Abstract

The Semantic Web is generally envisioned as a vast collection of document embedded knowledge that makes it highly improbable for agents traversing this space to know directly what entity, person, or organisation they are dealing with. In such an environment, the explicit representation of trust becomes an intrinsic part of calculating whether an agent can believe and use (or reuse) foreign sources. A key activity in this process is the step of integrating an agent’s ontology with that of another document found on the Web. To assist in calculating trust values for this purpose, Riposte provides a set of trust models and trust manipulation algorithms to create a dynamic model of author trust based on work that is being provided to an agent. Riposte is an ontology integration tool that uses suggestions and bases trust on whether an object in the provided ontology confirms or refutes current beliefs. The author can be assigned an initial trust value and this value is recalculated after the integration process.
