CubeQA—Question Answering on Statistical Linked Data by Konrad Höffner
Abstract
Question answering systems provide intuitive access to data 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. Building upon a question corpus established in previous work, we created a benchmark for evaluating questions on statistical Linked Data in order to evaluate statistical question answering algorithms and to stimulate further research. Furthermore, we designed a question answering algorithm for statistical data, which covers a wide range of question types. To our knowledge, this is the first question answering approach for statistical RDF data and could open up a new research area.

News from the WSDM 2015 by Michael Röder
Abstract
The WSDM conference is one of the major conferences for Web Search and Data Mining. Michael Röder was attending this years WSDM conference in Shanghai and wants to present a short overview over the conference topics. After that, he wants to take a closer look at FEL – an entity linking approach for search queries peresented at the conference.
