This paper presents a computational framework for identity and is particularly focused on identifying the culprit in a crime-scene investigation. A case is conceptualized as a constellation of situations in the sense of Barwise’s situation theory. Data on a case is stored as RDF triples in a triple store. Several relevant OWL ontologies have been developed and supplemented with SWRL rules. Unce...

With the advent of Mobile and Pervasive computing, the applications and services are required to adapt dynamically according to changing environmental situations. Context aware system senses the change in computational surroundings and dynamically adapts their behaviour to environmental change without any user intervention. Using contexts such as time, location people and activity, WSNs know wh...

During the past years, the data deluge that prevails in the World Wide Web has been accompanied by a number of APIs that expose business logic. In this paper, we discuss a novel approach to enrich existing API standards definitions with business rules. Taking advantage of the REST principles, we aim at enabling the creation of generic clients that can dynamically navigate through semantically e...

We have developed a new pricing and scoring application for a large insurance company’s car insurance products. The business logic of this application is entirely expressed in an OWL ontology and SWRL rules. The ontology and rules are not merely documentation or a specification of the application, they form the business logic of the application. In other words the application is ontology-centri...

TOOL PRESENTATION: Rule languages and inference engines incorporate reasoning capabilities to Web information systems. This demonstration paper presents a tool for the development of rulebased applications for the Web based on OWL and SWRL ontologies. The tool applies a model-driven approach to an ontology representing a domain conceptualization and inference model of the problem domain. It aut...

We propose a description-logic style extension of OWL 2 with nominal schemas which can be used like“variable nominal classes”within axioms. This feature allows ontology languages to express arbitrary DL-safe rules (as expressible in SWRL or RIF) in their native syntax. We show that adding nominal schemas to OWL 2 does not increase the worst-case reasoning complexity, and we identify a novel tra...

This paper describes an hybrid method combining symbolic and numerical techniques for annotating brain Magnetic Resonance images. Existing automatic labelling methods are mostly statistical in nature and do not work very well in certain situations such as the presence of lesions. The goal is to assist them by a knowledge-based method. The system uses statistical method for generating a sufficie...

This paper discusses the design of integrity and derivation rules on the basis of Rule Markup Language (RuleML) and Semantic Web Rule Language (SWRL). We propose a general markup framework for integrity and derivation rules (R2ML). Rule concepts are defined with the help of MOF/UML, a subset of the UML class modeling language proposed by the Object Management Group (OMG) for the purpose of ’met...

Evidence-based medicine intends to optimize clinical decision making by using evidence. Semantic query answering could help to find the most relevant evidence. However, at point of care, it still lacks time for clinicians to do literature study. In this poster, we propose to build an evidence graph for clinical decision support, in which an evidence ontology is defined with extension of SWRL ru...

Résumé : Traiter et publier les données des sciences historiques dans le web sémantique constitue un défi intéressant où la représentation des aspects temporels joue un rôle clé. Nous proposons dans cet article un modèle de représentation des connaissances temporelles adapté au travail sur les documents historiques. Ce modèle est basé sur la notion de fluent que l'on représente dans des graphes...
