Abstract

The difficulty inherent in schema matching has ledto the development of several generic match algorithms.This paper describes how we adapted generalapproaches to the specific task of aligning two ontologiesof human anatomy, the Foundational Model ofAnatomy and the GALEN Common Reference Model.Our approach consists of three phases: lexical, structuraland hierarchical, which leverage different aspectsof the ontologies as they are represented in ageneric meta-model. Lexical matching identifies conceptswith similar names. Structural matching identifiesconcepts whose neighbors are similar. Finally,hierarchical matching identifies concepts with similardescendants. We conclude by reporting on the lessonswe learned.
