The web monitoring is a procedure to detect and monitor the change of a particular information from the web site. In this paper, we propose a monitoring system to survey the response time for the customers chi an internet shopping mall. This system we designed, decreases the network overload and guarantees the accuracy as well as the reliability of the information by using an interactive agent. This interactive agent we constructed, is written in Java and controlled by the high-level information such as the index or the robot. from the N web site, we extracted the web monitoring results of keyword "LCD Monitor" and verified our system's efficiency. The performance of the system is tested and the result is illustrated.

With the development of mobile and wireless environments, the Ubiquitous era has com on the base of technologies of Semantic Web and Web Services. To accelerate proliferation of the E-Commerce in the Ubiquitous era, the importance of information search is emphasized more and more and its time to need more intelligent search for product and service which can consider location and other context-aware related information. As a starting point to meet these requirements, we proposed more effective product information search service framework through web services under semantic web environment. Over the wireless internet and we also examined its technical validity with the prototype system, implemented prototype and investigated the technological possibility.

Web Services are rapidity becoming the enabling technology of today's e-business and e-commerce systems, and will soon transform the Web into distributed applications. The aim of this paper is to present our approach in applying Web Services into the Internet transaction banking system. The system is integrated among backend system of banks so that each bank system can communicate with each other in order to perform transactions in transferring money from an account in one bank to an account in the partner bank and vise versa. The backend systems of banks are heterogeneous information systems; therefore it is difficult to build a common environment using existing distributed technologies. Web Services provide a means for different organizations to connect their applications with one another to conduct business across a network in a platform and language independent manner [1]. The paper will examine these benefits of Web Services and apply these features into the Internet banking transaction system regardless of platform, programming languages as well as existing backend system of banks.

In this paper, we developed those Directory Services based on the Web-Service, because Web-Service environments provide a suitable method to gather requested information in an appropriate way. The proposed architecture cooperate with other OpenLS(Open Location Service) Core Services ( Location Utility Service and Router Determin ation service) and is an interoperability one - it ident ifies those global elements of the global Web-Services network that are required in order to ensure interoperability between Web-Services. In this paper, a new architecture of Directory Service with OpenLS Core Services is proposed and tested in OpenLS Core Services environments.

인터넷에 존재하는 웹문서와 사이트들은 충분히 학술적 가치를 갖고 있기 때문에 중요한 정보원으로 간주된다. 도서관은 이 새로운 정보원을 대상으로 도서관 이용자를 위한 새로운 검색기법과 관리기법을 개발할 필요가 증대되었다. 왜냐하면 현재 웹검색엔진에서 제공하는 분류체계는 도서관학적 관점에서 개발되지도 않았으며 또한 웹검색엔진간 분류체계의 설계원칙도 없기 때문이다. 본 논문에서는 이점에 착안하여 웹 문서를 효율적으로 검색할 수 있는 실험적인 새로운 웹문서 분류체계를 설계하였다. 설계는 해당 분류항목과 연관된 웹문서의 수와 접속비율에 근거하였으며, 설계의 수준은 1차적으로 류${\cdot}$강항목까지 제한하였다.

The purpose of this paper is to propose an analytical model for evaluating Internet Web sites, that is comprehensive and flexible enough to accomodate different categories of Internet Web sites. This paper is intended to identify critical success factors of Internet Web sites to determine criteria for evaluating the Web sites, and use the criteria to develop a framework for comprehensive evaluation of Internet Web sites. The framework consists of eight categories, including design, business functions, trustworthiness, interface, technology, community, contents, and others. An empirical study designed to validated the framework has been conducted for each of the three Web site categories, including (1) information provision, (2) product sale, and (3) customer service. The results show that ‘content ’ is the most important for information provision Web sites, ‘trustworthiness’for product sale Web sites, and ‘design’ for customer service Web sites. The framework may be used not only as a tool to evaluate Internet Web sites, but also as a checklist to improve the quality of a Web site that is under development.

The purposes of this study are in threefold; to explain the interactivity in web site, to extend the Technology Acceptance Model(TAM) in the WWW context, and to examine its relationship with the existing TAM components. We proposed that the WWW is not just web systems but interactive spaces for virtual community. Web interactivity is represented by the two constructs: system interactivity and social interactivity. We extended and empirically examined the TAM for the web context. An individual's attitude toward the use of the web site is significantly affected by the individual's perception about ease of use, usefulness, and system interactivity. At the same time, behavioral intentions to use the web site is highly related to the social interactivity. The results showed that the system interactivity and social interactivity of a web site are important factors in affecting the user's beliefs and behavior intention of such a web site, So web page providers not only have to make the web site useful and easy to use, but also need to design an interactive web page by putting both systemic aspects and social aspects.

The Internet has been expanded constantly and greatly such that we are having vast number of web pages with dynamic changes. Especially, the fast development of wireless communication technology and the wide spread of various smart devices enable information being created at speed and changed anywhere, anytime. In this situation, web crawling, also known as web scraping, which is an organized, automated computer system for systematically navigating web pages residing on the web and for automatically searching and indexing information, has been inevitably used broadly in many fields today. This paper aims to implement a prototype web crawler with Python and to improve the execution speed using threads on multicore CPU. The results of the implementation confirmed the operation with crawling reference web sites and the performance improvement by evaluating the execution speed on the different thread configurations on multicore CPU.

The rapid development of information and communication technologies has resulted in rapid increase in the qualitative and quantitative information that can be accessed by information technology. Furthermore an enormous amount of information is provided in various formats. However, there are a group of people who are not able to even approach to targeted information due to physical or environmental problems. Visually handicapped users constitute a class of these users. In this paper, a method of developing user interface for web-based education service is described for the visually handicapped users to access information more efficiently. First, this paper analyzed the problems of visually handicapped users to access information targeting representative domestic sites that supply education services. And based on the results of the above analyses, Nest, this paper explains the web-based education service interface implementation method according to types of the content to be delivered. Lastly, the validity of this method is provided by testing a web page based on the implementation method according to the types of content.

최근의 정보시스템은 웹기반 정보시스템이며 이의 개발과 유지보수 시에 "웹 위기" 현상이 발생하고 있다. 이를 해결하기 위해, 웹 공학 기술 중 웹기반 어플리케이션에 대한 소프트웨어 클러스터링 기술이 필요하다. 본 논문에서는 웹기반 정보시스템의 내부시스템 재구성을 위한 폼 클러스터링 알고리즘을 제시한다. 폼 클러스터링 알고리즘은 웹기반 정보시스템의 다양한 구조모델 중에서 웹의 특징이라 할 수 있는 페이지 모델에 초점을 맞춘다. 특히, 그래프 형태의 항해구조를 분석이 용이한 계층구조로 분석하기 위해 거리 척도 개념을 응용하고, 부하가 큰 핵심 기능객체를 파악하기 위하여 웹 로그분석 기술을 적용한다. 또한,2단계에 걸친 클러스터링 과정을 통해 재사용 성을 극대화하고 부하 균형화를 위한 하드웨어 할 당시에 사용할 수 있는 웹 소프트웨어 구조를 생성한다. 본 논문에서 제시한 폼 클러스터링 알고리즘은 웹기반 정보시스템의 신규 개발 또는 유지보수 시에 재사용 가능한 웹 컴포넌트 개발 및 부하균형화를 위한 하드웨어 할당 시에 적용할 수 있다.
