Composing Web services on the Semantic Web
This paper proposes an ontology-based framework for the automatic composition of Web services with formal safeguards for meaningful composition through the use of composability rules, and provides an implementation using an E-government application offering customized services to indigent citizens.
RATEWeb: Reputation Assessment for Trust Establishment among Web services
This work proposes a set of decentralized techniques that aim at accurately aggregating the submitted ratings for reputation assessment and conducts experiments to assess the fairness and accuracy of the proposed techniques.

A set of criteria for assessing the different B2B interaction techniques, standards, and products is proposed, and several issues related to scale, content exchange, autonomy, heterogeneity, and other issues still need to be addressed.
Deploying and managing Web services: issues, solutions, and directions
This survey focuses on investigating the different research problems, solutions, and directions to deploying Web services that are managed by an integrated Web Service Management System and conducts a comparative study on how current research approaches and projects fit in.
A multilevel composability model for semantic Web services
A composability model is proposed to ascertain that Web services can safely be combined, hence avoiding unexpected failures at runtime, and the concepts of composability degree and /spl tau/-composability to cater for partial and total composability are introduced.

A cloud service composition framework that selects the optimal composition based on an end user's long-term Quality of Service (QoS) requirements is proposed that uses QoS time series' inter correlations and performs a novel time series group similarity approach on the predicted QoS values.
Efficient Service Skyline Computation for Composite Service Selection
A novel bottom-up computation framework is proposed that enables the skyline algorithm to scale well with the number of services in a composition, and a comprehensive analytical and experimental study is conducted to evaluate the effectiveness, efficiency, and scalability of the composite skyline computation approaches.
Efficient agglomerative hierarchical clustering
QoS Analysis for Web Service Compositions Based on Probabilistic QoS
Experimental results show that the proposed QoS calculation approach significantly improves the efficiency in probabilistic QoS estimation.
