摘要
[目的/意义]要做好反恐情报预警工作,就要做好反恐情报的收集、整理和分析。[方法/过程]以反恐情报文献为研究对象,应用可视化分析和统计学方法,对不同的统计标引主题词在聚类分析和关联分析中的应用效果进行研究。[结果/结论]结果显示,将频次在50次以上关键词作为重点标引词,可取得较好的分类效果。但是从研究反恐情报的主要领域来看,取全部关键词作为统计标引词会取得更好的效果。
[Purpose/significance]To do a good job of counter-terrorism pre-warning intelligence,it is needed to strengthen collection,collation and analysis of articles on counter-terrorism intelligence. [Method/process]The paper takes articles on counter-terrorism intelligence as research objet,studies the application effect of different statistical subject headings in cluster analysis and correlation analysis by using visualized analysis and statistical methods. [Result/conclusion]The results show that using top 50 frequency keywords as the key indexing words can obtain good clustering effect,but using all keywords of statistical terms can get better clustering effect form angle of main fields of counter-terrorism intelligence.
