The retrieval quality of literature evidence is the basic guarantee of high-level evidence-based research. Based on the analysis of the initial problem of document evidence retrieval in the field of evidence-based research, this paper draws on the reasonable components of traditional recall and precision indicators and overcomes their shortcomings, puts forward new literature evidence retrieval quality assessment indicators such as saturation, redundancy and sensitivity, and introduces the indicators of the quality of measurement tools such as reliability and validity into this field. Furthermore, this paper shed light on the future trend of scientific evaluation of literature evidence retrieval quality in evidence-based social science research. The literature quality evaluation index involved in this paper lays a foundation for the follow-up empirical research.
