CALL FOR PAPERS
Second International Workshop on Paraphrasing:
Paraphrase Acquisition and Applications
July 11, 2003, in Sapporo, Japan
in conjunction with ACL-2003 (WS5)
http://nlp.nagaokaut.ac.jp/IWP2003/
BACKGROUND
A common characteristic of human languages is the possibility to
convey the same information in several ways. Paraphrases, which in the
literature have also been referred to as variants, reformulations, or
inference rules, span a wide range of variation:
- article / paper / publication
- Oswald killed Kennedy. / Kennedy was assassinated by Oswald.
- a plant in Alabama / the Alabama plant
- Edison invented the light bulb. / Edison's invention of the light bulb
- He plays better than everybody else in the team. / He's the best in the team.
- The tree healed its wounds by growing new bark. / The tree healed
its wounds. It grew new bark.
- The stapler costs $10. / The price of the stapler is $10.
- Where is Thimphu located? / Thimphu is the capital of what country?
This diversity of expression presents a major challenge for many NLP
applications. Thus, automatic paraphrase identification and generation
can benefit a broad range of NLP tasks, including machine translation,
summarization, information retrieval, question answering, generation,
and authoring and reading assistance.
Previous workshops on paraphrasing:
- Workshop on Automatic Paraphrasing, November 2001
accompanying the NLPRS2001 conference, with 55 participants
http://nlp.nagaokaut.ac.jp/pub/NLPRS2001WS.html
- Workshop on Automatic Paraphrasing (in Japanese), March 2001
accompanying Japanese NLP conference, with 165 participants
http://nlp.nagaokaut.ac.jp/pub/NLP2001WS.html
TOPICS OF INTEREST
The workshop will be open to any research topic related to
paraphrases. More specifically, topics of interest include, but are
not limited to:
* definition and typology of paraphrases
* representation of paraphrases
* algorithms for recognizing, generating and choosing among paraphrases
* construction of paraphrase resources
* existing and potential applications of paraphrases:
- question answering, summarization, information retrieval,
machine translation, authoring and reading assistance
- inferencing with paraphrases
* evaluation of paraphrase algorithms and resources
Special topic: Paraphrase Acquisition
The increased availability of parallel corpora and comparable corpora
has opened up possibilities for automatic paraphrase acquisition. As
we have recently witnessed, a number of new methods for paraphrase
extraction have emerged.
The availability of appropriate evaluation techniques is a key part of
a progress in the area. Is it possible to create a common benchmark
for evaluating different paraphrase extraction approaches? On which
terms should different acquisition approaches be compared? How can we
define the notion of baseline?
Another important objective of the workshop is to take a first step
towards a standardized paraphrase resource that could be shared among
a large variety of researchers.
"SOMETHING_1 costs MONETARY_QUANTITY_2"
:is-equivalent-to "the price of SOMETHING_1 is MONETARY_QUANTITY_2"
:can-be-inferred-from "to sell SOMETHING_1 for MONETARY_QUANTITY_2"
Such a resource, with possibly tens of thousands of entries such as
the one above (in one format or another), can be viewed as a valuable
extension of WordNet and holds great promise to advance many areas of
natural language processing.

CALL FOR PAPERS
CoNLL-2003: Seventh Conference on Natural Language Learning
Organized at HLT-NAACL-02, Edmonton, Canada
May 31 - June 1 2003
http://cnts.uia.ac.be/conll2003/
CoNLL is an international forum for discussion and presentation of
research on natural language learning. We invite submission of papers
about natural language learning topics, including, but not limited to:
- Computational models of human language acquisition
- Computational models of the origins and evolution of language
- Machine learning methods applied to natural language processing
tasks (speech processing, phonology, morphology, syntax,
semantics, discourse processing, language engineering
applications)
- Symbolic learning methods (Rule Induction and Decision Tree
Learning, Lazy Learning, Inductive Logic Programming, Analytical
Learning, Transformation-based Error-driven Learning)
- Biologically-inspired methods (Neural Networks, Evolutionary
Computing)
- Statistical methods (Bayesian Learning, HMM, maximum entropy,
SNoW, Support Vector Machines)
- Reinforcement Learning
- Active learning, ensemble methods, meta-learning
- Computational Learning Theory analysis of language learning
- Empirical and theoretical comparisons of language learning methods
- Models of induction and analogy in Linguistics
CoNLL is the yearly meeting organized by SIGNLL, the Association for
Computational Linguistics Special Interest Group on Natural Language
Learning. After previous CoNLL meetings were held in Madrid (1997),
Sydney (1998), Bergen (1999) Lisbon (2000), Toulouse (2001), and
Taipei (2002).

for more information about SIGNLL and CoNLL.
Special Theme
- -----------
As in previous years, in addition to submissions on the general topics
listed above, we encourage submissions on a special theme. This year's
special theme is:
Semi-supervised / unsupervised learning and sample selection
techniques for language learning (co-training, active learning,
EM, etc).
Supervised Machine Learning methods suffer from a "data annotation
bottleneck" which is especially harmful for language learning tasks
where a lot of training data is needed (e.g. parsing). Sample
selection techniques, and combination of supervised learning with
semi-supervised and unsupervised techniques may provide a solution to
this problem.
Shared Task
- ---------
This year's workshop will also accept submissions for a shared task:
machine learning approaches to named entity recognition. Special
attention will be given to the use of multiple sources of knowledge,
like training data, lists of examples and unannotated data.
Interested groups will be supplied with the same training and testing
material (in several languages), and will all use the same evaluation
criteria, thus allowing comparison between various learning methods.
More information on the shared task will be available at:
http://cnts.uia.ac.be/conll2003/ner/
