摘要

摘要: 在社交网络的演化和发展过程中，用户之间关系的建立受到多种因素的共同作用。该文通过对社交网络中用户属性以及用户关系数据进行分析，旨在发现影响用户关系建立的关键因素。首先，针对用户关系建立的复杂驱动因素，分别从个人兴趣、好友关系、社团驱动3个方面提取影响用户关系建立的因素并定义相应的影响因子函数。其次，针对多种影响因素难以量化以及权值分配不确定等问题，以最大熵原理为基础构建用户关系分析模型，该模型在选择特征时具有不需要依赖于特征之间的关联性等特点，并能够量化各个因素对用户关系建立的驱动强度。从而挖掘影响链接建立的关键因素，分析用户关系发展态势。实验表明，该模型不仅能够量化各因素对链接建立的驱动强度，发现关键影响因素，而且可以对用户关系进行有效预测。

Abstract: Within the evolution and development of social networks, the establishment of relationships among the users is affected by various factors. By analyzing user behavior data and relationship data in social network, this study tries to detect the key factors that affect the formation of relationship among users. Firstly, considering the complex driving factors for the user relationship establishment, the factors are extracted and the impact factor functions are defined from personal attributes, friendships and community driving. Secondly, in order to quantify driving factors and assign weight, a user relationship analysis model based on the principle of maximum entropy is proposed. The model is, when choosing features, characterized by its independence from?the association among features, and can also quantify the strength of various factors that drive users to establish relationship. Furthermore, the key factors that affect the user relationship can be detected and the development trend of user relationship can be analyzed. Experimental results reveal that the proposal model can not only quantify the strength of each factor that drives relationship establishment, it can also predict the user relationship effectively.
