We propose an integrated framework that manages changes in long term composed services. The main procedure of change reaction is presented. One of the most challenging research issues of change management is how to automate the process of change reaction. To address this issue, we propose a semantic support, which centers around a tree-structured Web service ontology. The ontology is expected to provide sufficient semantic for change reaction. We propose a set of algorithms for efficiently querying semantics from the ontology. We conduct a set of experiments to evaluate the performance of the proposed algorithms.

The service-oriented architecture (SOA) has been successfully applied in enterprise environments. Due to decentralized set-ups, mergers and acquisitions and organizational boundaries, many enterprises today operate multiple, fragmented and heterogeneous service infrastructures that are administered by different organizational units. This fragmented infrastructure causes service duplication and unnecessary redundancy. This paper proposes an approach of cross-domain service integration through an automated federation of Enterprise Service Buses (ESBs). ESBs are the mediation centers within a service domain that enable service interaction across technological boundaries by using service proxies. We present DISCE, a configuration engine prototype that enables an operator to configure service connectivity in such an environment in a declarative form, by specifying simple rules. The engine produces a configuration consisting of a set of proxies interconnecting clients and services.

Services computing paradigm together with Web services have significantly promoted the automation of business process in enterprise. Prevalent service composition technologies, such as WS-BPEL and WSCI, provide promising means to deal with machine-to-machine communication. Traditionally, in the phase of business process modeling, there usually require some human-involved tasks. Recent new technologies such as BPEL4People and Human Task begin to consider involving human interaction in business process. However, such approaches still have some limitations. On one hand, they exactly require some extensions of current BPEL standards. As a result, the existing business processes have to be rewritten and redeployed. On the other hand, they yet lack of the development and deployment supports of flexible and reusable user interfaces in business process. In this paper, we address these issues by enabling human interaction in business process with rich web applications. Our approach models human tasks as services, and can be seamlessly integrated to current BPEL without any modifications to existing engine and processes. We further support building human task presentations from service-oriented rich user interfaces. During the process execution, the corresponding task stakeholders can select, configure and compose these reusable and rich UI components according to their own application context.

We propose a fuzzy trust management framework for the Service Web. The proposed framework supports a natural way of representing and querying consumers’ perception on services. We describe the underlying models, algorithms and an implementation architecture, mainly focusing on the key features and contributions of the proposed framework.

This paper proposes a document based framework for the modeling of web-based choreographies involving a tight combination of workflow and data management. Our starting point is Active XML proposed by S. Abiteboul — AXML documents are XML documents with embedded service calls. We enhance Active XML with a rich notion of interface and we propose an effective technique to decide if provided services and needs of callers (defined as interfaces) are compatible. We also explicitly take distribution into account and allow for the composition of distributed AXML systems.

WS-BPEL processes are usually overlapped in large Business applications composed of several Web Services. Such applications are more and more developed with respect of quality processes. Testability is an important quality degree, which evaluates the fault detection coverage during the testing process and the testing cost. In this paper, we focus on a well-known testability criterion called observability, which evaluates if enough distinguishable events can be observed while testing. We study the observability of ABPEL (Abstract-BPEL) specifications and we describe some ABPEL observability degradation properties. From these, we propose some observability enhancement methods which detect observability issues in ABPEL specifications and semi-automatically update the ABPEL code.

Modern scientific computations are usually data intensive, involving large-scale, heterogeneous and structured scientific datasets. Modeling, organizing, and processing scientific data have become key challenges for scientific workflow management systems (SWFMSs). In contrast to business data, which is usually relational and stored in databases, scientific data is often hierarchically organized and collection oriented. Although several data models have been proposed for SWFMSs, none of them provides a formal data model with a set of well-defined operators. In this paper, we take a first step towards formalizing a collection-oriented data model, called collectional data model, to model hierarchical collection oriented scientific data, and a set of well-defined operators to manipulate and query such data. We then apply the collectional data model to VIEW, a dataflow-based scientific workflow composition framework, whose workflow constructs are extended to support collections. We implement our techniques and validate them by a case study in a biological simulation project.

In dynamic e-business, organizations collaborate in a just-in-time fashion using loosely coupled services. To ensure interoperability of the services, behavioral mismatches between their protocols need to be resolved in a fast and efficient way, which can be done with protocol adaptors. We present an efficient, automated method to construct (if possible) a minimal protocol adaptor with parallelism for two asynchronously communicating business protocols. A minimal adaptor only processes those messages that cause the mismatch, and has less message overhead at run-time than a non-minimal adaptor. Existing methods only build adaptors that are sequential, synchronous, or non-minimal. We show that the proposed method increases the efficiency of service adaption both at run-time and design-time.

Survivability is crucial for computer systems that support critical infrastructures of our society. For those in paradigm of SOA where the computing settings are intrinsically open, traditional survivability model and safeguard mechanisms are no longer applicable. To rise to the challenge, we propose a formal definition and a corresponding framework to evaluate the survivability of SOA systems. We treat survivability as a multidimensional QoS property, and then give a holistic evaluation method based on the Hidden Markov Model.

Web service has already been an important paradigm for web applications. Growing number of services need efficiently locating the desired web services. The similarity metric of web services plays important role in service search and classification. The very small text fragments in WSDL of web services are unsuitable for applying the traditional IR techniques. We describe our approach which supports the similarity search and classification of service operations. The approach firstly employs the external knowledge to compute the semantic distance of terms from two compared services. The similarity of services is measured upon these distances. Previous researches treat terms within the same WSDL documents as the isolated words and neglect the semantic association among them, hence lower down the accuracy of the similarity metric. We provide our method which tries to reflect the underlying semantics of web services by utilizing the terms within WSDL fully. The experiments show that our method works well on both service classification and query.
