The classification of the automatic summarization contributed to the construction of automatic summarization and the development of automatic summarization technology is based on the features of automatic summarization. This paper also outlines the historical development of automatic smnmarization and describes the current research methodology, classifies them into three categories by existing technologies and methods, respectively, discusses the basic character and research methods of the three categories, and analyzes the merits and defects as well. This paper emphasizes the text structure-based method, and introduces several research directions and their localization and trend. In the end, the existing problem and the developing trend of automatic summarization technology are discussed.
