Electronic Marketplaces (or e-Marketplaces) require technologies which provide support for the adaptability, flexibility and
the integration of business applications in order to meet rapid changes in business environment. Traditional web technologies
are unable to meet the new business requirements which are derived from the rapid growth of e-Marketplaces. In this research,
a service-oriented framework is proposed in order to address the issues associated with the development of e-Marketplaces.
Specifically, it introduces a generic trading model oriented to e-Marketplaces so as to overcome the inadequacy of existing
models and to facilitate the development of a computational trading process. In the proposed framework, required services
are identified through the utilization of the business-centric trading model. Using a service metamodel, services are equipped
with intelligence such that they work seamlessly and coherently within and across e-Marketplaces. A multi-model driven integrated
development platform has been developed to support the proposed models and framework. The proposed framework and concepts
have been validated through a case study of a mutual funds auction in an e-Marketplace.

Grid computing, which is characterized by large-scale sharing and collaboration of dynamic distributed resources has quickly
become a mainstream technology in distributed computing and is changing the traditional way of software development. In this
article, we present a grid-based software testing framework for unit and integration test, which takes advantage of the large-scale
and cost-efficient computational grid resources to establish a testbed for supporting automated software test in complex software
applications. Within this software testing framework, a dynamic bag-of-tasks model using swarm intelligence is developed to
adaptively schedule unit test cases. Various high-confidence computing mechanisms, such as redundancy, intermediate value
checks, verification code injection, and consistency checks are employed to verify the correctness of each test case execution
on the grid. Grid workflow is used to coordinate various test units for integration test. Overall, we expect that the grid-based
software testing framework can provide efficient and trustworthy services to significantly accelerate the testing process
with large-scale software testing.

The model-driven software development paradigm requires that appropriate model transformations are applicable in different
stages of the development process. The transformations have to consistently propagate changes between the different involved
models and thus ensure a proper model synchronization. However, most approaches today do not fully support the requirements
for model synchronization and focus only on classical one-way batch-oriented transformations. In this paper, we present our
approach for an incremental model transformation which supports model synchronization. Our approach employs the visual, formal,
and bidirectional transformation technique of triple graph grammars. Using this declarative specification formalism, we focus
on the efficient execution of the transformation rules and how to achieve an incremental model transformation for synchronization
purposes. We present an evaluation of our approach and demonstrate that due to the speedup for the incremental processing
in the average case even larger models can be tackled.

Currently, standards for web services are being developed via three different initiatives (W3C, Semantic web services and
ebXML). To the best of our knowledge, no theoretical perspectives underlie these standardization efforts. Without the benefit
of a strong theoretical basis, the results, within and across these initiatives, have remained piecemeal. We suggest ‘Language–Action
Theories’ as a plausible perspective that can effectively define, assess and refine web services standards. In this paper,
we first investigate the existing initiatives to identify commonalities that point to theories of ‘Language–Action’ as an
appropriate theoretical basis for web services standards. Next, we adapt work from these theories to develop a comprehensive
reference framework for understanding web services standards. Finally, we use this reference framework to assess the three
initiatives, and analyze the findings to provide insights for future development and refinement of web services standards.

Model transformation is a core mechanism for model-driven engineering (MDE). Writing complex model transformations is error-prone,
and efficient testing techniques are required as for any complex program development. Testing a model transformation is typically
performed by checking the results of the transformation applied to a set of input models. While it is fairly easy to provide
some input models, it is difficult to qualify the relevance of these models for testing. In this paper, we propose a set of
rules and a framework to assess the quality of given input models for testing a given transformation. Furthermore, the framework
identifies missing model elements in input models and assists the user in improving these models.

Relooking at services science and services innovation 总被引:1,自引:0,他引:1
In lots of countries, service economy has become the dominant economy. Modern services industries require talents skillful
at multidiscipline subjects including IT services, business models, management skills, psychology, etc. There is the rise
of services science, service-oriented computing, and services computing. The multidiscipline features bring new challenges
for services science. In this paper, we go beyond the traditional view of services and propose a three-layer framework for
services science and services innovation. The framework covers service needs, service competencies, and service resources.
We believe that these are the common building blocks and foundations for modern services industries. We use Amazon as an example
to show the relevant of the framework for analyzing patterns of services innovation. We also use this framework to derive
a set of service curricula for training talents for modern services.

