- Abstract
- Most on-line news sources are electronic versions of "ink-on-paper" newspapers. These are versions that have been filtered, from the mass of news produced each day, by an editorial board with a given community profile in mind. As readers, we choose the filter rather than choose the stories. New technology, however, provides the potential for personalized versions to be filtered automatically from this mass of news on the basis of user profiles. People read the news for many reasons: to find out "what's going on," to be knowledgeable members of a community, and because the activity itself is pleasurable. Given this, we ask the question, "How much filtering is acceptable to readers?" In this study, an evaluation of user preference for personal editions versus community editions of on-line news was performed. A personalized edition of a local newspaper was created for each subject based on an elliptical model that combined the user profile and community profile as represented by the full edition of the local newspaper. The amount of emphasis given the user profile and the community profile was varied to test the subjects' reactions to different amounts of personalized filtering. The task was simply, "read the news," rather than any subject specific information retrieval task. The results indicate that users prefer the coarse-grained community filters to fine-grained personalized filters

- Abstract
- My goal in this short article is to bring you up to speed on Web indexing. I assume you are a person with good word skills and an inquisitive mind. Also, I assume you have good keyboard skills, access to the Internet, and have already created some HTML pages using, say, Netscape Composer. You may need help from your Internet Service Provider (ISP) to upload pages onto your Web site. This article is based on my experience teaching an online interactive course in Web indexing for my company, WWWalker Web Development, in 1998. We develop Web sites, support Linux and Windows NT, write technical articles, and specialize in Web indexing.

- Abstract
- Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

- Abstract
- Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.

- Rez. in: JASIST 55(2004) no.6, S.561-562 (J.P. Renaud): "While definitions of democracy are topics of debate, political activists and potentates, respectively, hope or fear that a relationship exists between expanded access to information and expanded public interest in shaping policy. The current U.S. presidential election cycle has brought dramatic attention to this, with primary candidates using the Internet both to reach out to disaffected potential voters and to quite effectively raise funds for their campaigns. In short, this "new media" is no longer a novelty in the political arena, but a force that commands respect. In Democracy and New Media, the editors have assembled contributions from the social sciences, humanities, information science, and communication studies that attempt to address the relationship between democracy and evolving technology, using empirical and theoretical analysis. In addition, policy makers and shapers are represented in this volume, sharing interpretations of the impact of Internet technology upon democratic processes and structures. In keeping with the deliberative stance of the work, Clinton advisor Ira Magaziner's essay appears next to that of The Heritage Foundation's David Winton. The book's strength is that it is balanced in a way that reflects intellectual conceptions of both the Internet and democracy, and thus avoids the tendency of some other collections of essays to become either stridently one-sided or, worse, a point/ counterpoint collection along the lines of the basic Taking Sides series. This volume is the second in the Media in Transition Series, standing between New Media, 1740-1915, edited by Lisa Gitelman and Geoffrey Pingree, and Rethinking Media Change: The Aesthetics of Transition, edited by Jenkins and Thorburn. Democracy and the Internet: Some Considerations might have been a more accurate title for the volume under consideration here, because this tome poses questions and attempts to frame discussion, rather than provide concrete answers or definitive arguments. Andrew Feenberg's work, Questioning Technology (1999) and the essay collection Society an the Line: Information Politics in the Digital Age (1999), edited by William H. Dutton, will definitely be worthwhile reading for scholars interested in these topics. Other books that pursue similar lines of dialogue and are worth examining are the essay collection Virtual Politics: Identity and Community in Cyberspace (1997), edited by David Holmes, and Decomcracy.com? (1999), edited by Elaine Cuilla Kamarck and Joseph S. Nye, Jr. Articles that will complement these essays are Antje Gimmler's work, "Deliberative Democracy, the Public Sphere and the Internet," that appeared in Philosophy and Social Criticism 2 (2001), and a study by Thomas Johnson and Barbara Kaye, "A Boost or Bust for Democracy: How the Web Influenced Political Attitudes and Behaviors in the 1996 and 2000 Presidential Elections," that appeared in Press/Politics 8 (2003). Democracy and New Media is arranged around three themes. The first section, How Democratic Is Cyberspace? contains 11 essays. This is the most far-reaching and theoretical section of the book. The second section, a four-essay piece called Global Developments, raises some interesting questions that serve as micro examples of issues pursued at a more theoretical level in previous and subsequent chapters. The comparative nature of the volume is seen here, with chapters addressing the impact of technology an a nation interspersed with chapters that ultimately describe countries or regions where technology is absent in all but the most rudimentary forms. These contrasts, and the insights of the writers, allow seemingly disparate topics to become an intriguing dialogue. The third chapter, News and Information in the Digital Age, examines the changes created by faster and more accessible media.
... Any work addressing specific technology will soon be dated, but with their broad-based theoretical stance, the writers present frameworks that will be useful for graduate classes in information science, ethics, and, political science, well into the future. Aside from the content, the medium here does convey a message. A rudimentary citation analysis shows that 15.8% of the materials referenced in Democracy and the New Media are freely available an the Internet, allowing even readers who cannot easily access a research library to an increased level of interaction with the text. This suggests that in one way at least, Web technology is enhancing democracy. The impetus toward speed is also evident, with no fewer than five typos appearing in this edition, indicating the downside of attempting to deliberate and publish in this digitally paced world."

