WSPred: A Time-Aware Personalized QoS Prediction Framework for Web Services

Abstract: The exponential growth of Web service makes building high-quality service-oriented applications an urgent and crucial research problem. User-side QoS evaluations of Web services are critical for selecting the optimal Web service from a set of functionally equivalent service candidates. Since QoS performance of Web services is highly related to the service status and network environments which are variable against time, service invocations are required at different instances during a long time interval for making accurate Web service QoS evaluation. However, invoking a huge number of Web services from user-side for quality evaluation purpose is time-consuming, resource-consuming, and sometimes even impractical (e.g., service invocations are charged by service providers). To address this critical challenge, this paper proposes a Web service QoS prediction framework, called WSPred, to provide time-aware personalized QoS value prediction service for different service users. WSPred requires no additional invocation of Web services. Based on the past Web service usage experience from different service users, WSPred builds feature models and employs these models to make personalized QoS prediction for different users. The extensive experimental results show the effectiveness and efficiency of WSPred. Moreover, we publicly release our real-world time-aware Web service QoS dataset for future research, which makes our experiments verifiable and reproducible.

Systems and method for resource tracking in information management environments

Abstract: Methods and systems for providing differentiated service that may be employed, for example, to deliver content or services in a network environment. Differentiated services that may be so delivered include both differentiated information service that may be implemented, for example, at the system and/or processing level, as well as differentiated business service that may be implemented, for example, to differentiate information exchange between different network entities such as different network provider entities, different network user entities, etc. The methods and systems may include or facilitate provisioning of system service parameters such as service level agreement (“SLA”) policies and may be employed in network computing system environments to enable differentiated service provisioning, for example, in accordance with business objectives.

Reputation-Enhanced QoS-based Web Services Discovery

Abstract: With an increasing number of Web services providing similar functionalities, quality of service (QoS) is becoming an important criterion for selection of the best available service. Currently the problem is twofold. The Universal Description, Discovery and Integration (UDDI) registries do not have the ability to publish the QoS information, and the authenticity of the advertised QoS information available elsewhere may be questionable. We propose a model of reputation-enhanced QoS- based Web services discovery that combines an augmented UDDI registry to publish the QoS information and a reputation manager to assign reputation scores to the services based on customer feedback of their performance. A discovery agent facilitates QoS-based service discovery using the reputation scores in a service matching, ranking and selection algorithm. The novelty of our model lies in its simplicity and in its coordination of the above mentioned components. We present experiments to evaluate the effectiveness of our approach using a prototype implementation of the model.

Systems and methods for performing integrated financial transactions

Abstract: A system for a small business owner to manage a plurality of different financial accounts and services and to perform a number of different financial transactions wherein each of the transactions may involve multiple subtransactions which occur among different financial service providers. The system includes a network basedsystem which includes a plurality of client systems (12) connected through a network (20) such as the Internet IP network or server system (14) which can connect to financial service providers (18). Server (14) is also coupled to a database (16) that stores information representative of subscriber's accounts.
