Integration of Deep Learning and Traditional Machine Learning for Knowledge Extraction from Biomedical Literature

Abstract

In this paper, we present our participation in the Bacteria Biotope (BB) task at BioNLP-OST 2019. Our system utilizes fine-tuned language representation models and machine learning approaches based on word embedding and lexical features for entities recognition, normalization and relation extraction. It achieves the state-of-the-art performance and is among the top two systems in five of all six subtasks. c 2019 Association for Computational Linguistics.
