    Choosing Between Graph Databases and RDF Engines for Consuming and Mining Linked Data

    Graphs naturally represent linked data and implementations of graph-based tasks are required not only for data consumption, but also for mining patterns among links. Despite efficient graph-based algorithms and engines have been implemented, there is no clear understanding of how these solutions may behave on Linked Data. The authors evaluate...

    SemLAV: Local-as-View Mediation for SPARQL Queries

    Local-as-view mediators allow to query semantic heterogeneous data sources such as linked data endpoints, open data servers or any available web service. Nevertheless, the problem of rewriting conjunctive queries on LAV mediators is intractable in general, and the number of rewritings can be exponential on the size of the query....

    Benchmarking Federated SPARQL Query Engines: Are Existing Testbeds Enough?

    Testbeds proposed so far to evaluate, compare, and eventually improve SPARQL query federation systems have still some limitations. Some variables and configurations that may have an impact on the behavior of these systems (e.g., network latency, data partitioning and query properties) are not sufficiently defined; this affects the results and...

    Trusted SMS Communication on Mobile Devices

    The exponential growth of the Short Message Service (SMS) use has transformed this service in a widespread tool for social and commerce messaging. However, security concerns have been raised as applications become more critical and complex. Thus, this paper introduces an SMS security framework, which allows programmers and users to...
