基于信息检索的需求跟踪方法综述

A SURVEY OF REQUIREMENT TRACKING METHOD BASED ON INFORMATION RETRIEVAL

需求跟踪作为软件过程管理中的一个重要环节,在保障系统质量、应对需求变更方面发挥着重要作用。利用需求跟踪,软件工程师可以发现制品之间的依赖关系、评估需求覆盖率和计算需求变更的影响。随着软件项目的日益复杂和软件制品数量的增加,跟踪关系的自动恢复和维护日益受到业界关注。近年来,人们对于基于信息检索的需求跟踪自动化技术做了大量研究。针对基于信息检索的需求跟踪技术进行综述,从技术改进、支撑工具和度量指标三个方面进行了深入分析。在此基础上,对其发展趋势和有待深入的研究点进行了展望。

Requirement tracking,as an important part of software process management,plays an important role in ensuring system quality and responding to requirement change. Using requirement tracking,software engineers can find dependencies among products,assessing demand coverage,and calculating the impact of changes in requirements. With the increasing complexity of software projects and the increase in the number of software products,the automatic recovery and maintenance of tracking relations has attracted more and more attention. In recent years,people have done a lot of research on requirement tracking automation technology based on information retrieval. We summarize the requirement tracking technology based on information retrieval, and carry out in-depth analysis from three aspects： technical improvement,support tools and metrics. On this basis,we look forward to its development trend and further research.
