Abstract: Methods and systems for establishing a click-through rate estimation model. A computing device may extract basic characteristics corresponding to a current language channel associated with a server provider. The computing device may combine the basic characteristics to obtain a combination characteristic. The computing device may further obtain an effective high-order characteristic based on the basic characteristics and the combination characteristic and calculate a weight of the effective high-order characteristic. The computing device may generate the CTR estimation model by applying a CTR equation to the weight corresponding to effective high-order characteristic. The implementations may not be limited by human factors, therefore achieving high efficiency in establishing CTR estimation models and high accuracy of the CTR estimation model.
