- Abstract
- Investigates the retrieval capabilities of 6 Internet search engines on a simple query. Existing work on search engine evaluation considers only the first 10 or 20 results returned by the search engine. In this work, all documents that the search engine pointed at were retrieved and thoroughly examined. Thus the precision of the whole retrieval process could be calculated, the overlap between the results of the engines studied, and an estimate on the recall of the searches given. The precision of the engines is high, recall is very low and the overlap is minimal

- Abstract
- Continued development of the Internet requires the development of efficient, easy-to-use search engines. Ideally, such development should call upon knowledge and skills from a variety of disciplines, including computer science, information science, psychology, and ergonomics. The current study is intended to determine whether search engines shows a pattern of interdisciplinarity. 2 disciplines were selected as the focus for the study: computer science, and library/information science. A citation analysis was conducted to measure levels of interdisciplinary research and publishing in Internet search engine design and development. The results show a higher level of interdisciplinarity among library and information scientists than among computer scientists or among any of those categorized as 'other'. This is reflected both in the types of journals in which the authors publish, and in the references they cite to support their work. However, almost no authors published articles or cited references in fields such as cognitive science, ergonomics, or psychology. The results of this study are analyzed in terms of the writings of Patrick Wilson, Bruno Latour, Pierre Bordieu, Fritz Ringer, and Thomas Pinelli, focusing on cognitive authority within a profession, interaction between disciplines, and information-gathering habits of professionals. Suggestions for further research are given

- Abstract
- Reports investigations into the feasibility and reliability of calculating impact factors for web sites, called Web Impact Factors (Web-IF). analyzes a selection of 7 small and medium scale national and 4 large web domains as well as 6 institutional web sites over a series of snapshots taken of the web during a month. Describes the data isolation and calculation methods and discusses the tests. The results thus far demonstrate that Web-IFs are calculable with high confidence for national and sector domains whilst institutional Web-IFs should be approached with caution

- Abstract
- Although the Internet is not without its critics, many popular and academic writers are particular effusive in the praise of the WWW's interactive features. A content analysis of the formal features of 496 Web sites, drawn randomly from a sample of the top 5.000 most visited sites determined by 100hot.com, was performed to explore whether the capabilities of the WWW are being exploited by Web page designers to the extent that the literature suggests they are. Specifically, the study examines the differences between the formal features of commercial versus non-commercial sites as well as the relationship between Web page complexity and the amount of traffic a site receives. Findings indicate that, although most pages in this stage of the Web's development remain technological simple and noninteractive, there are significant relationships between site traffic and home-page structure for Web sites in the commercial (.com) as well as educational (.edu) domains. As the Web continues to expand and the amount of information redundancy increases, it is argued that a site's information packaging will become increasingly important in gaining users' attention and interest

- Abstract
- This article introduces a new concept and technique for information retrieval called 'colinked descriptors'. Borrowed from an analogous idea in bibliometrics - cocited references - colinked descriptors provide a theory and method for identifying search terms that, by hypothesis, will be superior to those entered initially by a searcher. The theory suggests a means of moving automatically from 2 or more initial search terms, to other terms that should be superior in retrieval performance to the 2 original terms. A research project designed to test this colinked descriptor hypothesis is reported. The results suggest that the approach is effective, although methodological problems in testing the idea are reported. Algorithms to generate colinked descriptors can be incorporated easily into system interfaces, front-end or pre-search systems, or help software, in any database that employs a thesaurus. The potential use of colinked descriptors is a strong argument for building richer and more complex thesauri that reflect as many legitimate links among descriptors as possible

- Abstract
- Online searchers today no longer limit themselves to locating references to articles. More and more, they are called upon to locate specific answers to questions such as: Who is my chief competitor for this technology? Who is publishing the most on this subject? What is the geographic distribution of this product? These questions demand answers, not necessarily from record content, but from statistical analysis of the terms in a set of records. Most online services now provide a tool for statistical analysis such as GET on Orbit, ZOOM on ESA/IRS and RANK/RANK FILES on Dialog. With these commands, users can analyze term frequency to extrapolate very precise answers to a wide range of questions. This paper discusses the many uses of term frequency analysis and how it can be applied to areas of competitive intelligence, market analysis, bibliometric analysis and improvements of search results. The applications are illustrated by examples from Dialog

- Asserts that duality is an important topic in informetrics, especially in connection with the classical informetric laws. Yet this concept is less studied in information retrieval. It deals with the unification or symmetry between queries and documents, search formulation versus indexing, and relevant versus retrieved documents. Elaborates these ideas and highlights the connection with the hypergeometric distribution

- Abstract
- Scientific information has stopped growing exponentially as in the last 300 years. Nevertheless, the number of scientific papers published yearly remains dramatic. Well orderd databases and sophisticated search systems allow scientists to find the needle in the haystack. A growing number of factual databases as well as more reviews compress and refine information. Not searching but controlling and working up information appear to become the most important problem in the future

- Abstract
- Reports results of an automated search of the term 'information technology' and 20 related terms in the ERIC database, 1982-1991, which revealed data related to: scientific production relating to information technology; core journals; types of documents; types of authors and their output; sponsoring institutions; publishing output by country; desciptors; and related terms. The following bibliometric laws are applied: Bradford's law; Lotka's law; and Spearman's and Pearson's laws. Provides an insight into the role of bibliometrics as a scientific discipline for the study of the development of new technologies and their impact on information activity

- Abstract
- Reports results of a study, conducted at Kansas State University Library, to investigate the possibility of using DIALOG's RANK command to generate lists of prominent authors for use in cocitation studies. The emerging and rapidly expanding field of biodiversity was chosen and an online search of SCISEARCH (DIALOG File 34) was conducted to generate a list of potential authors to be used in the study. The RANK command was used to generate a ranked list of those authors cited in the retrieved documents. Results indicate that RANK does not effectively retrieve a quality set of prominent authors for use in cocitation studies. Highly cited authors of general texts of biodiversity cause the derived author map to present a misaligned picture of specialization within the field. Concludes that, by limiting citations to periodical articles only, a clearer and more accurate picture of the field should emerge
