with the increased confidence in the use of the internet and the world wide web, the number of electronic commerce (e-commerce) transactions is growing rapidly. therefore, finding useful patterns and rules of users’ behaviors has become the critical issue for e-commerce and can be used to tailor e-commerce services in order to successfully meet the customers’ needs. this paper proposes an appro...

An ontology for Semantic Web Services is proposed in this paper, whose intention is to enrich Web Services description. Distinguish from the existing ontologies, the proposed ontology is based on both functionalities and performances, and it is organized as a layered construction. The discovery related with the proposed ontology is also discussed. Based on the Service Oriented Architecture, the...

Web services are one of the most popular ways for building distributed Web Information Systems (WIS). In this paper we propose a distributed implementation of the Hera methodology, a methodology based on models that specify the different aspects of a WIS. The Web services used in the implementation are responsible for capturing the required data transformations built around specific Hera models...

Web services have emerged as a major technology for deploying automated interactions between distributed and heterogeneous applications. The main advantage of Web services composition is the possibility of creating value-added services by combining existing ones to achieve customized tasks. How to combine these services efficiently into an arrangement that is both functionally sound and archite...

This paper proposes a model of ubiquitous video services and management systems for solving current issues of video surveillance services and management in the smart city. The author presents the Enterprise Service Bus (ESB) based methods of integrating and using existing video resources in civil defense emergency commanding by providing a use case “Civil Defense Emergency Command Center in Hua...

Automated web service composition is one of the major promises of serviceoriented architecture, where services can be discovered and composed dynamically and automatically. To investigate the methods for composite web service construction, we conducted an experiment on creating useful composite web services from real existing web services where semantic annotations are not available. The empiri...

The problems related to the consumption of alcohol vary along a gravity continuum. Such a characteristic requests the construction of treatment services that assist to the needs in each one of these situations. Besides, the economical and cultural context of a given community covers the patient of particularities that need to be considered by the service of treatment. This way, the organization...

Wind power is the fastest growing renewable energy source in the United States. Existing empirical studies on the economic impact of wind power development have primarily relied on case studies and input-output models, which have limitations. This study instead uses a linear fixed effects model to estimate the county level effects of wind power in the Great Plains region of the United States fr...
