Data integration is a crucial task in the biomedical domain. Data elements (DEs) play an important role in data integration and we propose to map DEs to terminological resources as an approach to data integration. We extracted DEs from eleven disparate biomedical sources. We compared these DEs to concepts and/or terms in biomedical controlled vocabularies and to reference DEs. We also exploited...

We outline our approach and rendering techniques and also discuss the relationship and relevance of our techniques to illustrative visualization.
