    Abstract
    Purpose - Social websites have become a major medium for social interaction. From Facebook to MySpace to emergent sites like Twitter, social websites are increasing exponentially in user numbers and unique visits every day. How do these websites encourage sociability? What features or design practices enable users to socialize with other users? The purpose of this paper is to explore sociability on the social web and details how different social websites encourage their users to interact. Design/methodology/approach - Four social websites (Facebook, MySpace, LinkedIn and Twitter) were examined from a user study perspective. After thoroughly participating on the websites, a series of observations were recorded from each experience. These experiences were then compared to understand the different approaches of each website. Findings - Social websites use a number of different approaches to encourage sociability amongst their users. Facebook promotes privacy and representing "real world" networks in web environment, while MySpace promotes publicity and representing both real world and virtual networks in a web environment. Niche websites like LinkedIn and Twitter focus on more specific aspects of community and technology, respectively. Originality/value - A comparison of different models of sociability does not yet exist. This study focuses specifically on what makes social websites "social."

    Abstract
    Social networks evolve over time with the addition and removal of nodes and links to survive and thrive in their environments. Previous studies have shown that the link-formation process in such networks is influenced by a set of facilitators. However, there have been few empirical evaluations to determine the important facilitators. In a research partnership with law enforcement agencies, we used dynamic social-network analysis methods to examine several plausible facilitators of co-offending relationships in a large-scale narcotics network consisting of individuals and vehicles. Multivariate Cox regression and a two-proportion z-test on cyclic and focal closures of the network showed that mutual acquaintance and vehicle affiliations were significant facilitators for the network under study. We also found that homophily with respect to age, race, and gender were not good predictors of future link formation in these networks. Moreover, we examined the social causes and policy implications for the significance and insignificance of various facilitators including common jails on future co-offending. These findings provide important insights into the link-formation processes and the resilience of social networks. In addition, they can be used to aid in the prediction of future links. The methods described can also help in understanding the driving forces behind the formation and evolution of social networks facilitated by mobile and Web technologies.

    Abstract
    This study examines the criteria questioners use to select the best answers in a social Q&A site (Yahoo! Answers) within the theoretical framework of relevance research. A social Q&A site is a novel environment where people voluntarily ask and answer questions. In Yahoo! Answers, the questioner selects the answer that best satisfies his or her question and leaves comments on it. Under the assumption that the comments reflect the reasons why questioners select particular answers as the best, this study analyzed 2,140 comments collected from Yahoo! Answers during December 2007. The content analysis identified 23 individual relevance criteria in six classes: Content, Cognitive, Utility, Information Sources, Extrinsic, and Socioemotional. A major finding is that the selection criteria used in a social Q&A site have considerable overlap with many relevance criteria uncovered in previous relevance studies, but that the scope of socio-emotional criteria has been expanded to include the social aspect of this environment. Another significant finding is that the relative importance of individual criteria varies according to topic categories. Socioemotional criteria are popular in discussion-oriented categories, content-oriented criteria in topic-oriented categories, and utility criteria in self-help categories. This study generalizes previous relevance studies to a new environment by going beyond an academic setting.

    Abstract
    With increasing user presence in the Web and Web 2.0, Web social mining becomes an important and challenging task that finds a wide range of new applications relevant to e-commerce and social software. In this entry, we describe three Web social mining topics, namely, social network discovery, social network analysis, and social network applications. The essential concepts, models, and techniques of these Web social mining topics will be surveyed so as to establish the basic foundation for developing novel applications and for conducting research.

