[ntcir:140] CFP: IWSLT2004: International Workshop on Spoken Language Translation

INTERSPEECH/ICSLP-2004 satellite workshop
International Workshop on Spoken Language Translation
- Evaluation Campaign on Spoken Language Translation -

*** Final Call for Participants / Papers ***

September 30 - October 1, 2004
ATR Spoken Language Translation Research Laboratories
Kyoto, Japan


Spoken language translation technologies attempt to cross the language
barriers between people having different native languages who each want
to engage in conversation by using their mother-tongue. The importance
of these technologies is increasing because there are many more
opportunities for cross-language communication in face-to-face and
telephone conversation, especially in the domain of tourism.

Novel technologies have been proposed to tackle the problems in spoken
language translation research. A number of institutes are developing huge
bilingual or multilingual spoken language corpora. MT technologies based on
machine learning, such as statistical MT and example-based MT, are being
applied to the translation of spoken language by using these corpora. Some
of the characteristics of spoken language seem suitable for the application
of machine-learning-based MT in comparison with written language.
However, there is still no concrete standard methodology for comparing the
translation qualities of spoken language translation systems.

One of the prominent research activities in spoken language translation is
the work being conducted by the Consortium for Speech Translation
Advanced Research (C-STAR III), which is an international partnership of
research laboratories engaged in automatic translation of spoken language.
Current members include ATR (Japan), CAS (China), CLIPS (France), CMU
(USA), ETRI (Korea), ITC-irst (Italy), and UKA (Germany). One of C-STAR's
ongoing projects is the joint development of a speech corpus that handles
a common task in multiple languages. The creation of such a corpus will not
only enable translation among multiple languages but will also facilitate
exchange and discussion of research results among member labs. As a first
result of this activity, a Japanese-English speech corpus comprising
related sentences, originally compiled by ATR, has been translated into the
native language of C-STAR members.

In this workshop, an "evaluation campaign" of spoken language translation
technologies will be held by using the multilingual speech corpus
the tourism-related sentences developed by ATR and C-STAR members.
Two types of submissions are invited: 1) participants in the evaluation
of spoken language translation technologies, and 2) technical papers on
issues. An overview of the evaluation campaign is as follows:

Main Theme: Evaluation of spoken language translation systems

Corpus used for the evaluation campaign:
- Basic Travel Expression Corpus (BTEC)
- Languages: Chinese-English, Japanese-English
- Domain: tourism-related sentences
- Media: text in utterance style
- Number of Sentence Pairs: 20,000 for each translation direction

Tracks of the Evaluation Campaign:
- Translation directions:
Chinese to English
Japanese to English
- Resources Used:
Supplied corpus only (C-to-E, J-to-E)
Supplied corpus + additional linguistic resources available from LDC
Unrestricted (C-to-E, J-to-E)

Evaluation Methodology of Translated Results
- Subjective Evaluation
- Automatic Evaluation (BLEU, NIST, WER, etc)

The workshop also invites technical papers related to spoken language
Possible topics for the session include, but are not limited to:

- MT Evaluation Measures
- MT Algorithms
- Word / Phrase Alignment
- Multilingual Lexicon / Translation Rule Extraction
- Multilingual Parsing
