    Résumé :
    Context is the set of assumptions, premises and inferences that allow us to share data, information, and knowledge and to transform them into understanding and ultimately into action and creation of wealth. The scale from data to information and to knowledge (and wisdom) is a continuous scale of increasing context independence. The Context Interchange research project of the Sloan School of Management at MIT and of the Laboratory of Electronic Commerce at the National University of Singapore aims at the design and development of theory, techniques, methodological elements, and tools for the integration of information. The COntext INterchange network (COIN) is a suite of tools for the integration of heterogeneous, distributed, and independent information sources over the Internet. The COIN strategy for the intelligent integration of information relies on the definition of contexts describing the semantic discrepancies among the component sources and the applications. The COIN wrappers extract data from Web sources and services. The COIN mediator automatically identifies and resolves the semantic conflicts arising when manipulating data in disparate contexts. We will present the context interchange strategy and tools and discuss various issues.
