      "content": "**arXiv**: http://arxiv.org/abs/1704.01420v3\n\nMost past work on social network link fraud detection tries to separate genuine users from fraudsters, implicitly assuming that there is only one type of fraudulent behavior. But is this assumption true? And, in either case, what are the characteristics of such fraudulent behaviors? In this work, we",

      "content": "**arXiv**: http://arxiv.org/abs/1601.01228v1\n\nFinancial fraud detection is an important problem with a number of design aspects to consider. Issues such as algorithm selection and performance analysis will affect the perceived ability of proposed solutions, so for auditors and re-searchers to be able to sufficiently detect financial fraud it is",
