Ontology design is a complex and time-consuming process. It is extremely difficult for human experts to discover ontology from given data or texts. This paper presents a semi-automatic method for ontology extraction and design. The method is based on Formal Concept Analysis and a Horn clause model of a concept lattice. Inputs to the technique are domain-specific texts or data. After transformat...

User modeling is aimed at capturing the users’ interests in a working domain, which forms the basis of providing personalized information services. In this paper, we present an ontology based user model, called user ontology, for providing personalized information service in the Semantic Web. Different from the existing approaches that only use concepts and taxonomic relations for user modeling...

in this article, the ontology based approach for modeling and management of profiles and competencies in virtual organization breeding environment (vbe) is presented. the main aim of creating the profile and competency ontology of vbe participants is utilizing them in the development of the intelligent agent for choosing the best partners in order to perform the research projects in the informa...

Data modelling frameworks consist of a series of constructs which are used to create an abstraction of the world. Ontologies consist of concepts through which reality can be described. The aim of this paper is to use an ontology as a basis for comparing and evaluating data modelling frameworks. We begin by establishing a method for comparing modelling frameworks using ontology, and then examine...

Using MDA in ontology development has been investigated in several works recently. The mappings and transformations between the UML constructs and the OWL elements to develop ontologies are the main concern of these research projects. We propose another approach in order to achieve the collaboration between MDA and ontology technologies. We propose an ontology based model transformation infrast...

In this paper, we present a new approach that benefits from the advantages of both conceptual and ontological models in order to provide a powerful spatio-temporal data model for geographic information systems (GIS). We base our model on the MADS conceptual model that is transformed to a corresponding ontology model, using database to ontology mapping techniques and a set of transformation rule...

[1] Component-based modeling is an approach for simulating water resource systems where a model is composed of a set of components, each with a defined modeling objective, interlinked through data exchanges. Component-based modeling frameworks are used within the hydrologic, atmospheric, and earth surface dynamics modeling communities. While these efforts have been advancing, it has become clea...

Ontology has been widely applied in biological science (large-scale gene ontology), publishing field (Dublin-core standard and knowledge classification ontology), medicine and health care field (cancer ontology), culture inheritance field (museum and artist ontology). As the fundamental element of semantic web technology architecture, ontology provides expressive framework for knowledge reusabi...
