US Patent 10134044 Collection and use of fine-grained user behavior data

A user behavior monitoring module logs the operation of an image browser and sends the logged information to a personalization system. The personalization system includes a monitoring management module, a client statistics data store, a recommender system, and a content refinement module. The monitoring management module receives the logged information sent by the user behavior monitoring module and stores it in the client statistics data store. The recommender system determines user preferences based on the information stored in the client statistics data store. The content refinement module refines a set of content items based on the user preferences determined by the recommender system. The set is refined so that the resulting content items (and their ordering) are more relevant to the user operating the image browser. The refined set of content items is displayed to the user by the image browser.
