Flickr Machine Tags

Flickr have added an interesting new feature to their query API, Machine Tags. In one way, this is really a formalisation of what people were already doing to a certain extent informally. What is seems like to me is a step toward RDF (at the moment there’s only support for literal values as objects)

IBM Adtech Group release RDF Repository

As I mentioned a couple of weeks ago, the IBM Advanced Technology Group we visited at Cambridge have been putting some serious development effort into their Semantic Layered Research Platform.
Wing reported yesterday that Boca, an RDF repository built atop DB2, has gone public in the platform’s first OS release. I’ve already downloaded, can’t wait […]

Under the Radar

On Saturday, wrapping up our time in San Francisco, Ian and I had a great informal meet up with Nova Spivack and some of his team at Radar Networks. We showed them some the things we’ve been working on and demoing for the past few months, talked a bit about the Talis Community Licence […]

Enterprise 2.0 Mashups

Marc Benioff, CEO of Salesforce.com is on stage now. He makes the claim that Salesforce are doing for enterprise services what Amazon is doing for infrastructure, i.e. removing the “muck” and enabling innovation. He characterises one aspect of salesforce as an “Elastic Database, that scales” and in that regard, I can see a lot of […]

ISWC2006 Pt II

Last night Ian and I met up with Harry Halpin, chair of the GRDDL working group and hit downtown Athens. First up, some grub at The Last Resort Grill with a party of semwebbers including Guus Schreiber and Fabio Ciravegna then on to the nearby Transmetropolitan. A good night was had by all with plenty […]

Relevancy Ranking For RDF

ReConRank: A Scalable Ranking Method for Semantic Web Data with Context (pdf) Aidan Hogen, Andreas Harth, Stefan Decker
This paper presents a way of transforming the results of a text query over a set of indexed RDF data into a directed graph and making it suitable for ordering using PageRank-like relevancy ranking. The cool thing here […]

OWL as Constraint Definition

Adding Constraints to OWL, Boris Motik University Of Manchester
Compares database constraint definition with OWL as in lots of cases we want to use owl like db constraints, rather than solely for inferencing.
Interesting idea as OWL provides a very rich schema definition language such as hierarchies/memberships/restrictions etc.
Proposes a notion of extended OWL Knowledge bases where […]

ISWC2006 Athens, Georgia

Day one of ISWC2006 and we’re in the Scalable Semantic Web Knowledge Base Systems (SSWS 2006) workshop.
The workshop format means that a lot of information is compressed into a relatively short time, so I’ve only managed to digest selected bits so far and jot down a few rough thoughts about some of the presentations for […]

Georgia on my mind

We’ve just arrived in Georgia for the second leg of our whistlestop tour of the US, 2 days at ISWC2006. We flew into Atlanta, picked up a car and drove out to Athens via I-85 & GA316. I took a few miles to get used to the automatic gearbox and the driving on the […]
