BeliefOWL: An Evidential Representation in OWL Ontology
نویسندگان
چکیده
The OWL is a language for representing ontologies but it is unable to capture the uncertainty about the concepts for a domain. To address the problem of representing uncertainty, we propose in this paper, the theoretical aspects of our tool BeliefOWL which is based on evidential approach. It focuses on translating an ontology into a directed evidential network by applying a set of structural translation rules. Once the network is constructed, belief masses will be assigned to the different nodes in order to propagate uncertainties later.

An Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)
Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...
متن کاملUsing ontology for building distributed digital libraries with multimedia contents
This paper presents a new approach to build distributed digital libraries with multimedia contents. The authors propose a new scheme for media feature based concept modelling to address the limitation of traditional ontology based multimedia retrieval systems. The perceptual models can be used for semantic query processing using standard MPEG-7 media content descriptions. The authors have defin...
متن کاملProbabilistic Ontologies for Multi-INT Fusion
Systems are increasingly required to fuse data from geographically dispersed, heterogeneous information sources to produce up-to-date, mission-relevant results. These products focus not only on traditional military forces and systems, but to an increasing degree also on non-traditional combatants and their social networks. Successful multi-INT fusion requires that the constituent systems intero...
متن کاملBayesOWL: Uncertainty Modelling in Semantic Web Ontologies
It is always essential but difficult to capture incomplete, partial or uncertain knowledge when using ontologies to conceptualize an application domain or to achieve semantic interoperability among heterogeneous systems. This chapter presents an on-going research on developing a framework which augments and supplements OWL 5 for representing and reasoning with uncertainty based on Bayesian netw...
متن کاملAn Automated Transformation from OntoUML to OWL and SWRL
OntoUML and OWL are ontology languages appropriated to different knowledge representation levels. In order to have better knowledge representation and reasoning capabilities in OWL ontologies, an Ontology Engineering should be used – which corresponds to the transformation of a conceptual model ontology language, such as OntoUML, to a computational ontology language, such as OWL. This paper aim...
