# RegEl PubMed Database

This database contains the annotations generated by running [HunFlair](https://github.com/flairNLP/flair/blob/master/resources/docs/HUNFLAIR.md) models trained on the [RegEl corpus](https://zenodo.org/record/5776679) over >20M PubMed abstracts.

By pairing these annotations with the one provided by PubTator this generates a large text mining database of regulatory elements associated with genes (normalized to NCBI Gene ids) and disease (normalized to either MeSH or OMIM).

The tables composing the database are:

* abstracts.db:
  - pmid = PubMed ID of the given abstracts
  - sid = sentence ID of the given abstracts (from 0 to # of sentences)
  - text = text of the given sentence

* gene.db and disease.db:
  - pmid = PubMed ID of the given abstracts
  - sid = sentence ID of the given abstracts (from 0 to # of sentences)
  - etype = entity type (enhancer, promoter, TFBS)
  - ann_text = mention of the regulatory element as found in the abstract
  - start = position (# character) in which the mention begins
  - end = position (# characters) in which the mention ends
  - score = model's confidence
  - cui = gene or disease identifier
  - cui_symbol = official symbol of cui (if available)