- Abstract
- The theme of "Organizing the Internet" brings to mind the late 1950s folk-rock singer Jimmie Rodgers's song titled "The World I Used to Know." A great many developments have transpired in the world of information science since the seminal works of S. C. Bradford, Claude Shannon, Vannevar Bush, and numerous other pioneers. To those of us who have been in the information science field for several decades, the peek-a-boo devices such as Termatrex, Mortimer Taube's Uniterm cards, and discussion of pre- and postcoordinate indexing have given way to the world of browsers, HTML, XML, and numerous other ways of coding text and multimedia. The Internet and the World Wide Web have had a profound impact on how we go about storing and retrieving information. Document integrity has become transient, with little assurance that the location, existence, or even the content of a publication will be the same tomorrow as even a few minutes ago. We are often hard-pressed to determine if the failure to retrieve a publication is one associated with network infrastructure or the publisher. The dream of universal bibliographic control seems quite remote. By being able to bypass traditional publication channels, anyone can publish virtually at will. The situation becomes more chaotic when we consider the increasing redundancy of knowledge and the rampant proliferation of misinformation and disinformation, to say nothing of social concerns with pornography, copyright violations, and other flagrant obtrusions into personal rights. Nevertheless, it behooves the information worker and the information user to make some sense of order if good information is to remain the basis of learning and decision making, and if documents are to continue as an archive of human knowledge.

- Abstract
- Provides a framework for analysing the utility, usability and likeability of net and web services and illustrates its application to significant aspects of supporting scholarly communities. The utility of the net and web are measured in terms of the growth of usage and the different services involved are distinguished in terms of their specific utilities. A layered protocol model is used to model discourse through the net and is extended to encompass interaction in communities. An operational criterion for distinguishing different communities is defined in terms of the types of awareness that resource providers and user have of one another. Develops a temporal model of discourse that enables the spectrum of services ranging from real-time discourse to long-term publication to be analyzed in a unified framework. The dimensions of awareness and time are used to characterise and compare the full range of net services and model their unification through the next generation of web browsers

- Abstract
- The nature and implications of electrocopying are summarised. After a brief review of the principles of copyright, the issue of whether electrocopying infringes copyright is debated. Publishers are aware of the threat that electrocopying poses to their business. The various options available to publishers for responding to electrocopying are summarised. Patterns of scholarly communications and the relationships between authors, publishers and libraries are being challenged. Constructive dialogue is necessary if the issues are to be resolved