    Content
    "Millionen von Internet-Nutzern drängen in soziale Netze wie StudiVZ und Facebook. Diese Online-Plattformen für die Vernetzung von persönlichen Web-Auftritten entwickeln sich zu einer neuen Art von Massenmedium, wie der Digitale-Medien-Experte Hendrik Speck sagt. Völlig offen sei aber bislang die Frage nach der gesellschaftlichen Verantwortung der "Social Networks". "Die haben mehr Informationen, als die Stasi je hatte", sagt der Informatik-Professor der Fachhochschule Kaiserslautern im Gespräch mit der Nachrichtenagentur AP. Bei den drei Plattformen Facebook, MySpace und Xing hat Speck insgesamt 120 persönliche Attribute gezählt, die auf den persönlichen Seiten der Mitglieder angegeben werden können - angefangen bei Alter und Wohnort über Lieblingsfilme und -musik bis hin zu politischer Neigung und sexueller Ausrichtung. "Wir sehen da einen völlig irrationalen Zugang zu den eigenen Daten", kritisiert der Social-Networks-Forscher. Was aber treibt die Internet-Nutzer zu dieser Art von "digitalem Exhibitionismus"? Speck und seine Studenten haben die Kommunikation in den Netzen mit Hilfe von Software-Agenten und "Crawlern" zu erfassen versucht - das sind Programme, die auf die Seiten dieser Communities vordringen und die Inhalte auswerten. "Wir stellen fest, dass da unheimlich viel offen liegt", sagt Speck. Suche nach Anerkennung und Aufmerksamkeit Als wichtige Antriebskraft hat der Wissenschaftler das Motiv ausgemacht, über den stetig wachsenden Kreis von registrierten "Freunden" Anerkennung und Aufmerksamkeit zu erringen. Bei MySpace oder im SchülerVZ kann sich jeder auf eine Weise präsentieren, wie es in den klassischen Medien kaum möglich ist. Und weil die persönlichen Profile mit wenigen Mausklicks schnell erstellt sind, ist die Eintrittsschwelle sehr viel geringer als bei den Netz-Communities der ersten Stunde, etwa der schon 1985 gegründeten virtuellen Gemeinschaft "The WELL".
    Bislang sind es meist Jugendliche und junge Erwachsene bis etwa 35, die die Mehrheit der Community-Mitglieder ausmachen. Es gebe aber Bestrebungen, die Altersgruppe nach oben zu erweitern, sagt Speck. Die soziale Interaktion in den Social Networks kreist nach seinen Erkenntnissen immer wieder um die gleichen Dinge: 1) Unterhaltung - von Musik bis zu Stars und Sternchen 2) die gesellschaftlich geteilte Schadenfreude nach dem Motto "Pleiten, Pech und Pannen" 3) Flirten und sexuelle Beziehungen. Dabei kommen Männer direkter auf den Punkt als Frauen, die dies hinter anderen Interessen verstecken. Auf der anderen Seite stehen die Betreiber der Netze. Diese erzielen mit der Bereitstellung der Plattform zwar bislang meist noch keine Gewinne, haben aber wegen der gigantischen Zuwachsraten das Interesse von Internet- und Medienunternehmen geweckt, die wie Microsoft oder die Verlagsgruppe Holtzbrinck in Social Networks investieren. Der einzelne Nutzer ist 20 bis 22 Dollar wert Da die Technik der Webseiten nicht besonders aufwendig sei, liege der eigentliche Reichtum in den Nutzern und ihren Daten, erklärt Speck. Bei den großen Plattformen in den USA lasse sich aus den getätigten Investitionen für die Social Networks der Wert eines einzelnen Nutzers auf einen Betrag von 20 bis 22 Dollar (14 bis 15 Euro) schätzen. Der Gegenwert, den die Nutzer liefern sollen, wird vor allem in der Werbung gesehen. Neben der klassischen Bannerwerbung auf den eigenen Seiten versuchen die Betreiber der sozialen Netzwerke nach Darstellung Specks, in andere Dienste wie SMS-Werbung oder E-Mail vorzudringen. Um die Werbe-Zielgruppen immer feiner zu erfassen, werde auch untersucht, wer mit welchem Profil mit wem kommuniziere. "Je tiefer die Vernetzung, desto dichter werden die Informationen", erklärt Speck.
    Der Wissenschaftler kritisiert, dass die Daten so behandelt würden, als gehörten sie nicht dem Nutzer, sondern den sozialen Netzwerken. Selbst wenn es die Möglichkeit gebe, einen Account zu löschen, blieben die Daten vielfach weiter bestehen. Und über die beliebten Mini-Anwendungen zur Integration in die eigene Profilseite erhielten auch die Entwickler dieser Applikationen einen Zugang zu den persönlichen Daten. "Da weiß man dann gar nicht, wer dahinter steckt." Weder "open" noch "social" Google hat Anfang November vergangenen Jahres unter der Bezeichung OpenSocial eine Initiative gestartet, um solche Anwendungen und Schnittstellen nach einheitlichen Standards programmieren zu können. Das Projekt sei aber weder "open" noch "social", weil nicht vorgesehen sei, den Nutzern eine transparente Kontrolle über ihre eigenen Daten zu geben, bemängelt der FH-Professor. Das Projekt bemühe sich um die "Datenportabilität" zwischen den kommerziellen Projektpartnern und unterstütze die Interaktionen zwischen einzelnen Communities, versage jedoch komplett bei der Interessenswahrnehmung der Nutzer in Hinblick auf informationelle Selbstbestimmung und einem verbesserten Schutz der Privatssphäre. Um die zahlreichen offenen Fragen nach der Verantwortung für die Millionen von persönlichen Daten zu klären, schlägt Speck einen Verhaltenskodex für soziale Netzwerke vor. Für die gemeinsame Entwicklung von ethischen Grundsätzen will er neben Datenschützern auch die Betreiber der Communities gewinnen und hofft, schon in wenigen Monaten eine entsprechende Initiative vorstellen zu können. http://www.hendrikspeck.com"

