In this paper, we present the development of a system(WebPierrot) that helps end-users to generate home pages with the construction of their corresponding web databases without the web programming technique. It consists of a page editor. a database wizard and a database manager. The page editor creates and modifies multimedia home pages. The database wizard generates databases operated with home pages automatically, and the database manager maintains the database related to the home pages. The page editor has been made based on the DHTML(Dynamic Hypertext Markup Language) and lets users generate multimedia home pages interactively. The database manager creates, updates and manages web databases. The system has the advantage which end-users can create multimedia home pages containing databases without requiring web database programming.

Web designers generally use a story board, a site map, a flow chart or the combination of these for representing web sites. But these methods are difficult to represent the entire architecture of a web site, and may be not adaptive for describing the detail flow of web pages. To solve these problems to some degree, there were works using EMFG(Extended Mark Flow Graph) recently. However the conventional EMFG representation method is not adaptive to represent the dynamic interface of web sites because that cover only the static parts of a web site. Internet utilization is rapidly growing in our life and we cannot imagine the worlds of work, study and business without internet. And web sites recently have not only more complex and various architecture but also web pages containing the dynamic interface. Therefore we propose the representation method of these web sites - for example, a web site containing varying pages with time and varying page status or contents with mouse operations - using EMFG. We expect our work to be help the design and maintenance of web sites.

Recently, various web page development tools for both the beginner and the experienced user are introduced. These tools allow them to generate web pages easily and quickly. However the web pages generated by the tools have lots of functional limitations. Generally authors must have much knowledge for web authoring tools, HTML, CGI programming to open web sites for special purpose. Especially, most of the lecture supporting web site necessarily requires much effort to construct it as well as special functions using CGI, Javascript, Java Applet, etc. to generate dynamic web pages. In order to solve above mentioned limitations, we design and implement an automatic web site construction system using RASIS based on remote execution technologies.

The dynamic nature and exponential growth of the World Wide Web remain crawling important pages early still challenging. State-of-the-art crawl scheduling algorithms require huge running time to prioritize web pages during crawling. In this research, we proposed crawl scheduling algorithms that are not only fast but also download important pages early. The algorithms give high importance to some specific pages those have good linkages such as inlinks from different domains or host. The proposed algorithms were experimented on publically available large datasets. The results of experiments showed that propagating more importance to the inter-host links improves the effectiveness of crawl scheduling than the current state-of-the-art crawl scheduling algorithms.

While the WWW offers an incredibly rich base of information, organized as a hypertext, it does not provide a uniform and efficient way to retrieve specific information. When one tries to find information entering several query terms into a search engine, the highly-ranked pages in the result usually contain many irrelevant or useless pages. The problem is that single-term queries do not contain sufficient information to specify exactly which web pages are needed by the user. The purpose of this paper is to describe the employment of association rules in data mining for developing networks and computing associative coefficient among the terms. And this paper shows how the dynamic query expansion and/or reduction can be performed in information retrieval.

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.

본 논문에서는 현재 웹의 주요한 기술로 부각되고 있는 액티브 서버페이지와 동적 웹 기술을 이용한 가상교육 시스템 구현에 대해서 다룬다. 이 시스템은 사용자로부터 프로그램 소스를 보호할 수 있고 또한 인터넷 서버에서 실행되는 액티브 서버 기술을 동적 웹 기술과 접목하여 사용자를 인지, 구별하고 사용자의 정보에 적합한 웹 페이지를 구성할 수 있다. 또한 가상교육시스템은 학년, 학과, 수강신청 정보에 따라서 적합한 사용자 환경을 구성하여 주고 수업진도에 따라 교안 및 정보를 제공할 수 있다. 이렇게 구성함으로써 시스템의 접속 사용자에 관련된 적합한 정보를 제공하여 사용자가 원하는 교육서비스를 받을 수 있게 한다.Abstract In this paper, we present our implementation of cyber education system using Dynamic Web and Active Server Pages, key technologies of the current web. This system is composed of web pages fitted to user information, which is collected and differentiated by both Active Server Technology running at server and protecting program source and Dynamic Web Technology. This system provides information and teaching content according to the progress of a course and user environments based on information such as a school year, a department and credit request information. Therefore login users can receive education services by providing adequate information related to them.

A web crawler is used widely in a variety of Internet applications such as search engines. As the Internet continues to grow, high performance web crawlers become more essential. Crawl scheduling which manages the allocation of web pages to each process for downloading documents is one of the important issues. In this paper, we identify issues that are important and challenging in the crawl scheduling. To address the issues, we propose a dynamic owl scheduling framework and subsequently a system architecture for a web crawler subject to the framework. This paper presents the architecture of a web crawler with dynamic scheduling support. The result of our preliminary performance evaluation made to the proposed crawler architecture is also presented.

In this paper, we suggest a kernel level multi thread web accelerator (called the SCALA-AX), which significantly improves the performance of the web soerver. In comparison with a conventional proxy web cache that is generally called a caching server and a simple content-copy based system, the primary functions and goals of SCALA-AX are designed to maximize the content services of a front end web server with high performance. Specifically, the SCALA-AX runs on the kernel level of a web sorrel, based on the newest caching techniques. Moreover, the SCALA-AX supports the http 1.1 protocol and allows the dynamic pages as well as static pages to be processed.
