The closing ceremony of ISWC2011 in Bonn is just over and we are excited to have won the best research paper award with our paper:

Mohamed Morsey, Jens Lehmann, Sören Auer, Axel Cyrille Ngonga Ngomo: DBpedia SPARQL Benchmark – Performance Assessment with Real Queries on Real Data. To appear in Proceedings of 10th International Semantic Web Conference (ISWC2011), Oct 23-27, 2011, Bonn, Germany. [BIB]

In the paper we describe on the example of DBpedia how domain-specific SPARQL benchmarks can be generated and used for assessing the performance of triples stores.

Its a great  success for Mohamed Morsey, who did most of the implementation work and is only in the second year of his PhD studies at AKSW.

Hello world,

We are happy to announce that LIMES has been extended with an interface that will make linking easier than ever before. The COLANUT (Complex Linking in a NUTshell) interface implements time-efficient schema matching algorithms that allow LIMES to discover and suggest initial class and properties matchings for linking. The whole is embedded in an easy-to-use GUI that allows you to create link specifications easily and download them as XML files or simply to run them online. Check COLANUT out at http://limes.aksw.org/colanut. A technical description can be found here.

And before I forget, two papers centered around linking with LIMES were accepted at OM2011, the ontology matching workshop at ISWC. Come around and get all details on the exciting development around LIMES and Link Discovery in general.

Link on,
Axel

Together with the FU Berlin members of the DBpedia team Sebastian, Jens and Sören won the Journal of Web Semantics Most Cited Article 2006-2010 Award for the paper: DBpedia – A Crystallization Point for the Web of Data. The paper appeared in the special issue “The Web of Data” in Volume 7, Issue 3 of the Journal of Web Semantics (JWS) Elsevier in 2009. Since its publishing, DBpedia became a hub on the Web of Data and a crucial resource for many research approaches. From that perspective, its not surprising that the paper gets cited a lot, although much has changed meanwhile in DBpedia: there is now the DBpedia ontology, we have a collaborative mapping system in place for aligning the DBpedia data with this ontology. There are a number of internationalization efforts and DBpedia Live, which provides real-time updates is slowly maturing.

Members of AKSW are actively participating in some key (Semantic) Web conferences this spring.

AKSW was already involved in the organization of 8th Extended Semantic Web Conference 2011 with Jens being one of the PC Chairs of the Linked Data track and a number of other AKSW researchers serving as members of the PC of various tracks, workshops and side events. Now also three AKSW submissions were accepted for the main conference programm (having a 23% acceptance rate) at ESWC:

• AutoSPARQL: Let Users Query Your Knowledge Base by Jens Lehmann and Lorenz Bühmann
• OntoWiki Mobile – Knowledge Management in your Pocket by Timofey Ermilov, Norman Heino, Sebastian Tramp, Sören Auer
• Weaving a Distributed, Semantic Social Network for Mobile Users by Sebastian Tramp, Philipp Frischmuth, Natanael Arndt, and Sören Auer

For 11th International Conference on Web Engineering (ICWE 2011), Sören serves as chair of the programme committee and Axel is one of the Demo & Poster Chairs.

Sören is also giving a key-note on “Creating Knowledge Out of Interlinked Data” at the International Conference on Web Intelligence, Mining and Semantics (WIMS’11). WIMS takes place from May 25th-27th in Sogndal, Norway.

The AKSW research group is represented in the main ISWC conference programme this year with four papers. International Semantic Web Conference (ISWC) is the major international forum where the latest research results and technical innovations on all aspects of the Semantic Web are presented. Acceptance rates for the main conference programme were this year 20% for the research track and 26% for the In-Use track. AKSW’s presentations at ISWC in Shanghai include:

• Christoph Rieß, Norman Heino, Sebastian Tramp, Sören Auer: EvoPat – Pattern-Based Evolution and Refactoring of RDF Knowledge Bases.
• Jens Lehmann and Lorenz Bühmann: ORE – A Tool for Repairing and Enriching Knowledge Bases.
• Sören Auer, Matthias Weidl, Jens Lehmann, Amrapali J. Zaveri, Key-Sun Choi: I18n of Semantic Web Applications.
• Thomas Riechert, Ulf Morgenstern, Sören Auer, Sebastian Tramp, Michael Martin: Knowledge Engineering for Historians on the Example of the Catalogus Professorum Lipsiensis.

The paper titled Knowledge Engineering for Historians on the Example of the Catalogus Professorum Lipsiensis was awarded the best In-Use track paper award.
