able to place a new corpus in relation to existing ones, and to be
able to quantify similarities and differences.

Allied to corpus-similarity is corpus-homogeneity. An understanding of
homogeneity is a prerequisite to a measure of the similarity -- it makes
little sense to compare a corpus sampled across many genres, like the
Brown, with a corpus of weather forecasts, without first accounting
for the one being broad, the other narrow.

Given the centrality of corpora to contemporary language engineering,
it is remarkable how little research there has been to date on the
question. Biber's work, coming from sociolinguistics, has made a
considerable impact, with various researchers in computational
lingustics taking forward the model (Biber 1989, 1995). Studies in
text classification, genre and sublanguage are also salient, but it is
rarely evident how well the technologies ddeveloped in these fields are
suited to measuring corpus similarity or homogeneity.

The workshop will welcome contributions concerned with measuring and
comparing corpora using quantitative methods, from any field.

Where and when

The workshop will last half a day and will be on either 7th or 8th
Oct, the main ACL conference being 3rd-6th October. The venue will be
the same.

not exceed 3200 words (exclusive of title page and references).
They must be received by July 8, 2000, in hard copy (4 copies)
OR postscript OR rtf format. Electronic delivery is to
