Folksonomy知识组织模式在众多的图书馆和文献数据库中被应用,其平层离散的外在表象背后的层级结构一直是图书情报学界关注的重点。借助复杂网络的理论,基于标签之间的共现关系构建领域知识网络,依据网络路径长度划分标签局部层级,从时间序列的角度对标签局部层级结构的演化进程进行了动态跟踪与剖析。研究结果显示,标签的局部层级结构随着领域知识的发展不断地演化变迁,并伴随有标签晋升、降级的情况,层级结构内部的结构关系比传统知识组织体系更为复杂多样,这些结论为揭示标签局部层级演化的模式与规律做出了探索和尝试。
The Folksonomy model of knowledge organization has been applied in many libraries and document databases. The hierarchical structure behind the discrete external appearance of Folksonomy has always been the focus of the LIS field. With the help of the theory of complex networks, a domain knowledge network is constructed based on the co-occurrence relations among tags. The local level of tags is divided according to the length of the network path, and the evolution of the local hierarchical structure of the tags is dynamically tracked and analyzed from the perspective of time series. The results show that the local hierarchical structure of labels changes and evolves with the development of domain knowledge, accompanied by the promotion and demotion of labels. The structural relations within the hierarchical structure are more complex and diverse than that of traditional knowledge organization system. These conclusions are revealed Label local level evolution patterns and laws made to explore and try.
