摘要
程序理解是实现对软件系统自动分析和理解的技术.作为程序理解中必不可少的环节,信息抽取是实现程序理解的第一步.信息抽取机制的优劣直接影响着抽取信息的效率.通过对比较典型的抽取机制和工具的分析研究,阐述了现有程序理解系统存在的问题,提出相应的改进措施,设计出了一种改进型信息抽取系统.
Program understanding is a kind of technology that can achieve automatic analysis and understanding of software system. As an essential sector, information extraction is the first step in program understanding. The quality of the information extraction mechanisms will influence the efficiency of information extraction directly. By comparing typical extraction mechanisms and tools, the problems in existing program understanding is discussed. An improved method is provided and a new information extraction system is designed.
