Dr. Marti Hearst is a Professor in the School of Information at the University of California in Berkeley (USA). She defended her PhD in Computer Science at the University of California in 1994. Her research is focused on design, development and evaluation of the systems for information access. She has developed several innovative information visualization and text analysis techniques including TextTiling, TileBars and the Cat-a-Cone. In the recent Flamenco project she explores the use of faceted metadata to improve searching for information for general public; this design is now used on hundreds if not thousands of websites worldwide. She has studied the effects of social computer-mediated communication on blogs, online dating, and collaborative knowledge creation.
