Watters, Carolyn; Amoudi, Ghada – Journal of the American Society for Information Science and Technology, 2003
Discussion of Web queries with geospatial dimensions focuses on an algorithm that assigns location coordinates dynamically to Web sites based on the URL. Describes a prototype search system that uses the algorithm to re-rank search engine results for queries with a geospatial dimension, thus providing an alternative ranking order for search engine…

Thelwall, Mike; Wilkinson, David – Journal of the American Society for Information Science and Technology, 2003
Explains how the Web can be modeled as a mathematical graph and analyzes the graph structures of three national university publicly indexable Web sites from Australia, New Zealand, and the United Kingdom. Topics include commercial search engines and academic Web link research; method-analysis environment and data sets; and power laws. (LRW)

Watters, Carolyn; Amoudi, Ghada – Proceedings of the ASIST Annual Meeting, 2002
Discusses search engines and describes a prototype system that provides dynamic ranking of search engine results for geospatial queries based on the URL of the host site. Evaluates this approach using user queries and random Web pages, making a contribution to Web retrieval by providing an alternative ranking order for search engine results.…

Tang, Rong; Thelwall, Mike – Proceedings of the ASIST Annual Meeting, 2002
Compares links between 76 Chinese university Web sites with ranks obtained from the NetBig lists, using a specialized Web crawler to collect data. Provides a background to the higher education system in mainland China, describes the NetBig ranking scheme, and explains Web site crawling problems encountered. (Author/LRW)

Wiggins, Richard – Searcher, 2003
Discussion of ranking systems used in various settings, including college football and academic admissions, focuses on the Google search engine. Explains the PageRank mathematical formula that scores Web pages by connecting the number of links; limitations, including authenticity and accuracy of ranked Web pages; relevancy; adjusting algorithms;…

Lempel, Ronny; Moran, Shlomo – Proceedings of the ASIST Annual Meeting, 2002
Discusses the use of link structure analysis in World Wide Web information retrieval and in retrieval and ranking algorithms of search engines. Presents two techniques which bias co-citation based link analyses towards favorable Web pages and away from undesired pages, and are then integrated into existing link-analyzing algorithms. (Author/LRW)

Bar-Ilan, Judit – Journal of Information Science, 2002
Discussion of bibliometric studies on the World Wide Web focuses on results of a search for links to the home page of the electronic journal "Cybermetrics". Presents results of a content analysis that showed search engines do not retrieve all the link pages that are indexed by them. (Author/LRW)

Hock, Ran – Online, 2002
Discusses various types of information that can be retrieved from the Web via search engines. Highlights include Web pages; time frames, including historical coverage and currentness; text pages in formats other than HTML; directory sites; news articles; discussion groups; images; and audio and video. (LRW)

Tillotson, Joy – Canadian Journal of Information and Library Science, 2003
Describes a survey that was conducted involving participants in the library instruction program at two Canadian universities in order to describe the characteristics of students receiving instruction in Web searching. Examines criteria for evaluating Web sites, search strategies, use of search engines, and frequency of use. Questionnaire is…
