- Abstract
- Examines the use of networked information sources in scholarly communication. Networked information sources are defined broadly to cover: documents and images stored on electronic network hosts; data files; newsgroups; listservs; online information services and electronic periodicals. Reports results of a survey to determine how heavily, if at all, networked information sources are cited in scholarly printed periodicals published in 1993 and 1994. 27 printed periodicals, representing a wide range of subjects and the most influential periodicals in their fields, were identified through the Science Citation Index and Social Science Citation Index Journal Citation Reports. 97 articles were selected for further review and references, footnotes and bibliographies were checked for references to networked information sources. Only 2 articles were found to contain such references. Concludes that, although networked information sources facilitate scholars' work to a great extent during the research process, scholars have yet to incorporate such sources in the bibliographies of their published articles

- Abstract
- Citation analysis has long been used by librarians as an important tool of collection development and the advent of Internet technology and especially the WWW adds a new facet to the role played by citation analysis. One of the reasons why librarians create WWW homepages is to provide users with further sources of interest or reference and to do this libraries include links from their own homepages to other information sources. Reports current research on the analysis of WWW pages as an introduction to an examination of the homepages of 25 art libraries to determine what sites are most often included. The types of linked sites are analyzed based on 3 criteria: location, focus and evidence that the link was evaluated before the connection was establisheds

- Abstract
- Reports the preliminary results of an investigation into the effectiveness of colinked descriptors, a new concept and technique suitable for incorporating into the design of interfaces for information retrieval. The idea is borrowed from the analogous idea in bibliometrics-cocited references. Preliminary results suggest that the technique is extremely effective. As a retrieval technique, colinked descriptors can easily be incorporated into information retrieval interfaces, front-end systems, or standalone, pre-search systems

- Abstract
- Reports results of a cocitation analysis study from the international retrieval research field from 1987 to 1997. Data was taken from Social SciSearch, via Dialog, and the top 40 authors were submitted to author cocitation analysis to yield the intellectual structure of information retrieval. The resulting multidimensional scaling map revealed: identifiable author groups for information retrieval; location of these groups with respect to each other; extend of centrality and peripherality of authors within groups, proximities of authors within groups and across group boundaries; and the meaning of the axes of the map. Factor analysis was used to reveal the extent of the authors' research areas and statistical routines included: ALSCAL; clustering analysis and factor analysis

- 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
- Draws attention to the vast potential of online information databases and to the many new possibilities which advanced search techniques offer those who want to explore databases. Looks at informetrics, an emerging subfield in information science, which is based on the combination of advanced information retrieval and quantitative studies of information flow. Describes 3 studies carried out at the Centre for Information studies at the Royal School of Library and Information Science in Copenhagen, Denmark, to illustrate the scope and nature of informetric analysis

- Abstract
- 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
- 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

- Abstract
- Zipf's law was used to qualify all the key words of documents in a data set. This qualification was used to build a graphical representation of the resulting indicator in each document. The graphical resolution leads to a document dispatch in a 3 dimensional space. This graphical representation was used as an information retrieval tool without using any keyword. The presentation of a case study is available on the WWW. The graph is drawn in VRML allowing a dynamic picture which is linked to a database management system (FreeWAIS)

- 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
- 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
