The proposal aims at generating computational mechanisms that will enable individuals to contribute towards making better collective decisions (e.g., news ranking) including crowdsourcing where aggregation of online noise answers can occur. The proposal brings together ideas from economics, statistics, and computation to expand the capabilities of social choice mechanisms to handle large numbers of alternative choices, to extract ground truth from aggregated preferences, and to address problems where individual agents might not be able to compare some alternatives. In contrast to classical social choice theory, which is limited to the selection between two alternatives, the project proposes a rigorous study of a model for computational choice that will be robust enough for discerning between thousands or even millions of alternatives.The proposal could have a profound impact in the way we build multi-agent systems, search engines and recommender systems. The proposed effort can serve as a catalyst in the growing area of computational social choice, including: (1) Rank aggregation has been used in many fields, involving some high impact applications like ranking of news. However, this problem is far from solved using traditional computational social choice methods because they either only work for two alternatives, require full rankings, does poorly in revealing the ground truth, or are hard to compute. The proposed research will develop new methodologies to overcome these deficiencies by designing objective, robust, and computable social choice mechanisms for rich preferences. (2) Crowdsourcing, whereby online workers' noisy answers are aggregated to produce a better overall answer to some question. This cannot be solved by existing computational social choice techniques as the online workers' answers are often partial orders, workers may manipulate the outcome by providing false answers, and the objective of aggregation is to reveal the true answer. The proposed research will directly tackle these challenges by designing new mechanisms, which are directly applicable to existing systems.

该提案旨在生成计算机制，使个人能够为做出更好的集体决策做出贡献（例如，新闻排名），包括其中可能发生在线噪声答案的聚集的众包。该提案汇集了经济学，统计学和计算的思想，以扩展社会选择机制的能力，以处理大量的替代选择，从聚合偏好中提取基本事实，并解决个体代理可能无法比较某些替代方案的问题。与仅限于两个选项之间的选择的经典社会选择理论不同，该项目提出了一个计算选择模型的严格研究，该模型将足够强大，可以在数千甚至数百万个选项之间进行识别。该提案可能对我们构建多代理系统，搜索引擎和推荐系统的方式产生深远的影响。所提出的努力可以作为计算社会选择领域的催化剂，包括：（1）排名聚合已被用于许多领域，涉及一些高影响力的应用，如新闻排名。然而，使用传统的计算社会选择方法远远不能解决这个问题，因为它们要么只适用于两个选择，需要完整的排名，在揭示地面真相方面做得很差，要么很难计算。拟议的研究将开发新的方法，以克服这些缺陷，设计客观的，强大的，可计算的社会选择机制丰富的偏好。 (2)众包，即在线工作人员的嘈杂答案被聚合，以产生一个更好的整体回答一些问题。这不能通过现有的计算社会选择技术来解决，因为在线工人的答案通常是偏序的，工人可以通过提供错误的答案来操纵结果，并且聚合的目标是揭示真实的答案。拟议的研究将通过设计直接适用于现有系统的新机制来直接应对这些挑战。
