Developed at UC Berkeley, "Opinion Space" (also known as The Collective Discovery Engine) is a social media technology designed to help communities generate and exchange ideas about important issues and policies. [1] Version 1.0 was launched on April 4, 2009 at UC Berkeley, and explored the question "Do you think legalizing marijuana is a good idea?" It has since undergone 4 different iterations, and been used in partnership with various organizations including The Occupy movement (Version 4.0, 5/24/2013 [2] ) and the African Robots Network (Version 4.0, 5/25/2013 [3] ). Opinion Space has also been used in collaboration with the United States State Department and the University of California's Berkeley Center for New Media (Version 2.0, 12/1/2009 [4] and Version 3.0, 2/25/2012 [5] ) to gain public perspective on foreign policy issues. Then U.S. Secretary of State Hillary Rodham Clinton explained, "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" (2010).
The website uses data visualization and statistical analysis to present and develop public opinion and ideas. Opinion Space is a self-organizing system that uses an intuitive graphical "map" that displays patterns, trends, and insights as they emerge and employs the wisdom of crowds to identify and highlight the most insightful ideas. The system uses a game model that incorporates techniques from deliberative polling, collaborative filtering, and multidimensional visualization.

Recommender systems are particularly useful when an individual needs to choose an item from a potentially overwhelming number of items that a service may offer.

The University of California, Berkeley, School of Information, also known as the UC Berkeley School of Information or the I School, is a graduate school and, created in 1994, the second newest of the schools at the University of California, Berkeley since the founding of the UC Berkeley College of Computing, Data Science, and Society in 2023. It was previously known as the School of Information Management and Systems (SIMS) until 2006. Its roots trace back to a program initiated in 1918 which became the School of Librarianship in 1926 and, with a broader scope, the School of Library and Information Studies in 1976. The program is located in the South Hall, near Sather Tower in the center of the campus.
Data and information visualization is the practice of designing and creating easy-to-communicate and easy-to-understand graphic or visual representations of a large amount of complex quantitative and qualitative data and information with the help of static, dynamic or interactive visual items. Typically based on data and information collected from a certain domain of expertise, these visualizations are intended for a broader audience to help them visually explore and discover, quickly understand, interpret and gain important insights into otherwise difficult-to-identify structures, relationships, correlations, local and global patterns, trends, variations, constancy, clusters, outliers and unusual groupings within data. When intended for the general public to convey a concise version of known, specific information in a clear and engaging manner, it is typically called information graphics.
Fernanda Bertini Viégas is a Brazilian computer scientist and graphical designer, whose work focuses on the social, collaborative and artistic aspects of information visualization.
Eric Paulos is an American computer scientist, artist, and inventor, best known for his early work on internet robotic teleoperation and is considered a founder of the field of Urban Computing, coining the term "urban computing" in 2004. His current work is in the areas of emancipation fabrication, cosmetic computing, citizen science, New Making Renaissance, Critical Making, Robotics, DIY Biology, DIY culture, Micro-volunteering, and the cultural critique of such technologies through New Media strategies.
Jock D. Mackinlay is an American information visualization expert and Vice President of Research and Design at Tableau Software. With Stuart Card, George G. Robertson and others he invented a number of information visualization techniques.
The California Institute for Quantitative Biosciences (QB3) is a nonprofit research and technology commercialization institute affiliated with three University of California campuses in the San Francisco Bay Area: Berkeley, San Francisco, and Santa Cruz. QB3's domain is the quantitative biosciences: areas of biology in which advances are chiefly made by scientists applying techniques from physics, chemistry, engineering, and computer science.

The Berkeley Center for New Media (BCNM) is a research, teaching, and public events program at UC Berkeley. Its mission is to critically analyze and help shape developments in new media from cross-disciplinary and global perspectives that emphasize humanities and the public interest. Founded in 2004 by Linda Williams, Ken Goldberg, Greg Niemeyer, Whitney Davis, and Cathy Koshland, the organization seeks to study new media from three disciplinary perspectives, the humanities, the arts, and technology. BCNM awards Designated Emphasis Degrees in New Media and Masters Certificates to graduate students and Undergraduate Certificates to undergraduate students at UC Berkeley.
Learning to rank or machine-learned ranking (MLR) is the application of machine learning, typically supervised, semi-supervised or reinforcement learning, in the construction of ranking models for information retrieval systems. Training data may, for example, consist of lists of items with some partial order specified between items in each list. This order is typically induced by giving a numerical or ordinal score or a binary judgment for each item. The goal of constructing the ranking model is to rank new, unseen lists in a similar way to rankings in the training data.

Marti Hearst is a professor in the School of Information at the University of California, Berkeley. She did early work in corpus-based computational linguistics, including some of the first work in automating sentiment analysis, and word sense disambiguation. She invented an algorithm that became known as "Hearst patterns" which applies lexico-syntactic patterns to recognize hyponymy (ISA) relations with high accuracy in large text collections, including an early application of it to WordNet; this algorithm is widely used in commercial text mining applications including ontology learning. Hearst also developed early work in automatic segmentation of text into topical discourse boundaries, inventing a now well-known approach called TextTiling.

The California Report Card (CRC) is a mobile-optimized web application designed to promote public involvement in the California government. Developed by Prof. Ken Goldberg and the CITRIS Data and Democracy Initiative at UC Berkeley with California Lt. Governor Gavin Newsom, version 1.0 was released in January 2014. On the CRC site, participants are encouraged to grade California on a scale from A+ to F on six timely topics and to propose their own suggestions of issues that merit attention at the state level. The CRC is a form of E-democracy, structuring and streamlining communication from the California residents to their elected officials.
