We illustrate OPRA’s distinctive features: UI for reporting rankings with ties, comprehensive analytics of preferences, and group decision-making in combinatorial domains. We also discuss our work in an automatic mentor matching system. We hope that the open-source nature of OPRA will foster development of computerized group decision support systems.}, number={18}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Chen, Yiwei and Qian, Jingwen and Wang, Junming and Xia, Lirong and Zahavi, Gavriel}, year={2021}, month={May}, pages={16011-16013} }
