A new perspective on instantiation
This paper develops a new perspective on the relation of instantiation.
This new perspective is based on recent research in cognitive
psychology, or, more specifically, on the theory of frames, which
was defined by Lawrence Barsalou to capture the common features
of contemporary models of human concepts. I show how this new
perspective may be applied to coordinate two rudimentary mental
operations: categorization and conceptualization

Two ontology-driven formalisations of functions and their comparison
In this paper, we give formalisations of two engineering concepts of technical function and present in more general terms the project of supporting functional description translation by ontological analysis. The formalisations are given within the foundational dolce ontology and the concepts formalised are as follows: (1) the function as defined in the Functional Representation approach by Chandrasekaran and Josephson and (2) the function as defined in the Functional Basis approach by Stone and Wood. These two concepts represent two main ways of understanding functions in engineering: the first by means of the behaviour of artefacts, and the second by means of operations on flows as performed by artefacts. We analyse the similarities and differences between these concepts by means of the formalisations and show how the formalisations support the automated translation between functional descriptions based on these two concepts. In addition, we compare our strategy of formalising different engineering concepts of function within one foundational ontology with other strategies in the ontology-driven formalisation, such as defining a single formalised concept of function, either for replacing existing engineering concepts, or for use as a reference by which such existing concepts can be related. We compare these strategies and sketch the merits and shortcomings of our strategy
