LOD2 webinar series: LOD2 in information and publishing industry

October 25, 2012 - 12:59 pm by SandraPraetor - 5 comments »

This webinar in the course of the LOD2 webinar series will present the implications of Linked Open Data and Semantic Web Technologies on the information and publishing industry.

The publishing industry is struggling with too much information on the one hand and too less resources to bring meaning to this information on the other hand. As an industrial use case partner in LOD2, Wolters Kluwer Deutschland GmbH investigates in detail, how LOD and Semantic Web have the potential to solve this critical issue for their business. The presentation will show what parts of the LOD2 stack are used within the use case and what challenges had to be addressed in the last two years. Interesting future areas like natural language processing will also be mentioned. The topics covered are relevant for any industry that deals with a lot of data and documents, not only publishing.

If you are interested in Linked (Open) Data principles and mechanisms, LOD tools & services and concrete use cases that can be realised using LOD then join us in the LOD2 webinar series!

About the LOD2 Stack
The LOD2 stack is an integrated distribution of aligned tools which support the life-cycle of Linked Data from extraction, authoring/creation over enrichment, interlinking, fusing to visualization and maintenance. The stack comprises new and substantially extended existing tools from the LOD2 partners and third parties. The LOD2 stack is organized as a Debian package repository making the tool stack easy to install on any Debian-based system (e.g. Ubuntu). The first release of the LOD2 stack contains the following components (available as Debian packages):

  • LOD2 demonstrator, the root package (LOD2)
  • Virtuoso, RDF storage and data management platform (Openlink)
  • OntoWiki, semantic data wiki authoring tool (ULEI)
  • Silk, interlinking engine (FUB)
  • D2R, RDF wrapper for SQL databases (FUB)
  • ORE, ontology repair and enrichment toolkit (ULEI)

As online services were integrated into the LOD2 Stack: PoolParty (taxonomy manager by SWCG) and Spotlight (annotating texts w.r.t. DBpedia by FUB). The LOD2 Stack also makes use of dataset metadata repositories such as and A selection of the datasets has been packaged and are available in the LOD2 stack repository.

The LOD2 stack is an open platform for Linked Data components. We are happy to welcome new components. Detailed instructions how to integrate your component into the LOD2 Stack as Debian package are available in the HOW-TO-CONTRIBUTE. For assistance or any questions related to the LOD2-stack contact From now on we will regularly release improved and extended versions of the LOD2 Stack. Major releases are expected for Fall 2012 and 2013.

Whats next – the LOD2 webinar series

The LOD2 webinar series offers several (one per month) free webinars about Linked Open Data tools and services around the LOD2 project, the LOD2 Stack and the Linked Open Data Life Cycle, also in the form of 3rd party tools.

About LOD2 – Creating Knowledge out of Interlinked Data

LOD2 is a large-scale integrating project co-funded by the European Commission within the FP7 Information and Communication Technologies Work Programme (Grant Agreement No. 257943). Commencing in September 2010, this 4-year project comprises leading Linked Open Data technology researchers, companies, and service providers (15 partners) from across 11 European countries (and 1 associated partner from KOREA) and is coordinated by the AKSW research group at the University of Leipzig, Germany.

LOD2 will integrate and syndicate linked data with large-scale, existing applications and showcase the benefits in the three application scenarios of media and publishing, corporate data intranets and eGovernment. The resulting tools, methods and data sets have the potential to change the Web as we know it today.

The Big Clean

October 16, 2012 - 1:55 pm by SandraPraetor - One comment »

The Big Clean is a free, 1-day conference that addresses the challenges associated with reuse of public sector data. The event rises to the occasion of teaching the members of public how to recycle public data and reuse it in the pursuit of their own goals, ranging from the use of data to power applications, drive societal changes and provide grounds for a data-driven journalism. The Big Clean is focused on three principal topics:

  • Screen-scraping: the skill of distilling data out of web pages and other poorly structured sources
  • Data refining: the techniques of transforming raw data into usable data
  • Data-driven journalism: the craft of telling stories with data.

The event is jointly organized by the National Technical Library and members of the LOD2 project.

Date and time: Saturday 3rd November, 2012, from 9 AM to 5 PM (GMT+1)
