The increasing development of legal ontologies seems to offer satisfactory solutions to legal knowledge formalization, which in past experiences lead to a limited exploitation of legal expert systems for practical and commercial use. The paper describes some ontology-based tools that enable legal knowledge formalization. Jurwordnet is an extension to the(More)
Paper-based terminology systems cannot satisfy anymore the new desiderata of healthcare information systems: the demand for re-use and sharing of patient data, their transmission and the need of semanticbased criteria for purposive statistical aggregation. The unambiguous communication of complex and detailed medical concepts is now a crucial feature of(More)
We describe ONIONS, a methodology for integrating ontologically-heterogeneous taxonomic knowledge and its current application to medical domain. Some clarification is given of our intended meaning of ontology and related notions, then main problems of ontology design are addressed, with a short comparison with alternative approaches. The methodology is(More)
ONIONS helps terminological ontology construction from existing, contextually heterogeneous terminologies. It is a methodology for integrating the context-dependent conceptualizations underlying conceptually heterogeneous terminology systems. We describe an application of this methodology to the medical domain with an example extracted from the UMLS system.(More)
Guidelines for clinical practice are being introduced in an extensive way in more and more different fields of medicine They have the potential to improve the quality and cost-efficiency of care in a complex health care delivery environment. Computerization may increase the effectiveness of both the information retrieval of guidelines and the management of(More)
Although is recognized that ontologies may help building better and more interoperable information systems, there is skepticism on the real impact they may have in the future. We believe that ontologies will succeed in the information system arena and no systems will ever be designed without an ontological approach. In this paper we demonstrate the(More)
Polysemy is a bottleneck for the demanding needs of semantic data management. We suggest the importance of a well-founded conceptual analysis for understanding some systematic structures underlying polysemy in the medical lexicon. We present some cases studies, which exploit the methods (ontological integration and general theories) and tools (description(More)
