....The minimal scope is a set of terms that is necessary to support the communication within the KRAFT network. The domain analysis is based on the idea that changes within ontologies are inevitable and the means to handle changes should be provided. The authors pursue a domain led strategy [Paton et al. 1991] , where the shared ontology fully characterizes the area of knowledge in which the problem is situated. Within the ontology formalization phase the fully characterized knowledge is defined formally in classes, relations and functions. The top level ontology is needed to introduce predefined ....

....ontology, which allows alternative mapping functions to be defined between ontologies. In order that the network can easily incorporate additional functionality, the shared ontology should not be limited to the minimal scope defined during stage (iii) Rather, we pursue a domain led strategy (Paton et al. 1991) whereby the shared ontology fully characterises the field of knowledge that the problem being addressed is situated in. For example, in the student transfer problem, this methodology requires that the domain of higher education be defined by the shared ontology. This approach facilitates the ....

.... [Hobbs 1985, Hirst 1991] In other areas of AI, some interest in ontology has been shown in the past in natural language understanding [Hobbs et al. 1987, Bateman et al. 1990, Klose et al. 1992] and knowledge acquisition [Alexander et al. 1986, Monarch and Nirenburg 1987, Wimmer and Wimmer 1992, Paton et al. 1993]. In the latter field, ontological issues have recently gained some popularity due to the knowledge sharing initiative [Neches et al. 1991, Musen 1992, Gruber 1993, Gruber 1994, Pirlein and Studer 1994] it should be noticed, however, that in the knowledge sharing community the term ontology ....

....in the construction, maintenance and evolution of a domain depend on theories for their existence. Such models, and the theories which form them, have both a cognitive and social nature. This is based on a realist understanding of science as described by Harr. 14, 15, 16] and elaborated in [38]. The argument now developed can be used to account for models of domains and can also be used to describe models of knowledge acquisition. We restrict it to the former category in this section. Having defined the hermeneutic approach (section 2) we now provide its underpinning (this section) and ....

....(sections 4 and 5) The basic assumption of our method is that humans construct models in order to deal with the complexities of the real world and these are formed by abstraction; by simplifying complexity. The philosophical and cognitive justification for this approach is discussed more fully in [38]. The real world, that is, that which is referenced, has observable and non observable features. In the simplest case a model is produced by abstracting from what is observable alone (left hand side of Figure 1) This kind of model will lack explanatory power because it cannot account for the ....