The growing scale and complexity of the enterprise computing systems under distributed and heterogeneous environments present
new challenges to system development, integration, and maintenance. In this paper, we present a model driven Web service development
framework to combat these challenges. The framework capitalizes on the unified modeling language (UML) profile for enterprise
distributed object computing (EDOC), MDA (model-driven architecture) and Web services. Within the framework, firstly, a general
PIM (platform independent models) is created using the EDOC CCA structural specification and CCA choreography specification
which defines the general functions of a system. Secondly, the general PIM is broken down into sub-PIMs according to functional
decomposition, each of which can provide service independently and will be implemented in a Web service. Thirdly, all of the
PIMs are transformed to Web service interface models for publication and invoking. Afterward, transform each PIM to a BPEL
specified Web service orchestration model. Finally, supported by model transform techniques, the sub EDOC PIMs are implemented
into Web services on specific platforms. Automatic model transformation is the key to this framework, therefore, the transformation
from EDOC CCA models to WSDL specified Web service interface models and the transformation from EDOC CCA models to BPEL specified
Web service orchestration models are deeply discussed, and the detailed transformation rules are proposed. A case study is
also provided to demonstrate the effectiveness of these rules and the merits of this framework.

In this paper we present an application fostering the integration and interoperability of computational lexicons, focusing
on the particular case of mutual linking and cross-lingual enrichment of two wordnets, the ItalWordNet and Sinica BOW lexicons.
This is intended as a case-study investigating the needs and requirements of semi-automatic integration and interoperability
of lexical resources, in the view of developing a prototype web application to support the GlobalWordNet Grid initiative.

Requirements compliant software is becoming a necessity. Fewer and fewer organizations will run their critical transactions
on software that has no visible relationship to its requirements. Businesses wish to see their software being consistent with
their policies. Moreover, partnership agreements are pressuring less mature organizations to improve their systems. Businesses
that rely on web services, for example, are vulnerable to the problems of their web service providers. While electronic commerce
has increased the speed of on-line transactions, the technology for monitoring requirements compliance—especially for transactions—has
lagged behind. To address the requirements monitoring problem for enterprise information systems, we integrate techniques
for requirements analysis and software execution monitoring. Our framework assists analysts in the development of requirements
monitors for enterprise services. The deployed system raises alerts when services succeed or fail to satisfy their specified
requirements, thereby making software requirements visible. The framework usage is demonstrated with an analysis of ebXML
marketplace specifications. An analyst applies goal analysis to discover potential service obstacles, and then derives requirements
monitors and a distributed monitoring system. Once deployed, the monitoring system provides alerts when obstacles occur. A
summary of the framework implementation is presented, along with analysis of two monitor component implementations. We conclude
that the approach implemented in the framework, called ReqMon, provides real-time feedback on requirements satisfaction, and
thereby provides visibility into requirements compliance of enterprise information systems.

The Stanford Event Heap has been shown to provide appropriate support for constructing interactive workspace applications.
Given this success it is natural to consider the Event Heap as a platform to support other classes of Ubiquitous Computing
applications. In this paper we argue that the distributed, spontaneous nature of these applications places additional demands
on the Event Heap that require extensions to both the engineering and API. Suitable extensions are described and their use
to support a typical Ubicomp application is discussed.

IMS is the only standardized way to offer IP based services that are enabled by one common core and all types of access networks
and devices. The management of devices can benefit services enabling and improve user experience. This paper presents the
device management issues in the IMS. Requirements of device management are presented and a management architecture is proposed
to satisfy the requirements. The architecture utilizes distributed design by separating management and executing functionalities
and provides service provisioning and tracing functionalities to application servers utilizing some IMS capabilities. Some
approaches to integrate more IMS capabilities in device management architecture are discussed. A possible evaluation model
for quality of device management from the perspective of user and management authority is proposed.

