[Corpora-List] ACL-2003 Workshop CFP: 2nd International Workshop on Paraphrasing

[Priscilla Rasmussen]

 ============================================================================

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

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.
