The goal of the supporting resources for the BioNLP Shared Task 2013 is to provide the task participants with annotations from state-of-the-art automated tools in order to minimise the time-investment necessary to participate in the shared task and to allow for participants to experiment on how to leverage automated analyses provided by existing Natural Language Processing systems. In order to facilitate this, the shared task organisers issued an open call to the Natural Language Processing community for supporting resources.
Resources and Formats
This section describes the supporting resources that are available for the shared task. The files to be downloaded can be found at the bottom of the page.
BioC attempts to the address the BioCreative IV interoperability track and provides BioNLP ST 2013 participants with tokenisation, lemmatisation, sentence splitting, chunking and PoS-tagging in a unified BioC XML format to jump-start event extraction efforts.
In addition to the above resources BioC includes starter code in Java and C++ that demonstrates how to read and utilise the BioC XML data.
I you have questions regarding BioC, please see the BioC homepage and/or contact: Don Comeau (comeau <at> ncbi.nlm.nih.gov), Rezarta Islamaj (rezarta.islamaj <at> nih.gov), Haibin Liu (haibin.liu <at> nih.gov) and John Wilbur (wilbur <at> ncbi.nlm.nih.gov)

BioYaTeA is a term extractor developed by INRA. It is an extended version of YaTeA (Aubin and Hamon, 2006) adapted to the biomedical domain. The relevant extracted terms are noun-phrases. Participles and prepositional attachments are handled. BioYaTeA provides the term lemma, PoS-tags, internal syntactic structures (constituent analysis) and positions in the document. The output formats are the tabular format and XML-BioYaTeA format. The data for all tasks can be downloaded here.
BioYaTeA can be downloaded from the CPAN BioYaTea page.
YaTeA can be downloaded from the CPAN YaTeA page.
If you have any questions regarding BioYaTeA, please contact: Wiktoria Golik from INRA (wiktoria.golik <at> jouy.inra.fr) and/or Thierry Hamon from Lim&Bio (thierry.hamon <at> univ-paris13.fr)

Cocoa is a dense annotator for biological text and in addition to the automated annotations provided below it can be used through a web API described at npjoint.com. The annotations covers over 20 different semantic categories, among them macromolecules, chemicals, protein/DNA parts, complexes and organisms. The annotations are available in the brat stand-off format (.ann files) which for entity annotations is compatible with that of the BioNLP Shared Task 2013.
You can find the output from the Cocoa annotator downloads below with one archive for each task. Cocoa does not as-of-yet have a relevant publication to cite if you make use of the annotations, thus, please site the URL npjoint.com if you make use of the Cocoa system output for the shared task.
If you have any questions regarding Cocoa, please contact: S. V. Ramanan (ramanan <at> npjoint.com)
The application of syntactic analyses is common-place for Information Extraction (IE) systems. For this purpose, the organisers of the BioNLP Shared Task 2013 are providing some fundamental supporting resources in the form of sentence splitting, tokenisation and syntactic parses. The procedures used to generate these resources is identical to the one used in 2011 for the BioNLP Shared Task 2011 supporting resources, apart from upgrading the versions of the software used if a newer and improved version had been made available.
Please see the files below for checksums for all syntactic analyses files:
If you have any questions regarding the syntactic analyses, please contact: Pontus Stenetorp (pontus <at> stenetorp.se)
The full processing pipeline for the resources provided by the organisers is available here.
Sentence splitting pre-processing was done using the machine learning-based Genia Sentence Splitter (GeniaSS) and post-processed using a set of heuristics to correct common errors. The output format is a simple text format where sentences are separated by newlines.
Tokenisation was carried out using the GTB-tokenize.pl script that attempts to mimic the tokenisation used by the Genia Treebank. The output format is a simple text format where the syntactic tokens are separated by space.