    Abstract
    When we were all facing the turn of the century and the somewhat larger turn of the millennium, we left behind epochs of colonialism, imperialism, capitalism, nazism and racialism. Not that the ideologies mentioned does no longer exist, but their impact as grand narratives has gone and they now exist as fragmented discursive parts of their former, illusive hegemony. Parts that have been thrown into the pits of post modern complexity. The 21st century holds no answers, no new meaning, at most it provides human communication a certain self reflectivity due to the increasing egocentrism and individuality of people (i.e. still mostly western people). Another symptom of the loss of grand narratives is a feeling of loss of meaning in everyday life, as well as the state of democracies around the world. Democracy shivers in its void between anarchy and repressive dictatorship. The description 'information age' provides the times we are in with a useful sticker. It tents both back in time e.g. the late 20, century digitalisation and forward in time by givingr origin to the contemporary discourse of social semantics i.e. Dream society, Knowledge society, Post modern society, Risk society, Hypercomplex society etc. The phrase 'information age' implied the introduction of a paradigm shift, and now it is still here showing that paradigms do not shift, they slide. This paper outlines a manifest for librarians and librarianship of the information age. The information age puts the spotlight on the librarian, both regarding classical tasks such as classification and cataloguing as well as new tasks such as systems analysis and design or database searching.
    Complexity establishes a paradox between the tasks of preserving old knowledge (memory function) and facilitate cognitive dissonance in order to challenge established knowledge claims and create new knowledge (catalyser function). Through complexity all social systems organisations, discourse communities, ideologies) face an environment (or surrounding) that is characterised through its instability and contingency. What is real, or presumable real from one point of view can appear completely different from another point of view. Different discourses of meaning and significance float, blend and separates themselves form each other the arena of communication. The library has to both keep record of what has happened, as well as take part in the ongoing battles for new discursive hegemonies. The unity of the paradox of memory and catalysing is described as managing complexity and requires a conscious and constant oscillation between order and chaos, stability and change. The role of the librarian is defined through an analysis of contemporary social semantics as well as the technical, ethical, cultural and epistemological challenges facing us as librarians and information specialists.

