The content and structure of a wiki evolve as a result of the collaborative eort of the wiki users. In semantic wikis, this also results in the evolution of the ontology that is implicitly expressed through the semantic annotations. Without proper guidance, the semantic wiki can evolve in a chaotic manner resulting in quality problems in the underlying(More)
We present the design of a computer-aided environment, RMCase, to support the design and construction of hypermedia applications. The environment is based upon the Relationship Management methodology. M C a s e supports hypermedia design and development activities. Support for cognitive design processes is achieved through three fundamental premises that(More)
Two fluorescent ligands, 3,5-dimethyl-4-(6'-sulfonylammonium-1'-azonaphthyl)pyrazole (dmpzn, 1) and 3,5-dimethyl-4-(4'-N,N'-dimethylaminoazophenyl)pyrazole (dmpza, 2) were obtained by condensation of ketoenolic derivatives with hydrazine. 1 and 2 formed the novel dinuclear complexes [(H(2)O)(3)ClRu(micro-L)(2)RuCl(H(2)O)(3)] (3 or 4) and(More)
We describe our experiences in designing and implementing a distributed system for real-time 3D-visualization. Then, we introduce a design approach to develop 3D virtual museums focusing in the hypermedia and spatial navigation. We show how to apply a hypermedia design model (OOHDM) to this kind of application and discuss its weakness to model spatial(More)
CO-Protégé is a set of plugins that extends Protégé-2000 in order to support a collaborative developing of an ontology. In Co-Protégé people do not make a direct edition of the shared ontology, but also they change it through the publication of ontological artifact. Co-Protégé users manage simultaneously two ontologies the private ontology and the shared(More)
This paper proposes a collective intelligence strategy for emerging semantic data. It presents a combination of social web practices with semantic web technologies to enrich existing web resources with semantic data. The paper introduces a social semantic tagging approach called Semdrops. Semdrops defines a conceptual model which is an extension of the(More)
The development of ontologies to the Semantic Web is based on the integration of existing ontologies favoring the modularization and reuse of them. These ontologies are used together in complex applications. However, how they are combined is usually hidden in the application code. The lack of an approach for explicitly expressing the way how ontologies are(More)
