| 摘 要： | 以图书情报领域的学术信息为研究对象,选择有代表性的传统网络数据库、网络学术博客、网络学术论坛等信息平台为数据来源,采用共现分析方法构建基于不同信息源的知识图谱,包括单源、无权多源聚合、含权多源聚合、限定作者群的多源聚合等,通过对各种知识图谱进行比较分析探讨如何利用多源数据优化知识图谱的方法.研究表明,基于多源学术信息聚合的知识图谱能更好地反映知识类别的界限,知识构成更为紧密.

| Abstract: | This paper takes the academic information in the field of library and information science for example and chooses online database, academic blog and academic forum as data sources.It constructs knowledge maps based on different sources including single source map, unweighted aggregation of multi-source map, weighted aggregation of multi-source map and restrict-author-group multi-source map in the method of co-occurrence analysis. Through the comparative analysis ondifferent knowledge maps, it explores how to make use of multi-source data to optimize the method of map construction. Research shows that the knowledge map based on multi-source information aggregation can better reflect the boundaries of knowledge and make the knowledge structure more close. |
