One solution to the problem is to use distributed web service search system composed of domain specific sub service discoverers. Using ontology is the most common practice to specify domain knowledge. However, an important problem at this point is the lack of semantic annotation for currently available web services. For this reason, there is a strong need for a mechanism for semantic annotation of unannotated services. In this work, we propose a web service semantic annotation method that uses lexicon-based alignment. Lexicon-based alignment considers the different senses of the words, and hence it can find the association between the service and the ontology more accurately than previous alignment techniques.","PeriodicalId":429726,"journal":{"name":"2011 IEEE World Congress on Services","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114777333","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}

Virtual Rank proposes a solution that determines when to migrate virtual machines, and where to migrate. Most of the traditional load balancing techniques are based on threshold, whereas Virtual Rank predicts load tendency in the upcoming time slots. It ensures a small transient spike which does not trigger needless virtual machine(VM) migration. After triggering migration, the technique selects the potential migration target applying the Markov stochastic process. Finally the weighted probability method is applied to confirm the final migration target. It resolves the accumulation conflicts, as well as increases the stability. We implement our techniques in virtual computing environment iVic and conduct a detailed evaluation using a mix of CPU, network applications. We demonstrate that in different scale virtual network, Virtual Rank achieves better load balancing performance, compared with traditional methods.","PeriodicalId":429726,"journal":{"name":"2011 IEEE World Congress on Services","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129099588","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}

One of the key technologies for achieving this will undoubtedly be cloud computing which opens up many new opportunities for streamlining the way computing services are delivered and used. Several research projects have therefore recently started to examine ways of improving the efficiency of cloud computing infrastructures and of understanding the energy efficiency of computing algorithms. However, to date these have mainly focused on increasing the efficiency of cloud computing services at the relatively low \"platform\" and \"infrastructure\" levels of abstraction at which they are typically offered today. In this paper we argue that to maximize the environmental benefits of cloud computing, both from the demand as well as the supply point of view, it is necessary to raise the level of abstraction at which cloud services are delivered and consumed. To this end, we introduce the vision of \"Modelling as a Service (MaaS)\" and explain how it provides an essential foundation for reducing the environmental impact of computing services.","PeriodicalId":429726,"journal":{"name":"2011 IEEE World Congress on Services","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130076526","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}
