Reminder Subject: TALK: CURIOUS BROWSERS: Automated gathering of implicit interest indicators by an instrumented browser

Recommender systems provide personalized suggestions about items that users will find interesting. Typically, recommender systems require a user interface that can "intelligently" determine the interest of a user and use this information to make suggestions. The common solution, "explicit ratings", where users tell the system what they think about a piece of information, is well-understood and fairly precise. However, having to stop to enter explicit ratings can alter normal patterns of browsing and reading.

A more intelligent method is to use implicit ratings, where a rating is obtained by a method other than obtaining it directly from the user. Unfortunately, the ability of implicit ratings to predict actual user interest is not yet well-understood. Our research studies the correlation between various implicit ratings and the explicit rating for single Web pages.

We developed a Web browser, called the Curious Browser, to record various user actions (implicit ratings) during browsing and solicit explicit ratings for each page. The Curious Browser captures mouse clicks, mouse movements, scrolling and elapsed time. This was subsequently extended to include additional indicators such as mouse wheel activity, status bar changes, the size of the HTML file, the user's familiarity with the page, and a trace of the mouse coordinates.
