ESWC2008 slides

I finally uploaded the slides of the various talks I gave at last ES(W)C in Tenerife:

As you can see, it was a busy but - once again - really valuable week. Lots of quality papers, especially, from my point of view, the ones about querying (esp. distributed approaches like DARQ - more details on Orri Erling’s blog), LOD-related (Semantic Sitemaps) and the OntoGame one. Readers of this blog should also be interested in xOperator, an approach combining LOD, social networking and instant messaging.

Interesting things were also presented during the workshops, as SWOOKI (a Semantic P2P wiki), ACEWiki (a wiki using controlled natural language to model both ontology and instances from the wiki, with reasoning capabilities using Pellet) and the use of semantic wikis for mathematics, which was particulary interesting from the use-case point of view, as for Flyspeck. Also nice (and sometimes fun) papers and demos in the SFSW workshop (congrats to Benjamin!) and in the demo session, as RDBToOnto that mine ontologies (and instances) from relational databases.

Another interesting fact for LOD-ers are the first steps of voiD, a vocabulary to describe datasets (which could efficiently combined with the previously mentioned work on distributed SPARQL: send your query on the Web, let the system find datasources, query and merge).

Finally, as in Beijing, it was a great opportunity to meet people I knew only online. Hope to see you in Karlsruhe!

IC2008: 19e Journées Francophones d’Ingénierie des Connaissances

Mercredi, jeudi et vendredi (18-19-20 Juin) auront lieu à Nancy (au LORIA plus pécisément) les 19e Journées Francophones d’Ingénierie des Connaissances, IC2008. Le programme annonce plusieurs présentations liées au Web Sémantique (aussi bien sur le lien Web 2.0 / WS - ou je parlerai notamment d’une utilisation combinée de SIOC, MOAT et de wikis sémantiques - que sur la conception et l’utilisation d’ontologies, requêtes ou webservices) et une keynote d’Ivan Herman intitulée “Etat des lieux du WS” aura lieu jeudi matin.

Toujours dans ce cadre d’IC2008 aura lieu demain l’atelier IC 2.0 que je co-organise. L’objectif principal est d’étudier les changements introduits par les usages du Web 2.0 dans les pratiques de gestion des connaissances. Les résumés des interventions sont en ligne, et là aussi le Web Sémantique est bien représenté.

Si vous êtes en Lorraine ces prochains jours et que ces sujets vous intéressent, vous savez ce qu’il vous reste à faire.

Fixig SMOB

Here are the scripts to fix the recent SMOB bug:

I remember a quote from Benjamin on #semsol (but I can’t find it in the logs - is there a related SPARQL endpoint ?) where he hoped that one day, people would consider RDF programming as ‘normal programming’. I think that SPARUL (especially at the triples level) is really helpful for that, since adding / deleting statements is more than easy. Combined with SPARQL capabilities and used, for instance, with ARC2 and its 3-lines-of-code endpoint, everyone should be able to go into SemWeb programming without aditional skills than the one required by usual PHP/MySQL applications.

Warning: SMOB bugfix

cc-ed on sioc-dev

If some of you are using SMOB publishing / aggregating tools [1],
please consider reading this.
The current prototype used sioc:MicroBlogPost class, while its URI in
SIOC spec is sioc:MicroblogPost.
I fixed it in SVN, but if you update some client or server now, it
won’t work with old data.
A patch to replace old URIs to new ones in existing applications will
be available soon.
But if you start developing code or implementing a server now, please
checkout the new svn code.

Sorry for any inconvenience !

Alex.
