[CALBC annotations are available from a triple store, although a
SPARQL endpoint hasn't been made public yet. After his presentation to
BioRDF, Dietrich Rebholz said that his group would like to get the
triple store ready before supplying a SPARQL endpoint. I see the RDF
associated with CALBC as a potentially important resource for
experimenting with text-mined assertions and their RDF provenance. It
would also be interesting to see where the Annotation Ontology and
others from Scientific Discourse could help to disclose provenance for
CALBC. Below is the announcement of the latest CALBC challenge.

Dear List Member,

The CALBC project partners want to make you aware of the running
second CALBC challenge.

This challenge aims at creating a broadly-scoped and diversely
annotated biomedical text corpus (1 Million Medline abstracts on
immunology annotated with different semantic entities) by
automatically integrating the annotations from various named entity
recognition and concept identification systems. Our final goal is to
produce automatically a harmonized silver standard corpus in contrast
to a manually generated gold standard corpus. The first harmonized
corpus (silver standard) has already been generated successfully and
the first set of annotated documents is available (see

For this community-wide shared task, we strongly rely on your
expertise to get the best results possible, and thus to continuously
improve the silver standard corpus. We want to encourage you to take
part in the challenge and contribute either annotations from your own
annotation solutions or to reproduce the annotations based on the
annotated set of documents.

If you are interested, we kindly ask you to have a closer look at the
CALBC Flyer (http://www.ebi.ac.uk/Rebholz-srv/CALBC/CALBC_Flyer.pdf)

or simply check <http://www.calbc.eu> for further information.

With best regards,

the CALBC project partners
