Laureti, Paolo Moret, Lionel Zhang, Yi-Cheng 2004-09-11 We analyze some voting models mimicking online evaluation systems intended to reduce the information overload. The minimum number of operations needed for a system to be effective is analytically estimated. When herding effects are present, linear preferential attachment marks a transition between trustful and biased reputations. application/pdf https://folia.unifr.ch/global/documents/299596 https://folia.unifr.ch/documents/299596/files/1_zhang_apl.pdf eng http://arxiv.org/abs/cond-mat/0409020 info:eu-repo/semantics/altIdentifier/doi/10.1016/j.physa.2004.08.012 info:eu-repo/semantics/openAccess License undefined Physica A: Statistical Mechanics and its Applications. - 2005, vol. 345, no. 3-4, p. 705-712 info:eu-repo/classification/udc/53 Aggregating partial, local evaluations to achieve global ranking http://purl.org/coar/resource_type/c_6501
