OPRA: An Open-Source Online Preference Reporting and Aggregation System
This provides a tool for researchers and practitioners in need of computerized group decision support, but it is incremental as it builds on existing preference aggregation methods.
The authors tackled the problem of group decision-making by introducing OPRA, an open-source online system for reporting and aggregating preferences, which includes features like UI for rankings with ties, analytics, and support for combinatorial domains, and they applied it to an automatic mentor matching system.
We introduce the Online Preference Reporting and Aggregation (OPRA) system, an open-source online system that aims at providing support for group decision-making. 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 the development of computerized group decision support systems.
