| 摘 要： | 基于多重共现的视角,提出可适用于研究领域主题发展趋势的分析模型,并对Morris的交叉图技术进行改进,使其适用于研究领域主题发展趋势的多重共现可视化分析,选取了竞争情报研究领域作为实证分析。通过分析该研究领域中的年份—关键词—机构、年份—关键词—发表期刊这两个多重共现关系,发现竞争情报研究领域中研究主题在年份、研究机构、发表期刊之间的发展趋势与变化情况。 |
| 关 键 词： | 研究领域 主题分析 多重共现 方法研究 |

| Abstract: | This paper proposes the model for analyzing the development trend of the subjects in research fields from the perspective of multiple co-occurrence.The paper improves the Morris’ cross-mapping technology and makes it suitable for the visual analysis of the multiple co-occurrence of the subject development trend in research fields.The research field of competitive intelligence is selected for empirical study.By analyzing the 2 multiple co-occurrence relations in this research field,namely,year-keyword-institution and year-keyword-published journal,the paper finds out the development trend and change of the research subject among years,research institutions and published journals in the research field of competitive intelligence. |
| Keywords: | research field subject analysis multiple co-occurrence method study |
