LinkedGeoData Google Code Project Started

March 24, 2010 - 10:13 am by Jens Lehmann - No comments »

We decided to open source the code for the LinkedGeoData project and move it to Google Code:
http://code.google.com/p/linkedgeodata/

Initially, we will migrate the Triplify code, the LinkedGeoData browser, and the DBpedia mapping code into the repository. Naturally, it will take a while for the migrated code base to work as expected.

We will use the issue tracker as a central means for organising code enhancements. If you find bugs or have feature requests, please add them: http://code.google.com/p/linkedgeodata/issues/list

AKSW Publications on this Year’s Leipzig Book Fair

March 18, 2010 - 12:45 pm by ThomasRiechert - No comments »

At this year’s book fair in Leipzig (18/03 – 21/03) two books resulting from current project work of the AKSW research group [1,2] are displayed within the scope of scientific publications from the University of Leipzig. One of the editors, Thomas Riechert, will be present on 19th March from 10 to 12 o’clock at booth G201/H200 (hall 3).

ORE 0.1 Released

March 16, 2010 - 12:19 am by Jens Lehmann - No comments »

The set of tools released by the AKSW research group has a new member: ORE. ORE stands for ontology repair and enrichment. It is a tool for knowledge engineers to improve an OWL ontology through a wizard like repair process. It uses state-of-the-art methods for fixing inconsistencies and suggesting additions to an ontology, while still being efficient for small and medium sized ontologies. A screencast, which demonstrates its functionality, is available. As usual, the tool is available as open source, so you are free to download it. More information is available on the ORE wiki page. While the initial release already offers some quite powerful features, we plan to extend the tool in the mid term future with full support for knowledge bases available as Linked Data or SPARQL endpoints (as opposed to OWL/RDF files) and the detection of many common modelling errors. Thanks to Lorenz Bühmann for implementing ORE in his master thesis.

Semantic Pingback

March 10, 2010 - 8:35 pm by Sebastian Tramp - No comments »

This is an announcement of the technical report as well as three different implementations of Semantic Pingback.

Semantic Pingback tackles the quality, timeliness and coherence as well as direct end user benefits of the emerging Linked Data Web. Semantic Pingback extends the well-known Pingback method, which is a technological cornerstone of the blogosphere.

It is based on the advertising of an RPC service for propagating typed RDF links between Data Web resources. It is downwards compatible with conventional Pingback implementations, thus allowing to connect and interlink resources on the Social Web with resources on the Data Web.

We implemented the Semantic Pingback mechanism in three different scenarios:

  • A Semantic Pingback server and client plugin for OntoWiki
  • A Semantic Pingback server integrated in Triplify, thus supporting the interlinking with relational data on the Data Web.
  • A standalone Semantic Pingback server was implemented in PHP, that can be utilized with arbitrary resources that do not provide a Pingback service themselves.

If you do not want to provide a Pingback service on your own, you can use the AKSW Semantic Pingback Service which notifies you via email.
