Abstract
Clinical archetypes are modular definitions of clinical data, expressed using standard or open constraint-based data models as the CEN EN13606 and openEHR. There is an increasing archetype specification activity that raises the need for techniques to associate archetypes to support better management and user navigation in archetype repositories. This paper reports on a computational technique to generate tentative archetype associations by mapping them through term clusters obtained from the UMLS Metathesaurus. The terms are used to build a bipartite graph model and graph connectivity measures can be used for deriving associations.

Notes
Elements in the openEHR Reference Model are in Courier font from here on.
Full ADL files for all the archetypes cited in this paper are available at http://openehr.org/knowledge/.
Further details can be consulted in the UMLS Reference Manual, http://www.nlm.nih.gov/research/umls/documentation.html.
A bipartite graph, bigraph or two-mode network is a network where vertices are divided into two sets and vertices can only be related to vertices in the other set [21].
Specialised archetypes use a differential style of declaration (i.e. the contents of a specialised entity are expressed as differences with respect to the parent). The .adls standard file extension has been introduced for differential ADL files while the .adl files are retained for standalone archetypes.
