Even more LiU Research at ISWC 2016 – Ontology Design Patterns

In addition to the work mentioned in a previous post about ISWC, the LiU Semantic Web research team has also been very active in the Ontology Design Patterns (ODPs) sub-community at ISWC.

On Monday (October 17), Karl Hammar co-arranged the tutorial session Ontology Design Patterns for Linked Data Publishing. The tutorial was very well-received, with over 30 participants learning about ODP theory and practice, and evaluating Karl’s XD for WebProtégé ODP tooling.

On Tuesday (October 18), Karl also co-arranged the 7th Workshop on Ontology and Semantic Web Patterns, at which he also presented two papers: Template-Based Content ODP Instantiation and How to Document Ontology Design Patterns. In total there were twelve presentations given at the workshop, two keynote talks, and a town hall meeting discussing future directions of research and other issues of weight to the ODP community. Approximately 25 people attended the workshop, and the quality of the work presented and of the subsequent discussions was excellent.

Hannes Ebner (MetaSolutions AB) will talk in the LiU Semantic Web Seminars Series

HannesEbnerOn Monday next week, October 31, Hannes Ebner of MetaSolutions AB will give a talk in our series of Semantic Web seminars. The title of his talk is:

From Research to Business – Enabling Agile Information Management with Linked Data

Abstract: MetaSolutions was founded in 2011 as a spin-off from research on Web Architecture and Linked Data. Even today the Linked Data technology stack builds the foundation of the company’s product platform that allows organisations to manage their information in a more agile way. Hannes Ebner, one of the two founders, will talk about how a product emerged from research prototypes, which common business problems the company tackles, and how the application of Linked Data became a competitive advantage.

Time and date: 11am, October 31, 2016

Location: Campus Valla, Building B, Room “Charles Babbage”

LiU Semantic Web research at ODBASE 2016

ODBASE_smallWe have two research papers in the 15th Int. Conference on Ontologies, Databases, and Applications of Semantics (ODBASE 2016) to take place this week in Rhodes, Greece. These papers are:

  • “Bindings-Restricted Triple Pattern Fragments” by our Olaf Hartig and Carlos Buil-Aranda from the Universidad Tecnica Federico Santa Maria, Chile–read an extended preprint of this paper and check out the Web page for the paper.
  • “Scheduling Refresh Queries for Keeping Results from a SPARQL Endpoint Up-to-Date” by Magnus Knuth (Hasso Plattner Institute, Potsdam, Germany), Olaf Hartig, and Harald Sack (Hasso Plattner Institute)–check out the preprint of this paper or the extended version which provides more details about the characteristics of the experimental data, and there is also a Web page with the experimental data.

Olaf Hartig will attend the conference and present the first of these papers. He will be happy to talk to you if you also happen to be in the conference.

Best Poster Award at ISWC 2016

ISWC2016BestPosterWe are very happy to announce that Olaf Hartig has won the Peoples’ Choice Best Poster Award at the 15th International Semantic Web Conference (ISWC 2016), which is the main conference in our field. The research presented on the poster is joint work with Carlos Buil-Aranda from the Universidad Tecnica Federico Santa Maria, Chile.

The poster is titled “Reducing the Network Load of Triple Pattern Fragments by Supporting Bind Joins.” You may want to read the poster paper, and there is also a Web page for this work. Additionally, a full research paper about this work (title: “Bindings-Restricted Triple Pattern Fragments“) will be published in the proceedings of the ODBASE 2016 conference; an extended pre-print of this paper is already available.

LiU Semantic Web research at ISWC 2016

ISWC2016 LogoNext week a couple of use will travel to Kobe, Japan, to present our work in the 15th edition of the annual International Semantic Web Conference (ISWC 2016). In particular, we will present the following two research papers:

  • “User Validation in Ontology Alignment” by Zlatan Dragisic, Valentina Ivanova, Patrick Lambrix, Daniel Faria, Ernesto Jimenez-Ruiz, and Catia Pesquita (download a pre-print of the paper), and
  • “Walking without a Map: Ranking-Based Traversal for Querying Linked Data” by Olaf Hartig and M. Tamer Özsu (pre-print, and extended version).

Furthermore, Valentina Ivanova will present her PhD project in the doctoral consortium of the conference (title of Valentina’s DC paper: “Applications of Large Displays: Advancing User Support in Large Scale Ontology Alignment“), and we have two posters in the poster session, namely “Representing RDF Stream Processing Queries in RSP-SPIN” by Robin Keskisärkkä (poster paper) and “Reducing the Network Load of Triple Pattern Fragments by Supporting Bind Joins” by Olaf Hartig and Carlos Aranda-Buil (poster paper).

In addition to these contributions to the main conference, some of us are co-organizers of research workshops and challenges co-located with the conference, that is:

  • The 7th Int. Workshop on Consuming Linked Data (COLD 2016) is co-organized by Olaf Hartig,
  • The 2nd Int. Workshop on Visualization and Interaction for Ontologies and Linked Data (VOILA 2016) is co-organized by Valentina Ivanova and Patrick Lambrix, and
  • The 7th Workshop on Ontology and Semantic Web Patterns (WOP 2016) is co-organized by Karl Hammar.
  • Zlatan Dragisic, Valentina Ivanova, Huanyu Li and Patrick Lambrix organized the Anatomy track and co-organized the Interactive track of the Ontology Alignment Evaluation Initiative (OAEI 2016). The results are reported at the Ontology Matching Workshop (OM 2016).

Moreover, in the VOILA workshop, our Patrick Lambrix, Zlatan Dragisic, and Valentina Ivanova, together with Craig Anslow, have a paper titled “Visualization for Ontology Evolution” (read the paper); Karl Hammar is co-author of two papers in the WOP workshop, titled “Template-Based Content ODP Instantiation” (paper) and “How to Document Ontology Design Patterns” (paper). Last but not least, Robin Keskisärkkä has a paper about “Query Templates for RDF Stream Processing” in the Stream Reasoning Workshop (SR 2016).

We are looking forward to having a good time at ISWC in Kobe. If you happen to be there as well and want to talk to any of us, don’t be shy, just approach us.