    Abstract
    Technological developments have changed the concepts of publication, reproduction and distribution. However, legislation, and in particular the Legal Deposit Law has not adjusted to these changes - it is very restrictive in the sense of protecting the rights of authors of electronic publications. National libraries and national archival institutions, being aware of their important role in preserving the written and spoken cultural heritage, try to find different legal ways to live up to these responsibilities. This paper presents some legal aspects of archiving Web pages, examines the harvesting of Web pages, provision of public access to pages, and their long-term preservation.

    Abstract
    Purpose - The "photosharing" site Flickr is one of the most commonly cited examples used to define Web2.0. This paper aims to explore where Flickr's real novelty lies, examining its functionality and its place in the world of amateur photography. Several optimistic views of the impact of Flickr such as its facilitation of citizen journalism, "vernacular creativity" and in learning as an "affinity space" are evaluated. Design/methodology/approach - The paper draws on a wide range of sources including published interviews with its developers, user opinions expressed in forums, telephone interviews and content analysis of user profiles and activity. Findings - Flickr's development path passes from an innovative social game to a relatively familiar model of a web site, itself developed through intense user participation but later stabilising with the reassertion of a commercial relationship to the membership. The broader context of the impact of Flickr is examined by looking at the institutions of amateur photography and particularly the code of pictorialism promoted by the clubs and industry during the twentieth century. The nature of Flickr as a benign space is premised on the way the democratic potential of photography is controlled by such institutions. The limits of optimistic claims about Flickr are identified in the way that the system is designed to satisfy commercial purposes, continuing digital divides in access and the low interactivity and criticality on Flickr. Originality/value - Flickr is an interesting source of change, but can only be understood in the perspective of long-term development of the hobby and wider social processes. By setting Flickr in such a broad context, its significance and that of Web2.0 more generally can be fully assessed.

    Abstract
    The importance of trust in building and maintaining consumer relationships in the online environment is widely accepted in the Information Systems literature. A key challenge for researchers is to identify antecedent variables that engender consumer trust in Internet shopping. This paper adopts a multidisciplinary approach and develops an integrative model of consumer trust in Internet shopping through synthesizing the three diverse trust literatures. The social psychological perspective guides us to include perceived trustworthiness of Internet merchants as the key determinant of consumer trust in Internet shopping. The sociological viewpoint suggests the inclusion of legal framework and third-party recognition in the research model. The views of personality theorists postulate a direct effect of propensity to trust on consumer trust in Internet shopping. The results of this study provide strong support for the research model and research hypotheses, and the high explanatory power illustrates the complementarity of the three streams of research on trust. This paper contributes to the conceptual and empirical understanding of consumer trust in Internet shopping. Implications of this study are noteworthy for both researchers and practitioners.

    Abstract
    There is an "information burst" going on in our world. Therefore we think more about the role of information in modern society and in our personal life. The political waves of the peaceful revolutionary process virtually start to erase the borders of the countries drawn on the maps. A little more than ten years ago we had not even a concept for "Belarusian-German relations", because both countries "the new united Germany and the Republic of Belarus did not exist on the maps of the world. Today the communication between our countries covers all aspects of public life "culture" science and education. We have laid a foundation for our economic and cultural cooperation. We already have had some experience in the joint solution of internal and international problems. And "what is most striking" the warm human contacts of the people consolidate and accelerate the process of mutual understanding between our countries and broaden our view. Today no country in the world can yield their citizens more freedom of choice than the "state" of the Internet. The people, freely migrating in a boundless information space, know how to use the invaluable treasures of human thought and creatively increase the achievements of mankind by intellectual work. These people become the pride of every country in our time. In educating, shaping and supporting such persons we see a new social role of the libraries. It is clearly visible that libraries turn into modern information centers. The introduction of new information know-how and the access to electronic information by means of an electronic library satisfy the increasing need of effective and comprehensive information. All steps of the work with documents (publication "search" delivery) are automated. The fast electronic delivery of documents is promoted by the growth of global information networks, by the increase of transfer rates of dates" by the capability of online search in the electronic catalogues and databases connected with the automated systems of the ordering of copies, by the technical equipment and software of scanning and recognition of the text.

