Update on GDN 2021: 21st International Conference on Group Decision and Negotiation

February 26, 2021


Dear Colleagues:


The preparation for a virtual GDN 2021 conference is going well. We would like to provide an update on preparing for GDN 2021 (http://gdnconference.org/gdn2021/ ).


1.     Accepted GDN 2020 Submissions. As announced on March 25, 2020, submissions accepted for GDN 2020 are automatically accepted for GDN 2021. We welcome authors, whose submissions were accepted by GDN 2020, to present their work at GDN 2021.


Full-length and extended abstracts accepted for GDN 2020 have been published in the 2020 Springer or Local Conference Proceedings. We would like to ask the authors of the submissions accepted by GDN 2020, who are interested to present their work at GDN 2021, to send one-paragraph abstracts to GDN 2021 using the EasyChair submission system by April 9, 2021. Kindly follow the format provided in the conference template when preparing such abstracts. We have created a special stream entitled “Accepted for GDN 2020” for those abstracts on the EasyChair submission system. Please select this stream when you upload your one-paragraph abstract. Those abstracts will be included in the GDN 2021 Local Conference Proceedings. Since those abstracts will also appear in the GDN 2021 Local Proceedings, we encourage you to properly modify the title and abstract so that they are different from ones that appeared.


For those authors whose short abstracts were accepted for GDN 2020, but not included in the GDN 2020 Local Proceedings, please send your abstracts to GDN 2021 using the EasyChair submission system by April 9, 2021 to indicate your interest in presenting your paper at GDN 2021 and select the “Accepted for GDN 2020” stream.


2.     GDN 2021 Presentations. We plan to hold GDN 2021 virtually using the Zoom platform. A 15-minute live or pre-recorded presentation will be scheduled for each paper. However, in order to avoid potential issues arising because of internet connectivity, we would like to ask each presenter to send us a 15-minute pre-recorded presentation in advance. Details about how to send the recorded presentations will be communicated later.


3.     GDN 2021 Registration Fees. We have reduced the GDN 2021 Registration Fees significantly. Please see the attached file for details. Registration page and payment by credit cards will be operational soon.

This conference provides a forum for those working in the field, bringing together researchers from Africa, the Americas, Asia, Europe, and Oceania.
GDN series of conferences have provided a stimulating environment for the dissemination of state-of-the-art knowledge in the field of group decision and negotiation, allowing for intense discussions among participants and the exchange of ideas and critical comments for further improvement.
GDN 2021 topics will be organized in several streams and include all aspects of group decision and negotiation such as
  • Technological Foundations
  • Systems Design and Use
  • Methodological Foundations
  • Theoretical Foundations
  • Behavioural Aspects
  • Applications

There will be a dedicated student track offering pre-doctoral students an opportunity to present (preliminary) work and to receive valuable feedback.

Conference proceedings will be published in a volume of Springer Lecture Notes in Business Information Processing (LNBIP), as well as a local proceedings volume for authors who choose to retain copyrights to their papers. Selected papers will be considered for publication in the Springer journal Group Decision and Negotiation.
