Because the complexity in the development phase of geographic information system, its hard to change its operation or user interface after the development. So we should develop most part of the applied GIS even though previous GIS is almost exist. In other words, reusing the previous system is not easy. Therefore, its required to research reusable GIS for easy construction of applied GIS. This thesis describes design and implementation of web GIS framework which makes applied web GIS development more easy. Framework is software library composed of reusable units such like classes and objects. Proposed web GIS framework Provides basic web GIS functionalities and execution design to web GIS developers. They could extend the framework to build applied web GIS with applied operation and user interface. The development of applied web GIS could be archived by various tools used for general web application development.

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.

The purpose of this study is to construct e-Nonsan, a user friendly river quality management information system for Nonsan-si basin using GIS (geographical information system) technology. GIS was ideally suited featuring a geographical characteristics(e.g., industries, cattle sheds) and very effectively used in mapping and symbolization for the distribution of the spatial/periodic status(e.g., pie or column chart) of the point/non-point pollutant source loads which can be effectively applied to a information system on the web-site. And a user interface, GUI(graphic user interface) was designed very diversely and simply enabled the and non environmental experts connect with the system and obtain a useful information of river quality. e-Nonsan, a visual mapping system for river quality was developed by reframing the monitoring data as graphic symbols and it was ideally suited to exploring area-wide river quality at a user-friendly manner due to extensibility and scalability along the various survey points. Eventually the final step of this study was to construct e-Nonsan based on Web-GIS could be assessed anywhere if internet service is available and offer a very useful information services of the river quality to the publics.

The purpose of the study is to analyze web-site content for activating internet apparel shopping malls. With a view to improving the transaction experience and efficiency for both shopping-mall managers and customers. According to RANKEY(rankey.com) and 100 HOT RANHNC(100hot.co.kr), 5 big internet apparel shopping malls were chosen, divided into 3 web-site criteria of Users' Interface Section, Informational Section, and Customer Satisfaction Section, and analyzed. The results of our analysis of the web-site contents are as follows: 1) Concerning Users' Interface Section, the structure of the first screen is complicated and confusing. 2) Concerning Informational Section, the specific image of shopping man is ambiguous to understand and differentiated product information is not properly given. 3) Concerning Customer Satisfaction Section, the customers are not encouraged to show any interest in the shopping mall. These three problems are easily observed in most of the internet apparel shopping malls. To develop the internet apparel shopping mall, the following methods to activate them need to be implemented.

Nowadays, we can easily access a remote database as well as a local database with HTML forms. Although implementing a database application with HTML forms is much simpler than implementing it with a proprietary graphical user Interface system, HTML forms and CGI programs still must be coded. We implemented a software tool that automatically generates the SQL statements that create a database for an application, the forms that are used as a user interface, and the Java servlets that retrieve the data requested through the forms. The database tables to be treated and the forms to be generated are determined by the class diagram for the application. Our software tool, which we call WebSiteGen, thus simplifies the implementation of a Web-based database application.

Since simple and convenient user interface, the Web is diffused widely. For integrating Web as a view of user interface and CORBA, CORBA object is made in applet, which is sent to Web browser in Client and executes by Web browser. To use CORBA Event Service in Web without violating a security constrains of applet, we need a interoperability of Event Service. This paper investigates interoperability of event channels of the event service of CORBA. We present three different methods that make one event channel. Pros and cons of each method are described. All mentioned approaches have been implemented in Java. An experimental performance evaluation has been carried out and evaluation results are also given.

The nowaday Internet reached in phase that collect ideas of netizens through the Internet now regularly according as offer netizens great many information. In these circumstance, web survey system knows off-line just in on-line the value more do can. However, because participations of many people are important, web survey must be subject that can attract interest of people, and more visual function sees that can lead high hailing degree in active interest and survey more than netizen by offering new interface that provoke interest because is added than uninteresting screen. Therefore, I wish to enhance value still more by doing as can do survey interestingly using web survey system that use flash.

In this paper, we introduce a web-based system that leverages the capabilities of the ρ(rho)-algorithm, which is a Structure Information Control Net (SICN)-oriented process mining algorithm, with open-source platforms, including Django, Graphviz, and Cytoscape, to facilitate the rediscovery and visualization of business process models. Our approach involves discovering SICN-oriented process models from process instances from the IEEE XESformatted process enactment event logs dataset. This discovering process is facilitated by the ρ-algorithm, and visualization output is transformed into either a JSON or DOT formatted file, catering to the compatibility requirements of Cytoscape or Graphviz, respectively. The proposed system utilizes the robust Django platform, which enables the creation of a userfriendly web interface. This interface offers a clear, concise, modern, and interactive visualization of the rediscovered business processes, fostering an intuitive exploration experience. The experiment conducted on our proposed web-based process discovery system demonstrates its ability and efficiency showing that the system is a valuable tool for discovering business process models from process event logs. Its development not only contributes to the advancement of process mining but also serves as an educational resource. Readers, students, and practitioners interested in process mining can leverage this system as a completely free process miner to gain hands-on experience in rediscovering and visualizing process models from event logs.

This paper examines users' emotion from both 2D and 3D web interfaces and finds their differences. First, 77 words representing users' emotion were collected from the previous research papers. Second, a web survey system was developed using these collected words and prepared 3 web interface prototypes to collect users' emotions from different types of web interfaces. Finally, a web survey was conducted and its results were analyzed. The result of the survey showed that there were emotional words that were commonly experienced from either 2D or 3D web interfaces. However, it also showed that there were emotional differences between 2D and 3D web interface; 3D web interfaces provide users with specific emotional experiences because of their own characteristics - depth and dynamic movement. It is believed that the words collected from the survey could be the criteria to evaluate the quality of the 3D web interfaces and encourage the research on users' emotion from 3D interfaces.

Both browsing and retrieval with search engines are major operations that establish the interaction between users and the Web. Although both operations are usually combined to locate information from the Web, recent growth of the Web has overtaken the potential of this conventional interaction. This paper proposes the concept of Retrieve, Browse, and Analyze (RBA)-based interactions, as the improvement of the conventional Retrieve and Browse (RB)-based interaction. The prototype interface based on RBA-based interaction is also presented.
