基于随机游走策略的专家关系网络构建

专家关系组织是专家关系网络构建的核心。提出了一种基于随机游走策略的专家关系网络构建方法,该方法首先提取专家实体及关系,获得专家之间朋友关系、指导关系及同事关系的简单无向图,利用图中专家节点连接关系,构建专家关系矩阵,然后借助随机游走策略思想,将若干表征专家关系的简单无向图进行有机组合,从而构建出复杂专家关系网络。实验结果验证了该方法的有效性。

Construction of expert relationship network based on random walk strategy

Organizing expert relationship is the core of constructing expert relationship network. A method was proposed to build an expert relationship network based on random walk strategy. Firstly, on the basis of the extracted expert entities and their relationships, the method gets a friend relationship, or a guidance relationship or a colleague relationship between two expert entities to form a simple undirected graph. From the relationships between expert nodes in these graphs, an expert relationship matrix was built. Then according to random walk strategy thought, it is made an organic combination of these simple undirected graphs which characterize expert relationships to construct a complex network of expert relationships. The experimental results show that the proposed method to construct an expert relationship network based on random walk strategy is effective.
