Folksonomy知识组织模式中领域知识动态演化规律研究

Dynamic Evolution Rules of Domain Knowledge in Folksonomy Knowledge Organization Mode

Folksonomy知识组织模式在众多的图书馆和文献数据库中被应用,其特有的演化发展规律也一直是图书情报学界关注的重点。文章借助复杂网络理论,基于标签之间的共现关系构建了领域知识网络。从领域知识网络的基本属性、中心性和群聚性三个方面,对领域知识的演化过程进行了动态跟踪与时序分析。研究结果显示,Folksonomy模式中领域知识网络逐渐向小世界网络演化;领域知识的中心性并非完全协同一致;领域知识的群聚性与标签关联关系相关。

As a kind of knowledge organization model, folksonomy is applied in many libraries and literature databases and the evolution rules of folksonomy are one of the focuses of library and information academic community. With the theory of complex networks, this article constructed domain knowledge networks based on co-occurrence relationship between tags. From the basic properties, centrality and aggregation of domain knowledge network, the evolution process of domain knowledge was tracked and time-series analyzed. The results show that domain knowledge network evolves to small-world network; Centralities of domain knowledge are not entirely concerted; Aggregations of domain knowledge are associated with the relationships of tags.
