    Abstract
    The intuitive simplicity of the so-called is-a (or subsumption) relationship has led to widespread ontological misuse. Where previous work has focused largely an the semantics of the relationship itself, we concentrate here an the ontological nature of its arguments, in Order to tell whether a single is-a link is ontologically well-founded. For this purpose, we introduce some techniques based an the philosophical notions of identity, unity, and essence, which have been adapted to the needs of taxonomy design. We demonstrate the effectiveness of these techniques by taking real examples of poorly structured taxonomies and revealing cases of invalid generalization.

    Abstract
    Defends the systematic introduction of formal ontological principles in the current practice of knowledge engineering, and explores the various relationships between ontology and knowledge representatiom. Presents recent trends in this research area. Compares the dichotomy between reasoning and representation to the philosophical distinction between epistemology and ontology. Introduces the notion of the ontological level, intermediate between the epistemological and conceptual levels as a way to characterize a knowledge representation formalism taking into account the intended meaning of its primitives
