Data Integration through data elements: Mapping data elements to terminological resources
نویسندگان
چکیده
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 DE values to disambiguate underspecified DEs. Results suggest that data integration can be achieved automatically with limited precision and largely facilitated by mapping DEs to terminological resources. Finally, the use of general lexical resources and of more powerful techniques to exploit DE values would improve our method.

Mapping clinical phenotype data elements to standardized metadata repositories and controlled terminologies: the eMERGE Network experience
BACKGROUND Systematic study of clinical phenotypes is important for a better understanding of the genetic basis of human diseases and more effective gene-based disease management. A key aspect in facilitating such studies requires standardized representation of the phenotype data using common data elements (CDEs) and controlled biomedical vocabularies. In this study, the authors analyzed how a ...
متن کاملResolving Semantic Heterogeneity in Databases with a Terminological Model: Correspondence Refinement
The success of schema integration in multidatabase systems relies heavily on the determination of complete and refined correspondence relationships between them. So, the candidate schemas to be integrated must be rich and precise semantically, i.e., each of their data elements must be sufficiently defined for to be distinguished from others or identified to some of them. Our schema integration ...

Value Stream Mapping technique involves flowcharting the steps, activities, material flows, communications, and other process elements that are involved with a process or transformation. In this respect, Value stream mapping helps an organization to identify the non-value-adding elements in a targeted process and brings a product or a group of products that use the same resources through the ma...
