COntext INterchange ( COIN ) System

The Context Interchange (COIN) System provides tools for representing, processing, and reconciling heterogeneous data semantics. In this demonstration we show how COIN can be used to automatically resolve semantic conflicts. We demonstrate support tools for developing COIN-compatible applications and show the representation and resolution capabilities in COIN. We then show how the domain application merging capabilities in COIN allow us to rapidly develop new applications which combine the domain models, context, and elevation axioms of existing applications. This is done without rewriting existing domain knowledge. Instead a tool is used to create linking axioms. We demonstrate the construction of a Travel Agent application by merging existing airfare and car rental applications. The new application combines the strength of both application domains and resolves their semantic differences.
