Efficient and adaptive discovery techniques of Web Services handling large data sets

Techniques to support Web Service selection and consumption with QoS characteristics

“…In other words, QoS negotiation and monitoring are necessary in order for both users and providers being satisfied (Menasce´, 2002). One such paradigm can be found in Makris et al (2006) where QoS negotiation and adaptive WS selection is performed.…”

Client-side selection of replicated web services: An empirical assessment

“…Zhou et al, 2004;Tian et al, 2004;Yu and Lin, 2005a;Serhani et al, 2005), and also to allow client applications to dynamically collect QoS service information of interest and then select the best service available (amongst a set of functionally equivalent services), based on a variety of user-defined QoS constraints (e.g. Ouzzani and Bouguettaya, 2004;Liu et al, 2004;Tian et al, 2004;Zhuge and Liu, 2004;Hu et al, 2005;Serhani et al, 2005;Yu et al, 2005b;Makris et al, 2006). From a service selection perspective, those solutions have the added benefit that, in principle, they can select services based on any desired QoS criteria (Ran, 2003).…”

“…The study of efficient selection strategies for accessing replicated or functionally equivalent web services has attracted a growing attention from the web services research community in recent years (e.g. Padovitz et al, 2003;Keidl and Kemper, 2004;Costa et al, 2004;Tian et al, 2004;Liu et al, 2004;Yu and Lin, 2005a;Hu et al, 2005;Makris et al, 2006;Salas et al, 2006). However, most of the service selection solutions proposed thus far suffer from one or more of the following limitations: they require modifications to the standard SOC model, often by extending the existing SOC technologies, such as WSDL and UDDI, with novel mechanisms to support publication and discovery of QoS service information (e.g.…”

“…However, most of the service selection solutions proposed thus far suffer from one or more of the following limitations: they require modifications to the standard SOC model, often by extending the existing SOC technologies, such as WSDL and UDDI, with novel mechanisms to support publication and discovery of QoS service information (e.g. Tian et al, 2004;Liu et al, 2004;Yu and Lin, 2005a;Hu et al, 2005;Makris et al, 2006). This means that their solutions might not be readily applied to existing service-oriented applications, unless those applications are modified to comply with their proposed extended model; they tend to neglect service response time-as it is perceived at the client-side-as a first-class QoS attribute (e.g.…”

MapReduce Skyline Query Processing with a New Angular Partitioning Approach

“…How to select an appropriate or the best service from many alternative offerings becomes a major concern from the vast user communities [1] [2][3] [4]. In another front, the dynamically of web service environment poses a challenge to the efficiency of QoS-based service selection [5] [6].…”
