The Impact

With the great development of mobile services, the Quality of Services (QoS) becomes an essential factor to meet end users’ personalized requirement on the nonfunctional performance of mobile services. However, most of the QoS values in real cases are unattainable because a service user would only invoke some specific mobile services. Therefore, how to predict the missing QoS values and recommend high-quality services to end users becomes a significant challenge in mobile service recommendation research. Previous QoS prediction researches demonstrate that the nonfunctional performance of mobile services is closely related to users’ location information. However, most location-aware QoS prediction methods ignore the premise that the obtainable QoS values observed by different users in same location region would probably be untrustworthy, which will lead to inaccurate and unreliable prediction results. To make credible location-aware QoS prediction, we propose a hybrid matrix factorization method integrated location and reputation information (LRMF) to predict the unattainable QoS values. Our approach firstly cluster users into different locational region based on their geographical distribution, and then we compute users’ reputation to identify untrustworthy users in every locational region. Finally, the unknown QoS values can be predicted by integrating locational cluster information and users’ reputation into a hybrid matrix factorization model. Comprehensive experiments are conducted on a public QoS dataset which contains sufficient real-world service invocation records. The evaluation results indicate that our LRMF method can effectively reduce the impact of unreliable users on QoS prediction and make credible mobile service recommendation.

AbstractThe purpose of this study is to assess the technical (output) and functional (process) quality of mobile services, as well as the role of corporate image as a mediator between technical/functional quality perceptions and overall quality assessment of mobile services. Grönroos’s service quality model is used as the conceptual base of the study. Technical quality was operationalized through two sub-dimensions: baseline network quality and augmented technical quality. The SERVPERF framework was used in the operationalization of the functional quality. A quantitative survey was conducted with (n = 414) customers of the telecommunication operator in B&H. The results suggest that corporate image mediates the effects of (1) two functional quality dimensions (tangibles and assurance) and (2) both technical quality dimensions on the overall service quality assessment. The core technical quality dimension (network) is also directly related to overall service quality perception. A discussion of the results and their implications for theory and practice is then presented.
