E-learning is gaining momentum in corporate settings as an alternative and supplementary solution to learning and performance problems. Users of e-learning applications and courses differ across regional, linguistic, and country boundaries and user requirements are strongly influenced by their local cultural perspective. Thus e-learning design needs to be sensitive to cultural parameters. Yet, ...

the study deals with the possibility of information loss in web 2.0 due to the interaction between the overload and the real information. using gottesman and preskill method, this investigation has proposed a mechanism to calculate the amount of information transformation in web 2.0. in this proposal, there are three different hilbert spaces that belong to the degrees of freedom of outside, ins...

Patent data provide technological information essential to define strategies and decisions in the context of firm innovative processes. At present, information regarding patents is usually represented and stored in large databases. Information from these databases is commonly retrieved in the form of files with a CSVor XML-based codification but with little semantics that enable the inference o...

Apart from completeness usability, performance and maintainability are the key quality aspects for Web information systems. Considering usability as key implies taking usage processes into account right from the beginning of systems development. Context-awareness appears as a promising idea for increasing usability of Web Information Systems. In the present paper we propose an approach to conte...

Concept naming over the taxonomic structure is a useful indicator of the quality of design as well as source of information exploitable for various tasks such as ontology refactoring and mapping. We analysed collections of OWL ontologies with the aim of determining the frequency of several combined name&graph patterns potentially indicating underlying semantic structures. Such structures range ...

We propose a model for providing integrated and unified access to multiple information sources. Each information source comprises two parts: (a) an ontology i.e. a set of terms structured by a subsumption relation, and (b) a database that stores objects under the terms of the ontology. We assume that the objects of interest belong to an underlying domain that is common to all sources (e.g. a se...
