The SADI plug-in to IO informatics' sentient knowledge explorer

Integrating, visualizing and exploring Semantic Web data is the primary focus of the Sentient Knowledge Explorer (KE). To date, export of displayed data to arbitrary analytical tools has not been possible through the KE interface. Here we describe a plug-in to KE which allows selected data to be passed to appropriate SADI Semantic Web Services for analysis. Bootstrapping the semantics of a selected node is achieved through resolution of its URI to metadata; thereafter, utilizing the semantics in SADI service interface descriptions, only appropriate services are presented to the user. These services are then invoked by simple mouse clicks. Key to success is the recording of a SPARQL query in the SADI registry, allowing discovery of compatible services in environments that lack reasoning support.
