....of concepts as classification trees is one of the main steps in ontology development. Taxonomic analysis, during which hierarchical relationships in a domain should be identified and represented, is defined as a distinct stage in the latest version of the ONIONS approach to ontology development [19]. These methodologies are mainly concerned with the organisation of the various activities that an ontological engineer engages in and providing a means of managing the many products of the ontology development process. There has been a necessary focus on what must be done in the development of ....

....it is suggested that categories are often formed on the basis of temporary goals. It is often difficult to know which concepts such be defined as classes in an ontology and how to define those classes that we choose to include in our ontology. The context sensitivity of an ontology is discussed in [19], where it is suggested that the meaning of terms depends on the context in which a term appears and the context in which the term is used. They suggest that an ontology should only be specified as far as the context of use requires. As an example of context sensitive membership from the ....

.... about 40 vocabularies that contain approximately 500 thousand biomedical concepts and over 1 million terms to describe them (Humphreys, 1998) The Medical Ontology Group of Italian National Research Council has been working on integrating and reusing existing terminological ontologies in medicine (Steve, Gangemi Pisanelli, 1997). Steve et al. have designed an ontology library ON9, which is written in Ontolingua (Gruber, 1992) and Loom (MacGregor, 1993) It includes thousands of medical concepts and organizes them into domain, generic and meta level theories. They use a methodology called ONIONS to aid construction of ....

....of concepts as classification trees is one of the main steps in ontology development. Taxonomic analysis, during which hierarchical relationships in a domain should be identified and represented, is defined as a distinct stage in the latest version of the ONIONS approach to ontology development [2]. Although the representation of hierarchical knowledge is widely seen as an important aspect in the design of a formal ontology, very little advice is available on the problems that may be encountered during this process and how such problems can be addressed. Furthermore, the advice that is ....

The context sensitivity of an ontology is discussed in [2], where it is suggested that the meaning of terms depends on the context in which a term appears and the context in which the term is used. As an example of context sensitive membership of a class, consider the classification of the chemical bonds that exist between biological molecules. There are ....

....and its results The relevance of generic (domain independent) theories to the development of ontologies is not always recognized. There is a number of significant experiences showing that an ontological analysis can profit from theories which are philosophically and linguistically grounded [7] 8][9]. Examples of generic theories include: mereology or theory of parts, topology or theory of wholes and connexity, morphology , or theory of form and congruence, localization theory, time theory, actors theory, etc. Our position is that generic theories are essential to the development ....

....systems that provide services, such as formal contexts and concept classification, which greatly help the development of domain theories by specializing generic theories. We developed ONIONS, a methodology for integrating domain terminologies by exploiting a library of generic theories [9]. Aims of ONIONS include: Developing a well tuned set of generic ontologies to support the integration of relevant domain ontologies in medicine. In fact, current medical ontologies mostly lack axiomatization, or semantic precision, or ontological cleverness. Integrating a set of relevant ....

Introduction ONIONS methodology for ontology integration has been developed since 1992 to account for the problem of conceptual heterogeneity [12] 37][38]. It also addresses some problems encountered in the context of the European project GALEN [11] and the Italian projects SOLMC (Ontologic and Linguistic Tools for Conceptual Modelling) 16] and ONTOINT (see the URL: http: saussure.irmkant.rm.cnr.it onto ontoint.html) It is being applied in a ....

The role of ontologies to allow a more effective data and knowledge sharing is widely recognized [17] 18] ONIONS (ONtological Integration Of Naive Sources) methodology for ontology integration [54] has been developed since the early 1990s to account for the problem of conceptual heterogeneity. It addresses some problems encountered in the context of the European project GALEN [14] and the Italian projects SOLMC (Ontological and Linguistic Tools for Conceptual Modeling) 21] and ONTOINT ....

....ONIONS (ONtological Integration Of Naive Sources) is a methodology for conceptual analysis and ontological integration and its products are supposed to support any level of interoperability, if used within appropriate systems ( 3. 2) For an abstract and comprehensive description of ONIONS, see [54]. The current implementation of the methodology employs Loom [36] a knowledge representation system that supports classification services based on of a quite expressive description logic. ONIONS implementation is meant to provide extensive axiomatization, clear semantics, and ontological depth to ....
