Embodiment Construction

[0043] The present invention will be further described below by taking the student card swiping transaction log generated by the student card management system of a certain domestic college as an example in conjunction with the accompanying drawings.

[0044] A university in China manages the student card usage of students through the student card management system. The system generates approximately 2,000,000 student card swiping transaction logs per month. figure 2 This is a sample transaction log generated by the system. Each piece of data records information such as card swiping serial number, user ID, user name, merchant ID and name of consumption, time of card swiping, amount of consumption, and POS machine ID of card swiping. Each transaction log records a student's card swiping behavior. College friends usually tend to consume at the same time, such as going to the cafeteria to eat at the same time, go to the supermarket to shop at the same time, and go to the libra...

Abstract

The invention belongs to the field of social network analysis data mining, and particularly relates to a method for establishing a social network based on transaction log data. According to the method, the transaction log data generated by a modern software system such as an ERP system, an MIS and a CRM system are mined, and the social network among system users can be established based on a true environment to be used for social network analysis. The method involves a data pre-processing module, a co-occurrence matrix generation module and a social network establishing module. According to the method for establishing the social network based on the transaction log data, the transaction log data generated by the modern software system are pre-processed first, wherein pre-processing includes data impurity cleaning, time mark determining, space mark determining and the like; then, a weighting co-occurrence matrix of the system users can be calculated by the co-occurrence matrix generation module according to transaction user using system behavior characteristics; finally, a social relation existence coefficient based on an edge weight and JACCARD relational coefficient is defined to be used for judging a true social relation, and accordingly a trusted social network can be established from the co-occurrence matrix.

Description

technical field [0001] The invention belongs to the technical field of social network analysis, and in particular relates to a social network construction. Background technique [0002] Social Network Analysis (Social Network Analysis) is a specification and method for analyzing the relationship structure and attributes of social networks, focusing on the relationship and structure among participants and their impact on participating individuals and the entire group. Social network analysis has been widely used and played an important role in the analysis of occupational mobility, the impact of urbanization on individual well-being, and the analysis of world political and economic systems. In recent years, social network analysis has increasingly become a hot research issue in the field of data mining, and has received extensive attention from academia and industry. [0003] In research related to social network analysis, the quality and scale of social network data are two...
