Research Of Nodes Relationships In SNS Networks

With the improvement of Internet application coverage and the rapid development of Web 2.0 technologies, social networks have already become one important basic application for Internet users. Diversity web applications brought by social networks are changing the habits of individuals to use internet, and meanwhile have played positive roles on the development of Internet.During the process of social network services, SNS (Social Networking Services) as one of new things has been produced.

Individuals can find other needed ones through familiar ones in the social service networks and provide more scientific and reasonable management for interpersonal resources. SNS networks are attracting more and more Internet users because of its efficient and convenient services, which has great prospects for development.Social networks include a series of network members and the relationships which link these members together. It fully reflects the internal needs of individual interactions. Of which: network members can be individuals and also can be the integrated departments or organizations which can form networks through the interactions between them. The network of relationships is more complete in the systems, individuals can obtain more information and helps.Through the analysis of individual relationships, it can reflect the actual social situations of individuals, meantime dig out valuable information which brings some convenience for work and life.This study mainly does the following things based on the analysis of domestic and international status:1. Proposes a model for analysis the relationship of network nodes. This model abstracts the individual member of network into specific network node and the links between nodes into lines, as well as uses the distance from the center node to stand for their intimacy of relationships.2. Node relationships can be divided into different types according to different criterias bases on the abstracted network architecture framework. The methods: 1) In accordance with the reasons for nodes formation: blood ties, geopolitical relations, friendship relations, industry margin relationships; 2) In according to the forming process of nodes relations: blood ties, geographic relationships, learning relationships, industry margin relationships, Emotional relationship; 3) According to the formed orders of nodes relations: congenital relations, acquired relations.3. Analyzes the 12 factors which have impacts on the nodes intimacy and gives out some curves for their intimacy based on the specific forms of relationship.4. Gets the matrix and predicts the node pattern of relationships by through analysis of on-line interactions between network nodes. The multivariate methods which are used in the study can not only calculate the intimacy between nodes, but also can be proved by concrete examples.The results show that: to adopt the model and use the data obtained by questionnaires to calculate the intimacy of nodes is possible through the analysis of nodes online interactive behaviors, which has the space for further improvement and development.
