Google have recently launched http://research.google.com that will provide information on research activities at Google. There’s a series of video talks that are associated with these research activities.
This is a talk by Eyal Oran, Sebastian Kruk and Stefan Decker entitled “Semantic Web”.
Our development group has been doing a lot of semantic web related work here at Talis, in fact we have built a semantic web platform that we have built several applications upon, so the entire research area is something we are all very passionate about.
The talk covers some of the basic principles of the Semantic Web but also takes about FOAF, RDF and introduces ActiveRDF:
an object-oriented API for managing RDF data. ActiveRDF can be used with different RDF stores and integrates with Ruby on Rails. An addition to ActiveRDF is BrowseRDF, a faceted metadata browsing library. Faceted browsing is a natural technique for navigating that graph. We developed an expressive faceted interface that allows navigating arbitrary semi-structured data and formally show the improvement over existing interfaces.
I found the talk quite interesting, and it’s given me a fair bit to think about.
