LOD2 Work Packages

WP1 – Requirements, Design and LOD2 Stack Prototype

Objectives of this work package are: (1) to develop use case specifications and to collect user requirements by consulting the communities of practice relevant for the LOD2 use cases and additional prospective application scenarios, (2) to identify technical constraints as well as standards, (3)…

WP2 – Storing and Querying Very Large Knowledge bases

This work package implements the LOD2 knowledge store component needed for managing the Web of Linked Data as a vast database. The starting point is OpenLink Virtuoso and MonetDB on the database side and Sindice on the information retrieval side. The present data volumes handled are around 10 bi…

WP3 – Knowledge Base Creation, Enrichment and Repair

WP3 contains tasks focused on the transformation of legacy data to RDF and Linked Data and furthermore on the improvement of existing or extracted data especially with respect to schema enrichment and ontology repair. It is complementary to WP4, which is concerned with interlinking several knowl…

WP4 – Reuse, Interlinking and Knowledge Fusion

While WP3 is concerned with making legacy data available via URLs – a prerequisite – and enrichment of knowledge bases, this WP addresses automatic and semi-automatic link creation with minimal human interaction, evolvement of knowledge bases under the aspect of linkage and schema ma…

WP5 – Adaptive Linked Data Visualization, Browsing and Authoring

The objectives of WP5 are to develop new browsing, visualization and authoring interfaces for LOD, which support a wide range of devices (from mobile phones to desktop PCs), which integrate heterogeneous information from various sources and support the evolution of both instance data as well as …

WP6 – Interfaces, Component Integration & LOD2 Stack

This work package will continue the prototyping activity under WP1/Task 1.4 by fully integrating the individual components developed in WP2-5 into a ready-to-use LOD2 Stack and associated APIs. The primary goal of the LOD2 Stack integration is to enable communities of practice to rapidly create …

WP7 – Use Case 1: LOD2 for Media and Publishing

Enabling large-scale interoperability based on Linked Data is a necessary precondition in the media industry to profit from the benefits of distributed information sources on the Semantic Web. Hence, the media use case aims to improve access to high-quality, machine-readable data sets generated …

WP8 – Use Case 2: LOD2 for Enterprise Data Web

This use case will be driven by Exalead, one of the leading enterprise search providers worldwide. We will deploy the LOD2 platform in a real corporate environment with high semantic information integration requirements and needs. Based on the authoring tools and semantic GUIs developed for the …

WP9 – Use Case 3: LOD2 for Citizen – PublicData.eu

The purpose of this PublicData.eu use case is to increase public access to high-value, machine-readable data sets generated by the European, national as well as regional governments and public administrations. Although this effort will be similar to developments in other parts of the world, for …

WP9a – LOD2 for a Distributed Marketplace for Public Sector Contracts

The objective of this use case is to explore and demonstrate the application of linked data principles for procuring contracts in the public sector. As can be seen by the “Use of eProcurement services” indicator of the Digital agenda there is a large gap between advanced countries (e.g. Irel…

WP10 – Training, Dissemination, Community Building, Fertilization

The general aim of this work package is to establish a worldwide focal point for academic and industry parties interested in contributing to or taking advantage of the novel Linked Data methodologies and components, which will emerge in the project.

WP11 – Standardization, Exploitation

Realizing the vision of LOD2 together with the ones of the three use cases will have significant socio-economic impact. Standardization of such an architecture and exploitation of knowledge and technical results (and related IPR) is covered in this work package.

WP12 – Project Management

The project management will entail strategic, project-wide as well as day-to-day central management and coordination activities. The several different management boards which will be established in the consortium will be responsible for decisions and activities of different scope and level accor…


Testimonials

Dr. Mateja Verlič (Zemanta d.o.o., R&D)

We read a lot about people doing important things, however this time we – LOD2 partners – are the ones changing the history of Web by revolutionizing information use and reuse, contributing to semantic data standards and pushing the limits of almost every WWW-related aspect (sc… read

Dr. Jens Lehmann (Universität Leipzig, Research Group Leader)

The size and number of Semantic Web knowledge bases published as Linked Open Data has been growing tremendously over the past years. The LOD2 project will be a key factor for sustaining this momentum. More importantly, the quality of knowledge bases and the scalability of methods accessing… read

Jindřich Mynarz (University of Economics, Czech Republic)

Apart from being legally open, linked open data is an open technology. Due to its non-exclusive, non-proprietary, well-formalized, and standards-based nature, linked open data supports a wide spectrum of uses. It does not exclude any application from using it and thus it is open to be mixe… read

Dr. Mladen Stanojevic (Institute Mihajlo Pupin, Serbia)

The richness of any semantic model and the usability of represented data is dependent on the links between them. LOD2 is an important step in this direction that will enable an efficient exploration and processing of vast quantity of open data on the Web.

Mun Yong Yi (Korea Advanced Institute of Science and Technology (KAIST))

Data becomes more meaningful and powerful as they are linked and integrated. As I learn more about what LOD can do, I am convinced that it will not only change the future of the Internet but also the quality of human life. I am glad that I am participating in this project, which will defin… read

Orri Erling (OpenLink Software, Virtuoso Program Manager)

Value from information increasingly depends on integration. RDF is a great model for this. LOD2 will make RDF a cost competitive alternative in the database space, without compromising ad hoc flexibility and expressive power. read

Vojtech Svatek (University of Economics, Czech Republic)

As researcher in ontological engineering, I am excited to see LOD2 provide tools that make the generation of semantically structured data easy and thus widespread. I believe that ontological research is deemed to build upon the world views already expressed by means of simpl… read

Andreas Blumauer (Semantic Web Company, CEO)

15 years ago we all were excited when we published HTML for the first time and it didn't take a long time until all of us were "on the internet". Now we are starting to publish data on the web. Based on semantic web technologies professional data management will be possible in distributed … read

Kingsley Idehen (OpenLink Software, CEO)

Three years ago, OpenLink Software enthusiastically contributed the prowess of Virtuoso to the grassroots effort that lead to DBpedia and the Linked Open Data cloud that coalesced around it. Today, we are both honored and enthusiastic about Virtuoso's critical infrastructure role in this n… read

An internet of data opens up tremendous opportunities for our corporate and government customers. We intend to be on the forefront of this evolution. read

Christian Dirschl (Wolters Kluwer, Content Architect)

Linked (Open) Data will change the existing publishing paradigms! Creating high quality content for professional usage will remain an important factor in future publishing, but additional access points and new usage environments will equally define its success. read

Dr. Giovanni Tummarello (National University of Ireland, Galway, Research Unit Leader)

Semantic Markups on the Web could drive information reuse to enable scenarios and applications which we can now only dream of. The idea is extraordinarely compelling, but we know now it won't simply realize itself. The LOD2 project is now a great opportunity for inspired and coordinated re… read
