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)
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)
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)
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)
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)
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)
