Embodiment Construction

[0024] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] At present, in order to protect user privacy and enterprise data security, enterprises in different industries cannot share data. For the same user, enterprises in different industries may collect different information about the user. For example, taking a 4S shop as a user, for the same 4S shop (Automobile Sales Service shop 4S, 4S shop for automobile sales service), the bank may collect information such as the credit limit, assets and l...

Abstract

The invention provides a recommendation model construction method and device, and belongs to the technical field of computers. The method comprises the following steps: 1, preparing raw materials; receiving first sample data sets sent by a plurality of second servers respectively, decrypting the first sample data set according to a preset decryption algorithm, and obtaining a plurality of second sample data sets, obtaining a plurality of sample data of at least one same user in the plurality of second sample data sets according to a preset rule, combining the plurality of sample data of each same user to obtain a target sample data set, and constructing a recommendation model according to the target sample data set. Third-party server, the sample data of each enterprise is encrypted and then sent to a third party for processing; the third party constructs a recommendation model through the target sample data set, data sharing of all enterprises is achieved through the third party server, data barriers among the enterprises are broken through, a more accurate recommendation model can be obtained, and the recommendation accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and device for constructing a recommendation model. Background technique [0002] With the development of computer technology, how to recommend products that meet user needs and improve recommendation efficiency has become the focus of attention of all walks of life. [0003] It has become a common recommendation method to collect a large amount of user information, build a recommendation model based on the large amount of user information, and recommend information to users through the recommendation model. The construction of a recommendation model requires a large amount of user information, and the more information collected, the more accurate the recommendation model will be. However, due to reasons such as protecting user privacy and corporate data security, companies with different user information cannot share data. However, an accurate recommenda...
