Node recommendation method and system based on reliability model

Abstract

The invention provides a node recommendation method and a system based on a reliability model. The method comprises steps: A1, the number of the first type of nodes and the number of the second type of nodes are counted, and the interaction history between the first type of nodes and the second type of nodes is stored to a corresponding two-dimensional matrix respectively; A2, according to a matrix algorithm and an iterative algorithm, the reliability grades of the first type of nodes and the reliability grade of the second type of nodes are obtained respectively; and A3, according to the reliability grade of each of the first type of nodes, a plurality of the first type of nodes are recommended for the second type of nodes as trusted nodes, or, according to the reliability grade of each of the second type of nodes, a plurality of the second type of nodes are recommended for the first type of nodes as trusted nodes. An error threshold is set, the reliability grade errors can be effectively controlled, the calculation is simple and accurate, promotion is easy, and the method and the system are applicable to network transaction, market evaluation ranking, enterprise reliability ranking and management on teaching teacher and student information, and can design customized and self-defined recommendation service.

Description

technical field [0001] The present invention relates to the technical field of information services, in particular to a node recommendation method and system based on a credibility model. Background technique [0002] With the development of Internet technology, various servers need to calculate the credibility of network nodes and provide users with node credibility levels. However, the credibility level results in existing technical solutions are not reliable. It is often easily disturbed by the interaction history data of network nodes. [0003] After searching, we found the following 2 authorized invention patents in China: [0004] Existing technology 1: Patent No. ZL201210201114.3--credit rating system and method based on matching credit rating and default loss rate; [0005] Existing technology 2: Patent No. ZL201210279363.4--a dynamic web service trust evaluation method based on user honesty; [0006] The system proposed in prior art 1 is composed of a data analys...

Problems solved by technology

[0008] The problem to be solved by the present invention is similar to that of the prior art 1 and the prior art 2, and belongs to the same technical field, but the method of the prior art cannot be applied to other network nodes, the main reason being that it is impossible to establish an accurate Algorithms to deal with interactive operational behavior; and no error limits are introduced, making the results of the confidence level unreliable
