Ontology-Based Modelling of Ocean Satellite Images
In this paper we will define an ontology about the semantic content of ocean satellite images in which we are able to represent types of ocean structures, spatial and morphological concepts, and knowledge about m...

Querying and Reasoning with RDF(S)/OWL in XQuery
In this paper we investigate how to use the XQuery language for querying and reasoning with RDF(S)/OWL-style ontologies. Our proposal allows the handling of RDF(S)/OWL triples by means of a XQuery library for ...

XPath for Querying GML-Based Representation of Urban Maps
Geography Markup Language (GML) has been established as the standard language for the transport, storage and modelling of geographic information. In this paper we study how to adapt the XPath que...

A Flexible XPath-Based Query Language Implemented with Fuzzy Logic Programming
In this paper we present an extension of the XPath query language for the handling of flexible queries. In order to provide ranked answers, our approach proposes fuzzy variants of and, or and avg operators for XP...

OWL RL in Logic Programming: Querying, Reasoning and Inconsistency Explanations
In this paper we describe a logic programming based implementation of the OWL 2 RL fragment. We show how goals are used for querying, forward reasoning permits to infer new knowledge, and ontology inconsistenc...

Fuzzy XPath for the Automatic Search of Fuzzy Formulae Models
In this paper we deal with propositional fuzzy formulae containing several propositional symbols linked with connectives defined in a lattice of truth degrees more complex than Bool. Instead of focusing on satisf...

Declarative Debugging of XML Queries
In this paper we present the elements of an algorithmic debugger for XQuery. Given a XQuery program/query, a debugging tree is built in which the root is the query and the answer, and non-root nodes contain th...
