[esip-semanticweb] [Esip-discovery] time for new challenges?

Thu Jan 3 10:40:08 EST 2013

I admit to being slow to see how servicecasting would solve our search engine discovery problem, but after running across the Google video about their Knowledge Graph (http://www.youtube.com/watch?v=mmQl6VGvX-c), I think I am finally starting to see the light:

Instead of attacking Search Engine Optimization in the tradional way, maybe we should target the knowledge graph efforts of Bing and Google.  That is, make our information available in a way that the knowledge graph picks it up.  Hence the inclusion of Semantic Web group in this message.

If we go that way, there are several things we need to understand about how Google/Bing consume semantic web information, e.g.:
a) encoding: RDF/XML, RDFa or something else?
b) data model:  what classes and/or properties are the search engines paying attention to?
c) graph traversal:  how and how far do the engines traverse the graph for any given search or result?
d) instance preferences:  are there particular instance entities that search engines weight preferentially?

Note that this implies that we solve the hooking of service casting to data with linked open data as a component of the solution...don't know if that is currently on the radar screen, but my impression from hearing Brian Wilson talk about publishing LOD is that it is on the radar for servicecasting.

Also, taking this LOD approach has benefits outside of Search Engine Optimization.  It might even be possible to take off from what we learn from the ToolMatch effort.

I think we made huge strides in this area over the last couple of years.  Yes there are a few issues - crawl frontier management and the data equivalent of page rank being the major issues; but other than that we have demonstrated the ability to find getCapabilities docs, OSDD's, web enabled folders, OAI-PMH catalogs, etc. wherever they are on the web.  And building a Google for data is a major interest of mine.  I've even come up with what I think could be that killer app - though I am totally uninterested in starting a startup, even if Boulder is a hub for doing that (yes, it is a cheap for pay kind of idea).
