Abstract
Drug safety surveillance plays a significant role in supporting medication decision-making by both healthcare providers and patients. Extracting adverse drug events (ADEs) from social media provides a promising direction to addressing this challenging task. Prior studies typically perform lexicon-based extraction using existing dictionaries or medical lexicons. While those approaches can capture ADEs and identify risky drugs from patient social media postings, they often fail to detect those ADEs whose descriptive words do not exist in medical lexicons and dictionaries. In addition, their performance is inferior when ADE related social media content is expressed in an ambiguous manner. In this research, we propose a research framework using advanced natural language processing and deep learning for high-performance ADE extraction. The framework consists of training the word embeddings using a large medical domain corpus to capture precise semantic and syntactic word relationships, and a deep learning based named entity recognition method for drug and ADE entity identification and prediction. Experimental results show that our framework significantly outperforms existing models when extracting ADEs from social media in different test beds.
