[Corpora-List] Tree-Structured Named Entities corpora ?

[Galibert Olivier]

  Hi,

The Quaero named entities annotation guide follows that kind of structure.  Two corpora are already available through ELRA/ELDA:
- ELRA-S0349 Quaero Broadcast News Extended Named Entity corpus
- ELRA-W0073 Quaero Old Press Extended Named Entity corpus

A third one, linked to the ETAPE evaluation, should be made available sometimes next year.

The annotation guide is available at http://www.quaero.org/media/files/bibliographie/quaero-guide-annotation-2011.pdf

Best,

  OG.

Greetings Corpora-List,

I am currently looking for corpora with tree-structured named entities.

A simple example of tree structuration would be a person which has a first
and last name : "Barack Obama" is a person whose first name is "Barack" and
last name is "Obama". A parsing would then be : *(PER (NAME.FIRST* Barack*)
(NAME.LAST* Obama*))*
Another example would be geographical addresses.

I know some corpora that could fit this definition : the SemEval'2007 task
9 corpora (tree-structured NE in Spanish and Catalan) and the GENIA corpus
(tree-structured NE for biomedical entities in English).

Does any of you know other tree-structured NE corpora ?

Thank you kindly in advance,
