Mobile Semantic Query Distribution with Graph-Based Outsourcing of Subqueries.
William Van Woensel · 2015
While mobile computing domains have illustrated the usefulness of mobile semantic data, improvements in mobile hardware are paving the way for local semantic data access. To support this, a number of tools have been developed for storing, querying and reasoning over local semantic data. However, recent benchmarks have shown that mobile hardware still imposes limitations on efficient local data querying. Additionally, mobile scenarios pose unique challenges due to their dynamic nature; making it difficult to replicate semantic data a priori for local querying. In this paper, we propose a graphbased query distribution approach, which efficiently distributes query execution across configured remote datasets. Importantly, our approach aims to identify subqueries that can be outsourced to remote datasets, thus reducing local joining work.
