Surface semantics from electronic medical records with knowledge graph technologies
In this talk, I will share our experience and lessons learnt from applying artificial intelligence technologies at several large UK hospitals, aiming at making health data available to understand disease and find ways to prevent, treat and cure them. I will introduce a health informatics toolkit - CogStack-SemEHR in transforming, integrating and analysing near real-time electronic medical records. This talk will give examples on how knowledge graph technologies are useful and necessary in surfacing semantics in applications of natural language processing and network analysis for answering clinical questions. It will end with discussions on challenges and our thoughts on future directions of knowledge graphs in healthcare.
