In this paper, the relationship between personality traits and the parameters of certain social networks is investigated directly through data collection by precise questionnaire surveys. First, social network analysis is employed to calculate multiple parameters of the networks. Then, a correlation analysis is conducted on the relationship between the personality traits and the parameters. The results show that some network parameters are in consistent with the students’ personality traits. Results also reveal that the parameters of the respondents who mark themselves as “extroverted” are much closer to those of respondents who mark themselves as “neutral” than “introverted”.

There are three traits which comprise human personality: extraversion-introversion, neuroticism, and psychoticism. They are manifested in daily interpersonal communication. Social network analysis [

Sheman (2000) used social network analysis method to analyze the relationship among the students of a class [

Wen Yue Zhu, Jun Hui Gao (2014) use social network analysis to analyze the inner relationship within a designated class. They employ Cytoscape software to calculate parameters of each student in the network including Degree, EcCentricity, Closeness and Betweenness. By using social network analysis, they try to identify the most popular, least popular and most bizarre characteristics of the students. The results later proved to be consistent with the one given by the teacher. The paper further carried out a preliminary analysis on the mechanism of news spreading between the male and female students [

Questionnaires are used. Each student is asked to fill in their name on the questionnaire, the gender, the most contact with the contact name and three classmates least three students and a preliminary analysis (outward, inward, neutral) own character. Investigators would ensure the confidentiality of the survey results to the students in advance, in order to ensure that students fill out the authenticity of the information.

Data will be collected by sorting. Vertical columns in the order marked the students’ exposure to and contact with the most minimal of students to learn numbers in the corresponding horizontal.

Degree, degree vertices, the number refers to the vertex associated with the edges. In a directed graph, there InDegree and OutDegree. InDegree expressed here by other students that the most contact with the number, the greater the value InDegree, indicating that the greater the degree of students welcome. InDegree maximum students can be considered the best class in popularity. OutDegree, all students should all be 3.

BetweennessCentrality, referred Betweenness, betweenness centrality. Betweenness concept stems from the importance of social networks in the Individual. Simply put, Betweenness between a node represents the number of all the nodes on the shortest path of that node. Betweenness a good description of a network node may need to carry. Betweenness a node of the larger data packets passing through it, the more congestion means that it is easier to become a network bottleneck. Betweenness used to characterize the nodes in the network to influence the dissemination of information to measure the ability of a person as a medium. Consider a directed graph, where the calculated is BetweenessDir.

Tightness Closeness, vertex, metric to consider is the concept of the center, by the distance between the vertices of each figure to measure. Tightness vertex greater, indicating the apex living in the center of the network, the more important it in the network. Consider a directed graph, where the calculated and is In Closeness Out Closeness. Harmonic Closeness is a similar index and Closeness.

Eigenvector Centrality, referred Eigenvector, eigenvector centrality, a network node is a measure of importance. Each network node has a relative index value, which is based on the principle-the contribution of the high index node connected to a node node index lower than the contribution of high. Google’s PageRank is a variant of the eigenvector centrality measure. eigenvector those other actors with specific actors is linked into account the centrality of an actor and a measure of central indicators. For example, a friend, there are many links its three target actors, with another three friends which have no link actors compared to the former”s higher center of feature vectors.

see that, A, B two classes of students they think are neutral character of the majority, more than 50%. Followed by the outgoing, and finally introverted.

About the only definition of a network of community structure has not yet been widely recognized, more commonly used is based on the definition of the relative frequency of connections: a network of vertices can be divided into groups, the group connection between dense and sparse group connection.

In this paper, social network analysis is employed to investigate the relationship between the traits of the network of classmates and the personality traits of these students. First, questionnaires are distributed to these respondents. By asking the respondents to fill out their personal information and the fellow students with whom they have “the most frequent contact”, we get preliminary information about the network of the classmates within two classes in a local middle school and their personality traits data. Then, NetDraw software is employed to calculate multiple parameters of the class network. Mysql software is also used to process the data. At last; we found that the group of respondents who have the highest mean value of InDegree are students who have a neutral character instead of a extroverted one. Network parameters such as BetweenessDir, InCloseness, InEigenVector, InHarmonic Closeness are found out to be in consistent with the students’ personality traits. In addition, we conduct a community structural analysis on the network of “the most frequent contact” and a correlation analysis on the information of the community and the personality traits.
