Integrating Two Descriptions of Taxonomies with Materialization.
Alain Pirotte, David Massart · The Journal of Object Technology · 2004
This paper presents a precise correspondence between two views of taxonomic hierarchies: an intensional view based on concepts and an extensional view based on categories, i.e., subsets of the population of individuals analyzed in terms of these concepts.The correspondence is described with materialization, a generic relationship defined for object-oriented and entity-relationship information models.The paper introduces materialization and shows how it provides a systematic bridge between both views of taxonomies.
