sd-geneprod-roles

Model description

This model is a RoBERTa base model that was further trained using a masked language modeling task on a compendium of English scientific textual examples from the life sciences using the BioLang dataset. It was then fine-tuned for token classification on the SourceData sd-nlp dataset with the GENEPROD_ROLES configuration to perform pure context-dependent semantic role classification of bioentities.

Intended uses & limitations

How to use

The intended use of this model is to infer the semantic role of gene products (genes and proteins) with regard to the causal hypotheses tested in experiments reported in scientific papers.

To have a quick check of the model:

python

from transformers import pipeline, RobertaTokenizerFast, RobertaForTokenClassification
example = """<s>The <mask> overexpression in cells caused an increase in <mask> expression.</s>"""
tokenizer = RobertaTokenizerFast.from_pretrained('roberta-base', max_len=512)
model = RobertaForTokenClassification.from_pretrained('EMBO/sd-geneprod-roles')
ner = pipeline('ner', model, tokenizer=tokenizer)
res = ner(example)
for r in res:
    print(r['word'], r['entity'])

Limitations and bias

The model must be used with the roberta-base tokenizer.

Training data

The model was trained for token classification using the EMBO/sd-nlp dataset which includes manually annotated examples.

Training procedure

The training was run on an NVIDIA DGX Station with 4XTesla V100 GPUs.
