CS alumna Prof. Marti Hearst (B.A. ’85/M.S ’89./Ph.D. ’94, advisor: Robert Wilensky), whose primary appointment is in the School of Information, has been named to the 2021 inaugural class of the ACM Special Interest Group on Information Retrieval (SIGIR) Academy. SIGIR Academy membership recognizes the “principal leaders in IR” who have made “significant, cumulative contributions” to the development of the field, and whose “efforts have shaped the discipline and/or industry through significant research, innovation, and/or service.” Hearst literally wrote the first book on Search User Interfaces in 2009. She is known for her early work on automating sentiment analysis and word sense disambiguation, including the invention of an algorithm known as “Hearst patterns” which is widely used in commercial text mining applications including ontology learning. She also developed a now well-known approach to automatic segmentation of text into topical discourse boundaries, called TextTiling. Hearst is an Edge Foundation contributing author and a member of the Usage panel of the American Heritage Dictionary of the English Language. Her current research interests include user interfaces for search engines, information visualization, natural language processing, and MOOCs.
