June 3, 2014 - 3:20 pm by Ricardo Usbeck - No comments »


After a week full of exciting presentations, demos, posters and especially keynotes AKSW members are back from the 11th Extended Semantic Web Conference 2014 (ESWC).

Furthermore, we bring happy news with us. AKSW members won four prizes this year! In detail these are:

Meet us at!

All the best,

In the recent years the LOD2 stack established a collection of applications developed in the context of the LOD2 project, presented as an unified environment. These applications are referred to as components although they can also be installed independently. However, having all these components in a single environment eases the access from one application to the other and improves the UI experience.

As LOD2 stack is now available in it’s second version, questions of usability and end users experience came more in the focus of the ungoing development. So the LOD2 consortium set up  a survey asking users of the LOD2 stack (or the online Demonstrator) for feedback, regarding their experiences with the LOD2stack and the separate components. The outcome of this, is to fine tune development and improve the user experience in each phase of the Linked Data life cycle.

The survey is open from April 15 to June 30 and will only demand 15 minutes of your time.

The 11th edition of the International Semantic Web Conference (ISWC) took place in Boston this year and AKSW was very active with 5 of our researchers participating in the conference. ISWC is one of the key conferences for presenting the latest advancement in Semantic Web research. We were active in the following activities:

Workshop Keynote:

  1. “Managing the Life-Cycle of Large Scale Web Datasets” presented by Jens Lehmann at the Joint Workshop for Evolution and Dynamics; presentation

Workshop Presentations:

  1. Extending the WebID Protocol with Access Delegation” (Sebastian Tramp, Henry Story, Andrei Sambra, Philipp Frischmuth, Michael Martin and Sören Auer) presented by Philipp Frischmuth; paper
  2. “Query Segmentation and Resource Disambiguation Leveraging Background Knowledge” (Saeedeh Shekarpour, Axel-Cyrille Ngonga Ngomo and Sören Auer) – presented by Axel-Cyrille Ngonga Ngomo
  3. “Learning conformation rules for linked data integration” (Axel-Cyrille Ngonga Ngomo) – presented by Axel-Cyrille Ngonga Ngomo

Conference Articles:

  1. “DeFacto – Deep Fact Validation” (Jens Lehmann, Daniel Gerber,Mohamed Morsey, Axel-Cyrille Ngonga Ngomo) – presented by Daniel Gerber; project page; paper
  2. “DEQA: Deep Web Extraction for Question Answering” (Jens Lehmann, Tim Furche,Giovanni Grasso, Axel-Cyrille Ngonga Ngomo, Christian Schallhart, Andrew Sellers, Christina Unger, Lorenz Bühmann, Daniel Gerber, Konrad Höffner) – presented by Jens Lehmann; project page; paper
  3. “Managing the life-cycle of Linked Data with the LOD2 Stack” (Sören Auer, Lorenz Bühmann, Jens Lehmann, Michael Hausenblas, Sebastian Tramp, Bert van Nuffelen, Pablo Mendes, Christian Dirschl, Robert Isele, Hugh Williams) – presented by Jens Lehmann; LOD2 website; paper
  4. “RDFS Reasoning on Massively Parallel Hardware” (Norman Heino, Jeff Z. Pan) — presented by Norman Heino
  5. Link Discovery with Guaranteed Reduction Ratio in Affine Spaces with Minkowski Measures.” (Axel-Cyrille Ngonga Ngomo) — presented by Axel-Cyrille Ngonga Ngomo


  1. Semantic Web Journal Editorial Board Meeting
  2. DBpedia Meeting
  3. MIT Campus Tour

AKSW at TU Dresden PLT

June 17, 2011 - 3:34 pm by Jens Lehmann - One comment »

On June 8, I (Jens) visited the process control engineering research group (PLT) of Leon Urbas at the Dresden University of Technology. We first met on the Leipziger Semantic Web Day where Leon Urbas presented interactive Linked Data applications and decided to have a longer meeting later on. I first gave a talk on the Linked Data Lifecycle (slides as PDF), which is a central element of the vision behind the LOD2 project – a cycle of mutual refinement which can help to overcome some of the problems in using Linked Data. It extends on an earlier vision description by Sören and me.

After the initial presentation, we exchanged ideas for collaboration between our groups. The PLT group has a very strong record in large scale practical applications, mobile devices and usability testing. Since their background is automation engineering, they view semantic technologies as a way to connect large networks of knowledge in a flexible manner. They were particularly interested in some of our research and software tools like LIMES, SAIM and OntoWiki. I enjoyed staying at the group and I am looking forward to further meetings.

May 4-5: Leipziger Semantic Web Tag 2011 and Local Media Conferenz

April 16, 2011 - 5:39 pm by Sören Auer - No comments »

Like in the past two years, we again organize a Leipzig Semantic Web Day on May 5th at the marvelous Mediencampus Villa Ida. This year’s theme is “Linked Data  for the Masses”, particularly focusing on its use in enterprises. This event will not only give you the opportunity to discuss current developments around semantic web technologies, but also to get in touch with companies from the German-speaking world. LSWT2011 will have two distinguished keynote speakers: Martin Hepp will share his vision and recent developments around the GoodRelations ecommerce vocabulary with us. The second keynoter Andreas Blumauer from the Semantic Web Company in Vienna will show us how Linked Data can facilitate clean energy.

On the pre-conference day May 4th we will have two tutorials  – an introduction to the Semantic Data Web and another one on the GoodRelations ecommerce vocabulary. Also, on May 4th SoLoMo the Local Media Conference takes place at the Mediencampus, discussing developments around Groupon, Foursquare, Qype, MyHeimat and other local-oriented media.
