Abstract

This article seeks to address the following questions: Why do certain people, who are fully information literate with printed materials, become hesitant and even reluctant when it comes to finding something on the Internet? And why do we, information professionals, find it difficult to support them adequately? Mature users of digital information are often skeptical about the value of the Internet as a source for professional information. Over the years much has been achieved, but many prophecies of the experts on digitalization from the early hours still have not yet been fulfilled. Mature users do possess all skills needed to be digital-information literate, but they need to be assisted in specific areas where those skills are insufficient. They tend to blame themselves even if shortcomings in accessibility of digital sources and computer errors obstruct their search. Operating hardware requires a dexterity that can only be acquired by experience. Instruction should be hands-on; demonstration is far less effective. Special attention should be given to reading and interpreting navigation information on the screen and to the search strategies the Internet requires. Use of imagination and trial-and-error methods are to be recommended in this respect.

Abstract

Online library catalogues and other information resources accessible through network connections offer students and scholars a variety of useful data, but present special problems to remote users. Issues facing the user of Internet-accessible systems include: knowing how to reach a system; finding out what a system contains; mastering commands and menu structures; using appropriate kinds of search terms; and choosing among systems to meet information needs effectively. These issues should be addressed by bibliographic instruction librarians and others who develop instructional units for access to systems on the Internet

Abstract

The unprecedented growth of the Internet has given rise to the Dark Web, the problematic facet of the Web associated with cybercrime, hate, and extremism. Despite the need for tools to collect and analyze Dark Web forums, the covert nature of this part of the Internet makes traditional Web crawling techniques insufficient for capturing such content. In this study, we propose a novel crawling system designed to collect Dark Web forum content. The system uses a human-assisted accessibility approach to gain access to Dark Web forums. Several URL ordering features and techniques enable efficient extraction of forum postings. The system also includes an incremental crawler coupled with a recall-improvement mechanism intended to facilitate enhanced retrieval and updating of collected content. Experiments conducted to evaluate the effectiveness of the human-assisted accessibility approach and the recall-improvement-based, incremental-update procedure yielded favorable results. The human-assisted approach significantly improved access to Dark Web forums while the incremental crawler with recall improvement also outperformed standard periodic- and incremental-update approaches. Using the system, we were able to collect over 100 Dark Web forums from three regions. A case study encompassing link and content analysis of collected forums was used to illustrate the value and importance of gathering and analyzing content from such online communities.

Abstract

This paper aims to explore the changes in the role of classification and the opportunities presented for classification in the twenty-first century, especially in respect to the development of information technology. The issues arose as part of the EC funded MIRACLE project that represents the foundation for a virtual music library to serve visually impaired people. The MIRACLE partners chose the UDC as the common classification for the converging music catalogues. This paper investigates the nature of adaptation required by each participating library and the way in which the classification is used as a searching tool. Further developments in the use of IT-assisted classification are proposed

Abstract

As a constantly changing resource, the Internet poses a challenge for bibliographic instruction librarians. Until recently, there has been little effort to survey Internet users about their search behaviours or source of Internet instruction. Focuses on survey data collected at Albany University, SUNY, early in 1995. It provides information about how users learned to use the Internet (mostly by themselves), the penetration of the Internet instruction programme (only 13% of those surveyed had attended), and public awareness of both instruction and the availability of Internet terminals in the university library

Abstract

Webtran tools for authoring and translating domain specific texts can make the multilingual text production in a company more efficient and less expensive. Tile tools have been in production use since spring 2000 for checking and translating product article texts of a specific domain, namely an in-company language in sales catalogues of a mail-order company. Webtran tools have been developed by VTT Information Technology. Use experiences have shown that an automatic translation process is faster than phrase-lexicon assisted manual translation, if an in-company language model is created to control and support the language used within the company

