Refinement hierarchies in structural conceptual models

ABSTRACT
Refinement hierarchies have been widely studied and applied in many different fields of Computer science. Seen from a conceptual modeling perspective, refinement essentially concerns the hierarchical organization of a set of concepts regarding entities of a given domain. Research on the modeling of the static aspects of entities, and their hierarchical organization, has produced a significant amount of results that can be found in the literature. However, very often it is not easy to read and compare results coming from different fields. There are different perspectives, the terminology greatly varies, the basic assumptions are different and the underlying semantics may hide discrepancies that are difficult to discover. The intent of this paper is to provide a survey about a set of relevant proposals coming from three important fields of Computer Science: Artificial intelligence (and, in particular, Knowledge representation), Programming languages, and Databases. Furthermore, in the paper a reference frame is proposed, to be used for an homogeneous presentation of the different proposals, and a deeper understanding of refinement hierarchies.
