With development of mobile communications terminal and expansion of mobile Internet, a large number of users can use mobile web contents at anytime and anywhere and will demand service of greater contents. Due to such demand, many studies are being carried out on transcoding contents so that wired web contents can be used in mobile web. However, transcoding and creation of mobile web contents involve difficulties because specifications available from telecommunications companies and mobile terminals have not been standardized. Especially, in order for serving dynamic object of wired web page contents to dynamically change according to time or user, it is required not only to program scripts to suit each terminal, but also to transcode the resources used in advance. for solution to this problem, this study uses the hierarchy structure of DOM (document object model) to display structural characteristics of wired web page. In other words, this study proposes the following technique. Wired web pages are analyzed and the results are established as data structure. Then, dynamic object is extracted and the domain is indexed so that, when serving mobile web page, information can be extracted at the indexed position to create mobile web contents for service on real-time basis. Also, this study aims at developing an editing device to edit mobile web contents and mobile web service server to service the edited contents by applying the above technique.

웹 로그는 웹 서버를 통해 이루어지는 작업들에 관한 기록으로써, OLAP이나 데이터 마이닝과 같은 비즈니스 인텔리전스 기술로 분석되어 고부가가치 창출에 사용되는 중요한 자료이다. 웹 로그에는 파일 이름과 같은 물리적인 데이터가 저장되는데 이러한 데이터는 분석에 사용되기 전에 정제과정을 통해 의미 있는 데이터로 변환되거나 불필요한 경우에는 삭제된다. 웹 로그 데이터의 분량을 적정선으로 유지하면서 데이터 정제 작업의 일부가 해결되도록 하는 방법으로 웹로그 생성단계에서 시스템이 제공하는 필터를 쓸 수 있다. 그러나, 필터로는 웹 페이지의 내용이 동적으로 변경되는 경우 그 상황을 즉시 반영하기가 쉽지 않다. 본 연구에서는 웹 로그가 ‘지능적 웹 로거’를 통해 생성되도록 하여 이러한 문제를 해결하였다. ‘지능적 웹 로거’를 통해 불필요한 데이터의 생성을 막고, 물리적인 데이터를 신속하게 의미 있는 데이터로 변환하도록 하였다. 웹 페이지의 변경 내용을 웹 로그 생성에 즉시 반영하여 의미 있는 데이터 생성에 이용함으로써, 웹 로그 생성 후에 실행되던 데이터 정제작업 자체를 단순화시켰고, 웹사이트 관리자가 편리한 사용자 인터페이스로 로그 규칙을 만들어 적용할 수 있도록 하였다.

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.

The service providers of Internet have to work out a personalized contents service system focused on variety of customer's complex individuality. To effectively adopt individual customer's preference and actively adapt change of business situation, suppose an system of the service which emotional experience using emotional-based web design. In the experimental results, it is found that Internet service system implemented based on this idea is more effective than the existing systems in the view point of extension of customer's emotional satisfaction and visit duration time goes longer beyond that of the traditional systems.

One of the most important factor while developing web application is to separate presentation and business logic lowering the maintenance cost. There are various web application development tools mainly categorized as script based such as Servlet, JSP, ASP.NET techniques and dynamic server page development frameworks such as Struts, JSF (Java Server Faces), Spring MVC etc. These tools provide web tier processing solution but not the complete separation of presentation and business logic. In this paper, we developed custom tog component that separate presentation and business logic, to process them we also developed container. In addition, DOM tree is applied to the developed container to manage the presentation effectively.

인터넷 이용의 급속한 증가로 웹사이트의 증가뿐만 아니라 웹사이트 내의 웹 문서도 급속한 증가를 보이고 있다. 따라서 이를 효과적으로 사용자들에게 보여주기 위한 동적인 추천 시스템들이 많이 제안되고 있다. 그러나 이러한 추천 시스템들은 전체 사용자들의 브라우징 패턴이나 전체 웹 문서들의 연관성만을 고려하여 서비스를 제공함으로써 개인 사용자들의 관심도를 고려하지 않은 문제점이 있다. 이에 본 논문에서는 웹사이트에 남게되는 로그파일의 분석을 이용한 사용자별 브라우징 패턴과 웹 페이지의 액세스 타임의 측정을 통해, 사용자의 관심도를 측정한다. 그리고 이를 바탕으로 웹 문서들에 대해서 퍼지개념을 적용한 자동분류 알고리즘을 이용하여 사용자의 관심도가 반영된 선별된 웹 문서를 자동분류 및 선별하여 보여줄 수 있는 방안을 제시한다.

Deep web collection means entering a query in a search form and collecting response results. It is estimated that the information possessed by the deep web has about 450 to 550 times more information than the statically constructed surface web. The static method does not show the changed information until the web page is refreshed, but the dynamic web page method updates the necessary information in real time and provides real-time information without reloading the web page, but crawler has difficulty accessing the updated information. Therefore, there is a need for a way to automatically collect information on these deep webs using a crawler. Therefore, this paper proposes a method of utilizing scripts as general links, and for this purpose, an algorithm that can utilize client scripts like regular URLs is proposed and experimented. The proposed algorithm focused on collecting web information by menu navigation and script execution instead of the usual method of entering data into search forms.

Web apps have a problem that they cause same data to be repetitively retrieved, processed, and displayed when web browsers load different web pages. To resolve the problem, this paper presents and evaluates a new method for restructuring of Java web apps. This approach dynamically analyzes Java web apps from the MVC (Model-View-Controller) architecture point of view and identifies redundant data by using the composite view pattern. Then the input apps are restructured in order not to load the redundant data when users make requests for new pages. This restructuring generates new web apps that conform to the MVC architecture and improve the performance of input web apps. The experimental results showed that when compared to legacy web apps, the restructured apps' response time was reduced on desktop PCs and mobile devices by 38% and 55%, respectively. In addition, case studies using open-source web apps showed the applicability of the proposed approach.

Web pages in a template-based web application (TWA) are automatically populated using a template shared by the pages with contents specific to the pages. So users can easily obtain information guided by a consistent structure of the template. Reduced duplicated code helps to increase the level of maintainability as well. However, TWA still has the interaction problem of classic web applications that each time a user clicks a hyperlink a new page is loaded, although a partial update of the page is desirable. This paper proposes a reengineering technique to transform the multi-page structure of legacy Java-based TWA to a single page one with partial page refresh. In this approach, hyperlinks in HTML code are refactored to AJAX-enabled event handlers to achieve the single page structure. In addition, JSP and Servlet code is transformed in order not to send data unnecessary for the partial update. The new single page consists of individual components that are updateable independently when interacting with a user. Therefore, our approach can improve interactivity and responsiveness towards a user while reducing CPU and network usage. The measurement of our technique applied to a typical TWA shows that our technique improves the response time of user requests over the TWA in the range from 1 to 87%.
