In application areas like personal information agents user modelstypically maintain sophisticated representations of personal interest profiles. Theserepresentations can be utilized for personalized information presentation. Information support in Organizational Memories mainly address the same goals, but prevalently derive actual information needs from task and role specific informationneeds. In this paper, we present the Frodo architecture for business-process oriented knowledgemanagement. Task-, user-, and role-driven aspects of information needs are modeled separately and then amalgamated into a specific context for information supply. A description of several usage scenarios elaborates on the assembly of a concrete information need for knowledge retrieval. Thepaper concludes with the description of an application domainthat serves as a testbed for the proposed concepts.
