YARS2: A Federated Repository for Querying Graph Structured Data from the Web

by: Andreas Harth, Jürgen Umbrich, Aidan Hogan, and Stefan Decker

In: Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, Vol. 4825 Berlin, Heidelberg: Springer Verlag (November 2007) , p. 211--224.

Abstract

We present the architecture of an end-to-end semantic search engine that uses a graph data model to enable interactive query answering over structured and interlinked data collected from many disparate sources on the Web. In particular, we study distributed indexing methods for graph-structured data and parallel query evaluation methods on a cluster of computers. We evaluate the system on a dataset with 430 million statements collected from the Web, and provide scale-up experiments on 7 billion synthetically generated statements.
