An Infrastructure for Distributed Query Answering over Networked Ontologies
A poster presentation written by Yimin Wang, Peter Haase, Raphael Volz and Jia Yu. It was presented at the ESWC2007. It is about Distributed System, Networked Ontology, Distributed Query Answering and Performance
Recently many semantic information systems go beyond individual systems towards networked systems. An important architecture is the distributed scenario, where user queries get passed between nodes to compute the answers to queries in a distributed fashion. The paper addresses the complex setup where ontologies used in such are heterogeneous and can be connected with each other to form networked ontologies. We address the problem to answer queries stated towards such networked ontologies in a distributed manner. We present a novel algorithm computing the answer to such queries that takes into account whether the ontologies in the networked system are self-contained or coupled with each other. Different query distribution strategies are used for either case. The performance of the algorithm is evaluated and proves to be favorable to our prior work.
