  • 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.

  • Purpose: This study was conducted to analyze web sites that provide child-care information and to provide a proper model for child-care web sites. Method: The evaluation tool with 23 items including purpose, contents, timeliness and reliability, interaction, and function was developed and modified. Quantitative analyses of 48 web sites, which were selected using popular search engines, were done. Result: 1) The aim of the web site was clearly shown for 24 sites (63.2%) and 17 sites (44.7%) provided the information for judging whether the informant was an expert. 2) Most web sites provided information on feeding, nutrition, and common health problems, and 11 sites provided information on care of problem behavior, but only 6 sites provided information on mother-infant interaction. 3) Timely information was provided on 21 sites, however none of the sites provided information sources. 4) Methods for contact the authors were found for 31 sites (81.6%) and 19 sites (50%) had active bulletin boards to receive opinions from users. 5) There were 32 sites where information could be found by clicking less than 3 times. Conclusion: We suggest that the evaluation criteria for child-care web sites used in this study is a tool that can be used to evaluate web sites with consistency, but there is a need for further study to develop standardization of the evaluating tool.

  • 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 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.

  • This paper proposes a mathematical model for web site service quality evaluation, which first applies analytic hierarchy process(AHP) to determine the weights of evaluation indexes of web site service quality and then analyzes web site service synthetically by means of fuzzy methodology. In this case, experts' knowledge cannot only be used but its subjective component can be eliminated. Hence, the web site service quality can be analyzed and evaluated more reasonably. After establishing this model, the experiment results will be given, which verify the feasibility and validity of the proposed model. The model proposed here is very simple and easy to implement and can provide a useful way to help developers evaluate their web site service quality efficiently.

  • Evaluation of retrieval systems is mostly limited to laboratory settings and rarely considers changes of performance over time. This article presents an evaluation of retrieval systems for internal Web site search systems between the years 2006 and 2011. A holistic evaluation methodology for real Web sites was developed which includes tests for functionality, search quality, and user interaction. Among other sites, one set of 20 Web site search systems was evaluated three times in different years and no substantial improvement could be shown. It is surprising that the communication between site and user still leads to very poor results in many cases. Overall, the quality of these search systems could be improved, and several areas for improvement are apparent from our evaluation. For a comparison, Google’s site search function was also tested with the same tasks.

  • With a swift development of information technology, web sites get more important roles as user's living places. This quantitative and qualitative expansion of web sites requires the need for an evaluation framework of web sites from comprehensive perspectives. This study proposes two dimensions for web site categorization and three dimensions for web site evaluation. These dimensions were developed based on the architectural perspectives that have been used to evaluate buildings in the real world for more than a thousand years. First, in order to categorize various web sites, we extracted two dimensions, user's goals and user's behaviors from behavioral architect which approaches user's behaviors in designing buildings. Second, in order to evaluate four web sites groups, we suggested three dimensions, which are firmness, commodity, delight used in evaluating buildings in the real world. Then for each of the four different web sites groups an empirical survey was conducted to verify these three dimensions of architectural metrics. This ends with study implications and limitations.
