Embodiment 1

[0022] figure 1 It shows the implementation flow of the method for recommending ranking provided by Embodiment 1 of the present invention, which is described in detail as follows:

[0023] It should be noted that, in this embodiment and the following embodiments, the recommendation system generates a preliminary recommendation result, the preliminary recommendation result is a vector with a dimension of n, and each recommendation item of the preliminary recommendation result includes the recommended item id, recommendation degree .

[0024] In step S101, according to the preset correlation factors, define the recommended correlation function, recommended ranking function and related average precision RMAP function

[0025] In this embodiment, it is first necessary to determine the preset correlation factors that affect the ranking of recommended items from among the many correlation factors that affect the ranking of recommended items. The preset correlation factors include b...

Abstract

The invention is suitable for the technical field of information treatment, and provides a method and a system for recommending an order. The method comprises the steps of defining a recommending correlation function, a recommending ranking function and a related mean accuracy remote memory access protocol (RMAP) function according to preset correlation factors; obtaining the optimal RMAP and corresponding optimal recommending explanation correlation, the optimal real-time correlation and the optimal diversity according to the primary recommending result and the RMAP function; obtaining a ranking value of recommending items corresponding to the optimal RMAP according to the optimal recommending explanation correlation, the optimal real-time correlation and the optimal diversity; and generating a recommending list according to the ranking value sequence recommending items. By adopting the method and the system disclosed by the invention, the recommending items meet the user requirements, and have wide degree of coverage, and diversity in the generated recommending list.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a method and system for recommending sorting. Background technique [0002] With the development of information technology and the Internet, people have gradually entered the era of information overload from the age of information scarcity. In this era, both users and information producers have encountered great challenges. As a user, how to find the information of interest from a large amount of information is a very difficult thing. As an information producer, how to make the information you produce stand out and be welcomed by users is also a very difficult thing. [0003] Existing recommendation systems can use domain-based collaborative filtering algorithms, content-based algorithms, or matrix factorization algorithms to generate preliminary recommendation results. In the general architecture of recommendation systems, this preliminary recommenda...
