FRAMEWORK FOR SELECTING AND DELIVERING ADVERTISEMENTS OVER A NETWORK BASED ON COMBINED SHORT-TERM AND LONG-TERM USER BEHAVIORAL INTERESTS

Targeted advertising content is provided for display in a page over a network in accordance with a technique in which advertisements are selected based on a determination of a user's short-term and long-term behavioral interests. Short-term and long-term information relating to a user's online activities is collected and associated with predetermined interest categories. Based on the collected information, short-term and long-term behavioral interest scores are determined for specific categories. The scores are employed to generate values for use in selecting advertisements. In one embodiment, a short-term score and two long-term scores are determined for one or more interest categories. A first long-term score models awareness with respect to a given category. A second long-term score and the short-term score are response-oriented scores that model the user's interest in making a response with respect to a given category, such as by purchasing a product or service within the category.
