FINAL CALL FOR PARTICIPATION

BioCreative IV CHEMDNER Task: Chemical compound and drug name recognition
task

Task webpage: http://www.biocreative.org/tasks/biocreative-iv/chemdner/

=============================

We are pleased to announce that the CHEMDNER task development data set has
been released.


CHEMDNER  OVERVIEW

There is an increasing interest to facilitate more efficient access to
information on chemical compounds and drugs (chemical entities) described
in repositories of scientific articles and abstracts.



The goal of this task is to promote the implementation of systems that are
able to detect mentions of chemical compounds and drugs, in particular
those chemical entity mentions that can be subsequently   linked to a
chemical structure, rather than other macromolecules like genes and
proteins that had been already addressed in previous BioCreative efforts.



We invite participants to submit results for the CHEMDNER task providing
predictions for:

a) Given a set of documents, return for each of them a ranked list of
chemical entities described within each of these documents [Chemical
document indexing (CDI) sub-task]

b) Provide for a given document the start and end indices corresponding to
all the chemical entities mentioned in this document [Chemical entity
mention (CEM) recognition sub-task].

For these two tasks the organizers released both a training and a
development data set, each consisting in 3500 PubMed abstracts exhaustively
annotated manually by chemical domain experts following carefully developed
annotation guidelines.



CHEMDNER TASK RESOURCES

*Training set:         3500 manually annotated PubMed abstracts for
chemical entity mentions.

*Development set: 3500 manually annotated PubMed abstracts for chemical
entity mentions.

*Test set:              will consist in 3000 manually annotated PubMed
abstracts for chemical entity mentions.

*Evaluation scripts: scripts that can be used to evaluate performance of
automated systems.

*Annotation guidelines: detailed document describing the used manual
annotation criteria.

*Frequently asked question (FAQ): list of questions posed by registered
teams.

*Useful resource collection: compendium of useful software and lexical
resources/data for the task.



Based on the participating systems performance a selected number of teams
will be invited to submit

a manuscript for a special journal issue on the CHEMDNER task.
