文摘

Propose a collaborative QoS prediction approach via time series analysis. Use cloud model theory to model time series feature of multi-valued QoS evaluations. Propose a vector comparison method to measure similarity between QoS cloud models. Employ the FAHP method to identify the weight of every time period objectively. Verify the effectiveness of the proposed approach based on a real-world datasets.
