语义通信系统的性能度量指标分析

Analysis of Performance Metrics of Semantic Communication Systems

语义通信系统是目前通信领域的研究热点,但是该领域尚未建立起成熟的评价体系,导致不同性能度量指标下设计的语义通信系统的性能也各不相同。文中主要针对语义通信系统,介绍了基于精确率的性能度量指标、基于召回率的性能度量指标、基于精确率与召回率相结合的性能度量指标以及基于词向量空间模型的性能度量指标;并详细阐述了语义通信中各种性能度量指标提出的背景、意义、主要算法思想和适用范围,对比分析了每一种性能度量指标间的差异和优缺点。最后,总结了现阶段语义通信性能度量指标面临的问题,并展望了语义通信系统中性能度量指标研究的未来发展方向。

Semantic communication system is currently a hot research topic in the communication field,but a mature evaluation system has not been established in this field,which leads to the different performance of semantic communication systems designed under different performance metrics.This paper mainly focuses on semantic communication systems,introducing perfor-mance metrics based on precision,performance metrics based on recall,performance metrics based on the combination of precision and recall,and performance metrics based on word vector space models.It also elaborates on the background,significance,main algorithm ideas,and scope of application of various performance metrics in semantic communication,and analyzes and compares the differences,advantages and disadvantages of each performance metric.Finally,it summarizes the problems faced by semantic communication performance metrics at this stage,and points out the future development direction of performance metrics research in semantic communication system.
