I gave a talk on “Using Semantics to Improve Corporate Online Communities” yesterday at the COIN@MALLOW workshop. The talk was mainly based on the work done during my Ph.D. thesis, demonstrating how to manage and combine various layers of semantics on the top of Enterprise 2.0 ecosystems and let users create and take advantage of the related semantic annotations. Here are the slides of the talk.

It has been announcedin the past few weeks but I didn’t really blog about it so far. We’re hosting a second edition of the Social Data on the Web (SDoW) workshop at the next ISWC2009 in Washington. Here’s the call for papers (longer version here).
The 2nd Social Data on the Web workshop (SDoW2009) co-located with the 8th International Semantic Web Conference (ISWC2009) aims to bring together researchers, developers and practitioners involved in semantically-enhancing social media websites, as well as academics researching more formal aspect of these interactions between the Semantic Web and Social Web.
Since its first steps in 2001, many research issues have been tackled by the Semantic Web community such as data formalism for knowledge representation, data querying and scalability, or reasoning and inferencing. More recently, Web 2.0 offered new perspectives regarding information sharing, annotation, and social networking on the Web. It opens new research areas for the Semantic Web which has an important role to play to lead to the emergence of a Social Semantic Web that should provide novel services to end-users, combining the best of both Semantic Web and Web 2.0 worlds. To achieve this goal, various tasks and features are needed from data modeling and lightweight ontologies, to knowledge and social networks portability as well as ways to interlink data between Social Media websites, leveraging proprietary data silos to a Giant Global Graph.
Following the successful SDoW2008 workshop at ISWC2008, SDoW2009 aims to bring together Semantic Web experts and Web 2.0 practitioners and users to discuss the application of semantic technologies to data from the Social Web.
The workshop welcome submission of short and full papers as well as demos of applications combining Semantic Web and Social Web technologies – all due to the 10th of August.
Je soutiendrai ma thèse “Technologies du Web Sémantique pour l’Entreprise 2.0” le mardi 9 Juin à 10h30 à la Maison de la Recherche, 28 rue Serpente, Paris.
Les travaux présentés dans cette thèse proposent différentes méthodes, réflexions et réalisations associant Web 2.0 et Web Sémantique. Après avoir introduit ces deux notions, nous présentons les limites actuelles de certains outils, comme les blogs ou les wikis, et des pratiques de tagging dans un contexte d’Entreprise 2.0. Nous proposons ensuite la méthode SemSLATES et la vision globale d’une architecture de médiation reposant sur les standards du Web Sémantique (langages, modèles, outils et protocoles) pour pallier à ces limites. Nous détaillons par la suite différentes ontologies (au sens informatique) développées pour mener à bien cette vision : d’une part, en contribuant activement au projet SIOC – Semantically-Interlinked Online Communities -, des modèles destinés aux méta-données socio-structurelles, d’autre part des modèles, étendant des ontologies publiques, destinés aux données métier. De plus, la définition de l’ontologie MOAT – Meaning Of A Tag – nous permet de coupler la souplesse du tagging et la puissance de l’indexation à base d’ontologies. Nous revenons ensuite sur différentes implémentations logicielles que nous avons mises en place à EDF R&D pour permettre de manière intuitive la production et l’utilisation d’annotations sémantiques afin d’enrichir les outils initiaux : wikis sémantiques, interfaces avancées de visualisation (navigation à facettes, mash-up sémantique, etc.) et moteur de recherche sémantique. Plusieurs contributions ont été publiées sous forme d’ontologies publiques ou de logiciels libres, contribuant de manière plus large à cette convergence entre Web 2.0 et Web Sémantique non seulement en entreprise mais sur le Web dans son ensemble.
La soutenance est publique, si le sujet vous intéresse, n’hésitez pas !
Le mémoire et les slides seront également postés sur ce site par la suite.
We just made some changes to the SIOC Core ontology and to the related modules:
- Added OWL-DL compliance statements for SIOC Core and the Types / Access / Services modules
- Edited owl:disjointWith statements for some classes of SIOC Core
- Removed domain of sioc:note
- Removed domain of sioc:has_owner and range of sioc:owner_of
- Defined sioc:account_of as inverse property of foaf:holdsAccount
- Defined sioc:avatar as a subproperty of foaf:depiction
So, SIOC is now OWL-DL !
This change was motivated by the current SWANSIOC integration project that will be introduced during the upcoming ISWC tutorial on Semantic Web for Health Care and Life Sciences.
The SIOC Core Ontology Specification has been updated according to the changes.
The other good news regarding SIOC is that Yahoo! SearchMonkey now supports (and recommends !) it in its developer documentation. Moreover, in case you did not already read it, John published the Tales from the SIOC-o-sphere #8 about two weeks ago.
More generally, if you want to join the SIOC community, by developing new applications or APIs, or if you request some help regarding implementing SIOC in your existing tools, feel free to come on #sioc on irc.freenode.net or ask on the sioc-dev ML.
Gautier (aka lespetitescases) just hacked his SMOB client to make it post on identi.ca as well as on twitter. He’s using the new laconica API combined with the same method that SMOB uses at the moment to post on twitter (CURL + HTTP-Auth). As this feature was on the TODO list and some people were asking for it (a thread was also started by John recently on both SIOC and identi.ca mailing-lists) that was a really great news !
I just added those changes to the SMOB client (get it or update from svn) , so that it can now be used to post on identi.ca ! Moreover, I added the ability to post not only on identi.ca but on any laconi.ca based microblogging platform. You’ll see news parameter in the config_dist.php file, that let you set-up a list of servers with dedicated user / pass, as follows. Then, when publishing an update, you’ll be able to choose those servers as well as the previous ones (including twitter), and enjoy multiple-posting:
Then it’s browsable everywhere, but you still own it locally as RDF data so that you can re-use it later, etc.
Once again, merci Gautier !
The SDoW deadline have been extended to the 4th of August, so that you have two additional weeks to submit your paper, demo or poster.
The 1st Social Data on the Web workshop (SDoW2008) co-located with the 7th International Semantic Web Conference (ISWC2008) aims to bring together researchers, developers and practitioners involved in semantically-enhancing social media websites, as well as academics researching more formal aspect of these interactions between the Semantic Web and Social Media.
Complete details about the workshop can be found on its website. Also note that the poster and demo submissions can be up to 3 pages in LNCS format, while it was 2-pages only at the begining.
I finally uploaded the slides of the various talks I gave at last ES(W)C in Tenerife:
- “FOAF and SIOC applications”, invited talk at Harry Halpin’s “Social Networks” tutorial (embeds at the end of that post)
- “MOAT: Meaning Of A Tag”, lightning talk at the LOD BOF
- “Towards and Interlinked Semantic Wiki-Farm”, SemWiki2008 (paper will be online later on the workshop proceedings and was awarded best paper – thanks for the kiwis )
- “Microblogging: A Semantic Web and Distributed Approach”, SFSW2008 (paper)
- “Social Network Portability panel introduction”
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!
