Both domain ontologies and Formal Concept Analysis (FCA) aim at modeling concepts, although with different purposes. In the literature, a promising research area concerns the role of FCA in ontology engineering, in particular, in supporting the critical task of reusing independently developed domain ontologies. With this regard, the possibility of(More)

E-mail address: anna.formica@iasi.cnr.it Fuzzy Formal Concept Analysis (FFCA) is a generalization of Formal Concept Analysis (FCA) for modeling uncertainty information. FFCA provides a mathematical framework which can support the(More)
In Object-Oriented databases, ISA hierarchy provides a powerful modeling tool that, through the inheritance mechanism, yields a coincise description of the world. In this paper, we tackle the problem of the correctness of ISA hierarchies in Object-Oriented database schemas. In general, the inheritance mechanisms proposed in literature do not preserve(More)
In this paper we propose a method to measure the semantic similarity of geographic classes organized as partition hierarchies within Naive Geography. The contribution of this work consists in extending and integrating the information content approach, and the method for comparing concept attributes in the ontology management system SymOntos developed at(More)
The possibility of assessing the similarity between concepts is growing in importance. One of the primary reasons for this is the development of the Net Economy that requires a high level of computer support and flexibility in doing business. In business transactions, similarity plays an important role. It is constantly used whenever certain goods or(More)
