SPARQL Endpoint set-up and load any twitter profile into the RDF Store

This weekend I optimized the triplification and annotation process for every twitter user. From now on it is possible to load any twitter user and store the annotated triples in the ARC2 TripleStore. A SPARQL endpoint allows querying

For now you can be load your own twitter account and associated tweets into the system with this url:

http://linkeddata.semanticprofiling.net/interlinking/provider.php?user=your_username

Contribute to the semantic web and do it NOW! 🙂 Any questions or extreme load times, I will be happily to look into and fix it!

The SPARQL Endpoint can be accessed on:

(In the picture: a triple) It’s a matter of preference and what you expect from the system. The most common opensource sytems that are widely in us as off May 2009 are listed are:

Is Twitter RDFization or triplification by Virtuoso usable?

The W3C lists many solutions for converting any non-rdf data to rdf data. After taking a closer look to the list, it became clear that there exists a very well documented system: Virtuoso Sponger. There is a broad support for many data sources. The architecture is very modular. This is realized by the use of so-called cartridges. I want to be sure that this promising middleware can support the framework I need. I investigated a twitter use case presented on a dedicated page. Since the architecture overview and the presentation about the mechanism is astonishing, my expectations were very high. Read more of this post
