摘要

以引文上下文为研究对象，探讨来自于引文上下文、目标文献摘要以及目标文献自标医学主题词（下称主题词）三者间的符合程度，定量分析引文上下文在表征目标文献内容特征时的作用。以被Circulation杂志高频引证的5篇研究类论文作为目标文献，提取其施引文献的全部引文上下文，并对其进行分词及主题词匹配；将其结果与目标文献摘要提取的主题词以及文献自标的主题词进行两两比较。结果表明，引文上下文与目标文献摘要具有较高的符合度，而且在表征被引文献内容特征的效果上明显具有优势。

Abstract

In order to investigate the relationships among citation context, the abstract and the cited target papers, and explore quantitatively the effect of the citation contexts in revealing the subject features of the cited target papers, five highly cited target papers by Circulation were screened. The citation contexts were extracted from all citing papers and the medical subject headings (MeSH terms) were matched. The pairwise comparison was performed among MeSH terms extracted from citation context, abstracts and indexed by the target paper itself. The result shows that the MeSH terms matched from the citation context is in highly conformity with that from the abstract of the target paper. The citation context can express the subject features of the target paper even better than the abstract.

Key words： citation context; information value; information analysis; text mining; information extraction
