Hi ruby folks, I would like annonce the release of a gem called "acts_as_meritocracy". This gem is a mixin enabling a weighted majority voting system for any model with qualitative decisions/categories. As measure of consensus/inter-rater agreement, you can choose between a weighted variant of the Fleiss’s Kappa (by default) or the entropy of the distribution of votes. The consensus score is in the interval [0,1]. very high consensus=1 , very low consensus=0 NOTE: this voting system has been developed to take (collective) a decision about items, not rank items (e.g. by popularity). i.e. generally once a certain level of consensus is reached on a given item, a decision is taken and the vote is close. more info: https://github.com/nmaisonneuve/acts_as_meritocracy -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
