Merging Models Based on Given Correspondences Rachel Pottinger and Philip A. Bernstein   View Paper (PDF)   Return to Metadata & Sampling (Session C6) Abstract A model is a formal description of a complex application artifact, such as a database schema, an application interface, a UML model, an ontology, or a message format. The problem of merging such models lies at the core of many meta data applications, such as view integration, mediated schema creation for data integration, and ontology merging. This paper examines the problem of merging two models given correspondences between them. It presents requirements for conducting a merge and a specific algorithm that subsumes previous work. ©2004 Association for Computing Machinery
