This paper presents a formal framework for the combination of multiple sources of evidence in an information retrieval domain. Previous approaches which have included additional information and evidence have primarily done so in an ad-hoc manner. In the proposed framework, collaborative and content information regarding both the document data and the user data is formally specified. Furthermore, the notion of user sessions is included in the framework. A sample instantiation of the framework is provided.
