Abstract

Abstract Shortlisting is the task of reducing a long list of alternatives to a (smaller) set of best or most suitable alternatives. Shortlisting is often used in the nomination process of awards or in recommender systems to display featured objects. In this paper, we analyze shortlisting methods that are based on approval data, a common type of preferences. Furthermore, we assume that the size of the shortlist, i.e., the number of best or most suitable alternatives, is not fixed but determined by the shortlisting method. We axiomatically analyze established and new shortlisting methods and complement this analysis with an experimental evaluation based on synthetic and real-world data. Our results lead to recommendations which shortlisting methods to use, depending on the desired properties.

不允许名单

摘要候选列表是将一长串备选方案缩减为一组(较小的)最佳或最合适的备选方案的任务。Shortlisting通常用于奖项的提名过程或推荐系统中，以显示有特色的对象。在本文中，我们分析了基于审批数据的候选名单方法，这是一种常见的偏好类型。此外，我们假设候选名单的大小，即最佳或最合适的备选方案的数量，不是固定的，而是由候选名单法确定的。我们公理化地分析了已建立的和新的入围方法，并以基于合成和现实世界数据的实验评估来补充这种分析。根据期望的属性，我们的结果会给出使用哪种候选方法的建议。

期刊介绍： Social Choice and Welfare explores all aspects, both normative and positive, of welfare economics, collective choice, and strategic interaction. Topics include but are not limited to: preference aggregation, welfare criteria, fairness, justice and equity, rights, inequality and poverty measurement, voting and elections, political games, coalition formation, public goods, mechanism design, networks, matching, optimal taxation, cost-benefit analysis, computational social choice, judgement aggregation, market design, behavioral welfare economics, subjective well-being studies and experimental investigations related to social choice and voting. As such, the journal is inter-disciplinary and cuts across the boundaries of economics, political science, philosophy, and mathematics. Articles on choice and order theory that include results that can be applied to the above topics are also included in the journal. While it emphasizes theory, the journal also publishes empirical work in the subject area reflecting cross-fertilizing between theoretical and empirical research. Readers will find original research articles, surveys, and book reviews.Officially cited as: Soc Choice Welf
