I recently attended the Conference on Semantics in Healthcare and Life Sciences (CSHALS), in Cambridge, MA. The CSHALS meeting was a change for me in that it’s much more healthcare-oriented than other venues in which I’ve presented work from Phenoscape. This was a great opportunity to see how far the healthcare community has pushed semantic web technologies, and also to become more familiar with some of the more commercial packages which are available for storing and querying very large knowledgebases based on RDF (for example, AllegroGraph and Gruff from Franz, Inc., and Sentient Knowledge Explorer from IO Informatics). A particularly interesting talk was the keynote by Toby Segaran, of Metaweb Technologies, advocating semantic techniques as a more agile approach to data. Slideshows from the conference presentations are available for download here, including my own.
