研究领域的主题发展趋势分析方法研究——基于多重共现的视角

Studies on the Analysis Method of Subject Development Trend in Research Fields: From the Perspective of Multiple Co-occurrence

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。

This paper proposes the model for analyzing the development trend of the subjects in research fields from the per-spective of multiple co-occurrence. The paper improves the Morris＇ cross-mapping technology and makes it suitable for the visual a- nalysis of the multiple co-occurrence of the subject development trend in research fields. The research field of competitive intelli- gence is selected for empirical study. By analyzing the 2 multiple co-occurrence relations in this research field, namely, year-key- word-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.
