Description
Technical Field
The invention relates to the technical field of advertisement putting, in particular to an advertisement propagation method for large-scale crowd orientation and dynamic scene matching.
Background
With the development of technology and the transition of times, the development of outdoor advertisements is driven by programming-digitization-datamation, and the 'precision' and 'data support' are essential characteristics of the continuous improvement of the advertising effect in the intelligent advertisement operation mode, and the business mode change of the advertising industry is necessarily evolved around the basic logic of the improvement of the technology-datamation driven advertising effect, and even the business mode change is defined as the 'original year' of the programming intelligence of the outdoor advertisements in 2021.
Tracing the development of the advertising media industry, it can be found that the traditional advertising transaction and propagation mode is a pure linear mode, and advertisers directly purchase media advertising spots through agents, so that the system has absolute control right, the reach of users and audiences, and the effect is not regarded. With the popularization of the internet, a large amount of user behaviors are digitalized. The big data analysis processing technology can directly help the advertiser to more accurately locate and find the target crowd. Therefore, a data management platform of an integrated user, an advertisement demand side platform for helping an advertiser analyze data and perform advertisement putting, and a media supplier platform for gathering more media long-tail resources are gradually formed, and an advertisement trading platform for connecting all supply and demand and data resources and providing trading places is generated, so that a systematic and automatic programmed purchase and information propagation mode is formed. As shown in fig. 1, this phase is referred to as "automated information pushing phase based on programmed digitization", and in this phase, programmed purchasing of advertisements to advertisement propagation develops from a programmed mode, and it realizes programmed docking between advertisers, agents and network media in a digitized, automated and systematic manner, helps advertisers to accurately find target audiences and users associated and matched with advertisement information, and makes programmed delivery implement automation of the whole outdoor advertisement industry chain through the whole process from advertisers to media to exposure. The method has the greatest characteristic of realizing automation of a series of processes such as programmed medium purchasing, advertisement putting, put report feedback and the like in an advertisement propagation mode of programmed putting.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an advertisement propagation method for large-scale crowd orientation and dynamic scene matching, which segments and clusters a target audience through the driving of data, and accurately outlines a target consumer portrait; the accuracy of advertisement putting and audience reaching is improved, different advertisements represent different commodities, and the advertisement player is suitable for different crowds.
Aiming at the problems in the prior art, the invention provides an advertisement propagation method for large-scale crowd orientation and dynamic scene matching, which comprises the following steps:
(1) the dynamic user accurate portrait sketching is realized in different outdoor scenes by utilizing the movement detection technology of a camera or a probe;
(2) calculating in real time, and finding the optimal and most matched advertisement aiming at a target audience in a dynamic scene and time period through a bidding algorithm;
(3) the user portrait is merged by analyzing the vehicle information of the user, the user portrait and the big data of the user behavior, and the user portrait becomes more accurate through a machine learning algorithm model;
(4) through user feedback when the advertisement is watched, the user portrait is corrected, and the user portrait is more accurate through a correction algorithm, so that more advertisements are accurately thrown.
