Service evaluation is an important way to promote service construction and quality optimization. University library context-aware service evaluation includes service results evaluation and process evaluation. Owing to the complicate and dynamic characteristics of context-aware service,it is necessary to construct multidimensional and systematic service evaluation index system which includes service environment,service resources,service interaction and service effect. Combining qualitative and quantitative analysis,synthesizing subjective and objective evaluation,and carrying out comprehensive evaluation from the perspectives of librarian and user,the paper can provide references for improving service quality by identifying the problems in service through evaluation.
