Abstract: A technique called user views has recently been proposed to focus user attention on relevant information in response to provenance queries over workflow executions [1, 2]: Given user input on what modules in the workflow specification are relevant to the user, a user view is a concise representation that clusters together modules to create a small number of composite modules (or clusters) such that (1) each composite module in a user view contains at most one relevant (atomic) module, thus assuming the "meaning" of that module; and (2) no control or data dependencies (either direct or indirect) are introduced (soundness) or removed (completeness) between relevant modules. The goal is to find a user view with a smallest number of composite modules.
