Abstract / Description:Driven by the success of the Linked Open Data initiative
today's Semantic Web is best characterized as a Web of interlinked
datasets. Hand in hand with this structure new challenges to query
processing are arising. Especially queries for which more than one data
source can contribute results require advanced optimization and evaluation
approaches, the major challenge lying in the nature of distribution:
Heterogenous data sources have to be integrated into a federation to
globally appear as a single repository. On the query level, though, techniques
have to be developed to meet the requirements of efficient query
computation in the distributed setting.We present FedX, a project which
extends the Sesame Framework with a federation layer that enables ef-
ficient query processing on distributed Linked Open Data sources. We
discuss key insights to its architecture and summarize our optimization
techniques for the federated setting. The practicability of our system will
be demonstrated in various scenarios using the Information Workbench.
