More than 20 European Union Datasets Converted to RDF by LATC Project

July 9, 2012 - 2:13 pm by Jens Lehmann - 2 comments »

Over the past two years, the LATC project (Linked Open Data Around-The-Clock) has worked on converting more than 20 EU datasets to RDF, make them available as Linked Data and SPARQL, and link them to other datasets. The datasets have gone through internal quality assurance against a publication checklist. LATC supports the EU Open Data Portal initiative and aims to bootstrap the creation of an EU dataset cloud by this effort. The datasets include several business, legal and statistical datasets such as CORDIS, the European Commission Financial Transparency System, EUR-Lex, EuroStat and many more. A full list of all converted datasets, SPARQL endpoints and documentation can be found at:

Can we create better links by playing games?

June 20, 2012 - 7:51 pm by Jens Lehmann - No comments »

Most of you will agree that links are an important element of the Web of Data. There exist a number of tools, such as LIMES or SILK, which are able to create a high number of such links by using heuristics. The manual validation of verification of such links can be very time-consuming, so we try to find out whether game based approaches can be used to make that task much more interesting. We developed the VeriLinks game prototype and ask for your help to judge how well the the validation works by playing the game and answering a few questions in a survey:

Game: http://verilinks.aksw.org
Project Page: http://aksw.org/projects/VeriLinks
Survey: http://surveys.aksw.org/survey/verilinks

The survey itself takes only 5 minutes to complete. In addition to having the chance to play a game at work , there are also great prizes to win. 10 randomly selected participants will receive Amazon vouchers:

1st prize: 200 Euro
2nd prize: 100 Euro
3rd prize: 50 Euro
4th – 10th prize: 25 Euro

If you want to win a prize, please participate in the survey until this Friday, June 22, 23:59 CET.

Kind regards,

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.

We thank the following LSWT sponsors for their support:




AKSW takes part in EU-funded LATC project

November 30, 2010 - 3:44 pm by Jens Lehmann - One comment »

The AKSW group is member of the recently started LATC (Linked Open Data Around-The-Clock) project funded by the European Union. LATC aims to improve quality and quantity of Linked Data on the Web, e.g. by developing a 24/7 interlinking engine. Read more in the official LATC Press Release:

In this, the Petabyte Age, technologists have a growing obsession with data—big data. But data isn’t just the province of trained specialists anymore. Data is changing the way scientists research, the way that journalists investigate, the way government officials report their progress and the way citizens participate in their own governance. The emerging Web of Linked Data is the largest source of multi-domain, real-world and real-time data that currently exists. As data integration and information quality assessment increasingly depends on the availability of large amounts of real-world data, these new technologists are going to need to find ways to connect to the Linked Open Data (LOD) cloud (http://lod-cloud.net/).

With the explosive growth of the LOD cloud, which has doubled in size every 10 months since 2007, utilizing this global data space in a real-world setup has proved challenging. The amount and quality of the links between LOD data sources remains sparse and there is no well-documented and cohesive set of tools that enables individuals and organizations to easily produce and consume Linked Open Data.

A new project aims to change this, making it easier to connect to the LOD cloud by offering support to data owners, such as government agencies, Web developers who want to build applications with Linked Data, and Small and Medium Enterprises (SMEs) that want to benefit from the lightweight data integration possibilities of Linked Data. The LOD Around-the-Clock (LATC) project is an EU co-funded project comprised of leading Linked Open Data researchers and practitioners. Co-ordinated by the Digital Enterprise Research Institute, NUI Galway (Ireland), LATC brings together a team of Linked Data researchers and practitioners from the Vrije Universiteit Amsterdam (The Netherlands), Freie Universität Berlin (Germany), Institut für Angewandte Informatik, Universität Leipzig (Germany) and Talis Ltd (United Kingdom) who will, over the next two years, support people and institutions in consuming and publishing Linked Open Data, on the Web and in the Enterprise.

In addition to the LATC core team, a large Advisory Committee with more than 35 members participates in the LATC activities: governmental organisations such as the UK Office of Public Sector Information and the European Environment Agency; researchers and practitioners such as the University of Manchester, University of Economics Prague, Vulcan Inc., CTIC Technological Center Spain, the Open Knowledge Foundation; last but not least standardisation bodies, including W3C (represented by Sir Tim Berners-Lee).
