One of the key success factors for the intelligent IT service which is characterized by personalization and automation, is to obtain relevant data from either sensors or data storage for reasoning, analyzing and forecasting. The availability of the open data sources such as public portal sites remarkably increases the efficiency and quality of the intelligent IT service. However, with the condition that not all data in the existing public or private sites are opened or have various types of openness, it prohibits the value of utilization. For these reasons, it is highly required to evaluate the extent of openness of data storage. However, there are only a few studies which explore the factors which affect the degree of data openness with respect to intelligent IT services. Hence, this study aims to propose an evaluation model including the indices to evaluate a process of opening data for the intelligent IT service from a viewpoint of data utilization process. The indices are applied to evaluate the actual multinational websites, which provide public data for verification. We also discuss the implications of the evaluation according to the results.

The purpose of this study is to implement evaluation on domestic cyber University web site to analyze web usability and web accessibility in order to present how much cyber University provides various personalized services and qualitative contents to users on web site. And also with this result, I hope to contribute in qualitative development of web site and reliability of remote education. For this purpose, I developed checklist suitable to remote University by applying SM-ABCDE assessment method of Moonhyeongnam, the professor in Sookmyung Women's University, and implemented evaluation on web sites of 17 cyber University over the five aspects of attraction, business, contents, design, and engineering. As the result of this study, it was found that Busan Digital University was best in the respect of attraction, both Kyunghee Cyber University and Cyber University of foreign studies were best in the respect of business, Kyunghee University was best in the respect of contents, and Hanyang Cyber University was best in the respect of design. It was also evaluated in the comprehensive view and the order was found that Kyunghee Cyber University, Busan Cyber University, and Hanyang Cyber University. However in the respect of engineering, it came out that all the sites did not observe the regulation on web accessibility. If domestic Cyber Universities are to observe the regulation on web accessibility with the long term view, on the base of this study, web usability would be increasing. Then they can secure various classes of customers as well as ordinary people so that they will be able to take the real place of educational institution orienting the most advanced educational method in the society of knowledge and information in addition to advance in themselves.

The purpose of this study was to develop a methodology of user participation evaluation of a scholarly information site in the field of science and technology and to enhance the site by applying a set of testing protocols. Experiments were conducted in a laboratory setting. Data from multiple sources, including eyetracking, search logs and post surveys, were collected and analyzed quantitatively. Based on the results of eyetracking, the contents and images were reorganized after removing unessential elements in the site. The resulting data from the search logs showed that the users were able to finish the tasks more quickly with the revised user interface. The results of the data analysis of post surveys indicated an overall improvement in the revised website compared to the original one.

Following the increase in the supply of smartphones and the increase in the use of wireless Internet, the online shopping environment is also changing into mobile shopping. However, the domestic mobile shopping services fall short of people's expectations compared to desktop Internet shopping malls. These are mainly due to the restricted screen size and inconvenient data entry of mobile devices, the slow Internet speed, and other restrictive conditions. Accordingly, in this paper, the usability of three main domestic mobile shopping malls was evaluated using a heuristic evaluation method. The factors that must be considered when producing a mobile website, the consideration for the mobile users, and the main functions of a shopping mall, were considered to define an evaluation form. The results of the evaluation were then analyzed to propose the problems of mobile shopping malls and the directions for their improvement.

The objective of this research is to measure the quality of web accessibility of Tripitaka Koreana websites. To achieve this research aim, three typical websites were selected, and conducted both the system-based evaluation and the user-based evaluation using the six common indicators. It found that no website satisfied with the 95% accessibility level in all six indicators, and users were more likely to respond positively to the high level of web accessibility results from the system-based evaluation (i.e., providing alternate texts, providing titles, displaying the basic languages, performing user requests, and providing labels). We suggested some ideas to increase the web accessibility based on the results of analysis.

Web-accessibility evaluation tools can be used to determine whether or not a website meets accessibility guidelines. As such, many such tools have been developed for web accessibility, but most of them dynamically fetch and analyze pages and as a result, some pages maybe omitted due to the lack of access authorization or environment information. In this paper, we propose a static method that analyzes web accessibility via abstract parsing. Our abstract parsing technique understands syntactic and semantic program structures that dynamically generate web pages according to external inputs and parameters. The static method performs its analysis without omitting any pages because it covers all execution paths. We performed an experiment with a PHP-based website to demonstrate how our tool discovers more accessibility errors than a dynamic page accessibility analysis tool.

Because the web sites are in common today, the access to the web for disabled people and old aging people, what we call accessibility, becomes more important. Even though efforts to reduce the informational gap resulted from the lack of the accessibility have been carried out, the studies in this field in Korea are not still in popular. In this study, previous research on the measurements for the accessibility is reviewed and then a new model measuring accessibility is suggested. To increase the validity of the measurement, both an automated tool and a manual test are employed. First we used the 'A-Prompt', one of the popular automated validation tools and analyzed web sources, and applied manual tests by HPR Screen Reader. With the error rates calculated, the accessibility of the government web sites between Korea and the United States was compared and finally the conclusions were drawn.

As of 2022, the number of Internet sites for public institutions registered on the 'Government 24' website (www.gov.kr) of the Ministry of the Interior and Safety is 17,000. The direct transfer takes a lot of human and material resources and time between the records-producing institution and the records-management institution that manages websites as records. In addition, it is practically difficult for records management institutions to migrate and operate various software and application technologies required to run each website. A method of automatically collecting websites from a remote location using web crawler software is used domestically and abroad to overcome these practical limitations. This study compared the performance of the web crawler required to collect and manage public Internet websites as records remotely. The most suitable web crawler was selected through a step-by-step review of several web crawlers from previous studies and other literature. Several public agency websites were applied to compare the actual performance of the crawlers in the evaluation process. The study provides empirical and specific performance comparison information for organizations that need to choose a web crawler.
