  • This research is carried out being divided into a first evaluation and second evaluation. A Study is carried out on first, the accessibility compliance level of Korea government department websites and second, whether the site which complies well with web accessibility increases web usability for users through a web usability evaluation. The evaluation result, web sites which comply well with the web accessibility guidelines were observed to increase web usability for both normal and disabled people but web sites which do not comply well were observed to lower the web usability making the web sites unavailable or inconvenient to use. Therefore, it can be concluded that there is a very close interrelationship between web accessibility and usability and thus compliance with web accessibility is not an option but a mandatory requirement.

  • Web-based services have fundamentally confidential problems due to characteristics of internet environment such as anonymity. These problems are serious obstacles to grow the web-based services. The security and confidence of web-based services rely on both service provider and users' opinion. But the former has difficulty in trusting the service provider and the latter takes too long time to propagete all users after converging their opinion. Therefore it is necessary to establish the objective and confidential evaluation and certification program for web-based service. In this paper, the internal and external web-based services evaluation and certification programs are compared and analyzed. The critical factors and evaluation methodology for secure and confidential web-based service are identified. Finally, this paper provides the improvement and strategy for web-based services evaluation and certification program.

  • The purpose of this study is to suggest the shortcomings and the direction of the web accessibility evaluation studies by analyzing the research trends on web accessibility evaluation in Korea. For this aim, a total of 59 theses presented in the registered academic journal and the candidate of registration academic journals from January 2000 to March 2017 were selected. The selected dissertations have been analyzed based on the evaluators, the evaluation targets, the evaluation methods, and the evaluation results with regard to web accessibility. As a result of the analysis, the highest rate in the evaluator aspect was 'independent evaluation (66 percent)' and the highest percentage in the evaluation target aspect was 'web site (83 percent)'. When it came to the evaluation methods, automatic evaluation and the mixture of automatic evaluation and manual evaluation had a similar percentage. Lastly, only two papers showed that web accessibility did not have any problems. This study is meaningful in the sense that it suggested a desirable direction for the web accessibility studies in Korea and web accessibility evaluation studies in the situation when the meta studies which analyzed research trends are insufficient.

  • In this study, we investigated web contents accessibility of 60 hospital web sites in Korea. The eight evaluation criteria were used for estimating the web contents accessibility of the web sites. These criteria were as follows: providing an alternative text, providing caption for moving picture, providing a skip navigation, usage of pop-up windows, usage of a summary or a caption tag for data table, providing a page title, providing a label for online form, and usage of java scripts. K-WAH 3.0 was used for estimating five evaluation criteria. According to Internet web contents accessibility guideline 1.0, we estimated the rest three evaluation criteria manually and described good or bad examples for the evaluation results technically. The results show that the web accessibility of hospital web sites is generally insufficient and the constant interests in improvement for accessibility are urgently needed.

  • Understanding the importance of web accessibility as the solution for digital divide, this study recognizes the problem that existing web accessibility researches have been conducted only by governmental administrative organizations and the accessibility researches of web service that is frequently used in every day life are rare. For the research on the actual condition of web-accessability, this study selected the e-mail service of the representative web-service providers - Daum, Naver, and Empas. Through this evaluation research, this study is intended to present a way to provide convenient and efficient service for those who have been alienated from information. For the accessibility evaluation, the automation evaluation tool "KADO-WAH 2.0" was used. And then, source analysis and manual evaluation using Firefox were conducted to see if 'web contents accessibility guideline 1.0' had been kept.

  • This paper proposes a method for evaluating web pages by considering implicit user reaction on web pages. Usually users spend more time and make more reactions, such as clicking, dragging and scrolling, while reading interesting pages. Based on this observation, a web page evaluation method by observing implicit user reaction is proposed. The system is designed with Ajax for observing user reactions, and neural networks for learning correlation between user reactions and usefulness of pages. The amounts of each type of user reactions are inputted to neural networks. Also the numbers of characters and images of pages are used as inputs because the amount of users' behaviors has a tendency to increase as the length of pages increase. The experiment is conducted with 113 people and 74 pages. Each page is ranked by users with a questionnaire. The proposed method shows more close ranking results to the user ranks than Google. That is, our system evaluates web pages more closely to users' viewpoint than Google. Although our experiment is limited, our result shows powerful potential of new element for web page evaluation. Some approaches evaluate web pages with their contents and some evaluate web pages with structural attributes, particularly links, of pages. Web page evaluation is for users, so the best evaluation can be done by users themselves. So, user feedback is one of the most important factors for web page evaluation. This paper proposes a new method which reflects user feedbacks on web pages.

  • A fundamental issue to consider when searching Web information is the quality of information itself and of service. If a Quality Information System (QIS) of Digital Library is sought, new measurement criteria and evaluation index for Web information service are required. Reliance on the existing evaluation criteria is not acceptable if data retrieved are not information and the service is only noise to end-user. Applying existing evaluation criteria of online database to Environmental & Energy Engineering Web DB revealed the limitations and provided a practical and case-based information for improvement. No attempt was made to survey comprehensively all of the evaluation methods that could possibly be relevant. Instead, this discussion concentrates on the information service evaluation index being developed in the KDPC Project. The research found that domestic Web-DB service are still woefully insufficient to conduct comprehensive investigations on environmental topics. More qualified and specialized R&D Web information service and the development of new evaluation criteria based on this investigation(research I.) will be discussed in follow-up research II.
