Semantic Support for Change Management,Semantic support is always considered as the key enabler for automation. With the help of machine-processible semantics, software agents can understand the functionality and performance of a Web service. They can then determine whether a service should be selected as a component of a LCS and how to integrate the service with other components.

Performance Study,In this chapter, we conduct a set of experiments and simulations to evaluate the performance of the process of change management, including ontology query, top-down change enactment, top-down change optimization, and bottom-up change management. We will elaborate on the performance study for each of them in the following sections.

A Supporting Infrastructure of a LCS,onents: . and .. It also contains two supporting components: . and .. A LCS schema is the kernel of a LCS since it defines its high-level business logic. It guides the composition of outsourced Web services to perform the functionality of the LCS. We give the formal definition and analyze the . of the schema.

This book describes taxonomy of changes that are expected in semantic service oriented environments. The process of change management consists of detecting, propagating, and reacting to chang

Top-down Change Language,-down changes. Since a change introduces new requirements on the LCS’s features, we first present a taxonomy that classifies top-down changes based on their requirements. The taxonomy is built on top of the proposed LCS schema. Based on the change taxonomy, we then present the SCML that enables the formal specification of changes.
