- 508 abstract "Large amounts of data reside in sources which are not web- accessible. Wrappers - small software programs that provide uniform access to data - are often used to transform legacy data sources for use on the Semantic Web.Wrappers, as well as links between data from wrapped sources and data that already exists on the Web, are typically created in an ad-hoc fashion. We propose a principled approach to integrating data-providing services with Linked Data. Linked Data Services (LIDS) can be used in various application scenarios to provide uniform access to legacy data and enable automatic interlinkage with existing data sets.".

- 509 sameAs 509.
- 509 abstract "To the best of our knowledge, existing Semantic Web (SW) search systems fail to index RDF graph structures as graphs. They either do not index graph structures and retrieve them by run-time formal queries, or index all row triples from the back-end repositories. This increases the overhead of indexing for very large RDF documents. Moreover, the graph explorations from row triples can be complicated when blank nodes, RDF collections and containers are involved. This paper provides a means to index SW data in graph structures, which potentially benefit the graph exploration and ranking in SW querying.".

- 51 sameAs 51.
- 51 abstract "Starting from the general framework for annotated RDF(S) which we have presented in previous work, we address the development of a query language - AnQL - that is inspired by SPARQL, including several features of SPARQL 1.1. As a side effect we propose formal definitions of the semantics of these features (subqueries, aggregates, assignment, solution modifiers) which could serve as a basis for the ongoing work in SPARQL 1.1. We demonstrate the value of such a framework by comparing our approach to previously proposed extensions of SPARQL and show that AnQL generalises and extends them.".

- 510 abstract "In general, ranking entities (resources) on the Semantic Web (SW) is subject to importance, relevance, and query length. Few existing SW search systems cover all of these aspects. Moreover, many existing efforts simply reuse the technologies from conventional Information Retrieval (IR), which are not designed for SW data. This paper proposes a ranking mechanism, which includes all three categories of rankings and are tailored to SW data.".
