Requirements traceability-that is the ability to relate requirements specifications with other artifacts created in the development life-cycle of a software system-has widely and long been recognized as a significant factor for efficient software project management and software systemsquality. However, these important tasks are all handwork and what helpful is only version tracing management nowadays. In this paper a methodology based on semantic model is presented. The process from requirements acquisition to editing of SRS into phases was segregated, then semantic elements and semantic links of every phase were found out. Finally, the problem of transformation of semantic models is discussed.
