The first task of the BioASQ challenge (Task1a: Large-scale online biomedical semantic indexing) started on Monday 22th of April, 2013. To make the participation easier, the task has been divided into three consecutive periods (batches) of 6 weekly tests each. Separate winners will be announced for each batch. Participation in the task can be partial, i.e. in some of the batches and some of the weekly tests.
Prizes will be awarded to the winners of each batch. Check the following page for more information: http://www.bioasq.org/participate/prizes
Each week, a new test set will be released. After downloading the test set, participants will have to respond in limited time with the indexes of the MeSH terms that their systems estimated.
Registration to the task is open and will remain open until the end of the challenge in August. In order to register and participate, please visit the BioASQ participants area: http://bioasq.lip6.fr/.
