BIGNER

- Background Information driven Gene Named Entity Recognizer


 

Overview

This tool is able to locate gene/protein names in biomedical literature. The core of the system is a dictionary generated by semi-supervised learning from a large amount of unlabeled biomedical texts [1]. Two appoaches are provided: (a) maximum match based on the dictionary. (b) The combination of the dictionary and a conditional random field (CRF) model. You can test it with your own sentences on the demo page.