In this paper, we present a method for development and specification of web services based on the quality system documentation.
The general assumption is that service oriented architecture is based on business services and these business services mostly
correspond to exchanged documentation in a real business system. Documentation of a quality system is recognized in form of
documents that describe business processes in a real business system and identify exchanged documentation with environment.
Presented method uses documentation of quality system and documentation flow for web service specification. We developed the
CASE tool for web service specification based on a new approach, and we compare it to other existing tools.

In this article, we present a conceptual model and a web-based architecture for implementing an enterprise-wide modeling system
for decision support. It describes a framework and develops a method that is aimed at effectively organizing, integrating,
and reusing knowledge and model components from various sources across an organization in order to provide better knowledge
access to decision makers. Given a query, the compositional modeling system responds with automatically building models for
the described scenario by searching the organizational knowledge base and retrieving and integrating relevant knowledge components.
We conclude with outlining an illustrative business example that demonstrates how our enterprise modeling system can be applied
as useful tool for operational and strategic decision-making.

Model transformations can be used in many different application scenarios, for instance, to provide interoperability between
models of different size and complexity. As a consequence, they are becoming more and more complex. However, model transformations
are typically developed manually. Several code patterns are implemented repetitively, thus increasing the probability of programming
errors and reducing code reusability. There is not yet a complete solution that automates the development of model transformations.
In this paper, we present a novel approach that uses matching transformations and weaving models to semi-automate the development
of transformations. Weaving models are models that contain different kinds of relationships between model elements. These
relationships capture different transformation patterns. Matching transformations are a special kind of transformations that
implement methods that create weaving models. We present a practical solution that enables the creation and the customization
of different creation methods in an efficient way. We combine different methods, and present a metamodel-based method that
exploits metamodel data to automatically produce weaving models. The weaving models are derived into model integration transformations.
To validate our approach, we present an experiment using metamodels with distinct size and complexity, which show the feasibility
and scalability of our solution.

Over the last 15 years, database management systems (DBMSs) have been enhanced by the addition of rule-based programming to
obtain active DBMSs. One of the greatest challenges in this area is to formally account for all the aspects of active behavior
using a uniform formalism. In this paper, we formalize active relational databases within the framework of the situation calculus
by uniformly accounting for them using theories embodying non-Markovian control in the situation calculus. We call these theories
active relational theories and use them to capture the dynamics of active databases. Transaction processing and rule execution is modelled as a theorem
proving task using active relational theories as background axioms. We show that the major components of an ADBMS, namely
the rule sets and the execution models, may be given a clear semantics using active relational theories. More precisely: we
represent the rule set as a program written in a suitable version of the situation calculus based language ConGolog; then
we extend an existing situation calculus based framework for modelling advanced transaction models to one for modelling the
execution models of active behaviors.

Mobile communications beyond 3G will integrate different (but complementary) access technologies into a common platform to deliver value-added services and multimedia content in an optimum way. However, the numerous possible configurations of mobile networks complicated the dynamic deployment of mobile applications. Therefore, research is intensely seeking a service provisioning framework that is technology-independent, supports multiple wireless network technologies, and can interwork high-level service management tasks to network management operations. This paper presents an open value chain paradigm, a model for downloadable applications and a mediating platform for service provisioning in beyond 3G mobile settings. Furthermore, we introduce mechanisms that support a coupled interaction between service deployment and network configuration operations, focusing on the dynamic provisioning of QoS state to data path devices according to the requirements of dynamically downloadable mobile value-added services (VAS).

The advancement of web services in the last few years has spurred a number of revolutionary concepts in information technology
and management including service-oriented architectures, service-oriented computing, and services science, management and
engineering, which can be collectively called as “services computing.” Services computing is a new research field that goes
beyond traditional computing disciplines as it includes not only architectural, programming, deployment, and other engineering
issues, but also management issues such as business component modeling, business process design, and service delivery. In
this paper, we provide an overview of emerging research concepts in services computing without attempting to unify them as
it will take sometime for the field to become mature. In addition, we take a position that the ultimate goal of services computing
is to create the necessary technological and managerial foundation to support enterprise agility. In this short paper, we
give an overview of services computing, describe its relationship to enterprise agility, and discuss basic technical and managerial
issues. Finally, we introduce the papers that are published in this special issue.
