Date received: 02 May 2013
Deadline: 15 May 2013
Start date: 23 Sep 2013





CALL FOR PAPERS / PARTICIPATION -- CLEF-ER 2013 Workshop (CLEF
Conference) Valencia, 23-26 Sep 2013 CLEF-ER 2013: Named Entity
Recognition (NER) in parallel multilingual biomedical corpora
(aiming for terminology translation) apologies for crossposting

CALL FOR PAPERS
-- -- -- -- -- -- -- -- -- -- -- --
We are interested in papers describing challenge systems or
related research and position papers, tackling questions like:
- Can we build multilingual biomedical terminologies from
  parallel biomedical corpora?
- How do we exploit machine translation methods to identify
  correspondences in parallel corpora?
- Do we encounter the same semantic representation in different
  languages?
- Can we make use of crowd-sourcing solutions to produce
  comprehensive terminological resources? Please submit us an
  extended abstract (normally 2 pages) via EasyChair:
  https://www.easychair.org/conferences/?conf=clefer2013 Accepted
  abstracts will become part of the CLEF proceedings. The best
  contribution wins a prize, which is the waiving of publication
  costs in an open access journal!

CALL FOR CHALLENGE PARTICIPATION
-- -- -- -- -- -- -- -- -- -- -- --
Objectives: Multilingual identification of mentions of named
entities (attribution of CUIs) in corpora, where each corpus is
either in English, French, German, Spanish, and Dutch. Currently
patent texts, titles of Medline abstracts and EMEA documents
serve as parallel corpora. The mention annotations will be
evaluated as part of the challenge and, in addition, the mention
annotations will be analysed to contribute to an augmented
biomedical terminological resource.

Task: Participants produce mention annotations in a multilingual
document where the annotations make explicit reference to
entities, which are specified through a Concept Unique Identifier
(CUI, from the UMLS). Challenge participants should at least
contribute one non-English annotated corpus and have to register
at the submission site (http://www.clefer.org/access-content).

A number of resources are available too:
(1) a terminological resource (TR) containing English and
    non-English concepts in combination with their CUIs,
(2) a selection of corpora in English, where the entity mentions
    have been annotated automatically with their CUIs, and
(3) a selection of corpora in different languages other than
    English (i.e., de, fr, sp, nl) that have to be annotated with
    entity mentions and their CUIs.

Note: Each non-English corpus has a parallel English corpus. Not
all languages (de, fr, sp, nl) are available for each corpus.
Parallel corpora offer the opportunity to use machine-translation
or bilingual term identification methods. The results will be
presented on the CLEF-ER workshop, which is part of the CLEF 2013
Conference, 23-26 September in Valencia, Spain. The challenge is
sponsored by the EU project "Mantra". For more details on the
task please visit http://www.clefer.org/ or send an email to
challenge_(at)_clefer.org
