对研究者发文序列的研究不仅可帮助了解领域研究现状,而且对于会议评级、热点预测分析等都有重要的意义.通过对研究者出版序列中的会议进行分析,提取会议序列并进行聚类,有助于发现领域相关性,理解领域发展演化.该文针对会议序列提取中直接考虑前后顺序所存在的不准确,提出了根据时间片相关的会议序列提取方法,以提高会议聚类的准确性.通过真实数据集上的定量和定性实验证明了该方法的有效性,并对结果进行了实例分析.
對研究者髮文序列的研究不僅可幫助瞭解領域研究現狀,而且對于會議評級、熱點預測分析等都有重要的意義.通過對研究者齣版序列中的會議進行分析,提取會議序列併進行聚類,有助于髮現領域相關性,理解領域髮展縯化.該文針對會議序列提取中直接攷慮前後順序所存在的不準確,提齣瞭根據時間片相關的會議序列提取方法,以提高會議聚類的準確性.通過真實數據集上的定量和定性實驗證明瞭該方法的有效性,併對結果進行瞭實例分析.

Researchers' publication sequence contain some important information which can be utilized to discover the research areas trend, reflect the relative ranking of academic conferences, and indicate the hot research topics. A systematic method is proposed to discover the knowledge hidden in the publication sequences to identify the connection between different research disciplines and to understand the evolution of the research area. More specifically, for the inaccuracy of the consecutive conferences sequences extracted from publication sequences, a new method is presented to extract sequences based on time slice information, so that the clustering accuracy can be improved. The quantitative and qualitative analysis of experiments in real datasets has been provided to illustrate the effectiveness of proposed method.
