Abstract

Creating an information architecture for a bilingual Web site presents particular challenges beyond those that exist for single and multilanguage sites. This article reports work in progress an the development of a contentbased bilingual Web site to facilitate the sharing of resources and information between Speech and Language Therapists. The development of the information architecture is based an a combination of two aspects: an abstract structural analysis of existing bilingual Web designs focusing an the presentation of bilingual material, and a bilingual card-sorting activity conducted with potential users. Issues for bilingual developments are discussed, and some observations are made regarding the use of card-sorting activities.

Abstract

Many people fail to properly evaluate Internet information. This is often due to a lack of understanding of the issues surrounding evaluation and authority, and, more specifically, a lack of understanding of the structure and modi operandi of the Internet and the Domain Name System. The fact that evaluation is not being properly performed on Internet information means both that questionable information is being used recklessly, without adequately assessing its authority, and good information is being disregarded, because trust in the information is lacking. Both scenarios may be resolved by ascribing proper amounts of cognitive authority to Internet information. Traditional measures of authority present in a print environment are lacking on the Internet, and, even when occasionally present, are of questionable veracity. A formal model and evaluative criteria are herein suggested and explained to provide a means for accurately ascribing cognitive authority in a networked environment; the model is unique in its representation of overt and covert affiliations as a mechanism for ascribing proper authority to Internet information

Rez. in: JASIST 57(2006) no.12, S.1709-1710 (Y. Awazu): "This hook presents a collection of research studies on the creation, use, and deployment of digital information. According to the editors, the goal of the book is "to present results of scientific research on (I) how digital information has to be designed, (2) how artifacts or systems containing digital content should maximize usability, and (3) how context can influence the nature and efficiency of digital communication" (p. 2). Contributors to this volume have a wide assortment of backgrounds in information science, classical studies, cognitive science, information systems, and organizational sciences. The editors did an excellent job in designing the book. Each chapter is unique in its theory and method. The editors successfully put these unique chapters into the life-cycle view of information: creation, use, and deployment. . . . I would highly recommend this book as a supplementary text for graduate classes in information science, especially those dealing with the design of information systems. It was a pleasure to read this book, and I believe that readers will certainly gain from the wealth of knowledge and insights contained in the volume."

Abstract

This book provides practical strategies which enable the advanced web user to locate information effectively and to form a precise evaluation of the accuracy of that information. Although the book provides a brief but thorough review of the technologies which are currently available for these purposes, most of the book concerns practical `future-proof' techniques which are independent of changes in the tools available. For example, the book covers: how to retrieve salient information quickly; how to remove or compensate for bias; and tuition of novice Internet users.

Content

Key Features - Importantly, the book enables readers to develop strategies which will continue to be useful despite the rapidly-evolving state of the Internet and Internet technologies - it is not about technological `tricks'. - Enables readers to be aware of and compensate for bias and errors which are ubiquitous an the Internet. - Provides contemporary information an the deficiencies in web skills of novice users as well as practical techniques for teaching such users. The Authors Dr Alison Stacey works at the Learning Resource Centre, Cambridge Regional College. Dr Adrian Stacey, formerly based at Cambridge University, is a software programmer. Readership The book is aimed at a wide range of librarians and other information professionals who need to retrieve information from the Internet efficiently, to evaluate their confidence in the information they retrieve and/or to train others to use the Internet. It is primarily aimed at intermediate to advanced users of the Internet. Contents Fundamentals of information retrieval from the Internet - why learn web searching technique; types of information requests; patterns for information retrieval; leveraging the technology: Search term choice: pinpointing information an the web - why choose queries carefully; making search terms work together; how to pick search terms; finding the 'unfindable': Blas an the Internet - importance of bias; sources of bias; usergenerated bias: selecting information with which you already agree; assessing and compensating for bias; case studies: Query reformulation and longer term strategies - how to interact with your search engine; foraging for information; long term information retrieval: using the Internet to find trends; automating searches: how to make your machine do your work: Assessing the quality of results- how to assess and ensure quality: The novice user and teaching internet skills - novice users and their problems with the web; case study: research in a college library; interpreting 'second hand' web information.

Abstract

On the other hand, lack of trust motivates Lynch's observations. The Web world lacks social conventions for indexing markup, which permits struggles between those who would index the Web and those whose financial interest is in attracting the attention of the Web community. How trustworthy is Web information and how will that affect community?

Abstract

This article reviews selected literature related to the credibility of information, including (1) the general markers of credibility, and how different source, message and receiver characteristics affect people's perceptions of information; (2) the impact of information medium on the assessment of credibility; and (3) the assessment of credibility in the context of information presented on the Internet. The objective of the literature review is to synthesize the current state of knowledge in this area, develop new ways to think about how people interact with information presented via the Internet, and suggest next steps for research and practical applications. The review examines empirical evidence, key reviews, and descriptive material related to credibility in general, and in terms of on-line media. A general discussion of credibility and persuasion and a description of recent work on the credibility and persuasiveness of computer-based applications is presented. Finally, the article synthesizes what we have learned from various fields, and proposes a model as a framework for much-needed future research in this area

Abstract

Finding information an the Web can be a much more complex search process than previously experienced an many pre-Web information retrieval systems given that finding content online does not have to happen via a search algorithm typed into a search field. Rather, the Web allows for a myriad of search strategies. Although there are numerous studies of Web search techniques, these studies often limit their focus to just one part of the search process and are not based an the behavior of the general user population, nor do they include information about the users. To remedy these shortcomings, this project looks at how peopie find information online in the context of their other media use, their general Internet use patterns, in addition to using information about their demographic background and social support networks. This article describes the methodology in detail, and suggests that a mix of survey instruments and in-person observations can yield the type of rich data set that is necessary to understand in depth the differences in people's information retrieval behavior online.

