Ivan Herman, Semantic Web Activity Lead at the World Wide Web Consortium (W3C) and member of the W3C Team, gave a presentation at the fourth annual 2008 Semantic Technology Conference about the state of the semantic web on the 18th of May in San Jose, California.
The 55 page presentation is publicly available at Ivan Herman’s website (under Creative Commons license).
The structure of the presentation:
So where are we with the Semantic Web?
- We have the basic technologies
- Lots of Tools (not an exhaustive list!)
- There is a great community
- Some deployment communities
So what is the Semantic Web?
A few words about “newer” technologies
- Querying RDF: SPARQL
- The power of CONSTRUCT
But: how do you get the data on the SW?
- Public datasets are accumulating
- How to get RDF data?
- Bridge to relational databases
- Linking Open Data Project
- Example data source: DBpedia
- Structured data from Wikipedia
- Automatic links among open datasets
- Data may be around already…
- Data may be extracted (a.k.a. “scraped”)
- Getting structured data to RDF: GRDDL
- Getting structured data to RDF: RDFa
- Such data can be SPARQL-ed
- SPARQL as a unifying point!
- How to “assign” RDF data to resources?
- The data might be embedded
- POWDER
Everything has not been solved…
- Some open technical issues
- Other items: naming
- A major problem: messaging
Some of the usual misconceptions…
- SW Ontologies ≠ a central, big ontology!
- Web 2.0 and SW are no enemies…
- Semantic Web ≠ academic research only
