This paper studies the need to integrate trust and Technology acceptance model TAM to understand the behaviour intention of the customer to use mobile banking. The present study focuses through literature review on trust related antecedents and technology related constructs and its influence on customer decision. It covers disposition to trust, institution-based trust, cognitive-base trust, security and privacy as five potential antecedents of trust. The study concludes that two technology attributes which are perceived ease of use and perceived usefulness to be beneficial for the usage of mobile banking. It suggests an integrated model that incorporates the five trust antecedents and two technology-related antecedents on its influence on customers' decision to use mobile banking.

Service-oriented systems are performed in a highly dynamic and heterogeneous environment to achieve a user's business requirements. In this paper, we introduce a case-based reasoning approach to improve the system's fault-tolerant ability meeting the end-to-end Quality-of-Service QoS constraints. We consider and quantify the fault information and QoS information together in a case. In addition, one case also includes one solution to cope with the corresponding fault. When a new fault occurs, its failure symptoms are extracted and matched against the case base to look for the most similar case. Furthermore, solution templates are presented considering the business process structure features. We also develop an influential region-based algorithm to minimise the handle cost. Based on our proposed method, a fault-tolerant framework is implemented. Comprehensive experiments are conducted employing a real QoS dataset and the experimental results show that our approach improves the fault-tolerant capability encouragingly.

A fault-tolerant framework for QoS-aware web service composition via case-based reasoning

Prior research has devoted considerable attention to consumer hedonic experience and customer satisfaction in retailing and online shopping settings. However, very little effort has been made to investigate the relationship between hedonic experience and customer satisfaction in the context of information system use. To fill this gap, this study investigates the effect of hedonic experience on game player satisfaction using an adapted technology acceptance model. By doing so, this article addresses the core research question: What drives online game player satisfaction? In support of the model and most of the hypotheses, the empirical results not only identify key antecedents of enjoyment and perceived usefulness, but also confirm the significant role of the two constructs in predicting player satisfaction. This study thus helps both information systems and marketing researchers attain a better understanding of customer satisfaction, expand their baseline knowledge of hedonic experience constructs, and conduct more fruitful and illuminating future research on e-commerce service.

Ontologies are knowledge structures to explicate the contents, essential properties, and relationships between terms in a knowledge source. Many sources are now accessible with associated ontologies. Most prior work on use of ontologies relies on the construction of a single global ontology covering all sources. Such an approach is not scalable and maintainable especially when the sources change frequently. We propose a scalable and easily maintainable approach based on the interoperation of ontologies. To handle user queries crossing the boundaries of the underlying information systems, the interoperation between the ontologies should be precisely defined. Our approach is to use rules that cross the semantic gap by creating an articulation or linkage between the systems. The rules are generated using a semi-automatic articulation tool with the help of a domain expert. To make the ontologies amenable for automatic composition based on the accumulated knowledge rules, we represent them using a graph-oriented model extended with a small algebraic operator set. ONION, a user-friendly toolkit, aids the experts in bridging the semantic gap in real-life settings. Our framework provides a sound foundation to simplify the work of domain experts, enables integration with public semantic dictionaries, like Wordnet, and will derive ODMG-compliant mediators automatically.

A Graph-Oriented Model for Articulation of Ontology Interdependencies

Traditional web service composition is often statically generated using knowledge available at the design time. In addition, they assume the final composition workflows are always executable. However, this assumption might be false since the environment can change during the execution time. Therefore, it is essential that the correctness of a partial/full composition needs to be validated and maintained during its execution. This paper utilises the notion of workflow exception handling to generate valid web service compositions. More specifically, we propose the concepts of synchronous exception handling and asynchronous service interrupt (ASI). The synchronous workflow exception is used in the initial service configuration which contains static service substitution, planning time-service adaptation and mapping time-service adaptation, while the ASI is implemented via dynamic service substitution and binding time-service adaptation. The integrated usage of the above approaches is demonstrated by an implementation of an e-hospital application.

Building a valid web service composition using integrated service substitution and adaptation

With the increasing demand for dynamic web service composition, traditional web service registries are no longer adequate in providing precise service selection. To address this problem, the paper proposes a fine-grain structural concept for traditional service registries, called web service community. Efficient semantic-level service enquiry and community management depend on context information. This paper investigates the issue of context modeling and proposes four categorizations of context information for service composition. Several design issues that relate to these context information are discussed, including community organization, context-aware management and semantic-level web service query.

Enhancing Web Service Registries with Semantics and Context Information

Traditional web service composition is often statically generated using knowledge available at the design time. However, in practice, composed web services must cope with changing environment at run time to maintain the usability of current composition plan. In this paper, we propose a solution for web service composition based on adaptation to avoid the problem of such invalidated running composition plans. In addition, we add another layer of process between adaptation and composition, called substitution, in the system architecture. The objective of the research is to show that adaptation and substitution complement each other, and their integration in the system provides best flexibility and efficiency for web service composition and execution during the design time and running time, respectively.

There exist an increasing number of online databases searchable only through query interfaces. Meta-queriers with an integrated query interface are a practical solution to effective searching of information from multiple data sources. The diversity of user demands and their frequent changes necessitate the need for dynamic and personalized meta-queriers. This paper presents a mapping management system, called M-Repository, to facilitate the implementation of meta-queriers with two innovative features: personalized source selection and dynamic reconfiguration. To support such two features, M-Repository is designed to contain two unique functionalities: 1) reuse-oriented mapping discovery, 2) semantic-based mapping organization. This paper describes the models and implementation structure of M-Repository. Experiments are conducted on real-world query forms, and the results show that the approach is feasible and effective.

Dynamic personalization for meta-queriers

This paper proposes a light-weight adaptation process, called service substitution-based adaptation. The main idea for this solution is that similar web services can be replaced with each other at lower cost. Thus, invalid composite services can be adapted by substituting its out-of-dated sub-services.
