본 연구에서는 사회학 분야 웹 정보원을 대상으로 동시링크분석을 실시하여 특정 학문분야의 지적구조를 분석하고, 검색엔진별 지적 구조의 차이를 분석함으로써 웹 정보원의 특성을 살펴보았다. 세 개의 검색엔진을 대상으로 지적구조의 차이를 비교한 결과, 웹 정보원 지도에서 전체적인 지적구조는 비슷하게 나타났지만, 몇 개의 웹 정보원의 경우에는 소속군집이 다르게 나타난 경우도 있었다. 그리고 Altavista와 AlltheWeb은 지도상의 웹 정보원 분포에 있어서 거의 유사한 구조를 보여주었다.

This research analyzed changes of the intellectual structure of web information by examining time changes and search engines using the co-links analysis. According to the results, the co-links web information clusters on the two maps appeared to contain changes in the intellectual structure over the two time periods. The intellectual structure that appeared in the information map for AltaVista and MSN Search engines was relatively similar. However. there were also cases where the clusters of some web information was different. The results of the research revealed that the cocitation analysis could be applied simultaneously to diachronous analysis in the web information.

The purpose of this study is to propose the criteria for evaluating web information resources. This study also attempts to get a sense of the overall quality of web information resources and to identify the relationship among the criteria, Particularly those on the science and technology. Three evaluation categories are Proposed; information content functionality or workability, and design. Core features of information content includes authority, relevancy, currency; functionality includes navigation, user support technical requirements; layout and design includes visual appearance. Based on the proposed criteria, the 50 sample web resources selected from 5 different field were evaluated. The results showed that the web information resources on the Electrical and Electronic Engineering field was excellent. The Pearson's correlation coefficient between evaluation criteria showed that information content and functionality had a negative relationship, on the other hand functionality and design had a moderate correlation.

This experimental study examines informetric analysis of World Wide Web based upon cocitation analysis of Web pages and features of Web resources in the field of communication studies. Cocitation analysis is basically performed to examine the intellectual structure of the communication studies in reflecting link count on the Web. The selected Web resources in the field are mapped in two dimensions based upon the similarities of cocitation frequency, correlation matrix, mutidimensional scale and cluster analysis. Cocitation analysis methods using organizational homepage, personal homepage, or Web index, to Web produced clustering of Web resources that had topical similarities. So far, although informetric analysis of Web resources is in the preliminary stage, it shows that Web can be a new tool for indicating the intellectual structure of a specific research field. In addition, this study analyzes characteristics of printing resources and Web resources, and differences of research methods in applying cocitation analysis.

The purpose of this study is to identify the current trends and characteristics of Korean internet searchable Web-based biographical resources by analyzing and evaluating in practices. Four among Korean Web-based biographical resources which have the comprehensive scope are chosen and evaluated by the 9 criteria and their detailed features. This study will allow users and reference librarians to more easily choose pertinent biographical references from the many internet resources. It will be also helpful by allowing publishers to produce more effective biographical information in quality.

The purpose of this study is to identify important web pages in a particular area The basic premise is that citation analysis can show a similar relationship among different web pages. Web pages about‘weather’were found using a search engine Each web page was examined by hyperlink from other web pases and/or to other web pages. After this process, seven web pases are linked by many web pages. Seven web pages were analyzed by co-citation analysis. The result shows that selected web pages are linked by characteristics of information provided.

This study used content analysis to examine the research methods in Library and Information Science journals from 1997 to 2001. Analyses measured research subjects, research method, data collection methods, data analysis methods, hypotheses, theories and research funds. Brief consideration is given to possible future methodological trends : web-based research methods, qualitative research, cooperation between academic society and librarians and research fundraising.

It became important to develop a wrapper for web information sources due to prevalence of information services through web information sources. We present a wrapper prototype that is a middleware to integrate web information sources. We present the derivation strategy of XML Schema from HTML documents and the query processing method based on XQJ. The usage example of wrapper API will show the usefulness of our prototype system.

인터넷에 존재하는 웹 문서와 사이트들은 충분히 학술적 가치를 갖고 있기 때문에 중요한 정보원으로 간주된다. 도서관은 이 새로운 정보원을 대상으로 도서관 이용자를 위한 새로운 검색기법과 관리기법을 개발할 필요가 증대되었다. 왜냐하면 현재 웹 검색 엔진에서 제공하는 분류체계는 도서관학적 관점에서 개발되지도 않았으며 또한 웹 검색엔진간 분류체계의 설계원칙도 없기 때문이다. 본 논문에서는 이점에 착안하여 웹문서를 효율적으로 검색할 수 있는 실험적인 새로운 웹 문서분류체계를 설계하였다. 설계는 해당 분류항목과 연관된 웹 문서의 수와 접속비율에 근거하였으며, 설계의 수준은 1차적으로 류·강 항목까지 제한하였다.

The Web information sources can be regarded as the largest distributed database to the users. By virtually integrating the distributed information sources and regarding them as a single huge database, we can query the database to extract information. This capability is important to develop Web application programs. We have to infer a database schema from browsing-oriented Web documents in order to integrate databases. This paper presents a heuristic algorithm to infer the XML Schema fully automatically from semi-structured Web documents. The algorithm first extracts candidate pattern regions based on predefined structure-making tags, and determines a target pattern region using a few heuristic factors, and then derives XML Schema extraction rules from the target pattern region. The schema extraction rule is represented in XQuery, which makes development of various application systems possible using open standard XML tools. We also present the experimental results for several public web sources to show the effectiveness of the algorithm.
