About COMSOC@BGU 2023

Computational social choice is a discipline at the interface of social choice theory and computer science. It is concerned with the application of computational techniques to the study of social choice mechanisms, and with the integration of social choice paradigms into computing (read more).

The 9th International Workshop on Computational Social Choice (COMSOC) will take place on 3-5 July 2023, at Ben-Gurion University of the Negev, Beersheba, Israel. The aim of the workshop is to bring together different communities: computer scientists interested in computational issues in social choice; people working in artificial intelligence and multiagent systems who are using ideas from social choice to organize societies of artificial software agents; logicians interested in the logic-based specification and analysis of social procedures; computer science theorists analyzing algorithmic properties of social phenomena; and — last but not least — people coming from social choice theory itself: economists, mathematicians, and political scientists.

Call for Papers

Submissions of papers describing original, under review, or recently published work on all aspects of computational social choice are invited. Topics of interest include, but are not limited to computational issues that arise in the analysis of:

  • Voting and collective decision-making
    • Axiomatic properties
    • Manipulation, control, and bribery
    • Voting equilibria and dynamics
    • Delegation, proxy voting, and liquid democracy
    • Participatory budgeting
  • Preference representation and elicitation
  • Opinion diffusion and aggregation on social networks
  • Peer Evaluation
  • Judgement aggregation, belief aggregation, and epistemic voting
  • Fair division, allocation, and matching
  • Coalition formation
  • Recommendation systems

We welcome theoretical, empirical and experimental work on these topics, including, in particular, research on algorithms (exact, approximate, parameterized, online and distributed), learning, logic, and simulations in the context of social choice.

All submitted papers will be reviewed by the program committee. Accepted papers will be collected in informal workshop notes, as the workshop has no formal proceedings and the authors retain their copyright. To accommodate the publishing needs of different scientific communities, we stress that authors will retain the copyright of their papers and that submitting to COMSOC 2023 does not preclude publication of the same material in a journal or in a conference with formal proceedings. Each accepted paper will have to be presented by one of the authors, with the constraint that each workshop participant gives at most one talk (exceptions can be made due to unforeseen circumstances).

Submission Guidelines

Regular papers should not exceed 12 pages in length, excluding references, contact information, acknowledgements, and a clearly-marked appendix of arbitrary length that will be read at the discretion of the PC members. When preparing your submission, please follow these formatting instructions. The easiest way of doing so is to use the Latex typesetting system with the class file comsoc2023.cls. The formatting instructions are based on a sample file (comsoc2023.tex), which you can use as a starting point for your own paper (download full example from here).

Submission is done through CMT: You can revise your submission any number of times before the deadline.

Anonymous Submissions

COMSOC does not require anonymous submissions, but this is allowed (e.g. in case you want to comply with anonymity requirements of other conferences, or for any other reason). In order to support this, the reviewing system is anonymous, but authors can write their names, as is done usually in camera-ready versions. Authors that do not wish to do so will maintain their anonymity.

Invited Speakers

Robert Aumann picture

Robert Aumann is a Professor of Mathematics at the Hebrew University of Jerusalem, and one of the founders of the Center for Rationality at the Hebrew University. He is one of the world's leading game theorists, and the author of almost a hundred scientific papers and six books. He is a member of the American Academy of Arts and Sciences, the National Academy of Sciences, the British Academy, the Academia Europaea and the Israel Academy of Sciences and Humanities; holds honorary doctorates from the Universities of Chicago, Bonn, Louvain, City University of New York, Bar Ilan University, Ben Gurion University of the Negev, and the University of Paris II; and has received numerous prizes, including the Nobel Memorial Prize in Economic Sciences for 2005 for his work on repeated games.

Itzhak Gilboa picture

Itzhak Gilboa holds the AXA Chair in Decision Sciences at the École des Hautes Études Commerciales (HEC) Paris, as well as the Chair of Economic Theory and Decision Theory at Tel-Aviv University. He works in decision theory and other fields in economic theory such as game theory and social choice. His main research areas are decision under uncertainty, focusing on the definition of probability, notions of rationality, non-Bayesian decision models, and related issues. He is a Fellow of the Cowles Foundation for Research in Economics at Yale University, a Fellow of the Society for the Advancement of Economic Theory, a Member of Council of the Econometric Society, and an International Honorary Member of the American Academy of Arts and Sciences.

Sarit Kraus picture

Sarit Kraus is a Professor of Computer Science at Bar-Ilan University. Her research focuses on intelligent agents and multi-agent systems ---particularly the design of intelligent agents that can interact proficiently with people, in both cooperative and conflicting scenarios. Her work combines methods from Machine Learning, Decision Theory and Game Theory, non-classical logic, optimization under uncertainty and psychology. Kraus was awarded the IJCAI Computers and Thought Award, ACM SIGART Agents Research award, ACM Athena Lecturer, the EMET prize and was twice the winner of the IFAAMAS influential paper award. She is AAAI, ECCAI and ACM fellow and a recipient of the advanced ERC grant. She is a member of The Israel Academy of Sciences and Humanities.

Eric Maskin picture

Eric Maskin is the Adams University Professor and Professor of Economics and Mathematics at Harvard, and was previously the Albert O. Hirschman Professor of Social Science at the Institute for Advanced Study. He has made contributions to game theory, contract theory, social choice theory, political economy, and other areas of economics, and the author of more than 140 scientific papers and five books. He is a Fellow of the American Academy of Arts and Sciences, Econometric Society, Game Theory Society, and the European Economic Association, and a Corresponding Fellow of the British Academy, and a past president of the Econometric Society. He holds honorary doctorates from the University of Cambridge, the Hebrew University of Jerusalem, Corvinus University of Budapest, Université Libre de Bruxelles, and Georgetown University, among others. In 2007, he was awarded the Nobel Memorial Prize in Economics for laying the foundations of mechanism design theory.

Visa Requirement

Visitors from most OECD countries are exempt from visitor visa. See full list here.

If you require a visa to enter, please see the details in the Israeli government page. Several countries without diplomatic relations with Israel require special Foreign Ministry confirmation to issue a visa, requiring a formal invitation (which we can provide). Please contact Omer Lev to request one.
