  abstract	= {There have been many approaches proposed for role mining.
		  However, the problems solved often differ due to a lack of
		  consensus on the formal definition of the role mining
		  problem. In this paper, we provide a detailed analysis of
		  the requirements for role mining, the existing definitions
		  of role mining, and the methods used to assess role mining
		  results.Given basic assumptions on how access-control
		  configurations are generated, we propose a novel definition
		  of the role mining problem that fulfills the requirements
		  that real-world enterprises typically have. In this way, we
		  recast role mining as a prediction problem.},
