Professor Olson's Athena Lecture was delivered at the ACM Conference on Computer-Supported Cooperative Work (CSCW), February 11-15, 2012, in Seattle, Washington.
ABOUT THIS AWARD
The ACM-W Athena Lecturer Award celebrates women researchers who have made fundamental contributions to Computer Science. Each year ACM will honor a preeminent woman computer scientist as the Athena Lecturer. Speakers are nominated by SIG officers. The Athena Lecturer will give a one-hour invited talk at an ACM conference determined by the speaker and the SIG which nominated her. A video of the talk will appear on the ACM website. The award includes travel expenses to the meeting and a $10,000 honorarium. Financial support for the Athena Lecturer Awards (2008-2009 through 2014-2015) is being provided by Google.
ACM-W Names Susan T. Dumais 2014-2015 Athena Lecturer
ACM-W named Susan T. Dumais of Microsoft Research as the 2014-2015 Athena Lecturer. Dumais introduced novel algorithms and interfaces for interactive retrieval that have made it easier for people to find, use and make sense of information. Her research, at the intersection of human-computer interaction and information retrieval, has broad applications for understanding and improving searching and browsing from the Internet to the desktop. The Athena Lecturer award celebrates women researchers who have made fundamental contributions to computer science. It includes a $10,000 honorarium provided by Google Inc.
“Dumais has helped us understand that the search is not the end goal,” said Mary Jane Irwin, who heads the ACM-W awards committee. “Her focus is on understanding when and why people search, and presenting results in context to help integrate those results into the larger search process. Her sustained contributions have shaped the thinking and direction of human-computer interaction and information retrieval, and influenced generations of student interns through collaborative projects with academic and industry partners.”
Dumais’ initial research demonstrated that different people use different vocabulary to describe the same thing, and that this mismatch limits the success of traditional keyword-based information retrieval methods. To build search systems that avoided the vocabulary problem, she and her colleagues invented Latent Semantic Indexing (LSI). A key feature of LSI is its ability to extract the latent conceptual structure from a large collection of texts by analyzing the associations between terms that occur in similar contexts, thus enabling a search engine to retrieve using concepts rather than keywords. Beyond information retrieval, LSI has been used to model various aspects of human cognition such as language acquisition and textual coherence.
Recently, Dumais’ research has analyzed how web content changes over time and how people revisit web pages, establishing that re-visitation patterns are influenced by user intent and changes in content. Her results have produced a retrieval model that uses web page changes to improve search ranking, and new tools to help people understand how the information they interact with changes over time in both expected and unexpected ways. Finally, her research on user modeling and context has enabled search engines to personalize search experiences for different individuals.
The author of more than 200 articles on information science, human-computer interaction, and cognitive science, Dumais holds several patents on novel retrieval algorithms and interfaces.
Yelick Named 2013-2014 Athena Lecturer
ACM named Katherine Yelick of the Lawrence Berkeley National Laboratory as the 2013-2014 Athena Lecturer. Yelick, also a professor at the University of California, Berkeley, has improved fundamental understanding and practice of parallel programming, which uses multiple processing elements simultaneously to solve a problem. She developed novel performance tuning, compilation and runtime systems, which implement the core behavior of computer languages.
"Yelick's innovative software is used in both the research community and in production environments," said Mary Jane Irwin, who heads the ACM-W awards committee. "She has taken on the challenges of software developers in the age of exascale computing and helped them become more efficient in this environment. An effective teacher and mentor, she been a role model for the computing community."
