OO Analysis Patterns as UML Metalevel Collaborations

摘要

A criticism that could be made of the most commonly-used AI development methodologies, in particular that based on the widely-known KADS-CommonKADS expertise model, is the unsuitability of the available techniques for specifying and reusing knowledge-model patterns. In this article, we investigate the alternative of formulating knowledge model patterns as OO analysis patterns. We seek to take advantage of research on design pattern specification, aimed at modelling patterns by means of structural and behavioural "meta-level" constraints. We illustrate our argument with the formulation of an OO "assessment pattern".
