Computational social choice is a rapidly evolving research trend concerned with the design and analysis of methods for collective decision making. It combines methods from computer science with insights from economic theory. COST Action IC1205 on Computational Social Choice is a European research network that has been set up to provide a common platform for research in this field across Europe and beyond.
Within this project, we focus on the specification and verification of voting schemes (a.k.a. voting rules). A voting scheme, as a method to combine individual preferences to an aggregated election result, is part of the fundamental democratic principles. It is thus vital that voting schemes are working as intended. Existing voting schemes have shown undesired and sometimes surprising properties (e.g., negative voting weights in federal elections in Germany) — for more complicated, newly designed voting schemes which become possible due to computer assistance in the vote counting process, these issues are likely to emerge as well.
The goal of this project is to develop formal verification techniques which allow to check properties of voting schemes without the huge overhead of user interaction needed in full functional verification. The resulting methodology could then be used in an iterative design and implementation process of new voting schemes.
Findings within this project are furthermore applied within FairNet RIC:
The FairNet Research and Innovation Center aims at enabling an internet that offers a variety of value-oriented services among which consumers can choose from easy to manage, transparent, and reliable options.
Values are abstract concepts of the desirable and exist on an individual, economic as well as on a business level. Internet-based services are value-based and this often results in value conflicts between consumers, providers, and governance-stakeholders.
These close interdependencies between informative, social, regulatory and economic aspects constitute a challenge for research and practice.
In the FairNet RIC, researchers from various disciplines – computer science, information systems, psychology, business administration, economics, ethics and law – collaborate interdisciplinary to facilitate the socio-technical design of value-oriented Internet-based services.