Abstract

The Internet is increasingly being used as a source of reference information. Internet users need to be able to distinguish accurate information from inaccurate information. Toward this end, information professionals have published checklists for evaluating information. However, such checklists can be effective only if the proposed indicators of accuracy really do indicate accuracy. This study implements a technique for testing such indicators of accuracy and uses it to test indicators of accuracy for answers to ready reference questions. Many of the commonly proposed indicators of accuracy (e.g., that the Web site does not contain advertising) were not found to be correlated with accuracy. However, the link structure of the Internet can be used to identify Web sites that are more likely to contain accurate reference information.

Abstract

While the Web has become a worldwide platform for communication, terrorists share their ideology and communicate with members on the Dark Web - the reverse side of the Web used by terrorists. Currently, the problems of information overload and difficulty to obtain a comprehensive picture of terrorist activities hinder effective and efficient analysis of terrorist information on the Web. To improve understanding of terrorist activities, we have developed a novel methodology for collecting and analyzing Dark Web information. The methodology incorporates information collection, analysis, and visualization techniques, and exploits various Web information sources. We applied it to collecting and analyzing information of 39 Jihad Web sites and developed visualization of their site contents, relationships, and activity levels. An expert evaluation showed that the methodology is very useful and promising, having a high potential to assist in investigation and understanding of terrorist activities by producing results that could potentially help guide both policymaking and intelligence research.

Abstract

In this study, we attempt to evaluate the performance of the World Wide Web as an information resource in the domain of international travel. The theoretical framework underpinning our approach recognizes the contribution of models of information seeking behavior and of information systems in explaining World Wide Web usage as an information resource. Specifically, a model integrating the construct of uncertainty in information seeking and the task-technology fit model is presented. To test the integrated model, 217 travelers participated in a questionnaire-based empirical study. Our results confirm that richer (or enhanced) models are required to evaluate the broad context of World Wide Web (the Web) usage as an information resource. Use of the Web for travel tasks, for uncertainty reduction, as an information resource, and for mediation all have a significant impact an users' perception of performance, explaining 46% of the variance. Additionally, our study contributes to the testing and validation of metrics for use of the Web as an information resource in a specific domain.

Abstract

This paper deals with the problem of modeling Web information resources using expert knowledge and personalized user information for improved Web searching capabilities. We propose a "Web information space" model, which is composed of Web-based information resources (HTML/XML [Hypertext Markup Language/Extensible Markup Language] documents an the Web), expert advice repositories (domain-expert-specified metadata for information resources), and personalized information about users (captured as user profiles that indicate users' preferences about experts as well as users' knowledge about topics). Expert advice, the heart of the Web information space model, is specified using topics and relationships among topics (called metalinks), along the lines of the recently proposed topic maps. Topics and metalinks constitute metadata that describe the contents of the underlying HTML/XML Web resources. The metadata specification process is semiautomated, and it exploits XML DTDs (Document Type Definition) to allow domain-expert guided mapping of DTD elements to topics and metalinks. The expert advice is stored in an object-relational database management system (DBMS). To demonstrate the practicality and usability of the proposed Web information space model, we created a prototype expert advice repository of more than one million topics/metalinks for DBLP (Database and Logic Programming) Bibliography data set. We also present a query interface that provides sophisticated querying fa cilities for DBLP Bibliography resources using the expert advice repository.

Abstract

The scale of web site design has grown so that what was once comparable to decorating a room is now comparable to designing buildings or even cities. Designing sites so that people can find their way around is an ever-growing challenge as sites contain more and more information. In the past, Information Architecture for the World Wide Web has helped developers and designers establish consistent and usable structures for their sites and their information. This edition of the classic primer on web site design and navigation is updated with recent examples, new scenarios, and new information on best practices. Readers will learn how to present large volumes of information to visitors who need to find what they're looking for quickly. With topics that range from aesthetics to mechanics, this valuable book explains how to create interfaces that users can understand easily.

Abstract

Purpose - This research seeks to answer, "How do everyday Second Life users go about finding needed information?" as the primary research question. Design/methodology/approach - A virtual ethnographic approach couched in grounded theory was utilized to conduct semi-structured interviews with everyday users of Second Life, accompanied by participant observation. Findings - Information seeking behaviors within the virtual world of Second Life were found to be rich, complex interaction with multiple facets. Five themes emerged to illuminate how users seek information. Research limitations/implications - This research took place over a six-week period, although most enthographies last at least one year. Conclusions were drawn solely from interviews because participant observation did not penetrate a given community with enough depth to adequately address the research question. Practical implications - Virtual worlds offer the promise of becoming an integrated part of the information seeking landscape for an increasing number of users. Understanding the factors influencing information seeking behavior that are outlined in this article will equip librarians and information professionals to best utilize virtual worlds and continue to create innovative, user-focused services there. Originality/value - This article extends current scholarship by offering a practical, five-factor approach to understand how people seek information in virtual worlds. The literature is robust in description about library services and the nature of information in virtual worlds. Yet, investigation into information seeking behavior in this environment is in its nascent stages.

Abstract

Users of the Information Superhighway need signposts to find their way to appropriate, accurate and current information. Given the sheer quantity of information, intellectual indexing is more relevant than ever, complementing and augmenting automatic keyword indexing. Signposts come in various forms including browser bookmarks, local, on-site and remote lists, indexes and directories, temporary search engine results, and metadata. The considerable body of theory on vocabulary control for online database searching can be adapted to index construction for the Internet. At the same time, there are unresolved issues concerning information quality, indexing decisions, and standards
