Taking the methods as the entry point,this article firstly constructs information analysis method glossary,then analyzes the hierarchy,the classification and the application perspectives of information analysis methods. The paper summarizes the method hierarchy of"the theoretical methods guiding thinking logic,the integrated methods integrating research process,the operational methods implementing task solving,and the computational methods realizing the measurement". This paper manifests the method-guided ideology of information analysis,in order to reveals the application law of information analysis methods in data processing and task solving.
