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。 The core of implementing common word analysis lies in setting the window of co-occurrence analysis. Under the premise of marking the content structure of documents, the dynamic co-word method has three main features: multi-stage text segmentation, phrase-weighted phrase frequency and dynamically adjusted co-occurrence statistical range. Collective results more closely reflect the thematic links in the corpus and provide intelligence researchers with higher-quality analyzes.
