Method for using most influential node in social network to achieve efficient viral marketing

Abstract

The invention discloses a method for using a most influential node in a social network to achieve efficient viral marketing. The method for using the most influential node in the social network to achieve efficient viral marketing sequentially includes the steps of user definition and resource definition, establishment of edge connection for relationships between users and resources, establishment of interest strength between every two users, definition of importance measure indexes of weighted network nodes in boundary viewing dimension, calculation of a sum of edge weights in an NN assembly in a weighted network, establishment of a marketing model and the like. According to the method for using the most influential node in the social network to achieve efficient viral marketing, attention records between the users and the resources in the real social network are used, user interests are found, user interest strength relational diagrams are constructed, common attention of the users is used, on this basis, a half-partial centrality method based on neighborhood information is adopted to determine influential nodes, the nodes serve as initial nodes, spread of marketing information is carried out on a user interest network, key factors which can well restore interpersonal interaction processes in real life and comprise the accumulation effect, the social reinforcement effect and friend relationship strength are introduced into a spreading model, and the method for using the most influential node in the social network to achieve efficient viral marketing has the advantages of being low in calculated amount and good in robustness.

Description

【Technical field】 [0001] The invention relates to a network marketing method, in particular to a method for realizing efficient virus marketing by utilizing the most influential nodes on a social network. 【Background technique】 [0002] With the development of Web2.0 technology, a new generation of social networks has emerged rapidly.

Problems solved by technology

Therefore, the study of viral marketing with the help of the information dissemination model ignores the difference between individual behaviors in information dissemination and viral marketing, and cannot truly reflect the characteristics of viral marketing. Strong ties and weaker ties are more conducive to the dissemination of information between nodes. The relationship in the real world is usually represented as a weighted network: friends are divided into close friends. The probability is large, and vice versa is small; and the unauthorized network cannot accurately describe the closeness of the node relationship in viral marketing
