The GAAIN entity mapper: Towards practical medical informatics application

Abstract

We discuss our work in progress towards the practical application of a system we have developed for automated schema mapping of medical datasets. While starting with a purely knowledge-driven approach to the schema mapping problem, based on information in data dictionaries, we are now incorporating machine-learning classification for determining mappings. We are further integrating the mapping system into a production medical informatics environment. We discuss our ongoing approach and progress in these areas, as well as current challenges.
