Best-effort Linked Data Query Processing with time constraints using ADERIS-Hybrid

Steven Lynden, Isao Kojima, Akiyoshi Matono and Akihito Nakamura
Answering SPARQL queries over theWeb of Linked Data is a challenging problem. Approaches based on distributed query processing provide up-to-date results but can suffer from delayed response times, indexing-based approaches provide fast response times but results can be out-of-date and the costs of indexing the growing Web of Linked Data are potentially huge. Hybrid approaches try to offer the best of both. In this demo paper we describe a system for answering SPARQL queries within fixed time constraints by accessing SPARQL endpoints and the Web of Linked Data directly.
