Abstract
Due to advancements in mobile technology and connectivity, mobile devices have become fully-fledged web clients. At the same time, more and more Semantic Web data is becoming available, to a point where it becomes usable for various mobile application scenarios. However, most applications are limited to using pre-defined query endpoints in order to access Semantic Web data, which leaves a huge part of the Semantic Web, consisting of online RDF files and semantically annotated websites, inaccessible. In this paper, we present a mobile query service for the efficient and transparent querying of large amounts of small online RDF sources. In order to achieve this, the query service relies on two key components: 1/ a lightweight semantics-based indexing scheme, to identify sources relevant to posed queries, and 2/ a caching mechanism that locally stores frequently-used data.
