The role of data mining in pharmacovigilance
Expert Opinion on Drug Safety, 2005A principle concern of pharmacovigilance is the timely detection of adverse drug reactions that are novel by virtue of their clinical nature, severity and/or frequency. The cornerstone of this process is the scientific acumen of the pharmacovigilance domain expert.

Devising a complete and correct set of roles has been recognized as one of the most important and challenging tasks in implementing role-based access control. A key problem related to this is the notion of goodness/interestingness—when is a role good/interesting?

Proceedings of the 15th ACM symposium on Access control models and technologies, 2010
There has been increasing interest in automatic techniques for generating roles for role based access control, a process known as role mining. Most role mining approaches assume the input data is clean, and attempt to optimize the RBAC state. We examine role mining with noisy input data and suggest dividing the problem into two steps: noise removal and

An optimization framework for role mining
Journal of Computer Security, 2014Role Based Access Control (RBAC) is accepted as the de facto access control model for organizations of all sizes. However, engineering the right set of roles is crucial to enable the correct deployment of RBAC within an organization. Indeed, discovering an optimal and correct set of roles from existing permission assignments, referred to as the role ...

Mining the Technical Roles of GitHub Users
Information and Software Technology, 2021Abstract Context:Modern software development demands high levels of technical specialization. These conditions make IT companies focus on creating cross-functional teams, such as frontend, backend, and mobile developers. In this context, the success of software projects is highly influenced by the expertise of these teams in each field. Objective:In

Algorithms for mining meaningful roles
Proceedings of the 17th ACM symposium on Access Control Models and Technologies, 2012Role-based access control (RBAC) offers significant advantages over lower-level access control policy representations, such as access control lists (ACLs). However, the effort required for a large organization to migrate from ACLs to RBAC can be a significant obstacle to adoption of RBAC. Role mining algorithms partially automate the construction of an

Role mining based on cardinality constraints
Concurrency Computation Practice and Experience, 2015SummaryRole mining was recently proposed to automatically find roles among user‐permission assignments using data mining technologies. However, the current studies about role mining mainly focus on how to find roles, without considering the constraints that are essentially required in role‐based access control systems.

ON THE ROLE OF INTERPRETABILITY IN FUZZY DATA MINING
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2007Data Mining, a central step in the broader overall process of Knowledge Discovery from Databases, concerns with discovering useful properties, called patterns, from data. Understandability is an essential — yet rarely tackled — feature that makes resulting patterns accessible by end users.

PostProcessing in Constrained Role Mining
2018Constrained role mining aims to define a valid set of roles efficiently representing the organization of a company, easing the management of the security policies. Since the associated problems are NP hard, usually some heuristics are defined to find some sub-optimal solutions.
