In this study in order to verify the overall information seeking behavior of the Web-based OPAC users, it was analyzed transaction log file for 7 years. Regarding Web-based OPAC information seeking behavior, it was studied from the perspective of information seeking strategy and information seeking failure. In search strategy, it was analyzed search type, search options, Boolean operator, length of search text, number of uses of word, number of use Web-based OPAC, number of use by time, by week day. Also, in search failure, search failure ratio, search failure ratio by search options, search failure ratio by Boolean operator were analyzed. The result of this study is expected to be utilized for OPAC system and service improvement in the future.

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.

This study aims to investigate characteristics of most clicked documents of Naver's universal search service. In particular, this study analyzed characteristics of most clicked documents such as click ratio, collection distribution, and yearly distribution. Also, clicked documents were evaluated in terms of relevance, credibility, and currency. In conducting this study, query logs and click logs of unified search service were analyzed. The results of this study show that most clicks occurred in blog collection and average click concentration rate reached almost 50%. Also, the relevance and currency of most clicked documents were quite high, but credibility of these documents were on average level. The results of this study can be implemented to the portal's effective development of searching algorithm and interface.

The purpose of this study is to identify possible needs for system improvements and reflect them on the operation and development of the system as a result of the usability assessment of an information site in science and technology. For this study, a variety of data collection techniques, including search logs, interviews, and think-alouds, were used. The search log data was processed to quantify four evaluation aspects, which were the effectiveness, efficiency, satisfaction, and errors. The verbal data collected by think-alouds and post-interviews were used to identify possible needs of enhancement in a qualitative analysis. The comparison of the usability before and after the system enhancement revealed an increase of 15 points for effectiveness, 35 seconds decrease in efficiency, 5 points increase in satisfaction, and 1.1 errors decreased, implying an overall improvement of the usability of the current system.

본 논문에서는 웹 사이트에 접근하는 이용자의 패턴을 분석하여 정보 제공이 보다 용이한 구조로 자동 개선시켜 나가는 적응형 웹 사이트의 구현 방안을 제시한다. 특히, 본 연구에서는 기존 웹 사이트의 구조를 가능한 파괴하지 않는 범위 내에서 웹 사이트론 변경하고자 이용자의 접근 패턴상 연관성은 높으나 접근 경로가 긴 문서들을 추출하여 색인 페이지를 추가 생성한다. 이를 위하여, 먼저 대용량의 웹 서버 로그 데이터를 대상으로 하이퍼 링크 구조에 따라 필터링된 최후 전진 문서만을 가지고 데이터 시퀀스를 구성한다. 이러한 데이터 시퀀스에 새로운 순차 접근 패턴 탐색 알고리즘인 TPA를 적용함으로써 웹 문서간 충분한 지지도를 갖는 연관성 있는 문서들의 시퀀스를 구한다. 이와같은 빈발 시퀀스들에 대한 색인 페이지를 추가로 생성시켜주는 서비스를 통하여 이용자들의 효과적인 정보 접근을 지원할 수 있는 웹 사이트로의 변경이 가능하다.

인터넷이 확산과 더불어 보안의 문제도 증가하고 있다. 이로 인해 네트워크 보안과 서비스에 대한 관리자의 책임 또한 더욱더 중요시 되고 있다. 본 논문에서는 웹로그를 분석하여 웹호스팅 환경에서 장시간 사용되지 않아 보안성이 약한 사용자 계정을 관리자로 하여금 시스템 보안의 틈새를 찾고 이를 해결할 수 있는 방안을 제시하였다. 이를 위해 WLA(Web Log Analyzer)를 구현하여 웹서버가 수행될 때 기록되는 각각의 로그를 분석한다. 그 결과 웹호스팅을 사용한 계정 이름의 수를 포함한 UUL(Used User List)를 구축하고 일정기간 사용하지 않는 호스팅 서비스 이용자를 찾아내고, 관리할 수 있게 한다.

최근 기업에서의 인터넷 응용이 보편화되고 있으며, 인터넷 기반의 전자상거래(CALS/EC)는 선택의 문제가 아니라 생존의 수단으로 받아 들여 지고 있다. CALS/EC는 비즈니스 관련 정보를 전자적으로 교환함으로써 기존의 비즈니스 방식을 개선, 전환, 재정의하고, 비용절감, 품질향상, 서비스의 품질과 속도개선을 통해 고객만족과 기업이윤을 증대시키는 새로운 기업의 전술로 정의되고 있다. 이러한 인터넷 기반 CALS/EC의 활성화로 인해 여러 분야에서의 기업 상품에 대한 마케팅 전략 등이 최우선적으로 고려되고 있다. 본 논문에서는 이러한 전자상거래를 포함, 인터넷 이용자의 특성.취향을 분석하기 위한 이용자 특성.취향 분석 시스템의 구성원리와 그 구성요소 중 하나의 모듈인 특성화된 이용자 로그정보로부터 추적 알고리즘을 이용한 시뮬레이션을 수행함으로써, 보다 정확한 이용자 정보를 수집하여 유연성있는 정보를 제공할 수 있는 시스템을 구축하고 구현하였다.

With the perspective of information management, on-going monitoring of the specified service function is one of the major activities and even critical process. The research consisted of three empirical research questions such as, the current usage and overall user-satisfaction, the quality of the R&D information content and the service, and the problems which have been observed by the actual user group of National Digital Science Library (NDSL). The results of the investigation provided several guidelines that can be utilized for the improvements of the R&D information user service as well as some recommendations for overall optimal administration.

As the users' information use environment changes to the Web, the archives are providing more services on the Web than before. This study analyzes the users' recent inflow route and the highly ranked 100 search terms of each month for 10 and half years in the Web site of National Archives of Korea, and suggests suitable information services. As a result of the analysis, it was found out that the inflow route could be divided into access from portal site, by country, from related institutions, and via mobile platform. As a result of analyzing the search terms of users for the last 10 and half years, the most frequently searched term turned out to be 'Land Survey Register', which was also the search term that was searched for with steady interests for 10 and half years. Also, other government documents or official gazettes were of great interests to users. As results of identifying the most frequently searched and steadily searched terms, we were able to categorize the search terms largely in terms of land, Japanese colonial period, the Korean war and relationship of North Korea and South Korea, and records management and use. Based on the results of the analysis, we suggested strengthening connection of the National Archives Web site with portal sites and mobile, and upgrading and improving search services of the National Archives. This study confirmed that the analysis of Web log and user search terms would yield meaningful results that could enhance the user services in archives.
