  • Ik ben bert Van Nuffelen from the LOD2 partner TenForce, I am leading WP6, the workpackage that is in charge of the integration effort and the construction of the LOD2 stack. today I will tour around the first version of the LOD2 stack. We first introduce you to the base concepts of the LOD2 stack And then demonstrate the current version in the context of 2 small usecases, One based on the WP7 and the other based on a LOD2 publink exercise. Finally we wrap up and answer your questions. At any moment you can to us via the chat window your questions. We will collect them and answer them at the end. VRAAG: hoe kunnen ze stellen, bij Lamdba intro misschien enkele technische richtlijnen meegeven.
  • The LOD2 stack is the supporting structure to bring those tools and components to the end user (you) so that the publishing process of Linked data is eased. How do we get our content (documents, pdfs, excelsheets, …) in RDF and then part of the Linked Data Web (Toon excel, word, pdf docs) -> toon (RDF doc) -> toon Linked data web From a distance these are the processes involved in the linked data publication
  • 1 Extraction: from doc to RDF 2. Storage: native storage and access, supported excellent standards: RDF, SPARQL, SKOS, OWL, 3. Authoring: management of the data, corrections, tracking changes… 4. Linking: The distinguishing part for LOD data publication. The goal is to related your data with data that is not under your control. 5. Enrichment: if linked new insights can be (semi)automatically be added 6. Quality: asses the overall quality 7. Repair: (=semi)automatic corrections Evolution: adaptations to new business models 8. Explore and browse by the end-user. Disticting is sometimes artificial and order is not strict. The LOD2 stack has industrial strength tool support for the left part. The right part is much more research oriented
  • Where setup time in 2010 was serveral days, you can do it now in half a day from scratch. When we do the next presentation in a years time, more should be possible in an easier fashion.
  • Wat do you need to install the lod2 stack
  • Like the oracle-java compiler.
  • These offer you the necessary RICHNESS The use case examples are simplified examples from Linked Data publishing experiences in LOD2 which are used to demonstrate the capabilities of the LOD2 stack components. Disclaimer. The LOD2 stack does not come with a single harmonized user interface. So in the demo some steps are made in a technical fashion
  • This work package aims at evaluating the LOD2 stack and the LOD publishing process for the media and publishing domain. The partner Wolters Kluwer Germany (WKD) is very active in the legal industry and is a global player. They have contributed a large dataset of documents. The documents are in xml format. We have extracted meta data statements about these documents in RDF format. We have created controlled vocabularies ( taxonomies) delimiting the ranges of some meta data annotations Aim: evaluation of the LOD2 stack and the LOD publishing process for the media and publishing domain
  • Tools used: RDF extractor for XML (valiant/TenForce), Storeage (virtuoso/OpenLink) and Taxonomy management (PoolParty/PoolPartyExtractor/Semantic Web Company) The idea is here to extract from the structured content (XML documents) rdf meta data (structure of the document, annotations like about which legal domain the text is, what the application area of the text is, etc.)
  • Here the idea is that new not yet annotated documents can get a first annotation based on the taxonomy constructed in PoolParty.
  • The LOD2 stack can be used by you to distribute your component is a reliable way to potential users. If you have feedback on the webinar contact our webinar responsible.

  • 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. This 4-year project comprises leading Linked Open Data technology researchers, companies, and service providers. Coming from across 12 countries the partners are coordinated by the Agile Knowledge Engineering and Semantic Web Research Group at the University of Leipzig, Germany. LOD2 will integrate and syndicate Linked Data with existing large-scale applications. The project shows the benefits in the scenarios of Media and Publishing, Corporate Data intranets and eGovernment. http://lod2.euLOD2 Webinar . 29.11.2011 . Page 2 http://lod2.eu
  • Creating Knowledge out of Interlinked Data Once per month the LOD2 webinar series offer a free webinar about tools and services along the Linked Open Data Life Cycle. Stay with us and learn more about acquisition, editing, composing, connected applications – and finally publishing Linked Open Data. http://lod2.euLOD2 Webinar . 29.11.2011 . Page 3 http://lod2.eu
