....developed a methodology for representing Controlled Medical Terminologies (CMTs) as Object Oriented Databases (OODBs) to provide support for comprehension of their structure and content. The comprehension support was achieved via the schema layer which gives an abstract view of the source CMT. In [7,8], we described how the schema layer of the Medical Entities Dictionary (MED) 9] helped to uncover and correct errors and inconsistencies in its content. In this paper, we utilize an OODB representation to capture the knowledge of the Metathesaurus (META) and the Semantic Network. META is a ....

....in vocabulary orientation and comprehension by providing an abstraction of the underlying CV contents. The schematic representation also helps in uncovering errors and inconsistencies that may have been introduced into a CV during its original development and subsequent refinement and expansion [13, 14]. In its original form, the OOVR methodology was presented as a two phase process, with an initial phase followed by a refinement phase [19, 20] In this paper, we first give a unified presentation of the methodology and prove some formal characteristics of OOVR representations. We also present a ....

....layer gives an abstract view of the large and complex source CMT, which aids 2 in the comprehension of its structure and content. At the concept layer, users can directly access objects which denote concepts of the original CMT and obtain any detailed terminologic knowledge they require. In [15, 16], we described how our previous work on the schema layer of the Medical Entities Dictionary (MED) 17] helped its designer to uncover and correct some errors and inconsistencies in the MED s original modeling and to improve its content. In this paper, we utilize an OODB representation to capture ....

....As previously noted, the Metathesaurus and the Semantic Network of the UMLS are related by associating each concept of the Metathesaurus with one or more semantic types. The Semantic 4 Network provides a high level abstract view of the Metathesaurus. Note the difference from our previous work [15, 16, 11, 12] on OODB modeling of CMT, which totally lack such a high level view. In general, a class in an OODB schema represents a group of objects (or instances) which exhibit the same properties and have a common semantics. The OODB schema gives an abstract view of a database. In order to model the UMLS as ....
