This is a few months late but better late then never! We said goodbye to PhD researcher Haklae Kim in May of this year when he returned to Korea and took up a position with Samsung Electronics soon afterward. We had a nice going away lunch for Haklae with the rest of the team from the Social Software Unit (picture below).
Haklae returned to Galway in September to defend his PhD entitled “Leveraging a Semantic Framework for Augmenting Social Tagging Practices in Heterogeneous Content Sharing Platforms”. The examiners were Stefan Decker, Tom Gruber and Philippe Laublet. Haklae successfully defended his thesis during the viva, and he will be awarded his PhD in 2010. We got a nice photo of the examiners during the viva which was conducted via Cisco Telepresence, with Stefan (in Galway) “resting” his hand on Tom’s shoulder (in San Jose)!
Haklae created a formal model called SCOT (Social Semantic Cloud of Tags) that can semantically describe tagging activities. The SCOT ontology provides enhanced features for representing tagging and folksonomies. This model can be used for sharing and exchanging tagging data across different platforms. To demonstrate the usage of SCOT, Haklae developed the int.ere.st open tagging platform that combined techniques from both the Social Web and the Semantic Web. The SCOT model also provides benefits for constructing social networks. Haklae’s work allows the discovery of social relationships by analysing tagging practices in SCOT metadata. He performed these analyses using both Formal Concept Analysis and tag clustering algorithms. The SCOT model has also been adopted in six applications (OpenLinkVirtuoso, SPARCool, RelaxSEO, RDFa on Rails, OpenRDF, SCAN), and the int.ere.st service has 1,200 registered members. Haklae’s research work was published in 2 journal articles, 15 conference papers, 3 workshop papers, and 2 book chapters. 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 Haklae 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.
Drupal creator Dries Buytaert wrote a very interesting and encouraging post last October entitled “Drupal, the Semantic Web and Search” in which he said: “On a social networking site built with Drupal, [semantic technology] opens up the possibility to do all sorts of deep social searches – searching by types and levels of relationships while simultaneously filtering by other criteria […] and if Drupal core supported FOAF and SIOC out of the box, you could search within your network of friends or colleagues. This would be a fundamentally new way to take advantage of your network or significantly increase the relevance of certain searches.” This was followed up with another post on Monday where Dries talked about some exciting possibilities for exposing the structured data that is available in many Drupal deployments, and the work that is ongoing to have RDFa available in Drupal 7 (read more in my RDFa and Drupal blog post from yesterday). There is also a great video which shows some use cases and examples for RDFa in Drupal.
Views Datasource is a set of plugins for the Drupal Views module for rendering node content in a number of shareable, reusable formats including RDF (FOAF, SIOC, and DOAP).
The Creative Commons Network has been launched, with CC CTO Nathan Yergler saying: “The CC Network is where the semantic rubber meets the web road. With the CC Network we’re leveraging everything we’ve learned over the past five years about metadata on the web, including the new RDFa standard, along with the work of many other groups, including FOAF, POWDER, and SIOC.”
