Abstract: In recent years, cooperation on the Web such as open source community etc., which has social network character, gets rapid development. Therefore, it is necessary to acquire models and techniques that considering social and cooperation character. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and the cooperation relationship between collaborators. Based on the definition of three behaviors, this paper gives the method of measuring the contact intensity. And based on the definition of cooperative behavior, this paper gives the method of measuring the cooperation intensity. By using the open source community data from www.codeplex.com, the paper tests and verifies the feasibility and effectiveness of the method.

Key words: social network, contact relationship, cooperation relationship, work similarity, cooperation recommendation

摘要： 近几年，开源社区等具有社会网络性质的网络协作得到了较快发展，有必要获取一种考虑社会关系和协作特性的模型和技术，从而进一步推进社会网络协作的开展。从社会网络理论出发抽象出协作网络的拓扑结构，提出了一种综合考虑协作者之间的联系关系和合作关系的协作者社会网络模型构造方法。在定义三种联系行为的基础上，给出了度量联系关系强度的方法。在界定合作行为基础上，给出了度量合作关系强度的方法。通过使用开源社区www.codeplex.com的数据进行实验，证明了模型和方法的有效性。
