As the value of B2B integration gets more importance and the business process becomes more complex, BPEL4WS standard has been focused for the solution of the problems which is based on web service technology. Many vendors implement the standard in their systems to integrate B2B and web service based inner-Enterprise Application(EA)s. But there is no way to use the standard to integrate non-web service based EAs, because the standard is designed only for Service Oriented Architecture (SOA) over web services. This paper proposes Hybrid Service Orchestration Framework to participate web services and also non-web service based EAs in the business process as a partner using BPEL4WS standard. The framework introduces Hybrid Service Architecture to represent non-web service based EAs as a service, so BPEL4WS could be used to integrate web services and non-web service based EAs. And the framework also introduces Hybrid Service Toolkit to support software level facilities. The paper also introduces Hybrid Orchestration System that is based on Hybrid Service Orchestration Framework.

A web robot is a software that has abilities of tracking and collecting web documents on the Internet(l), The performance scalability of recent web robots reached the limit CIS the number of web documents on the internet has increased sharply as the rapid growth of the Internet continues, Accordingly, it is strongly demanded to study on the performance scalability in searching and collecting documents on the web. 'Design of web robot based on Multi-Agent to speed up documents collection ' rather than 'Sequentially executing Web Robot based on the existing Fork-Join method' and the results of analysis on its performance scalability is presented in the thesis, For collection speedup, a Multi-Agent based web robot performs the independent process for inactive URL ('Dead-links' URL), which is caused by overloaded web documents, temporary network or web-server disturbance, after dividing them into each agent. The agents consist of four component; Loader, Extractor, Active URL Scanner and inactive URL Scanner. The thesis models a Multi-Agent based web robot based on 'Amdahl's Law' to speed up documents collection, introduces a numerical formula for collection speedup, and verifies its performance improvement by comparing data from the formula with data from experiments based on the formula. Moreover, 'Dynamic URL Partition algorithm' is introduced and realized to minimize the workload of the web server by maximizing a interval of the web server which can be a collection target.

Web-based services have fundamentally confidential problems due to characteristics of internet environment such as anonymity. These problems are serious obstacles to grow the web-based services. The security and confidence of web-based services rely on both service provider and users' opinion. But the former has difficulty in trusting the service provider and the latter takes too long time to propagete all users after converging their opinion. Therefore it is necessary to establish the objective and confidential evaluation and certification program for web-based service. In this paper, the internal and external web-based services evaluation and certification programs are compared and analyzed. The critical factors and evaluation methodology for secure and confidential web-based service are identified. Finally, this paper provides the improvement and strategy for web-based services evaluation and certification program.

Firms increasingly utilize Social Networking Service(SNS) to lead user's voluntary behavior. In the web-based environment, users show coexist loyal behavior which is represented by 'web-based pro-organization citizenship behavior' and 'anti-citizenship behavior'. To measure genuine performance of web-activity, we separated degree of compliance based on credibility, 'deep-level' and 'surface-level' to comprehend different behavior after compliance. The analysis result shows that contents credibility is important to enhance deep-level of compliance which has significant influence on web-based pro-organization citizenship behavior. Contrastively, surface-level of compliance has influence on anti-citizenship behavior. Based on the results of these analyses, the directions of web-based activities for the common good and self-interests of the stakeholders of the web-based activities will be proposed.

This study proposes a Natural Language Query Framework (NLQF) on the semantic web to support the intelligent deduction at semantic level. A large number of former researches are focused on the knowledge representation on the semantic web. However, to revitalize the intelligent agent (IA)-based automated e-business contract with human customers, there is a need for semantic level approach to the web information. To enable accessing web information at semantic level, this paper discusses the pattern of complex natural language processing at first, and then the semantic web-based natural language inference in e-business environment. The NL-based approach could help the IAs on the web to communicate with customers and other IAs with more natural interface than traditional HTML-based web information. Therefore, our proposed NLQF will be used in semantic web-based intelligent e-business contracts between customers and IAs.

This paper presents an embodiment of design integration framework corresponding to changes in the latest manufacturing environment. The embodied system is named by 'WEB-KBE System' because it supports a product design with a KBE technique based on web environment. The final purpose of the work is to implement a web-based integration design environment with a KBE technique to support non-skillful designers. The framework of the system Is designed to support necessary items in user-centric design environment. Two case studies were applied to the WEB-KBE system to evaluate the efficiency, flexibility, extensibility, and reusability of the system. The examples are [1] CART integration design environment construction and (2) Exhaust Duct Saddle Support integration design environment construction. In the former case, it took a period of 8 months for modeling and implementation of the WEB-KBE prototype system. However, with the high extensibility and reusability of WEB-KBE system, the second case required only a period of one month for modeling and implementation of the system. We conclude that the presented WEB-KBE system can bring fair effects on implementing a knowledge based design environment in aspect of time and expense.

The web-based groupware systems hold many possibilities for system developers and users. Especially, web-based group collaborative systems are emerging as enterprise-wide information systems. Since data in group collaborative systems are apt to be shared among multiple concurrent users and modified simutaneously by them, the web-based group collaborative systems must support synchronous collaboration in order to provide users with synchronized and consistent views of shared data. However, current web technologies have limitations in supporting this, largely because the existing Hypertext Transfer Protocol(HTTP) is unidirectional and does not allow web servers to send messages to their web browsers without first receiving requests from them. This paper proposes an active web server that can overcome such limitations and facilitate synchronous collaboration in web-based group collaborative systems. To accomplish such goals, the active web server manages dependency relationships beween shared data and web browsers referencing them and actively propagates changing details of the shared data to all web browsers referencing them. And, this paper examines usefulness and effectiveness of the active web server to apply it to the ball-bearing design example of concurrent engineering design systems. The prototype system of the active web server is developed on a commercial Object-oriented Database Management System(0DBMS) called OBJECTSTERE using the C++ programming language.
