The part-of or part-whole construct is a fundamental element of many conceptual modeling grammars that is used to associate one thing (a component) with another thing (a composite). Substantive theoretical issues surrounding the part-whole construct remain to be resolved, however. For instance, contrary to widespread claims, the relationship between components and composites is not always trans...

The paper describes a prototype tool, named DIXSE, which supports the integration of XML Document Type Definitions (DTDs) into a common conceptual schema. The mapping from each individual DTD into the common schema is used to automatically generate wrappers for XML documents, which conform to a given DTD. These wrappers are used to populate the common conceptual schema thereby achieving data in...

The types of knowledge used during requirements acquisition are identified and a tool to aid in this process, ReqColl (Requirements Collector) is introduced. The tool uses conceptual graphs to represent domain concepts and attempts to recognise new concepts through the use of a matching facility. The overall approach to requirements capture is first described and the approach to matching illust...

Our study takes place in an European Project LIBRARIES named BAMBI (Better Access to Manuscripts and Browsing of Image). This paper presents a method for multilingual access information. Our approach uses a semantic structure in order to index a document without taking account of its language. This semantic structure is a hierarchical organisation of semantic elements. Each element contains two...

Two experiments provide evidence that our conceptual systems represent hierarchical relations between concepts in more than one way. Specifically, hierarchical relations may be represented via criteria inclusion or kind specification. The experiments provide the first evidence that these two ways of representing hierarchical relations mediate feature inheritance in systematically different ways...

cognitive science has found out that languages typically make use of conceptual metaphors to concretize abstract meanings. conceptual metaphor explains a target domain which is abstract via a source domain which is concrete. in other words, conceptual metaphor compares an abstract domain with a concrete one and thus makes it understandable for listeners/readers. this article studies the concept...

Kyoto Protocol allows developing countries to obtain technology transfer from developed countries under the framework of Clean Development Mechanism (CDM). Although South Africa is an ideal country to implement CDM projects, it lags behind many other countries in the number of CDM projects. This result prohibits South Africa to obtain technology transfer. This paper studies what licensing mode ...
