Abstract

Review Global Explorer 1.0, a CD-ROM interactive atlas of the world. Global Explorer includes searchable references to more than 120.000 places and street maps of 100 cities throughout the world. The program also contains descriptions of 20.000 historical, cultural, geographical and social features and information on the geography, government, economy and population for each country of the world. The search process is described and the program evaluated. Although the user interface has some shortcomings and there are some errors in the database, Global Explorer is a unique and intersting way to explore the world and would be a beneficial additions to the map, public and school library

Abstract

Describes the INSPEC database, claimed to be the world's largest English language bibliographic database, as well as the most comprehensive available for physics, electronics and computing. Traces the development of 'Science Abstracts' from its 1st issue published in Jan 1898 which contained 110 abstracts: 1.423 were included during this initial year. Examines subsequent growth and development, emphasizing the commitment to quality, extension of the Physics coverage, the CD-ROM database and the total of 5,75 million records included at the end of 1997. Current growth is 300.000 records per year, from over 4.000 journals and serials, plus 2.000 conference proceedings and other materials

Abstract

Purpose Wikipedia has the lofty goal of compiling all human knowledge. The purpose of the present study is to map the structure of the Traditional Chinese Medicine (TCM) knowledge domain on Wikipedia, to identify patterns of knowledge representation on Wikipedia and to test the applicability of author bibliographic coupling analysis, an effective method for mapping knowledge domains represented in published scholarly documents, for Wikipedia data. Design/methodology/approach We adapted and followed the well-established procedures and techniques for author bibliographic coupling analysis (ABCA). Instead of bibliographic data from a citation database, we used all articles on TCM downloaded from the English version of Wikipedia as our dataset. An author bibliographic coupling network was calculated and then factor analyzed using SPSS. Factor analysis results were visualized. Factors were labeled upon manual examination of articles that authors who load primarily in each factor have significantly contributed references to. Clear factors were interpreted as topics. Findings Seven TCM topic areas are represented on Wikipedia, among which Acupuncture-related practices, Falun Gong and Herbal Medicine attracted the most significant contributors to TCM. Acupuncture and Qi Gong have the most connections to the TCM knowledge domain and also serve as bridges for other topics to connect to the domain. Herbal medicine is weakly linked to and non-herbal medicine is isolated from the rest of the TCM knowledge domain. It appears that specific topics are represented well on Wikipedia but their conceptual connections are not. ABCA is effective for mapping knowledge domains on Wikipedia but document-based bibliographic coupling analysis is not. Originality/value Given the prominent position of Wikipedia for both information users and for researchers on knowledge organization and information retrieval, it is important to study how well knowledge is represented and structured on Wikipedia. Such studies appear largely missing although studies from different perspectives both about Wikipedia and using Wikipedia as data are abundant. Author bibliographic coupling analysis is effective for mapping knowledge domains represented in published scholarly documents but has never been applied to mapping knowledge domains represented on Wikipedia.

Abstract

As academic libraries wrestle with how to provide more CD-ROMs and more online remote access to databases to keep pace with demands, they first need to evaluate the effectiveness of their current services. This study identifies students' preferences and effectiveness using CD-ROMs and assesses the whole CD-ROM environment at one university library. A questionnaire was used to ask students their preferences, confidence levels, skills, and training in searching CD-ROM databases, as well as their satisfaction with CD-ROM services. Analyses of the data revealed that users are satisfied and prefer CD-ROM databases over the print indices. Although students indicated they are confident searching, they admitted that they need to know basic search strategies and that they want more personal assistance, hands-on training, and remote online access to databases. Moreover, how can academic libraries meet increasing user demands for more database access and services when their resources are not increasing?

Abstract

More than 100 U.S. governmental agencies offer links through FedStats, a centralized Web site that facilitates access to statistical tables, reports, and agencies. This and similar large collections need appropriate interfaces to guide the general public to easily and successfully find information they seek. This paper summarizes the results of 3 empirical studies of alternate organization concepts of the FedStats Topics Web page. Each study had 15 participants. The evolution from 645 alphabetically organized links, to 549 categorically organized links, to 215 categorically organized links tied to portal pages produced a steady rise in successful task completion from 15.6 to 24.4 to 42.2%. User satisfaction also increased. We make recommendations based an these data and our observations of users.

Abstract

Wikipedia, like other encyclopedias, includes biographies of notable people. However, because it is jointly written by many contributors, it is subject to constant manipulation by contributors attempting to add biographies of non-notable people. Over time, Wikipedia has developed inclusion criteria for notable people (e.g., receiving a significant award) based on which newly contributed biographies are evaluated. In this paper we present and analyze a set of simple indicators that can be used to predict which article will eventually be accepted. These indicators do not refer to the content itself, but to meta-content features (such as the number of categories that the biography is associated with) and to author-based features (such as if it is a first-time author). By training a classifier on these features, we successfully reached a high predictive performance (area under the receiver operating characteristic [ROC] curve [AUC] of 0.97) even though we overlooked the actual biography text.

Abstract

Using the Arts & Humanities Citation Index (A&HCI) 2008, we apply mapping techniques previously developed for mapping journal structures in the Science and Social Sciences Citation Indices. Citation relations among the 110,718 records were aggregated at the level of 1,157 journals specific to the A&HCI, and the journal structures are questioned on whether a cognitive structure can be reconstructed and visualized. Both cosine-normalization (bottom up) and factor analysis (top down) suggest a division into approximately 12 subsets. The relations among these subsets are explored using various visualization techniques. However, we were not able to retrieve this structure using the Institute for Scientific Information Subject Categories, including the 25 categories that are specific to the A&HCI. We discuss options for validation such as against the categories of the Humanities Indicators of the American Academy of Arts and Sciences, the panel structure of the European Reference Index for the Humanities, and compare our results with the curriculum organization of the Humanities Section of the College of Letters and Sciences of the University of California at Los Angeles as an example of institutional organization.
