摘　　要：【目的】从单篇文献入手,在其引文网络中追踪研究主题的来源与走向。【方法】首先,利用领域本体识别单篇文献中的主题;其次,筛选与主题相关的二级参考文献、参考文献、引证文献、二级引证文献,构建面向单篇文献的引文网络;然后,对引文网络进行增量聚类处理,形成主题的来源与走向演化图。【结果】充分揭示文献主题来源或走向中继承、分化、合并的结构变化及各阶段的内容变化。【局限】引文网络构建时文献的筛选条件有待深入研究;主题识别未考虑领域本体中词汇收录不完备问题。【结论】本研究对单篇文献主题的来源与走向进行有效的追踪,能够较好地揭示文献主题的来龙去脉。[Objective] To track topic sources and trends for a high-impact paper from its citation network. [Methods] Firstly, topics are detected for each paper by domain Ontology. Secondly, a citation network towards a single paper＇s topic is constructed. The nodes of the network are selected from second level cited papers, cited papers, citing papers and second level citing papers according to their contents. Thirdly, incremental cluster is applied for mining topic sources and trends from the network constructed before, the noisy sources or trends are filtered, and evolution paths of topics are formed. [Results] The structure changes and content changes of topic sources and trends are fully revealed. [Limitations] The screening conditions for the construction of citation network need to be further studied. Besides, completeness of the domain Ontology is not considered. [Conclusions] This study tracks topic sources and trends for single paper effectively, and helps reveal origin and development of the topics.
