BeFree is a text minning tool to unlock the information contained in biomedical documents. It is composed of the Biomedical Named Entity Recognition (BioNER) module based on dictionaries using fuzzy- and pattern matching methods to find and uniquely identify entity mentions in the literature, and a module for Relation Extraction (RE) based on Support Vector Machine (SVM). Relations between biomedical entities are recognized by exploiting syntactic and semantic information from the text.
We have applied BeFree for the identification of relationships between genes, diseases and drugs from the scientific literature. More information on the BeFree system can be found here.
