Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0030] Contract advertising is currently the mainstream form of display advertising, requiring multimedia resource providers to complete the corresponding delivery contract within a specified time period according to the targeting conditions of the advertiser. In general, the process can be seen as figure 1 The assignment problem on the shown bipartite graph G=(I∪J,E). Among them, I means that there are m multimedia display resources s 1 , s 2 , s 3 ..., s m A collection of display conditions, the display conditions of the multimedia display resources include the total delivery amount, delivery user attribute information, such as the delivery user's gender, age, location, etc.; J means that there are n multimedia resources d 1 、d ...

The invention discloses a method and device for determining a multimedia resource delivery strategy, and belongs to the field of Internet technologies. The method comprises the steps of generating a model function represented by a Lagrange function according to a dual algorithm, a multimedia resource delivery model and model restrictions; performing conversion on the model function to obtain a converted model function and an optimal solution expression of delivery strategy parameters; performing iterative calculation on a Newton iterative equation determined by the converted model function; obtaining a final value of a demand dual when the number of iterations reaches a preset number of times; and calculating an optimal solution according to the final value of the demand dual and the optimal solution expression. According to the invention, the Newton iterative equation is obtained through processing the converted model function, and thus the final value of the demand dual is obtained through performing iterative calculation on the Newton iterative equation. The equation is not required to be solved in each iteration process, and people only need to substitute the result of the previous iteration, so that the calculation complexity is reduced, and the calculation time is shortened.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for determining a multimedia resource delivery strategy. Background technique [0002] Contract advertising is a contract-based advertising model, which has become an important mode of modern advertising due to its advantages of speed, convenience, and flexibility. If the advertising order signed by the advertiser is called a multimedia resource, and the advertising space used to display the advertising order on the webpage is called a multimedia display resource, because in the actual delivery process, each multimedia resource has a delivery cycle, delivery times, delivery Location, delivery user attributes and other targeting conditions, and each multimedia display resource also has display conditions such as display location, display user attributes, etc. Therefore, how to determine the delivery strategy of multimedia resources to improve the accuracy ...
