    Abstract
    Explores some characteristics of the information superhigway and the WWW metaphors in the light of the current developments in information technology. These characteristics constitute a form of conceptual slippage, which helps us detect and predict the tacit impact that the currently available information delivery systems are having on human cognition. The particular language associated with these systems evolve as a direct result of human cognitive adaptations to the demands, resources and constraints of highly technological environments. discusses the role of metaphor as a vehicle for self-expression, as mediated by criteria of relevance

    Abstract
    Many libraries manage Web sites intended to provide their users with online resources suitable for answering reference questions. Most of these sites can be analyzed in terms of their depth, and their organizing and searching features. Composing a typology based on these factors sheds light on the critical design decisions that influence whether users of these sites succees or fail to find information easily, rapidly and accurately. The same analysis highlights some larger design issues, both for Web sites and for information management at large

    Abstract
    The WWW represents the final step in the evolution of the Internet and is a tool with many practical applications for library training. 2 such WWW applications are discussed in light of projects undertaken in the Helen Topping Architecture and Fine Arts Library at Southern California University. The WWW may be used as a resource in the library as a source of content which must be taught and should be presented to users along with the same information literacy skills which must accompany any resource. The WWW may be used as a publishing tool where the content is created according to the particular instructional need or situation. This usage involves the technology of the WWW rather than its content

    Abstract
    In the light of InfoSeek's extremely lucrative contract with Disney, analyses how it has made such a success of developing an Internet business through advertising revenues, and the imporatnce of powerful search engines. Reports 2 other deals by Internet search companies: NBC's purchase of a minority stake in the portal Snap!, owned by the Computer Network, Inc. and Yahoo's acquisition of Internet Mall and Viaweb which enable it to launch Yahoo Store hosting commerce sites on behalf of other companies allowing them to sell over the Internet. Outlines the possible consequences for users of these developments and of the possibility of Internet startups selling up and quitting the scene

    Abstract
    Twitter is utilized by many, including professional businesses and organizations; however, there are very few studies on how other entities interact with these organizations in the Twittersphere. This article presents a study that investigates tweets related to 5 major library and information science (LIS) professional organizations in the United States. This study applies a systematic tweets analysis framework, including descriptive analytics, network analytics, and co-word analysis of hashtags. The findings shed light on user engagement with LIS professional organizations and the trending discussion topics on Twitter, which is valuable for enabling more successful social media use and greater influence.

    Abstract
    Recent Web-searching and -mining tools are combining text and link analysis to improve ranking and crawling algorithms. The central assumption behind such approaches is that there is a correiation between the graph structure of the Web and the text and meaning of pages. Here I formalize and empirically evaluate two general conjectures drawing connections from link information to lexical and semantic Web content. The link-content conjecture states that a page is similar to the pages that link to it, and the link-cluster conjecture that pages about the same topic are clustered together. These conjectures are offen simply assumed to hold, and Web search tools are built an such assumptions. The present quantitative confirmation sheds light an the connection between the success of the latest Web-mining techniques and the small world topology of the Web, with encouraging implications for the design of better crawling algorithms.

    Abstract
    In this article, we explore the dynamics of prosocial and self-interested behavior among musicians on MySpace Music. MySpace Music is an important platform for social interactions and at the same time provides musicians with the opportunity for significant profit. We argue that these forces can be in tension with each other, encouraging musicians to make strategic choices about using MySpace to promote their own or others' rewards. We look for evidence of self-interested and prosocial friending strategies in the social network created by Top Friends links. We find strong evidence that individual preferences for prosocial and self-interested behavior influence friending strategies. Furthermore, our data illustrate a robust relationship between increased prominence and increased attention to others' rewards. These results shed light on how musicians manage their interactions in complex online environments and extend research on social values by demonstrating consistent preferences for prosocial or self-interested behavior in a multifaceted online setting.

    Abstract
    Webometrics is an information science field concerned with measuring aspects of the World Wide Web (WWW) for a variety of information science research goals. It came into existence about five years after the Web was formed and has since grown to become a significant aspect of information science, at least in terms of published research. Although some webometrics research has focused on the structure or evolution of the Web itself or the performance of commercial search engines, most has used data from the Web to shed light on information provision or online communication in various contexts. Most prominently, techniques have been developed to track, map, and assess Web-based informal scholarly communication, for example, in terms of the hyperlinks between academic Web sites or the online impact of digital repositories. In addition, a range of nonacademic issues and groups of Web users have also been analyzed.

    Abstract
    General sentiment analysis for the social web has become increasingly useful for shedding light on the role of emotion in online communication and offline events in both academic research and data journalism. Nevertheless, existing general-purpose social web sentiment analysis algorithms may not be optimal for texts focussed around specific topics. This article introduces 2 new methods, mood setting and lexicon extension, to improve the accuracy of topic-specific lexical sentiment strength detection for the social web. Mood setting allows the topic mood to determine the default polarity for ostensibly neutral expressive text. Topic-specific lexicon extension involves adding topic-specific words to the default general sentiment lexicon. Experiments with 8 data sets show that both methods can improve sentiment analysis performance in corpora and are recommended when the topic focus is tightest.
