Concepts, Relations, and Queries in Biomedicine: The case for Semantic Search

Concepts, Relations, and Queries in Biomedicine: The case for Semantic Search

The language of biomedicine is varied and complex, with a plethora of surface variation, synonyms and name overloading occurring in a diversity of text types. In this talk I will explore the interaction between information extraction and information retrieval in the biomedical domain, arguing that normalization of concepts to ontologies and formal representation of relations is key to supporting effective retrieval of relevant texts in response to specific queries. I will further introduce some recent work that we have been doing on applying neural methods for biomedical information extraction tasks.
