WebDAV는 IETF 표준으로서 웹상에서 분산 저작을 지원하도록 HTTP를 확장한 프로토콜이다. WebDAV 클라이언트는 WebDAV 프로토콜을 이용하여 WebDAV 서버자원을 관리하는 도구이다. 현재 WebDAV 기반의 자원 관리가 널리 사용되면서 무선 네트워크 환경에서 동작하는 클라이언트의 필요성이 증대되고 있다. 본 논문에서는 무선 네트워크를 지원하는 PDA에서 동작하는 WebDAV 클라이언트의 구현에 대하여 기술한다. 개발된 클라이언트는 간결한 사용자 인터페이스를 제공하며 WebDAV의 기본 메소드를 지원한다. 사용자는 인터페이스와 기본 메소드를 이용하여 WebDAV 서버에 자원을 등록하고, 서버 자원에 대한 열람, 검색, 이동 및 삭제를 할 수 있으며, 서버 자원을 내려 받을 수 있다. 본 클라이언트는 PDA에서 동작하기 위해서 .NET Compact Framework를 기반으로 구현 하였으며 관련 에뮬레이터를 이용하여 실험하였고 이를 실제 PDA장치인 'HP iPAQ hx2700'에 이식하여 검증하였다.

In this paper, I propose a metric model for measuring complexity of Web documentations which are wrote by HTML and XML. The complexity of Web documentation has effect on documentation understandability which is an important metric in maintenance and reusing of Web documentation. The understandable documents have more effect on WEI. The proposed metric uses the entropy to represent the degree of information flows between Web documentations. The proposed documentation complexity measures the information flows in a Web document based on the information passing relationship between Web document files. I evaluate the proposed metric by using the complexity properties proposed by Weyuker, and measure the document complexity. I show effectiveness of analyzing the correlation between the number of document file and document complexity.

The Semantic Web has appeared to handle information on the web effectively, which has been increasing very rapidly since the web emerged. It refers to the machine, which understands the meaning of information on behalf of human and handles the information automatically that users want. The objective of this research is to help people to understand the Semantic Web as the next generation web by surveying the applications of Semantic Web technologies. To that end, this paper suggests a system framework which can be used for analyzing most of the Semantic Web applications. Using the suggested the framework, the recent Semantic Web applications are analyzed. And then research challenges are discussed to be overcome for the practical Semantic Web based on the analyzed results.

The web uses an asynchronous web method to provide various information having different processing speeds together. The asynchronous method has the advantage of being able to respond to other events even before the task is completed, but a typical crawler has difficulty collecting information provided asynchronously by collecting point-of-visit information on a web page. In addition, asynchronous web pages often do not change their web address even if the page content is changed, making it difficult to crawl. In this paper, we propose a web crawling algorithm considering asynchronous page movement by analyzing links in the web. With the proposed algorithm, it was possible to collect dictionary information on TTA terms that provide information asynchronously.

Users of World Wide Web (Web) experience difficulties in the retrieval of pertinent information due to the increased information provided by Web sites and the complex structure of Web documents that are continuously created, deleted, restructured, and updated. Web providers' efforts to maintain their sites are tend to be less than that of site creation due to the expenses required for maintenance. If information of relationship among Web documents and their validity is provided to Web managers as well as Web developers, they can better serve users. In order to grasp the whole structure of a Web site and to verify the validity of hyperlinks, traversal and analysis of hyperlinks in a Web document are required to provide information for effective and efficient creation and maintenance of the Web. In this paper, we introduce a Web Editor specialized for Web maintenance. We emphasized on two aspects: first, the analysis of HTML Tags to extract hyperlink information and second, establishment of the relationship among hyperlinked documents, and verification of the validity of them.

