Semantic Composition of Disparate Data in GeoHealthUS for Navigation, Display and Analysis

GeoHealth US Corp produces environmental monitoring data in the United States, and aggregates that data with historical environmental data from US Government sources. Data sources include five programs that track pollution history at the US Environmental Protection Agency, and air quality data collected by GeoHealth US Corp itself. Environmental monitoring data is combined with information from the US Department of Health & Human Services, including the US National Library of Medicine, to automatically associate environmental conditions with diseases and symptoms. Semantic Web techniques are used to perform the data integration, navigate the data for analysis, and to drive the display of contextually relevant data in a Web user interface. GeoHealth US Corp is a Virginia Benefit Corporation (or “B-corporation”), a for-profit corporate entity that includes positive impacts on society and the environment in its core mission.
