Ed Huai-Hsin Chi (Chinese :紀懷新; Wade–Giles :Chi⁴ Huai²-hsin¹) (born c. 1973) is a Taiwanese American computer scientist and research scientist at Google, known for his early work in applying the theory of information scent to predict usability of websites.[ citation needed ]
Born and raised in Taipei, Taiwan, Chi moved to Minnesota in the 9th grade. He obtained his BA in 1994, his MA in 1996 and his PhD in 1999, all at the University of Minnesota.
After his MA graduation, Chi worked as a research scientist at Palo Alto Research Center (PARC) from 1997 to 2011. He started as an intern and was officially hired in 1999. From 1999-2007, he worked in the User Interface Research Group, during which time he was promoted to senior research scientist in 2005. He became area manager of the Augmented Social Group in 2007. In 2011, he left PARC and became a research scientist at Google, reporting directly to Peter Norvig in the areas of human-computer interaction and social computing. In 2017, he was promoted to principal scientist at Google, and to Distinguished Scientist in 2021.
In his spare time, Chi is an avid golfer, Taekwondo black belt, photographer, and snowboarder.[Ed Chi personal website]
Chi specializes in social computing and human-computer interaction. He has developed a computer system that predicts usability of Websites based on the theory of information scent, a theory by Peter Pirolli and Stuart Card that pioneered ways of understanding how people search for information online. He is also known for his work on information visualization and authored the book A Framework for Visualizing Information, [1] which describes approaches to make information visualization systems easier to develop through the use of reference models. His recent research has analyzed social behavior in large sociotechnical systems like Wikipedia, Twitter, and Digg, among other social software platforms. He has published over 80 academic articles, and he has over 20 patents. His top 9 publications have over 200 citations each.
Chi's dissertation, titled, "A Framework for Information Visualization Spreadsheets", was chaired by John T. Riedl. [2] The dissertation was an early example of the power of small multiples in information visualizations. During this time, he was awarded a University of Minnesota Graduate School Doctoral Dissertation Fellowship, Research Contribution Award, Doctoral Dissertation Award, and Best Teaching Award.
Chi has chaired top conferences and publishes regularly in top-tier academic conferences in computer science and human-computer interaction related fields. His work has been covered in various newspapers and magazines around the world, including The Economist , [3] Time , [4] Los Angeles Times , Technology Review , [5] and Wired . [6]
While at PARC, Chi published a paper [7] analyzing edits to Wikipedia, looking at content contributed vs the author's edit count.
In 2012, Chi served as the technical program co-chair for CHI, the most prestigious academic conference in the field of HCI. [8]
Chi was elected to the CHI Academy in 2018. [9] He was named to the 2022 class of ACM Fellows, "for contributions to machine learning and data mining techniques for social computing and recommender systems". [10]
In 2023, he was awarded the Distinguished Alumni award by the University of Minnesota Computer Science department.

Information foraging is a theory that applies the ideas from optimal foraging theory to understand how human users search for information. The theory is based on the assumption that, when searching for information, humans use "built-in" foraging mechanisms that evolved to help our animal ancestors find food. Importantly, a better understanding of human search behavior can improve the usability of websites or any other user interface.
Ben Shneiderman is an American computer scientist, a Distinguished University Professor in the University of Maryland Department of Computer Science, which is part of the University of Maryland College of Computer, Mathematical, and Natural Sciences at the University of Maryland, College Park, and the founding director (1983-2000) of the University of Maryland Human-Computer Interaction Lab. He conducted fundamental research in the field of human–computer interaction, developing new ideas, methods, and tools such as the direct manipulation interface, and his eight rules of design.
Stuart K. Card is an American researcher and retired senior research fellow at Xerox PARC. He is considered to be one of the pioneers of applying human factors in human–computer interaction. With Jock D. Mackinlay, George G. Robertson and others he invented a number of information visualization techniques. He holds numerous patents in user interfaces and visual analysis.
George William Furnas is an American academic, Professor and Associate Dean for Academic Strategy at the School of Information of the University of Michigan, known for his work on semantic analysis and on human-system communication.

GroupLens Research is a human–computer interaction research lab in the Department of Computer Science and Engineering at the University of Minnesota, Twin Cities specializing in recommender systems and online communities. GroupLens also works with mobile and ubiquitous technologies, digital libraries, and local geographic information systems.
Social translucence is a term that was proposed by Thomas Erickson and Wendy Kellogg to refer to "design digital systems that support coherent behavior by making participants and their activities visible to one another".
Wikipedia Review is an Internet forum and blog for the discussion of Wikimedia Foundation projects, in particular the content and conflicts of Wikipedia. Wikipedia Review sought to act as a watchdog website, scrutinizing Wikipedia and reporting on its flaws. It provides an independent forum to discuss Wikipedia editors and their influence on Wikipedia content. At its peak, participants included current Wikipedia editors, former Wikipedia editors, users banned from Wikipedia, and people who had never edited. Though the site is still partially running, the last post was on 31 May 2012.

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.
Sheelagh Carpendale is a Canadian artist and computer scientist working in the field of information visualization and human-computer interaction.
Social visualization is an interdisciplinary intersection of information visualization to study creating intuitive depictions of massive and complex social interactions for social purposes. By visualizing those interactions made not only in the cyberspace including social media but also the physical world, captured through sensors, it can reveal overall patterns of social memes or it highlights one individual's implicit behaviors in diverse social spaces. In particular, it is the study “primarily concerned with the visualization of text, audio, and visual interaction data to uncover social connections and interaction patterns in online and physical spaces. ACM Computing Classification System has classified this field of study under the category of Human-Centered Computing (1st) and Information Visualization (2nd) as a third level concept in a general sense.
