Abstract: Methods and apparatus for managing models for classification of online users are disclosed. An example method includes determining a segment associated with a received impression, determining whether the received impression includes an indication that the received impression is the result of a conversion associated with the segment, determining a current ratio of converted to non-converted impressions associated with a classification model associated with the segment, determining a difference between the current ratio and a target ratio, and storing an indication of the received impression for use in at least one of training or updating a classification model associated with the segment when: (a) the difference does not meet a threshold or (b) counting the received impression in the ratio would reduce the difference.

Abstract: A method, system, and medium for managing modeled audience extension information that includes receiving tag information, the tag information comprising a user identifier corresponding to a user, a tag identifier, and one or more data values; adding the tag identifier and the one or more data values to a user object, wherein the user object is identified by the user identifier; assigning the user object to a segment based on the user object and a model, wherein the segment is identified by a segment identifier; and distributing the segment identifier and the user identifier to a market information buyer.

Abstract: A system and method for providing a targeting event marketplace is provided. Generally, the method contains the steps of: at least one targeted publisher and a targeting event marketplace entity agreeing to financial terms associated with revenues received from at least one buyer that obtains access to the Internet browser of an end-user; providing an end-user tag on a Web page of the Web site, wherein the end-user tag is capable of calling a Web server from an Internet browser of the end-user; analyzing an end-user action associated with the Web page, wherein the step of analyzing is performed to categorize the action into a category of targeting event; the Web server determining if at least one buyer has interest in at least one end-user taking an action that is categorized into at least one category of targeting event; and receiving bids from at least one buyer for providing access to the Internet browser of the end-user and selecting at least one buyer.
