User modeling with salience
First Claim
Patent Images
1. A method of using a user model with salience, the method comprising:
- providing a content item to a user through a user interface;
receiving physiological data corresponding to a physiological response of the user as the user interacts with the content item provided through the user interface;
determining a salience score for the content item based at least in part on the physiological response of the user;
updating a user model with the salience score for the content item;
determining a salience ranking for one or more keywords of the content item based on the salience score for the content item;
determining a relevance ranking for the one or more keywords of the content item based on the relevance of the one or more keywords to the content item; and
updating the user model to include a combined score for the one or more keywords of the content item based on the salience ranking and the relevance ranking;
wherein the salience ranking is at least partially based on the timing of determining the salience score for the content item.

Abstract
A method of using a user model with salience includes providing content to a user through a user interface. The method also includes receiving physiological data corresponding to a physiological response of the user as the user interacts with the content. The method may also include determining a salience score for the content based at least in part on the physiological response of the user, and updating a user model with the salience score.

16. A system of associating salience with a content item, comprising:
-
a user interface configured to present the content item to a user; a physiological sensor configured to record a physiological response of the user over time as the user interacts with the content item; and a controller communicatively coupled with the user interface and the physiological sensor, the controller configured to; provide the content item to the user interface for presentation to the user; associate the physiological response of the user with the content item as the user engages with the content item; determine a salience score for the content item based at least in part on the physiological response of the user; update a user model with the salience score for the content item; determine a salience ranking for one or more keywords of the content item based on the salience score for the content item; determine a relevance ranking for the one or more keywords of the content item based on the relevance of the one or more keywords to the content item; and update the user model to include a combined score for the one or more keywords of the content item based on the salience ranking and the relevance ranking; wherein the salience ranking is at least partially based on the timing of determining the salience score for the content item. - View Dependent Claims (17, 18, 19, 20)