As the requirements of web apps become complex and rapidly changing, the maintenance of web apps becomes more important. However, web apps have a problem that more often than not there is not enough documentation to understand and maintain them. Thus, their effective maintenance requires models that represent their internal behavior occurring when they dynamically generate web pages. Previous works identify web components (such as JSPs and Servlets) as participants in the behavior but not web resources (such as images, CSS files, and JavaScript files). Moreover, they do not identify dependency relations between web components and web resources. This paper dynamically analyzes Java web apps to extract such dependency relations, which are included in our graph model for page generation. Case studies using open-source web apps show the applicability of the proposed approach.

본 연구에서는 국내 무용인들의 정보요구를 수렴한 학술정보 시스템의 구축 방안을 제시하기 위해, 현재 운영되고 있는 국내 web 무용정보의 정보량과 품질을 분석하였고, 설문조사를 통해 무용정보 시스템의 실질적인 이용자인 국내 무용인의 정보이용 현황 및 정보요구를 분석하였다. 1999년 8월 현재 국내 무용 web site는 68개이고, 이중 98.6% 가 구축하고 있는 web 문서의 수는 40 페이지 미만이었다. 시스템과 이용자 인터페이스 측면과 정보제공 측면으로 품질을 평가한 결과 대부분이 개략적이고 형식적으로 구축되어 이들로부터 유용한 정보를 입수하는 것은 기대할 수 없는 상황이었다. 국내 무용인을 대상으로 설문조사를 한 결과 대부분의 무용인들은 web에서 무용정보를 이용하는 것을 중요하다고 느끼고 있으나, 국내 web 무용정보가 부실하기 때문에 이용률이 저조했다. 따라서 본 연구에서는 국내 무용인들에게 보다 실질적이고 효과적인 무용정보 시스템을 구축하기 위한 기초 연구로 기존 국내 Web 무용정보를 분석하여 문제점과 개선점을 제시하였고, 실질적인 국내 무용인의 구체적인 정보요구를 파악하였다.

Visitors to a Web site leave access logs documenting their activity in the site. These access logs provide a valuable source of information about the visitors' access patterns in the Web site. In addition to the pages that the user visited, it is generally possible to discover the geographical locations of the visitors. Web servers also records other information such as the entry into the site, the URL, the used operating system and the browser, etc. There are several Web mining techniques to extract useful information from such information and visualization of a Web log is one of those techniques. This paper presents a technique as well as a case a study of visualizing a Web log.

Web services show a rapid evolution and integration to meet the increased users' requirements. Thus, web services undergo updates and may have performance degradation due to undetected faults in the updated versions. Due to these faults, many performances and regression anomalies in web services may occur in real-world scenarios. This paper proposed applying the deep learning model and innovative explainable framework to detect performance and regression anomalies in web services. This study indicated that upper bound and lower bound values in performance metrics provide us with the simple means to detect the performance and regression anomalies in updated versions of web services. The explainable deep learning method enabled us to decide the precise use of deep learning to detect performance and anomalies in web services. The evaluation results of the proposed approach showed us the detection of unusual behavior of web service. The proposed approach is efficient and straightforward in detecting regression anomalies in web services compared with the existing approaches.

Information system outsourcing induces firms to concentrate on the core competence and to improve business value by utilizing specialized information systems outsourcing vendors. However, for those strategic effects, the outsourced information systems should guarantee a certain service level. Now companies are considering to adopt SLA(Service Level Agreement) as a method to check the service level of the outsourced information systems in quantitative terms. On the contrary, customer satisfaction survey supports qualitative analysis, and helps companies to understand the qualitative effects on information system more systematically. Recently, the growing use of the internet makes customer satisfaction survey to be carried out on the web. For that reason, lots of researches related to web survey have been performed. But these researches are just focused on finding out only items to be measured and the effect of web survey. In this paper, based on the service quality research model for information system outsourcing, we formalize and propose a web survey process, a system architecture, and a functional structure for information system outsourcing customer satisfaction survey. Additionally, we provide the implementation results for the web survey systems.
