摘　　要：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。As a kind of knowledge organization model, Folksonomy is applied in many libraries and literature databases, and the hierarchy behind flat discrete external appearance has been the focus of library and information academic community. With the theory of complex networks, domain knowledge networks are constructed based on co-occurrence relationship between tags, local hierarchy of tags are divided according to network path length, and the evolution process of local hierarchy is tracked and analyzed dynamically from the perspective of time series. The results show that the local hierarchies of tags change continuously with the development of domain knowledge; and tags can promote or demote along time shaft; the structural relationships within the tags local hierarchies are more complex than traditional knowledge organization system. These conclusions make useful exploration for the reveal of patterns and rules in evolution of tags local hierarchies.
