Proportional Rankings
In this paper we extend the principle of proportional representation to rankings. We consider the setting where alternatives need to be ranked based on approval preferences. In this setting, proportional representation requires that cohesive groups of voters are represented proportionally in each initial segment of the ranking. Proportional rankings are desirable in situations where initial seg...
متن کاملCollaborative Rankings
In this paper we introduce a new ranking algorithm, called Collaborative Judgement (CJ), that takes into account peer opinions of agents and/or humans on objects (e.g. products, exams, papers) as well as peer judgements over those opinions. The combination of these two types of information has not been studied in previous work in order to produce object rankings. Here we apply Collaborative Jud...
متن کاملSampling Rankings
Abstract In this work, I present a recursive algorithm for computing the number of rankings consistent with a set of optimal candidates in the framework of Optimality Theory. The ability to measure this quantity, which I call the r-volume, allows a simple and effective Bayesian strategy in learning: choose the candidate preferred by a plurality of the rankings consistent with previous observati...
متن کاملCounting Rankings
In this paper, I present a recursive algorithm that calculates the number of rankings that are consistent with a set of data (i.e. optimal candidates) in the framework of Optimality Theory. The ability to compute this quantity, which I call the r-volume, makes possible a simple and effective Bayesian heuristic in learning – all else equal, choose the candidate preferred by the highest number of...
متن کاملCorrelating Topic Rankings and Person Rankings to Find Experts
Expert search is about finding people rather than documents. The goal is to retrieve a ranked list of candidates with expertise on a given topic. The task is studied in the context of the enterprise track. We describe an approach that compares topic profiles and candidate profiles directly. These profiles are not based on unordered sets of documents, but on ranked lists. This allows us to diffe...
