In the context of on-demand SBA execution, suitable services are selected and integrated at runtime to meet different non-functional requirements (such as price and execution time). In such dynamic and distributed environment, an important issue is to guarantee the end-to-end Quality of Service (QoS). As a consequence, SBA provider is required to monitor each running SBA instance, analyze its runtime execution states, then identify proper adaptation plans if necessary, and finally apply the relative countermeasures. One of the main challenges is to accurately trigger the adaptation process as early as possible. In this paper, we present a two-phase decision approach that can accurately analyze the adaptation needs for on-demand SBA execution model. Our approach is based on the online prediction techniques: an adaptation decision is determined by predicting an upcoming end-to-end QoS degradation through two-phase evaluations. Firstly, the end-to-end QoS is estimated at runtime based on monitoring techniques; if a QoS degradation is tent to happen, in the second phase, both static and adaptive strategies are introduced to assess whether it is the best timing to draw the final adaptation decision. Our approach is evaluated and validated by a series of realistic simulations.","PeriodicalId":178841,"journal":{"name":"2012 IEEE Ninth International Conference on Services Computing","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122449167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A common hypothesis of previous research is that the QoS information to the current user is supposed all known and accurate. However, the real case is that there are many missing QoS values in history records. To avoid the expensive and costly Web services invocations, this paper proposes an extended Matrix Factorization (EMF) framework with relational regularization to make missing QoS values prediction. We first elaborate the Matrix Factorization (MF) model from a general perspective. To collect the wisdom of crowds precisely, we employ different similarity measurements on user side and service side to identify neighborhood. And then we systematically design two novel relational regularization terms inside a neighborhood. Finally we combine both terms into a unified MF framework to predict the missing QoS values. To validate our methods, experiments on real Web services data are conducted. The empirical analysis shows that our approaches outperform other state-of-the-art methods in QoS prediction accuracy.","PeriodicalId":178841,"journal":{"name":"2012 IEEE Ninth International Conference on Services Computing","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123924884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
