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。 Based on the multiple co-occurrence perspective, this paper proposes an analysis model that can be applied to the development trend of the research field, and improves Morris’s crossover graph technology to make it suitable for multiple co-occurrence visualization analysis of the development trend of the research field, selecting competitive intelligence Research area as an empirical analysis. By analyzing two multiple co-occurrence relations such as year-keyword-agency, year-keyword-publishing journal in the field of research, we find the development trend of research topic in year, research institute and published periodical in competitive intelligence research field And changes.
