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 semantic-based criteria for purposive statistical aggregation. The unambiguous communication of complex and detailed medical concepts is now a crucial feature of(More)
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)

The paper presents a review of the ONIONS project. ONIONS is committed to developing a large-scale ontology library for medical terminology. The developed methodology exploits a description logic-based design for the modules in the library and makes extended use of generic theories, thus creating a stratification of the modules. Terminological knowledge is(More)
We present the most applicable aspects of our research in the conceptual integration of terminologies. From past experience, we claim that the conceptualizations provided for terminological ontologies need to be philosophically and linguistically grounded. We developed ONIONS, a methodology for integrating domain terminologies by exploiting a library of(More)
We collected a set of words, suffixes, and idioms regarding actions in surgical procedures, ie. "deeds" as defined in a CEN European Prestandard; we then searched for their definitions in different authoritative sources and we performed an ontological analysis of this material according to the ONIONS methodology. The result was a formal model on surgical(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)
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)
