Abstract

The invention discloses a method for designing an advertisement click rate prediction system in a mobile application. The method comprises the following steps: carrying out integration, cleaning and transformation preprocessing on advertisement data; generating features by using the preprocessed advertisement data and constructing a feature complete set; carrying out effective feature selection onthe feature complete set, and selecting an effective feature set; and training an advertisement click rate prediction model by using the effective feature set. According to th method for predicting an advertisement click rate in a mobile application, the long-tail data in the advertisement data is classified according to the similarity and the data valuing frequency, so that the defect that information hidden in the long-tail data cannot be effectively utilized in the prior art is overcome, the information in the long-tail data is fully utilized, and the prediction effect is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for designing a click rate prediction system for advertisements in mobile applications. Background technique [0002] In recent years, with the rapid development of the mobile Internet, a mobile ecosystem composed of developers, application markets, users, advertisers and other roles has gradually formed. In this ecosystem, mobile in-app advertising is one of the main sources of revenue for mobile applications, and accurate advertising placement is the key to increasing advertising revenue. The focus of improving the click-through rate of advertisements is to construct an effective prediction model of click-through rate of advertisements to find the most matching advertisements for users. As one of the key technologies for accurate advertisement placement, advertisement click-through rate prediction has attracted extensive attention from academia and industry. [...
