....5, 6] Integration is only possible if there is a common language which can be shared amongst applications for representing what clinical users have said and done. Even without the requirement for integration, more expressive representations are a requirement for many single applications, e.g. [11, 12]. Indeed, one author has cited establishing a common controlled vocabulary for medicine as the number one grand challenge for medical informatics [7] A number of the prominent efforts to provide more formal representations for medical concepts are based on ontologies expressed in ....

....needs of different applications. Once the taxonomies are properly disentangled and made orthogonal, each application or user can be accommodated by appropriately defined composites such as Symptom . We have yet to encounter a convincing counterexample. Of other authors, those, such as Zweigenbaum [11], who require taxonomies to be strict trees and do not provide multiple classification through descriptions, have focused on specialised applications; those such as Cimino who have allowed uncontrolled multiple hierarchies, have found themselves with hierarchies which are difficult to maintain ....

....the number of combinations to N) In the UMLS metathesaurus, the preferred terms play the role of pivot for the different synonyms. For representing complex relationships between concepts, the formalism of conceptual graphs has been proposed by several group as a pivot representation mechanism [42 44]. The problem behind this approach is obviously to guaranty that the meaning is preserved during the two transformations that are effected. The Planner The planner optimizes the conversion process. More precisely, in presence of two argument descriptors, the planner produces a strategy in term ....

....November 1995. natural language. Aiming for such a normalised conceptual representation is by no means a trivial task, and raises the issue of its production from natural language input. The very design of the representation is itself a fundamental point, which we have addressed elsewhere [7, 8]. In this paper, we first recall the general objectives of the Menelas project and its architectural principles. We then describe the implemented prototype and its results. We finally discuss the issues raised and the experience gained from the project. PROJECT OBJECTIVES The overall objectives ....

These components have been implemented in prolog, lisp, c and c, and run on Unix; the consultation user interface runs on PC. Given input coming from different languages, or even within a single language, starting from variable surface forms, the analysis system must provide a canonical ....

We therefore set up some methodological and theoretical principles to enforce this conformity [Bouaud et al. 1994, Zweigenbaum et al. 1995, Bouaud et al. 1995] We examined formalism choices at the symbol level: tree rather than lattice or DAG structure for the subsumption hierarchy, and constraining relation signatures. We also proposed principles that help a knowledge engineer satisfy the constraints induced by these choices. ....
