# 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](https://github.com/ieeta-pt/BioNExt) repository.
