Stefan Audersch: Semantic Web technologies for visual exploration and fusion of multivariate data
[I missed the first few minutes]
It’s about data integration in a network of small companies and research institutes. They want to share medical and biological data.
Their system integrates data from two organizations. The data lives in a MySQL database. They describe the database schema with RDF, using Sesame. They expose a web service interface to the client.
On the client, a user can build a “workflow” consisting of data sources, “Semantic Joins” on primary keys, and various display/rendering/visualization modules. The RDF descriptions of the databases are used in the workflow builder, e.g. for checking the workflow for errors.
They have performance problems and hope to improve them by using parallelization.
Very interesting talk; I don’t do it justice with this poor summary. I’m looking forward to reading the paper.
