Translations between RDF(S) and Conceptual Graphs [chapter]

Jean-François Baget, Madalina Croitoru, Alain Gutierrez, Michel Leclère, Marie-Laure Mugnier
2010 Lecture Notes in Computer Science  
Though similarities between the Semantic Web language RDF(S) and languages of the Conceptual Graphs family have often been pointed out, the differences between these formalisms have been a source of difficulties  ...  while trying to translate objets of a language into the other.  ...  More specifically, we will focus on transformations between Conceptual Graphs (CGs) [10, 4] and the RDF(S) language [8] , the standard for Semantic Web annotations.  ...

A Conceptual Graph and RDF(S) Approach for Representing and Querying Document Content [chapter]

R. Carolina Medina Ramírez, Olivier Corby, Rose Dieng-Kuntz
2002 Lecture Notes in Computer Science  
This article describes a first synthesis of a Conceptual Graph and RDF(S) approach for representing and querying document contents.  ...  The motivation of this paper is to give a first synthesis of the translation process from the pivot language to RDF(S) and CG, to underline the main problems encountered during this translation.  ...  Translation Process: Pivot Language-RDF(S)-CG In this section, we detail the process of translating ontologies and annotations from pivot language to RDF(S) and conceptual graphs.  ...

Cognitive agents and machine learning by example: Representation with conceptual graphs

Alexandros Gkiokas, Alexandra I. Cristea
2018 Computational intelligence  
It has been shown that MRL and RDF can be translated to CG, and as such it is plausible that even without a graph being the representation, a spatialtemporal sequence could Markovianly describe another  ...  In addition to creating nodes, an action can also be the decision to create edges between concepts and relations, and thus creating a connected conceptual graph. [ Figure 4 about here.]  ...

Extending RDF(S) with Contextual and Definitional Knowledge

Alexandre Delteil, Catherine Faron-Zucker
2001 International Joint Conference on Artificial Intelligence  
This extension is based on the similarities between the RDF and CG models: a context is just the translation of a conceptual graph.  ...  Section 3 is dedicated to the comparison of RDF(S) and the Conceptual Graphs model.  ...

Efficiently Querying RDF(S) Ontologies with Answer Set Programming

G. Ianni, A. Martello, C. Panetta, G. Terracina
2008 Journal of Logic and Computation  
Results reported in the paper show that our proposed framework is promising for the improvement of both scalability and expressiveness of available RDF(S) storage and query systems.  ...  This work is a first step toward this setting: it first shows that RDF(S) ontologies can be expressed, without loss of semantics, into Answer Set Programming (ASP).  ...  In order to encode in ASP the problem of deciding RDFS entailment between two graphs G 1 and G 2 , we adopt two translations T 1 and T 2 , and an ASP EX program D, which simulates RDFS entailment rules  ...

OWL-S for Describing Artifacts

Rossella Rubino, Ambra Molesini, Enrico Denti
2006 European Workshop on Multi-Agent Systems  
In particular, we investigate how to represent the artifact features by means of OWL-S, provide an example, and discuss some preliminary results in terms of advantages and limitations of this approach.  ...  In order to enable agents to autonomously discover the available services, select the proper artifact(s), and use the services they need, it is necessary to describe the services offered by artifacts in  ...  Artifact Representation The mapping between the artifact features and OWL-S could be represented through an RDF Graph as depicted in Figure 2 .  ...

Searching and Establishment of S-P-O Relationships for Linked RDF Graphs : An Adaptive Approach [article]

2013 arXiv   pre-print
For analyzing inter relationship between two RDF Graphs, RDF- Schema (RDFS) should also be taken care of.  ...  In the present paper, an adaptive combination rule based framework has been proposed for establishment of S P O relationship and RDF Graph searching is reported.  ...  between RDF graphs within the scope of S 1 and S 2 .  ...

A Datatype Extension for Simple Conceptual Graphs and Conceptual Graphs Rules [chapter]

Jean-François Baget
Lecture Notes in Computer Science  
We propose in this paper an extension of Conceptual Graphs that allows to use datatypes (strings, numbers, ...) for typing concept nodes.  ...  Though the model-theoretic semantics of these datatypes is inspired by the work done for RDF/RDFS, keeping sound and complete projection-based algorithms for deduction has led to strong syntactic restrictions  ...  With simple conceptual graphs, there is no distinction between full and partial semantics (since there is no string). Every graph is satisfiable, and the only valid graph is the empty graph.  ...

The CG Formalism as an Ontolingua for Web-Oriented Representation Languages [chapter]

Olivier Gerbé, Guy W. Mineau
2002 Lecture Notes in Computer Science  
Though there may be many knowledge representation formalisms suited for that task, we advocate the use of the conceptual graph formalism.  ...  It is expected that many one-to-one mappings between pairs of document representation formalisms will eventually arise.  ...  Tim Berners-Lee compared RDF and conceptual graphs and concluded that Conceptual Graphs are easily integrated with the Semantic Web [2] .  ...

Converting Alzheimer s disease map into a heavyweight ontology: a formal network to integrate data [article]

Vincent Henry, Ivan Moszer, Olivier Dameron, Marie-Claude Potier, Martin Hofmann-Apitius, Olivier Colliot
2018 arXiv   pre-print
Alzheimer s disease (AD) pathophysiology is still imperfectly understood and current paradigms have not led to curative outcome.  ...  AlzPathway is a disease map that gives a detailed and broad account of AD pathophysiology. However, AlzPathway lacks formalism, which can lead to ambiguity and misinterpretation.  ...  The research leading to these results has received funding from the program "Investissements d'avenir" ANR-10-IAIHU-06 (Agence Nationale de la Recherche-10-IA Institut Hospitalo-Universitaire-6) and from  ...

A Conceptual Graph Model for W3C Resource Description Framework [chapter]

Olivier Corby, Rose Dieng, Cédric Hébert
2000 Lecture Notes in Computer Science  
Our approach is to exploit a standard language (RDF, recommended by W3C) for expressing such metadata and to interpret these metadata in conceptual graphs (CG) in order to exploit querying and inferencing  ...  The paper presents our mapping of RDF into CG and its interest in the context of the semantic Web.  ...  Acknowledgement We thank Ahmed Amerkad who implemented the CG to RDF translator, Peter Eklund, Philippe Martin and Denis Kuntz for proofreading the paper, the remaining errors being ours.  ...