    Abstract
    Die unter dem Schlagwort "Web 2.0" zusammengefassten Technologien des Social Web beweisen eindrucksvoll, wie erfolgreich kollaboratives Arbeiten in intuitiv zu bedienenden Systemen sein kann. Das Social Web ist von keiner zentralen Autorität gesteuert; Nutzer können sich in vielen Social Web Sites in jeweils neuen Gruppen zusammenfinden und gemeinsam Inhalte erstellen und austauschen. Solche kollaborativen Prozesse haben längst Einzug gehalten in Unternehmen, um Projekte zu koordinieren, zu dokumentieren und umzusetzen. Dort existieren jedoch strenge Vorgaben, wer welche Informationen sehen und verändern darf. Das behindert den spontanen Umgang mit der neuen Technik und verlangt den Einsatz der aus anderen Informationssystemen bekannten Methoden, Informationen vor unberechtigtem Zugriff zu schützen. In diesem Artikel wird der Einsatz der durch Social Tagging gewonnenen Informationen zum Festlegen von Richtlinien zur Zugriffskontrolle beleuchtet. Viele funktionale und deskriptive Tags geben Aufschluss auf den gewünschten Personenkreis, der auf die zugrunde liegende Ressource zugreifen können soll. Die vorgeschlagene Architektur basiert auf Semantic Web Regeln, mit deren Hilfe Tags in Sicherheitsrichtlinien übersetzt werden.

    Abstract
    Purpose - Argues that the internet has an important contribution to make to the improvement of the democratic process, but that this contribution can only be effective with advocacy and support from information professionals and educators; the cultivation of eLiteracy by such information professionals and educators is vital in delivering the democratic potential of the internet. Design/methodology/approach - An opinion piece based on current and recent trends in thinking about digital citizenship, the internet and democracy. Findings - Hopeful initial visions of the impact of internet technologies on democracy have been shown to be in some ways too optimistic. Many of the most notable social impacts of the internet on our collective well-being have been harmful. The cultivation of eLiteracy as a democratic attribute of citizenship should enable us to make the most of the social beneficent potential of the networks. Research limitations/implications - Purely an expression of belief about what may prove to be the likely social and political benefits of promoting eLiteracy as an aspect of enhanced citizenship. Offers potential for exploration via more in-depth research. Practical implications - Opens up an optimistic social and political purpose to the cultivation of eLiteracy in a broad mass of citizens. Originality/value - Affirms an optimistic view of the democratic potential of the internet, but makes it clear that this potential will not emerge of its own accord. Citizens must engage intelligently with the social and political issues raised by the internet, in particular with the issue of how the new media enable the electorate to conduct dialogue with government. Information professionals have a particular civic duty to be aware of the democratic significance of their promotion of information literacy and, more specifically, of eLiteracy.

    Abstract
    In 2007, the social networking Web site MySpace apparently overthrew Google as the most visited Web site for U.S. Web users. If this heralds a new era of widespread online social networking, then it is important to investigate user behaviour and attributes. Although there has been some research into social networking already, basic demographic data is essential to set previous results in a wider context and to give insights to researchers, marketers and developers. In this article, the demographics of MySpace members are explored through data extracted from two samples of 15,043 and 7,627 member profiles. The median declared age of users was surprisingly high at 21, with a small majority of females. The analysis confirmed some previously reported findings and conjectures about social networking, for example, that female members tend to be more interested in friendship and males more interested in dating. In addition, there was some evidence of three different friending dynamics, oriented towards close friends, acquaintances, or strangers. Perhaps unsurprisingly, female and younger members had more friends than others, and females were more likely to maintain private profiles, but both males and females seemed to prefer female friends, with this tendency more marked in females for their closest friend. The typical MySpace user is apparently female, 21, single, with a public profile, interested in online friendship and logging on weekly to engage with a mixed list of mainly female friends who are predominantly acquaintances.

