The first day at the International Semantic Web Conference consisted of 8 workshops and 3 tutorials. I was one of the main organizers of the Consuming Linked Data (COLD) Workshop and therefore, I wasn’t able to attend any other event. I’m very happy to announce that we had a successful workshop, with over 60 attendees, a keynote by Prof Daniel Miranker from the University of Texas at Austin, 10 papers, 2 System papers and 2 vision papers.
Prof Miranker’s keynote was about removing the potholes in the road to the Semantic Web. The take home message was that Semantic Web Technologies must easily interoperate with existing systems and technologies and that we need to reach out to the larger development community.
The main topics presented in the papers were about visualization, querying and analysis of Linked Data. It is very exciting to see people working on ways to visualize the content of a linked data set. For example, Professor Jeff Heflin from Lehigh University presented a system that can visualize DBpedia content in a Tag Cloud Browser.
Querying linked data was also a hot topic, having presentations about linked traversal querying approach and query federation with vOID. There was a call to owners of linked data to publish more vOID descriptions in order for query federation to be more effective. Another topic was about how to analyze the contents of a RDF dataset in order to know how to query it.
There were two vision papers, one on Linked Closed Data and other on Linked Green Data. The Linked Closed Data paper made people think about what to do when you are integrating open data with restricted closed data. Linked Green Data expressed the need to publish “clean” and “unpolluted” data.
After the COLD workshop, we had three presentations for the Linked Data-a-thon, a hack-a-thon style event with the objective of creating an application that consumed Linked Data in 2 weeks. The applications that were submitted consumed the ISWC metadata and will offer conference attendees different ways of navigating the conference data. The winner of this competition will be announced on Thursday.
Overall, the Linked Data day was a fantastic event. And this was just Day 1!
