Biomedical Corpora
A collection of annotated, freely distributable, biomedical corpora, which can be used for training supervised machine learning methods for various tasks in biomedical text-mining and information extraction.
All corpora are provided in corpora. They are divided into subdirectories NER, for corpora which can be used to train named entity recognition (NER) solutions, and Relation Extraction, for corpora which can be used to train relation/event extraction solutions. Corpora are provided in both a CoNLL-like format and a Standoff format.
Most corpora in the CoNLL-like format were originally collected here. In many cases, the tags were mapped to 4-letter codes:
| Old tag | New tag |
|---|---|
Chemical, Simple_chemical |
CHED |
Disease |
DISO |
Organism, Species, NCBITaxon, Taxon |
LIVB |
Cellular_component |
COMP |
Cell, cell_type |
CLTP |
cell_line |
CLLN |
Gene, Protein, Gene_or_gene_product, GGP |
PRGE |
Mappings were largely inspired by this API.
Corpora names (loosely) follow the naming scheme: <corpus_name>_<entity>_<tagset>.
Download
To download the corpora, simply clone the repository locally:
$ git clone https://github.com/BaderLab/Biomedical-Corpora.git
Or click the green Clone or download button and select Download ZIP.
Resources
https://github.com/spyysalo provides many useful repositories for working with these corpora. Many of the most popular corpora have their own repositories (e.g. S800, NCBI-Disease) which contain code for collecting the corpus from its original source and converting it into a format suitable for training a machine learning classifier (e.g. CoNLL or Standoff).
