Most web portals provide a web directory service which selects and classifies web sites according to their subject matter. In order to investigate the directory access behavior of general Korean web users, this study analyzes directory access logs of NAVER, a major Korean web search engine. This study suggests a methodology to classify the total sessions into six different session types. This study also discusses directory access behaviors of the NAVER users by examining the distribution of sessions according to session types, the lengths of navigation within a session, and the most frequently visited categories. It is expected that this study could contribute to the development of more effective web directory services.

The purpose of this study is to design the meta search system and the curriculum-oriented directory system for youth in science and to prove the efficiency of the systems through evaluating the usability. To attain the purpose of this study, both of the quality and quantity research method were used and questionnaire, interview. observation, thinking aloud method were used to collect a data for research. The result of this study is that the meta search system supplying convenient information use environment about the distributed information sources has higher usability than the individual search system. And the curriculum-oriented directory system supplying accessibility related with the class has higher usability than the subject-oriented directory system.

This study was investigated to the geography services and geographical directories through Internet in order to develop a geographical directory. Research method was the examination of different type of geography services through internet and geographical directories on the Internet search engines. The results show principles for a geographical directory construction: use both geographical names and subject names on the initial directory screen, repeated use the names through directory hierarchy, locality use on bottom directory as a geographical name, and fit use of the number of directories.

The purpose of this study is to develop the classification scheme in subject-based directory search engine for educational research information on the web. Five classification systems. Yahoo Korea, Argus Clearinghouse, DDC, ERIC thesaurus and KEDI thesaurus were measured in terms of coverage of subject fields, system logic, accuracy of terminology and efficiency of searching. For the design of Classification Scheme, this study considered the content of subject areas, features of information resources and efficiency based on users. Finally, the Classification Scheme was established in terms of 16 main divisions and 47 sub-divisions in educational research information.

일반적으로 비즈니스를 위한 기초자료를 말하며, 전통적인 방법으로 지금껏 해오던 두툼한 편람류나 디렉토리집 등을 장서꽂이속에서 열람하던 그런 모양새에서 벗어나 출판류보다 자료갱신이 빨리되면서도 비교적 손쉽게 찾고자 하는 업체에 관한 정보를 섞어서 열람하는 방식의 정보검색을 기업관련 데이터베이스 활용이라 할 것이다. 본고에서는 이와같은 국내외의 데이터베이스를 검색하여 보고자 한다.

개인화 서비스를 효과적으로 제공하기 위하여 사용자의 관심사를 이해하는 것은 매우 중요하다. 최근 많은 연구들이 사용자의 관심사를 이해하기 위하여 오픈 디렉토리 프로젝트를 이용하여 그 관심사를 주제별로 분류하는 방법을 제안하였다. 본 논문에서는 사용자의 관심사를 더욱 정확하게 이해하기 위하여 명사로 표현되어 있는 오픈 디렉토리 프로젝트를 동사 레벨로 확장하는 기법을 제안한다. 또한 실험 결과를 통하여 제안된 기법이 디렉토리와 연관된 동사를 효과적으로 확장하였음을 입증한다. 확장된 오픈 디렉토리 프로젝트는 사용자의 관심사를 동사 레벨로 이해하도록 함으로써 다양한 개인화 서비스에 활용될 것이다.

The study measured whether two search engines retrieve different Web documents for 6 queries. Two different search engines, Alta Vista in terms of keyword search engines and Yahoo in terms of subject directory engines were measured using as criteria, total number of documents retrieved, total number of relevant documents retrieved, recall and precision ratios. In addition, Alta Vista was suitable for specific and technical terms, while Yahoo was effective for general and plain terms. However, more elaborate research needs to be tested in terms of query characteristics.

In indexing and organizing Web resources, there have been two basic methods: automatic indexing by extracting key words and library classification schemes or subject directories of search engines. But, both methods have failed to satisfy the user's information needs, due to the lack of standard criteria and the irrationality of its structural system. In this paper I have examined the limits of library classification scheme's structures and the problems related to the nature of Web resources such as specificity and exhaustivity. I have also attempted to explain the logicality of Web resources organization by facet analysis and its strengths and limitations. In so doing, I have proposed three specific methods in using facet analysis: firstly, indexing system by facet analysis; secondly, the alternative transformation of the enumerative classification scheme into facet classification scheme; and finally, the facet model of subject directory of domestic search engine. After examining the three methods, my study concludes that a controlled vocabulary by facet analysis can be employed as a useful method in organizing Web resources.

This study aims to perform an evaluation of directory services provided by major Korean search portals: Naver, Daum, Yahoo-Korea, and Empas. A directory service of Open Directory is also compared. These directory services are evaluated in terms of the coverage, category creation criteria, site selection criteria, breadth and depth of hierarchy, clarity and currency of category names, order of category listing, and overall classification system. The results of this study can be implemented for the development and improvement of portal's directory services. Users can refer to the results of this study in choosing directory services from search portals.
