Neural Biomedical Named Entity Normalization (Christopher Schiefer)

Methods for automatic information extraction from vast amounts of unstructured text become highly necessary due to the rapid growth of the biomedical literature. It is essential to identify biomedical entities in text documents in an automated way to enable tasks like searching for specific entities, providing document background information and linking similar documents. The process of linking a text mention to a specific entity identifier is called named entity normalization (NEN) or entity disambiguation. Previous approaches in the biomedical domain have been based on sets of manual rules, large dictionaries, and pre-defined features that are supposed to capture the knowledge of experts. In other domains, however, deep learning approaches have been able to outperform these traditional approaches significantly. We present a novel approach that leverages word embeddings as well as the latest improvements in biomedical Named Entity Recognition (NER) for the normalization of genes and compare it to state-of-the-art baseline approaches.
