| 1 | A Novel Approach for QoS Prediction Based on Bayesian Combinational Model显示文摘As an important factor in evaluating service,QoS(Quality of Service) has drawn more and more concerns with the rapid increasing of Web services. However,due to the great volatility of services in Mobile Internet environments,such as internet of vehicles,Web services often do not work as announced and thus cause unacceptable problems. QoS prediction can avoid failure before it takes place,which is considered a more effective way to assure quality. However,Current QoS prediction approaches neither consider the highly dynamic of Web services,nor maintain good prediction performance all the time. Consequently we propose a novel Bayesian combinational model to predict QoS by continuously adjusting credit values of the basic models so as to keep good prediction accuracy. QoS attributes such as response time,throughput and reliability are used to validate the proposed model. Experimental results show that the model can provide stable prediction results in Mobile Internet environments. | Pengcheng Zhang Yingtao Sun Hareton Leung Meijun Xu Wenrui Li | 2016 | China Communications2016，13，11： | 3 |

| 9 | A new method to encode calling contexts with recursions显示文摘Calling context encoding(CCE) uses some integers to represent the current context of any execution point, and is valuable in a wide range of applications. Existing studies already ensure accurate results of CCE,but they use stack to store the encoding when recursive calls happen. This may cost much for cyclic call graphs with deep recursive calls. This paper presents a novel approach(called RCCE) to address this problem. With a modified strategy for encoding, it requires less frequent access of the stack and gives more succinct representation of contexts on deep recursion. Experimental results show that compared to Precise Calling Context Encoding,RCCE is more practical and efficient on calling contexts with recursions. | Lulu WANG Bixin LI Hareton LEUNG | 2016 | Science China(Information Sciences)2016，59，5： | 0 |
| 10 | Profiling selected paths with loops显示文摘Path profiling records the frequency of each path in an executed program.To accomplish profiling,probes are instrumented in the program and executed as the program runs.So,the number of probes has a significant impact on the efficiency of a profiling technique.By profiling only the interesting paths,existing techniques try to improve the profiling efficiency by reducing the number of probes and optimize path encodings for efficient storage.However,they lack accuracy,waste time on running uninteresting paths,and can mainly deal with acyclic paths.In this article,a novel technique called Profiling Selected Paths(PSP)is introduced to profile selected paths,which enables custom selection for both acyclic and cyclic paths and increases the execution efficiency by early termination on uninteresting paths.Theoretical analysis and experimental evaluation indicate that PSP performs better than existing techniques. | LI BiXin WANG LuLu LEUNG Hareton | 2014 | Science China(Information Sciences)2014，57，7： | 0 |
