Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 1 As shown, the steps of a method for measuring the contagion of a question-and-answer social network user sharing behavior of the present invention include:

[0025] S1: Obtain the user's existing historical behavior data, screen topics for formatting, and determine the user's personal attributes and the relationship between users;

[0026] S2: Numericalize and vectorize the Q&A data;

[0027] S3: Build a social network, analyze the network characteristics corresponding to each social network from the perspective of the network attributes, and analyze the factors affecting the contagion;

[0028] S4: Based on the common transmission route of information, the analogy tree model constructs multiple possible infection trees;

[0029] S5: After constructing all possible infection trees, calculate the infecti...

Abstract

The invention provides an infection intensity measurement method for user sharing behaviors of a question-answer social network, and the method comprises the steps: obtaining the existing historical behavior data of a user, and determining the personal attributes of the user and the attention relation between the users; performing numeralization and vectorization processing on the question and answer data; constructing a social network, and analyzing factors influencing the infectivity; constructing a plurality of possible infection trees by analogy tree models on the basis of common propagation paths of information; after all possible infection trees are constructed, calculating the infection probability between the nodes, and after the infection probability of all the nodes of the same infection tree is obtained, calculating the size of the infection force exerted by a certain user in the whole network. The factors such as the popularity degree, the activity degree and the attributeintegrity degree of the user knowledge sharing behaviors are more comprehensively considered, multiple possible infection networks are constructed based on the characteristics of the uncertain infection source to calculate the infection of the user, and the method for measuring the infection can be applied to multiple scenes in real life.

Description

technical field [0001] The invention relates to the field of information dissemination, in particular to a method for measuring the contagion of sharing behaviors of question-and-answer social network users. Background technique [0002] Behavioral contagion refers to the tendency and process in which individual behavior triggers the same behavior of related people. Specifically, when an individual's behavior is made in the network, it will stimulate his friends, and then the friends will show the same behavior. This phenomenon is called behavioral contagion. [0003] With the rapid development of network technology, virtual communities correspond to the emergence of social networks. People's communication is no longer limited by space, and a new medium is built for the dissemination of knowledge, which saves the time and cost of dissemination. On the one hand, it promotes the realization of knowledge sharing, and on the other hand, it promotes the development of question-a...
