    Abstract
    Die Webometrie ist ein Teilbereich der Informationswissenschaft der zur Zeit auf die Analyse von Linkstrukturen konzentriert ist. Er ist stark von der Zitationsanalyse geprägt, wie der empirische Schwerpunkt auf der Wissenschaftsanalyse zeigt. In diesem Beitrag diskutieren wir die Nutzung linkbasierter Maße in einem breiten informetrischen Kontext und bewerten verschiedene Verfahren, auch im Hinblick auf ihr generelles Potentialfür die Sozialwissenschaften. Dabei wird auch ein allgemeiner Rahmenfür Linkanalysen mit den erforderlichen Arbeitsschritten vorgestellt. Abschließend werden vielversprechende zukünftige Anwendungsfelder der Webometrie benannt, unter besonderer Berücksichtigung der Analyse von Blogs.

    Abstract
    This is the era of social networking, collective intelligence, participation, collaborative creation, and borderless distribution. Every day we are bombarded with more publicity about collaborative environments, news feeds, blogs, wikis, podcasting, webcasting, folksonomies, social bookmarking, social citations, collaborative filtering, recommender systems, media sharing, massive multiplayer online games, virtual worlds, and mash-ups. This sort of anarchic environment appeals to the digital natives, but which of these so-called 'Web 2.0' technologies are going to have a real business impact? This paper addresses the impact that issues such as quality control, security, privacy and bandwidth may have on the implementation of social networking in hide-bound, large organizations.

    Abstract
    Purpose - The purpose of this paper is to analyze the disciplinary orientation of scientific publications that were mentioned on different social media platforms, focussing on their differences and similarities with citation counts. Design/methodology/approach - Social media metrics and readership counts, associated with 500,216 publications and their citation data from the Web of Science database, were collected from Altmetric.com and Mendeley. Results are presented through descriptive statistical analyses together with science maps generated with VOSviewer. Findings - The results confirm Mendeley as the most prevalent social media source with similar characteristics to citations in their distribution across fields and their density in average values per publication. The humanities, natural sciences, and engineering disciplines have a much lower presence of social media metrics. Twitter has a stronger focus on general medicine and social sciences. Other sources (blog, Facebook, Google+, and news media mentions) are more prominent in regards to multidisciplinary journals. Originality/value - This paper reinforces the relevance of Mendeley as a social media source for analytical purposes from a disciplinary perspective, being particularly relevant for the social sciences (together with Twitter). Key implications for the use of social media metrics on the evaluation of research performance (e.g. the concentration of some social media metrics, such as blogs, news items, etc., around multidisciplinary journals) are identified.

    Abstract
    This article presents the consequences to librarians and teachers for the flattening of expertise, or the Google Effect. As blogs continue to fill the Web with the bizarre daily rituals and opinions of people who we would never bother speaking to at a party, let alone invite into our homes, there has never been a greater need to stress the importance of intelligence, education, credentials and credibility. The problem is not only accuracy, but also the mediocrity initiated through the Google Effect. The concern is not with the banality of information - there has always been a plurality of sources in the analogue environment. The concern is the lack of literacy skills and strategies to sort the trash from the relevant. This paper addresses not only the social choices about computer use and information literacy, but the intellectual choices we make in our professional lives as teachers and librarians. In such a time, the Google Effect raises stark questions about the value of reading, research, writing and scholarship.

    Abstract
    Authorship attribution supported by statistical or computational methods has a long history starting from the 19th century and is marked by the seminal study of Mosteller and Wallace (1964) on the authorship of the disputed Federalist Papers. During the last decade, this scientific field has been developed substantially, taking advantage of research advances in areas such as machine learning, information retrieval, and natural language processing. The plethora of available electronic texts (e.g., e-mail messages, online forum messages, blogs, source code, etc.) indicates a wide variety of applications of this technology, provided it is able to handle short and noisy text from multiple candidate authors. In this article, a survey of recent advances of the automated approaches to attributing authorship is presented, examining their characteristics for both text representation and text classification. The focus of this survey is on computational requirements and settings rather than on linguistic or literary issues. We also discuss evaluation methodologies and criteria for authorship attribution studies and list open questions that will attract future work in this area.

