Model Card for BioNExt

BioNExt, is an end-to-end Biomedical Relation Extraction and Classifcation system. The work utilized three modules, a Tagger (Named Entity Recognition), Linker (Entity Linking) and an Extractor (Relation Extraction and Classification).

This repositories contains two models:

  1. Tagger: Named Entity Recognition module, which performs 6 class biomedical NER: Genes, Diseases, Chemicals, Variants (mutations), Species, and Cell Lines.
  2. Extractor: Performs Relation Extraction and classification. The classes for the relation Extraction are: Positive Correlation, Negative Correlation, Association, Binding, Drug Interaction, Cotreatment, Comparison, and Conversion.

For a full description on how to utilize our end-to-end pipeline we point you towards our GitHub repository.
