Cloud Service Selection Based on Contextual Subjective Assessment and Objective Assessment

This paper proposes a novel cloud service selection model based on the comparison and aggregation of contextual subjective assessment and objective assessment of cloud services. In this model, objective assessment provided by some professional testing parties is used as a benchmark to dynamically filter out biased subjective assessment extracted from cloud user feedback according to assessment context similarity. Through this model, the overall quality of cloud services can be effectively reflected with less subjective bias for potential cloud consumers.
