摘要 在情报分析结果中经常要表达层次的结构,可是随着数据量和复杂性的增大,传统的显示方式有极大的局限性。TreeMap是信息可视化技术中用于显示树型结构的重要技术,虽然已有不少成功案例,但到目前为止并未见用于情报分析。笔者在开源算法的基础上架构了一个利用TreeMap的处理工具。为验证工具的有效性,运用它对"竞争情报"相关论文在期刊上的发表情况进行了分析。 It＇s common for information analysis results to be displayed in hierarchical structure. However, with the increase of the volume and complexity of the data, the traditional display type has great limitations. TreeMap is an important technology to display the tree structure in information visualization technology. Although there are many successful application cases, up to now it has not been used in information analysis. Based on the open source algorithm, this paper devises a processing tool which utilizes TreeMap. To test the validity of the tool, the paper uses it to analyze the publication of papers about competitive intelligence in joumals.
