About CAFÉ

With support from USAID and the Development Impact Lab at UC Berkeley, the CITRIS Data and Democracy Initiative is developing a new social media platform that directly engages citizens and communities from developing regions to collectively assess conditions, needs, and outcomes related to engineering innovations in humanitarian assistance, solar energy, democracy and governance, and global health.

In contrast to polls and surveys that are extremely valuable for analysts, CAFÉ is user-facing: the CAFÉ platform will provide direct, immediate visual feedback to participants, allowing them to instantly understand where they stand on key issues with respect to other participants, and encourage open-ended qualitative responses that can enhance interaction between users. Like a coffeehouse, we envision CAFÉ as a grassroots, user-friendly, self-organizing environment that allows the wisdom of crowds to identify, highlight, and display patterns, trends, and insights as they emerge. To facilitate interactions, CAFÉ will incorporate techniques from deliberative polling, collaborative filtering, and multidimensional visualization.

Opinion Space, a precursor to CAFÉ that focused on social innovation, has been used since 2010 by the U.S. State Department. Thousands of participants from around the world use it to organize, visualize, and analyze constructive suggestions on foreign policy:

"Opinion Space will harness the power of connection technologies to provide a unique forum for international dialogue. This is … an opportunity to extend our engagement beyond the halls of government directly to the people of the world."
U.S. Secretary of State Hillary Clinton (2010)

Developer Resources

Malasakit is a variant of CAFÉ originally intended for assessing disaster risk reduction strategies in the Phillipines. Malasakit was developed and deployed through a partnership between UC Berkeley and National University in the Phillipines through the Philippine-California Advanced Research Institutes (PCARI) Project.

However, Malasakit can be applied to a variety of domains, and has been designed with the open-source community in mind. For instance, Free Speech on Free Speech was deployed in collaboration with the Berkeley Center for New Media to assess attitudes towards free speech and safety issues on university campuses. The following resources are available to anyone who would like to contribute to the project:
