In this paper we explore how two existing collaborative filtering algorithms can be enhanced by the calculation of demographic correlations among the members of user or item neighborhoods. Experiments are executed to evaluate the performance of the proposed approach. Their results show that demographic data can, in some cases, lead to the generation of more accurate predictions.

Methods Compiling data throughout the region and nationally, we considered two spatially based quantitative measures of endemism (relative range restriction): weighted endemism (WE) and corrected weighted endemism (CWE). In both measures, species are weighted by the proportion of their ranges found within the analysis window, with the ranges calculated as the total number of cells in which they...

Based on a cognitive notion of neo-additive capacities reflecting likelihood insensitivity with respect to survival chances, we construct a Choquet Bayesian learning model over the life-cycle that generates a motivational notion of neoadditive survival beliefs expressing ambiguity attitudes. We embed these neoadditive survival beliefs as decision weights in a Choquet expected utility life-cycle...