    Abstract
    Link analysis in various forms is now an established technique in many different subjects, reflecting the perceived importance of links and of the Web. A critical but very difficult issue is how to interpret the results of social science link analyses. lt is argued that the dynamic nature of the Web, its lack of quality control, and the online proliferation of copying and imitation mean that methodologies operating within a highly positivist, quantitative framework are ineffective. Conversely, the sheer variety of the Web makes application of qualitative methodologies and pure reason very problematic to large-scale studies. Methodology triangulation is consequently advocated, in combination with a warning that the Web is incapable of giving definitive answers to large-scale link analysis research questions concerning social factors underlying link creation. Finally, it is claimed that although theoretical frameworks are appropriate for guiding research, a Theory of Link Analysis is not possible.

    Abstract
    This article examines the impact of the Internet and the age distribution of research scholars on academic citation age with a mathematical model proposed by Barnett, Fink, and Debus (1989) and a revised model that incorporates information about the online environment and scholar age distribution. The modified model fits the data well, accounting for 99.6% of the variance for science citations and 99.8% for social science citations. The Internet's impact on the aging process of academic citations has been very small, accounting for only 0.1% for the social sciences and 0.8% for the sciences. Rather than resulting in the use of more recent citations, the Internet appears to have lengthened the average life of academic citations by 6 to 8 months. The aging of scholars seems to have a greater impact, accounting for 2.8% of the variance for the sciences and 0.9% for the social sciences. However, because the diffusion of the Internet and the aging of the professoriate are correlated over this time period, differentiating their effects is somewhat problematic.

    Abstract
    The proposal is to use clusters, graphs and networks as models in order to analyse the Web structure. Clusters, graphs and networks provide knowledge representation and organization. Clusters were generated by co-site analysis. The sample is a set of academic Web sites from the countries belonging to the European Union. These clusters are here revisited from the point of view of graph theory and social network analysis. This is a quantitative and structural analysis. In fact, the Internet is a computer network that connects people and organizations. Thus we may consider it to be a social network. The set of Web academic sites represents an empirical social network, and is viewed as a virtual community. The network structural properties are here analysed applying together cluster analysis, graph theory and social network analysis. This is a work having taken place in the EICSTES project. EICSTES means European Indicators, Cyberspace, and the Science-Technology-Economy System. It is a research project supported by the Fifth Framework Program of R&D of the European Commission (IST-1999-20350)

    Abstract
    Given a snapshot of a social network, can we infer which new interactions among its members are likely to occur in the near future? We formalize this question as the link-prediction problem, and we develop approaches to link prediction based on measures for analyzing the "proximity" of nodes in a network. Experiments on large coauthorship networks suggest that information about future interactions can be extracted from network topology alone, and that fairly subtle measures for detecting node proximity can outperform more direct measures.

    Abstract
    The aim of this paper is to study the link relationships in the Nordic academic web space - comprised of 23 Finnish, 11 Danish and 28 Swedish academic web domains with the European one. Through social networks analysis we intend to detect sub-networks within the Nordic network, the position and role of the different university web domains and to understand the structural topology of this web space. Co-link analysis, with asymmetrical matrices and cosine measure, is used to identify thematic clusters. Results show that the Nordic network is a cohesive network, set up by three well-defined sub-networks and it rests on the Finnish and Swedish sub-networks. We conclude that the Danish network has less visibility than other Nordic countries. The Swedish one is the principal Nordic sub-network and the Finland network is a slightly isolated from Europe, with the exception of the University of Helsinki.
