[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.
