This paper presents a thesaurus of ancient and medieval zoological knowledge, called THEZOO, constructed in the framework of the International Research Group Zoomathia. It aims at integrating heterogeneous data sources on zoology in Antiquity and Middle Ages: mainly texts, but also images, archaeological objects and archaeozoological material....

In this paper we propose an approach to manage access rights in a content management systems which relies on semantic web models and technologies. We present the AMO ontology which consists (1) in a set of classes and properties dedicated to the annotation of resources whose access should be controlled and (2) in a base of inference rules...

—In this paper we present the KGRAM abstract machine dedicated to querying knowledge graphs. It is the result of an abstraction process we performed to reach a generic solution to the problem of querying graphs in various models. We identified high level abstract primitives that constitute the expressions of the query language and the...

Dans cet article nous présentons la machine abstraite KGRAM et son langage GRAAL pour l'interrogation de graphes de connaissances. KGRAM et GRAAL sont le résultat d'un travail d'abstraction que nous avons mené afin de proposer une solution générique au problème de l'interrogation de graphes de connaissances de différents modèles. Ce faisant,...

Reusing existing web resources for e-learning is a very promising and highly promoted idea in the research field of web-based education, especially for intelligent or adaptive systems where the cost of authoring is tremendous. However methodologies and tools are still lacking and feasibility at reasonable cost is a pending issue. In this paper...

In this paper we first present the STTL (SPARQL Template TransformationLanguage) language for the transformation of RDF graphs, designed as an exten-sion of SPARQL. Then we present a STTL-based platform for the design of Webbrowsers for the Linked Data. This platform is a SPARQL endpoint augmentedwith an STTL engine and services to run STTL...

XSLT is a language for transforming XML documents into other XML documents. Despite its 16 years long life, the RDF Semantic Web language still waits its transformation language. Some propositions have been done, relying on and extending XSLT, but none of them became widely used. In this paper, we present a radically new transformation language...

The general research question addressed in this paper is: "How to transform RDF into other languages". This is of prime interest to present data selected and extracted from the Web of data in a format suitable for the user (e.g., HTML or CSV). Moreover, RDF can be viewed as a meta-model to represent on the Web of data other languages and...

The basic principle of the Semantic Web carried by the RDF data model is that a collection of RDF statements coex-ist all together and are universally true. However some case study imply contextual relevancy and truth. The SPARQL query language is provided with patterns enabling to choose the RDF dataset against which a query is executed. This...

RDF est un langage de représentation de connaissances basé sur des graphes étiquetés, conçu par le W3C pour le Web sémantique et le Web des données. En tant que langage d'échange pivot, il peut être utilisé pour représenter des arbres de syntaxe abstraite (AST) de langages. Par exemple le langage OWL a plusieurs syntaxes dont une syntaxe...

The SPARQL query language for RDF is the standard recommended by the W3C to query the Semantic Web. It enables to query and search RDF data by using query graph patterns and filters restricting the solutions produced by graph pattern matching according to the constraints they express. Constraints are either expressions defined according to the...