    Abstract
    A huge number of informal messages are posted every day in social network sites, blogs, and discussion forums. Emotions seem to be frequently important in these texts for expressing friendship, showing social support or as part of online arguments. Algorithms to identify sentiment and sentiment strength are needed to help understand the role of emotion in this informal communication and also to identify inappropriate or anomalous affective utterances, potentially associated with threatening behavior to the self or others. Nevertheless, existing sentiment detection algorithms tend to be commercially oriented, designed to identify opinions about products rather than user behaviors. This article partly fills this gap with a new algorithm, SentiStrength, to extract sentiment strength from informal English text, using new methods to exploit the de facto grammars and spelling styles of cyberspace. Applied to MySpace comments and with a lookup table of term sentiment strengths optimized by machine learning, SentiStrength is able to predict positive emotion with 60.6% accuracy and negative emotion with 72.8% accuracy, both based upon strength scales of 1-5. The former, but not the latter, is better than baseline and a wide range of general machine learning approaches.

    Abstract
    This study explores knowledge organization behavior on the Web with respect to identifying the semantic relationships of health-related concepts. In particular, this study aims to investigate the potentials of imparting richer collective intelligence to existing knowledge representation systems in health. The study focuses on detecting semantic relationships between semantic groups of major concepts mined from health consumers' descriptions of health issues and associated user-generated metadata (i.e., tags). A total of 50,263 blogs and associated 341,720 tags were collected from Tumblr, a blogging social networking site. Text mining and semantic network analysis methods were used to explore the usage patterns at semantic type levels of the identified medical concepts in tags, in blogs, and between tags and blogs. More various associations among semantic types were identified both in tags and in blogs. These associations were more diverse and complicated than the relationships in the Unified Medical Language System Semantic Network. Among the groups of concepts in tags and blogs, groups showed relatively stronger and more diverse relationships with other groups of concepts. In addition, many direct and close relations were found between tags and blogs.

    Abstract
    Glaubt man den zumeist etwas volkstümlichen Beschreibungen, so sind Blogs »private Online-Tagebücher«, »Piratensender im Internet«, gleichermaßen Konkurrenz und Kontrollinstanz zu etablierten Medien, eine authentische Informationsquelle, Trendbarometer, nicht immer glaubwürdig, »haben Magazin-Charakter« und sind auf jeden Fall »das nächste große Ding«. Auch wenn das zuletzt genannte Attribut wohl am ehesten konsensfähig ist, wäre ein Blog, das all dies in sich vereinigt, wohl ein Kuriosum. Vielmehr bildet der Begriff »Weblog«, kurz »Blog«, eine Klammer für unterschiedlichste Online-Publikationen, während die Eigenschaften, die allen Blogs gemein sind, unspektakulär daherkommen: Aktuelle Beiträge, verfasst in einem unaufwändigen Content-ManagementSystem, dargestellt in umgekehrt chronologischer Reihenfolge und in aller Regel mit Kommentarfunktion versehen [@I]. Der technische Blickwinkel ist zwar leicht zu konkretisieren, für große Emotionen aber nicht besonders ergiebig. Es gibt zahlreiche Anbieter, die einem nach wenigen Klicks ein schlüsselfertiges Blog anbieten, wie z.B. der inzwischen zu Google gehörende Dienst Blogger.com, das deutsche Unternehmen blogg.de oder der sympathische österreichische Anbieter twoday.net. Technisch versiertere Nutzer installieren sich ihr gesamtes Blogsystem gleich auf einem eigenen Server und nutzen die zahlreichen zusätzlichen Möglichkeiten, die Systeme wie MovableType, WordPress, Nucleus und Co. zur Verfügung stellen.

    Abstract
    This study examines cancer patients' and companions' uses and gratifications of blogs and the relationship between different types of blogging activities and gratification outcomes. In an online survey of 113 respondents, cancer patients were found to be more likely than their companions to host their own blogs. Four areas emerged as gratifications of blog use: prevention and care, problem-solving, emotion management, and information-sharing. Cancer patients and companions both found blogging activity to be most helpful for emotion management and information-sharing. Further, cancer patients were more gratified than their companions in the areas of emotion management and problem-solving. Regression analyses indicate that perceived credibility of blogs, posting comments on others' blogs, and hosting one's own blog significantly increased the explanatory power of the regression models for each gratification outcome.
