提出了一种基于知识网络的专家知识表示方法,这种方法利用维基百科作为背景知识,根据专家的科研成果和相关内容,自动构建专家个人的知识网络。在此基础上,分别从专家知识的广度和深度、研究兴趣划分、核心知识探测和知识稀缺性这些角度对专家知识网络进行了度量。最后,在一个真实科研组织中构建了专家的知识网络,并进行了度量和分析,验证了本文提出方法的有效性。
An expert knowledge representation method based on knowledge network is proposed. This method uses Wikipedia as the background knowledge and automatically builds an expert knowledge network according to the experts’ research achievements and relevant contents. On this basis, we measure the expert knowledge network from the aspects of the breadth and depth of expert knowledge, the division of research interest, the detection of core knowledge and the scarcity of knowledge. Finally, a knowledge network of experts was constructed in a real research organization, and the measurement and analysis were conducted to verify the effectiveness of the proposed method.
