We present two generic and highly re-usable resources for RDF knowledge bases: a component for PageRank-based ranking and a component for entity summarization.  ...  In addition, this work outlines the application of the components for PageRank-based RDF ranking and entity summarization in the question answering project WDAqua.  ...  Questions using Web Data (WDAqua).  ...

Thanks to the development of the Semantic Web, a lot of new structured data has become available on the Web in the form of knowledge bases (KBs).  ...  We first introduce a new approach for translating natural language questions to SPARQL queries.  ...  We integrated our system as a Qanary QA component called WDAqua-core1. We choose Qanary for two reasons.  ...
