 Bird-of-a-feather Workshop
 at the 
 Genetic and Evolutionary Computation Conference 2001
 ( GECCO-2001 )

 San Francisco, California, July 7 - 11, 2001 (Saturday - Wednesday)


Paper submission deadline: 	March 12, 2001
Decisions will be mailed by: 	April 5, 2001
Submissions of camera-ready papers: 	April 20, 2001
Presentation: 	July 7, 2001


Finding good solutions for network design problems is important in
many fields such as telecommunications, computer, backbone access,
transportation and distribution networks. Over the last years genetic
algorithms have been applied with success to a wide variety of these
different problems. One of the major design issues is how the network
could be represented as an artificial chromosome and what kind of
operators could be defined on the chromosome.

The workshop is intended to give an overview over the existing
approaches and to discuss various representations and operators in the
context of genetic and evolutionary computation. It should compare
theoretical properties and empirical performance characteristics of
different representations and operators and try to find explanations
for performance differences of a genetic algorithm. The workshop will
be focused on representations and operators for network problems, but
it welcomes interesting contributions to encoding issues that are
meaningful for network representations.


Presentations will be selected according to the submitted 10-page 
papers which will be reviewed by at least two members of the 
international program committee. Accepted papers will be available 
in electronic form before the workshop. Abbreviated versions of 
the papers will be later published in the workshop proceedings. 
The length of each paper will be determined by the number of 
accepted papers.

 research as well as the ones who would like to learn more 
 about representations and networks.

Message 2: Modular Programming applied to NLP (EUROLAN'01)

Date: Fri, 02 Mar 2001 16:19:45 +0000
From: Constantin Orasan <>
Subject: Modular Programming applied to NLP (EUROLAN'01)


Workshop on 'Modular Programming applied to Natural Language Processing'
 Held as part of EUROLAN'01 Summer School
 July 30 - August 11
 Iasi, Romania


The effectiveness of modular programming in designing software has long
been acknowledged by the computer science community. However, the
computational linguistics community preferred to develop components in
isolation, without integrating existing modules into proposed systems.
There are several reasons for this. Firstly, integration of different
modules is not a trivial task, requiring a lot of time. Usually the
major problem is the loss of information caused when the output of one
module has to be converted to the input of another. Most research
projects do not have the time or resources to concentrate on a real
modular architecture, using trade offs (such as manually created inputs)
instead. Secondly, most of the work in the research community is
directed towards proposing and demonstrating new hypotheses, and not
building robust and fully automatic applications. In many cases
preprocessing steps, which produce the input data for the tested method,
are considered trivial and accurate, and as a result replaced with hand
produced data. Therefore, when a researcher needs a certain module for a
method, s/he prefers to produce the output of that program manually,
either because s/he is not aware of an existing implementation which
performs the required task, or because the work involved in setting it
up is greater than that involved in manually producing the output
(usually because the implementation was developed and tested on a
different platform).

However, this situation has started to change rapidly. More and more
researchers have appreciated the complexity of NLP tasks and the need to
use modular programming. A quick look at the systems presented at the
latest MUC indicated that they are complex systems which reuse previous
research. Systems like GATE have been designed in order to help with the
integration of different modules in a system. In addition, the research
community is increasingly requiring the development of fully automatic

This workshop will provide a forum for discussion between researchers
involved in the development of automatic NLP systems and leading names
in the field. We would like to invite all researchers to submit their
original and unpublished work to the workshop. Topics of interest
include but are not limited to:
- modular architectures for NLP
- black/glass box evaluation measures
- research on the influence of substitution and alternate combinations
of modules on overall system performance
- reusability
- integration of resources (including conversion formats between
- platforms for developing modular applications
- repositories
Demos of the presented systems are encouraged. 

Submission Requirements

Papers should describe original work in progress or completed work. The
main purpose of presenting at the Workshop is to exchange ideas with
other researchers and to receive helpful feedback for further
development of the work. 

The submissions should not exceed 10 pages with 12pt Times New Roman
font including figures, references, and appendices. Authors will be sent
details of the final format for camera-ready versions together with
notification of acceptance. Each paper will be reviewed by at least two
members of the program committee.

Electronic submissions are encouraged but hard copies are acceptable.
For electronic submission, papers should be in Postscript, PDF,
Microsoft Word, or RTF format. For other formats, please contact the
organising committee. All papers should be sent to
