Problems solved by technology

This method does not take into account the common situation of terminal relocation among merchants, and only uses the time difference, especially the minimum time and average time to determine adjacent merchants, and there is a certain error
[0009] (3) Using seed merchants as the center point of the business circle, clustering through transaction intervals can be used as a method to establish a business circle. However, due to the characteristics of bank card transactions—high amount and low frequency, there may be merchants in a certain business district with In the case that the seed merchant has no direct transaction connection, in the clustering method, since the merchant has no direct connection with the seed merchant, it is likely to be considered to be too far away from the seed merchant and be eliminated, so this method also has defects

Embodiment Construction

[0055] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.

[0056] First, the principle of the method for establishing a business district model based on the random walk algorithm of the present invention will be described.

[0057] The establishment method of the business circle model of the present invention is realized based on the random walk algorithm, specifically, the relationship between merchants is described by using the consumption behavior of the cardholder, and the merchants belonging to the same business circle are obtained through the different relationships between the merchants . Among them, the so-called random walk (Random walk), also known as random walk, is a mathematical statistical model, which consists of a series of trajectories, each of which is random, and it c...

Abstract

The invention relates to a business circle model building method and a building system thereof. The method comprises a transaction data obtaining step of obtaining transaction data of all merchant nodes in a prescribed area; a merchant model diagram constitute step of establishing a merchant model diagram compose of all merchant nodes based on that transaction data; a seed merchant selection stepof selecting a specific merchant node as a seed merchant in the merchant model diagram; and a business zone model calculating step of calculating a business zone model in the prescribed area based ona random walk algorithm starting from the seed merchant in the merchant model diagram. According to the invention, the business circle model can be established efficiently without manual visit.

Description

technical field [0001] The invention relates to data processing technology, in particular to a method for establishing a business district model based on a random promulgation algorithm and a system for establishing a business district model. Background technique [0002] At present, there are mainly three methods for determining merchant business districts: [0003] (1) The business district is defined by the address information of the merchant. The address information of the merchant generally includes information such as XX Road XX, etc. By delineating the geographic location range of the business district, it is determined whether the merchant address is included in the geographical location of the business district. Realize the determination of the business district to which the merchant belongs; [0004] (2) Realize the definition of the business district by analyzing the transaction data, and realize the determination of the business district to which the merchant be...
