Towards Question Answering on Statistical Linked Data

As an increasing amount of statistical data is published as linked data, intuitive ways of satisfying information needs and getting new insights out of the data become more and more important.

Question answering systems provide such an intuitive interface by translating natural language queries into SPARQL, which is the native query language of RDF knowledge bases.


Statistical data, however, is structurally very different from other data and cannot be queried using existing approaches.

We analyze the particularities of statistical data represented in the RDF Data Cube Vocabulary in relation to question answering and sketch a new question answering algorithm on statistical data.

In order to estimate typical user questions, a statistical question corpus is compiled and its elements are categorized.

Open registry of automotive terminologies

On 14 March 2000 ITA was founded with the goal of improving the flow of information between car manufacturers and suppliers on the one and the ICT companies on the other hand. The current focus is on the support along the entire automotive value chain.


Today, more than 50 well-known service providers are organized with different core competencies in the ITA. They know the business processes in the automotive industry in detail and successfully support national and international operations. The Automotive Industry will benefit in addition to the industry-specific expertise and experience in the local markets of excellent IT skills and innovations that enable advanced and efficient processes.

Based on this background ITA has developed vertical competency working groups who all have come up with one single common requirement: The creation of a shared data vocabulary for their industry with the goal of increasing the free flow of information between heterogenous networks of systems and industry partners.


With open. ITA is now establishing a central repository which is designed to foster the creation of open vocabulary projects within the automotive industry.


Already multiple different projects have been incubated including:

  • SCOR – Supply Chain Benchmark Vocabulary
  • E12 – Supply Chain Master Data Vocabulary

In many ways ITA will organize itself along the lines of the Eclipse Foundation, which has a long standing track record in collaborative creation of IP and providing intellectual property to industry in a way which is well aligned with the requirements of those entities creating and consuming the content. works under the motto: “collaborate on standards, compete on implementation” and thus here again follows in the footsteps of the Eclipse Foundation, who has made software creation with Java tools so much more effective and efficient and who has successfully standardized its industry with more than 80% of global java developers using Eclipse base development tools.

Efficient Search and Browsing of CSV Datasets

The paper presents an application developed within the FP7 LOD2 project that supports effcient search and browsing of CSV files. The application indexes CSV files using DBpedia categories and sophisticated strategies for identification of the best descriptors. The paper introduces the application as well as presents its usage scenario. To the best of our knowledge no similar solution exists.

Text Insights: Natural Language Analytics for Understanding Social Media Engagement

We present Text Insights, an application for understanding factors of user engagement in Facebook pages. Providing analytics based on natural language processing, Text Insights is complementary to existing tools offering mainly numerical indicators of user engagement. Our system extracts keyphrases from page content in a linguistically motivated manner. Keyphrases are weighted according to their relevance as approximations of the most important topics in the community. We demonstrate that the system provides valuable insights for page owners interested in trend discovery, content evaluation and content planning.
