We are happy to announce that the second batch for BioASQ task 2a
(large-scale biomedical semantic indexing) will take place in a few days!

 

If you are working in any of the following areas: 

 

* Large-scale and hierarchical classification

* Machine learning 

* Semantic Indexing, semantic similarity 

 

then BioASQ Task 2a (large-scale biomedical semantic indexing) is relevant
to your work and you are invited to participate. 

 

Task 2a is be based on the standard process followed by PubMed to index
journal abstracts. The participants are asked to classify new PubMed
documents, written in English, as they become available online, before
PubMed curators annotate (in effect, classify) them manually. The classes
come from the MeSH hierarchy; they are the subject headings that are
currently used to manually index the abstracts. As new manual annotations
become available, they are used to evaluate the classification performance
of participating systems (that classify articles before they are manually
annotated), using standard IR measures (e.g., precision, recall, accuracy),
as well as hierarchical variants of them. The participants are able to train
their classifiers, using the whole history of manually annotated abstracts.

 

Training data, consisting of 10,876,004 documents annotated with MeSH terms,
are already available at: http://bioasq.lip6.fr/ 

 

The challenge is organised in three independent batches of five weeks each,
and has started in February 03, 2014. Therefore potential dates to
participate in Task 2a are:

February 03, 2014,

March 10, 2014,

April 14, 2014.

 

Prizes will be awarded to the winners. Details about the prizes are
available on the Web site of the challenge
(http://www.bioasq.org/participate/prizes).

 

More information about the BioASQ challenge and how different research areas
relate to the challenge tasks is available at:

The BioASQ challenge and workshop are organised by the BioASQ project,
supported by the European Commission within the 7th Framework Programme
(Grant Agreement No. 318652).
