Another successful defense by Uldis Bojars in November

Uldis Bojars submitted his PhD thesis entitled “The SIOC MEthodology for Lightweight Ontology Development” to the University in September 2009. We had a nice night out to celebrate in one of our favourite haunts, Oscars Bistro.

This was followed by a successful defense at the end of November 2009. The examiners were Chris Bizer and Stefan Decker. Uldis even wore a suit for the event, see below.

I will rule the world!
I will rule the world!

Uldis established a formal ontology design process called the SIOC MEthodology, based on an evolution of existing methodologies that have been streamlined, experience developing the SIOC ontology, and observations regarding the development of lightweight ontologies on the Web. Ontology promotion and dissemination is established as a core part of the ontology development process. To demonstrate the usage of the SIOC MEthodology, Uldis described the SIOC project case study which brings together the Social Web and the Semantic Web by providing semantic interoperability between social websites. This framework allows data to be exported, aggregated and consumed from social websites using the SIOC ontology (in the SIOC application food chain). Uldis’ research work has been published in 4 journal articles, 8 conference papers, 13 workshop papers, and 1 book chapter. The SIOC framework has also been adopted in 33 third-party applications. The Semantic Radar tool he initiated for Firefox has been downloaded 24,000 times. His scholarship was funded by Science Foundation Ireland under grant numbers SFI/02/CE1/I131 (Líon) and SFI/08/CE/I1380 (Líon 2).

We wish Uldis all the best in his future career, and hope he will continue to communicate and collaborate with researchers in DERI, NUI Galway in the future.

Tales from the SIOC-o-sphere #7

20080403a.png It’s been three months since my last round-up of all things SIOC-ed, so here is entry number seven in the series:

Kingsley remixes my DataPortability slides as "Data Accessibility and Me: Introducing SIOC, FOAF and the Linked Data Web"

Kingsley Idehen told me on IRC that he remixed my presentation on DataPortability and SIOC from yesterday as Data Accessibility and Me: Introducing SIOC, FOAF and the Linked Data Web.

I’ve never had my slides remixed before, I’m honoured! Here’s the new version:

Semantic Web for Dummies

20080220a.jpg I referenced this on the SIOC-Dev mailing list recently, and when I pasted it on the DataPortability.org steering group chat this morning (in parallel with our first phone conference), Drummond Reed suggested I blog it. It’s originally from MIT’s Stefan Marti:

XML customised tags, like:
+ RDF relations, in triples, like:
(Nena) (is_dog_of) (Kimiko/Stefan)
+ Ontologies / hierarchies of concepts, like:
mammal -> canine -> Cotton de Tulear -> Nena
+ Inference rules like:
If (person) (owns) (dog), then (person) (cares_for) (dog)
= Semantic Web!

int.ere.st – create and share tags across your online communities

As mentioned in a previous blog post, int.ere.st has just launched. The main objective of int.ere.st is to demonstrate how Semantic Web and Web 2.0 technologies can be combined to provide better metadata creation and sharing support across various online communities.

With int.ere.st, you can save, tag and bookmark your own as well as other people’s tag clouds, as represented using the SCOT ontology. The tag meta search also allows you to look for similar patterns of tagging from other people based on their interests (as expressed using tags).

Some functionalities of int.ere.st include:

  • Various options for tag searching, such as and (&), or (space), co-occurrence (+), broader (>), and narrower (< )
  • User searching
  • Resource searching
  • Integrating tagged data across communities
  • Meta tagging
  • Ontology bookmarking
  • Sharing metadata produced using the FOAF, SIOC, and SCOT ontologies

You can try it at out at http://int.ere.st/. Here are some video demos of int.ere.st in action, and some more videos are forthcoming:



State of the SIOC-o-sphere (#5)

It’s that random time of the year again where I summarise what’s been going on in the world of SIOC

Testing Yahoo! Pipes

Yes, it’s very cool! RSS fans, prepare to be blown away. Via this Slashdot article and CaptSolo’s post on sioc-dev:

“Yahoo has introduced a new product called Pipes. It seems to be a GUI-based interface for building applications that aggregate RSS feeds and other services, creating Web-based apps from various sources, and publishing those apps. Sounds very cool. TechCrunch has a decent write-up, and Tim O’Reilly is all over it. The site was down for a few hours and is just back up. Has anybody tried this?”

and from the Pipes page:

Pipes is an interactive feed aggregator and manipulator. Using Pipes, you can create feeds that are more powerful, useful and relevant.

So I created a basic pipe to take three feeds from Planet Journals, IrishBlogs.ie and awards.ie about the forthcoming Irish Blog Awards using the “Fetch” module. I then used their “For Each: Annotate” module to add a sioc:topic annotation, using the first matching result from a Yahoo! search for the phrase “Irish Blog Awards”. The graphical interface is very easy to use, and a screenshot of the pipe construction is shown on the left. You can see the pipe output on the right below; unfortunately the RSS 2.0 dump loses the sioc:topic annotation I added, but the JSON dump still retains it so with a bit of manipulation this could provide the appropriate RDF.


Buxon visor for sioc:Forum browsing

I’ve been testing out the Buxon visor for browsing SIOC forums, created by the SWAML developers and written in PyGTK.

So far, it works great (with SWAML-generated data). I used an example script packaged with python-libgmail (archive.py) to download an inbox from a GMail account (subscribed to the sioc-dev mailing list) to mbox format, and then ran swaml.py on that mbox to convert it to SIOC RDF. The resulting RDF is here, and I successfully browsed this with Buxon (as shown in the screenshot below). Great job, SWAML guys!

This is a nice demonstrator, and it just remains to do the same for a few more SW-related mailing lists…
