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.
