An RDF Query Language based on Logic Programming

نویسنده

  • Jesús Manuel Almendros-Jiménez
چکیده

In this paper we investigate an extension of XQuery for querying (and inferring) from RDF documents. Following a graph based approach for specifying queries against RDF, XQuery is extended with construction of answers and boolean predicates for RDF entailment relationship inference. We will also study how to implement it in logic programming by using logic rules for executing RDF/XQuery queries.

A Logic Programming approach for Acess Control over RDF

The Resource Description Framework (RDF) is an interoperable data representation format suitable for interchange and integration of data, especially in Open Data contexts. However, RDF is also becoming increasingly attractive in scenarios involving sensitive data, where data protection is a major concern. At its core, RDF does not support any form of access control and current proposals for ext...

Taming Existence in RDF Querying

We introduce the recursive, rule-based RDF query language RDFLog. RDFLog extends previous RDF query languages by arbitrary quantifier alternation: blank nodes may occur in the scope of all, some, or none of the universal variables of a rule. In addition RDFLog is aware of important RDF features such as the distinction between blank nodes, literals and URIs or the RDFS vocabulary. The semantics ...

RDFLog: It’s like Datalog for RDF

RDF data is set apart from relational or XML data by its support of rich existential information in the form of blank nodes. Where in SQL databases null values are scoped over a single tuple, blank nodes in RDF can span over any number of statements and thus can be seen as existentially quantified variables. Blank node querying is considered in most RDF query languages, but blank node construct...

A new approach based on NμSMV Model to query semantic graph

The language most frequently used to represent the semantic graphs is the RDF (W3C standard for meta-modeling). The construction of semantic graphs is a source of numerous errors of interpretation. Processing of large semantic graphs can be a limit to use semantics in modern information systems. The work presented in this paper is part of a new research at the border between two areas: the sema...
