| 本文采集了豆瓣网上2,534本图书情报学科领域的图书在四个时间点的标签数据构建标签共现网络,利用标签分析和确定概念的序化和聚类(知识结构),揭示用户在图书标注环境下的认知特征。统计分析发现:标签共现网络的网络结构具有幂律特征,并服从稠密化幂律分布,适用于研究用户认知状态动态演化；标签共现网络为非均匀网络,度数较高的节点词汇处于核心位置,是最为基本的概念,而中介中心性较高的节点词汇反映概念在知识结构中的控制能力强,对标签共现影响较大,对网络的流动性至关重要,这些词汇的共同点在于相对概念比较宽泛,说明用户会优先选择易于理解的词汇进行标注和认知。图4。表4。参考文献25。 |
| 英文摘要: |
| This paper collects 2,534 books in LIS and their tags data at four timing points at www.douban.com to construct the co-occurrence network of tags, analyze and determine the ordering and clustering of concepts(knowledge structure) by use of tags, and reveal the cognitive characteristics of users in the context of tagging book.This paper finds that, the structure of the co-occurrence network of tags is characterized by “power law” and obeys densification power law distribution, which is appropriate for studying the dynamic evolution of users' cognitive state; the co-occurrence network of tags is a inhomogeneous network, in which node terms with higher degree are at the core position as the most basic concepts, while node terms with higher betweenness centrality reflect the ability of the concepts in controlling knowledge structure, have greater influence on co-occurrence of tags, and are crucial to network mobility, which have relatively broad concept in common and explain that users would take priority to choose easily-understood terms to tag and recognize.4figs.4tabs.25refs. |
