领域本体与社群分类法结构中心性的比较研究

Comparative Study on Structural Centrality of Domain Ontology and Folksonomy

随着领域本体与社群分类法在知识组织研究领域中地位的日渐崛起，越来越多的学者对二者的结构属性展开了研究，一些研究中的模糊与分歧也随之产生。借助复杂网络分析的技术对领域本体网络与用户标签网络中各类中心性指标进行了计算与分析。研究得出，领域本体网络整体上具有较高的中心化程度，但节点的中心度在不同的中心性指标口径下会呈现出较大差异；社群分类法中的用户标签云在整体上内含较高的中心化程度，但在标签的个体层面上也保持了一定的自由化的特性。从结构中心性的视角澄清了模糊与分歧之处。

With the emergence of domain ontology and folksonomy in the field of knowledge organization, more and more scholars have carried out research on the structure property of the two, yielding some ambiguity and differences in their opinions. With complex network analysis technology, various centrality indexes are calculated and analyzed in domain ontology network and user tag network. It is drawn that domain ontology network as a whole has higher level of centralization, but the centrality of nodes show a large difference on different centrality indexes; User tag cloud of folksonomy has higher level of internal centralization as a whole, but the individual tags also keep the characteristics of liberalization. The vague and differences are clarified from the view of structural centrality.
