BioCreative II.5 Challenge (2009)

[http://www.biocreative.org]

Can Information Extraction contribute to the creation of Structured  
Digital Abstracts (SDAs)?

*) BioCreative II.5 builds on the FEBS Letters experiment for the  
creation of SDAs.
*) BC II.5 will systematically assess the potential use of automated  
IE in the curation of full-text articles.

CALL FOR PARTICIPATION

OVERVIEW

The BioCreative challenge evaluation consists of a community-wide  
effort for promoting the development and evaluation of text mining and  
information extraction systems applied to the biological domain.  
Previous BioCreative challenges attracted considerable interest not  
only in the bio-text mining community but also in the bioinformatics  
and biological database domain, resulting in two special journal  
issues and useful data resources for the development of biomedical  
text mining systems.

BioCreative II.5 will evaluate real-time text mining capabilities on  
full text articles and explore future possibilities for author-
assisted annotations using information extraction tools.

Interesting new aspects of BioCreative II.5 relate to:

1) The use of an online MetaServer platform as basic evaluation  
infrastructure, allowing direct comparison of multiple participating  
systems.
2) Collaboration of article authors, publishers and expert human  
annotators (for the preparation of task resources).
3) Use of full text articles in various formats including XML.
4) Alignment of various tasks on a common data collection.

TASKS

1) INT - Interaction normalization task
(Given an article extract a set of biological entities, namely  
mentioned interactor proteins)
2) IPT - Interaction pair task
(Extraction of biological relations, namely pairs of interacting  
proteins)
3) ACT - Article categorization task
(Binary classification of articles as relevant for extracting  
interaction annotations)

For more information on the tasks, please visit the website at:

EVALUATION

Evaluation will be based on direct comparison of automatically  
generated predictions by participating systems against a Gold Standard  
of manually generated annotations, so-called Structured Digital  
Abstracts (SDAs) generated by the original article authors themselves  
as well we by expert biological database annotators. In order to  
assure a more robust evaluation setting and to be able to directly  
compare and visualize different online predictions the BioCreative  
MetaServer (BCMS) platform will be used.

PUBLICATIONS

The BioCreative II.5 challenge will result in high-impact publications  
following the line of previous BioCreative publications, including  
collaborative papers, evaluation articles and technical descriptions.