Rez. in: JASIST 55(2004) no.5, S.467-468 (W. Koehler): "Virtual Inequality is an important contribution to the digital divide debate. That debate takes two basic forms. One centers an the divide between the "information rich" developed countries and the "information poor" developing countries. The second is concerned with the rift between information "haves" and "have-nots" within countries. This book addresses the latter domain and is concerned with the digital divide in the United States. This book is the product of a cross-disciplinary collaboration. Mossberger and Tolbert are both members of the Kent State University political science department while Stansbury is an the Library and Information Science faculty. The book is extremely well documented. Perhaps the chapter an the democracy divide and e-government is the best done, reflecting the political science bent of two of the authors. E-government is very well covered. Unfortunately, e-commerce and e-education go virtually unmentioned. If e-government is important to defining the digital divide, then certainly e-commerce and e-education are as well. Mossberger, Tolbert, and Stansbury argue that the digital divide should be described as four different divides: the access divide, the skills divide, the economic opportunity divide, and the democratic divide. Each of these divides is developed in its own chapter. Each chapter draws well an the existing literature. The book is valuable if for no other reason than that it provides an excellent critique of the current state of the understanding of the digital divide in the United States. It is particularly good in its contrast of the approaches taken by the Clinton and George W. Bush administrations. Perhaps this is a function of the multidisciplinary strength of the book's authorship, for indeed it shows here. The access divide is defined along "connectivity" lines: who has access to digital technologies. The authors tonfirm the conventional wisdom that age and education are important predictors of in-home access, but they also argue that rate and ethnicity are also factors (pp. 32-33): Asian Americans have greatest access followed by whites, Latinos, and African Americans in that order. Most access the Internet from home or work, followed by friends' computers, libraries, and other access points. The skills divide is defined as technical competence and information literacy (p. 38). Variation was found along technical competence for age, education, affluence, rate, and ethnicity, but not gender (p. 47). The authors conclude that for the most part the skills divide mirrors the access divide (p. 55). While they found no gender difference, they did find a gender preference for skills acquisition: males prefer a more impersonal delivery ("online help and tutorials") while females prefer more personal instruction (p. 56).
The economic opportunity divide is predicated an the hypothesis that there has, indeed, been a major shift in opportunities driven by changes in the information environment. The authors document this paradigm shift well with arguments from the political and economic right and left. This chapter might be described as an "attitudinal" chapter. The authors are concerned here with the perceptions of their respondents of their information skills and skill levels with their economic outlook and opportunities. Technological skills and economic opportunities are correlated, one finds, in the minds of all across all ages, genders, races, ethnicities, and income levels. African Americans in particular are ". . attuned to the use of technology for economic opportunity" (p. 80). The fourth divide is the democratic divide. The Internet may increase political participation, the authors posit, but only among groups predisposed to participate and perhaps among those with the skills necessary to take advantage of the electronic environment (p. 86). Certainly the Web has played an important role in disseminating and distributing political messages and in some cases in political fund raising. But by the analysis here, we must conclude that the message does not reach everyone equally. Thus, the Internet may widen the political participation gap rather than narrow it. The book has one major, perhaps fatal, flaw: its methodology and statistical application. The book draws upon a survey performed for the authors in June and July 2001 by the Kent State University's Computer Assisted Telephone Interviewing (CATI) lab (pp. 7-9). CATI employed a survey protocol provided to the reader as Appendix 2. An examination of the questionnaire reveals that all questions yield either nominal or ordinal responses, including the income variable (pp. 9-10). Nevertheless, Mossberger, Tolbert, and Stansbury performed a series of multiple regression analyses (reported in a series of tables in Appendix 1) utilizing these data. Regression analysis requires interval/ratio data in order to be valid although nominal and ordinal data can be incorporated by building dichotomous dummy variables. Perhaps Mossberger, Tolbert, and Stansbury utilized dummy variables; but 1 do not find that discussed. Moreover, 1 would question a multiple regression made up completely of dichotomous dummy variables. I come away from Virtual Inequality with mixed feelings. It is useful to think of the digital divide as more than one phenomenon. The four divides that Mossberger, Tolbert, and Stansbury offeraccess, skills, economic opportunity, and democratic-are useful as a point of departure and debate. No doubt, other divides will be identified and documented. This book will lead the way. Second, without question, Mossberger, Tolbert, and Stansbury provide us with an extremely well-documented, -written, and -argued work. Third, the authors are to be commended for the multidisciplinarity of their work. Would that we could see more like it. My reservations about their methodological approach, however, hang over this review like a shroud."

Abstract

This article compares search effectiveness when using query-based Internet search (via the Google search engine), directory-based search (via Yahoo), and phrase-based query reformulation-assisted search (via the Hyperindex browser) by means of a controlled, user-based experimental study. The focus was to evaluate aspects of the search process. Cognitive load was measured using a secondary digit-monitoring task to quantify the effort of the user in various search states; independent relevance judgements were employed to gauge the quality of the documents accessed during the search process and time was monitored as a function of search state. Results indicated directory-based search does not offer increased relevance over the query-based search (with or without query formulation assistance), and also takes longer. Query reformulation does significantly improve the relevance of the documents through which the user must trawl, particularly when the formulation of query terms is more difficult. However, the improvement in document relevance comes at the cost of increased search time, although this difference is quite small when the search is self-terminated. In addition, the advantage of the query reformulation seems to occur as a consequence of providing more discriminating terms rather than by increasing the length of queries

Footnote

The volume is organized into 13 sections, each of which contains between two and eight conference papers. As with most conferences, the papers do not cover the issues in each section with equal weight or depth but the editors have grouped papers into reasonable patterns. Section 1 covers "understanding online behavior" with eight papers on problems such as e-learning attitudes, the neuropsychology of HCI, Japanese blogger motivation, and the dividing line between computer addiction and high engagement. Sections 2 (personality and computer attitudes), 3 (cyber interactions), and 4 (new interaction methods) each contain only two papers on topics such as helmet-mounted displays, online energy audits, and the use of ICT in family life. Sections 6, 7, and 8 focus on gender issues with papers on career development, the computer literacy of Malaysian women, mentoring, gaming, and faculty job satisfaction. Sections 9 and 10 move to a broader examination of cyber society and its diversity concerns with papers on cultural identity, virtual architecture, economic growth's impact on culture, and Iranian development impediments. Section 11's two articles on advertising might well have been merged with those of section 13's ebusiness. Section 12 addressed education with papers on topics such as computer-assisted homework, assessment, and Web-based learning. It would have been useful to introduce each section with a brief definition of the theme, summaries of the major contributions of the authors, and analyses of the gaps that might be addressed in future conferences. Despite the aforementioned concerns, this volume does provide a uniquely rich array of technological analyses embedded in social context. An examination of recent works in related areas finds nothing that is this complex culturally or that has such diversity of disciplines. Cultural Production in a Digital Age (Klinenberg, 2005), Perspectives and Policies on ICT in Society (Berleur & Avgerou, 2005), and Social, Ethical, and Policy Implications of Information Technology (Brennan & Johnson, 2004) address various aspects of the society/Internet intersection but this volume is unique in its coverage of psychology, gender, and culture issues in cyberspace. The lip service often given to global concerns and the value of interdisciplinary analysis of intransigent social problems seldom develop into a genuine willingness to listen to unfamiliar research paradigms. Academic silos and cultural islands need conferences like this one-willing to take on the risk of examining the large questions in an intellectually open space. Editorial and methodological concerns notwithstanding, this volume merits review and, where appropriate, careful consideration across disciplines."
