| 摘 要： | 实施共词分析的核心在于设定共现分析的窗口。在标记文献内容结构的前提下，动态共词方法具有三个主要特征：多阶段的文本切分、按位置加权的短语频次、动态调整的共现统计范围。共同结果能更贴切地反映文献集内的主题关联，为情报研究人员提供质量更高的分析结果。

| Abstract: | The definition of co-occurrence range is a key parameter of co-word method. With usefully analyzed text structure, the brand new dynamic co-word method show 3 main features when deals with English text: multi-stage segmentation, phrase frequency weighted by position, dynamically adjusted co-occurrence range. It can reveal the relationship of themes appositely and support the information experts with higher quality results. |
