    Abstract
    The web has been, in the last decades, the place where information retrieval achieved its maximum importance, given its ubiquity and the sheer volume of information. However, its exponential growth made the retrieval task increasingly hard, relying in its effectiveness on idiosyncratic and somewhat biased ranking algorithms. To deal with this problem, a "new" web, called the Semantic Web (SW), was proposed, bringing along concepts like "Web of Data" and "Linked Data," although the definitions and connections among these concepts are often unclear. Based on a qualitative approach built over a literature review, a definition of SW is presented, discussing the related concepts sometimes used as synonyms. It concludes that the SW is a comprehensive and ambitious construct that includes the great purpose of making the web a global database. It also follows the specifications developed and/or associated with its operationalization and the necessary procedures for the connection of data in an open format on the web. The goals of this comprehensive SW are the union of two outcomes still tenuously connected: the virtually unlimited possibility of connections between data-the web domain-with the potentiality of the automated inference of "intelligent" systems-the semantic component.

    Abstract
    S R Ranganathan's ideas have influenced library classification since the inception of his Colon Classification in 1933. His address at Elsinore, "Library Classification Through a Century", was his grand vision of the century of progress in classification from 1876 to 1975, and looked to the future of faceted classification as the means to provide a cohesive system to organize the world's information. Fifty years later, the internet and its achievements, social ecology, and consequences present a far more complicated picture, with the library as he knew it as a very small part and the problems that he confronted now greatly exacerbated. The systematic nature of Ranganathan's canons, principles, postulates, and devices suggest that modern semantic algorithms could guide automatic subject tagging. The vision presented here is one of internet-wide faceted classification and retrieval, implemented as open, distributed facets providing unified faceted searching across all web sites.

    Abstract
    Das Semantic Web und seine Auswirkungen auf Bibliotheken rücken immer mehr in den Fokus informationswissenschaftlicher Forschung. Dieser Artikel erläutert grundlegende funktionale wie technische Konzepte des Semantic Web, um darauf aufbauend in das Thema Library Linked Data einzuführen. Dafür werden einige kürzlich entstandene Projekte und Initiativen vorgestellt. Neben den Visionen und Zielen der jeweiligen Initiatoren, wie bessere Sichtbarkeit von bibliographischen Daten und Entwicklung neuer Applikationen, werden auch offene technische und rechtliche Fragestellungen bzw. Probleme kurzangerissen. In einem letzten Punkt werden mögliche praktische Linked Data-Anwendungsfalle für den österreichischen Kontext vorgestellt.

    Abstract
    Die Transformation vom Web der Dokumente hin zum Web von Daten stellt die informationswissenschaftliche Gemeinschaft vor neue Herausforderungen. Der Beitrag zeigt, wie diese Aufgabe durch die gegenseitige Vernetzung untereinander und mit Experten außerhalb der eigenen Gemeinschaft bewältig werden kann. Mit Hilfe der Theorie " Communities of Practice" werden die essentiellen Elemente einer solchen Vernetzung bestimmt und vom Autor besuchte Veranstaltungen daraufhin evaluiert. Es wird deutlich, dass diese Art der Vernetzung besonders für junge Informationsspezialistinnen vorteilhaft ist.

    Abstract
    Die Deutsche Nationalbibliothek (DNB) hat damit begonnen, ihre Wissensbasis bestehend aus bibliografischen Daten einerseits, vor allem aber aus den Normdaten als Linked Data zu veröffentlichen. Ziel der DNB ist es, mit der Publikation der Daten als Tripel eine direkte Nutzung der gesamten nationalbibliografischen Daten und der Normdaten durch die Semantic-WebCommunity zu ermöglichen und damit ganz neue Nutzungsgruppen einzubinden. Gleichzeitig soll aber auch das Tor für einen neuen Weg der kooperativen Datennutzung aufgestoßen werden. Langfristiges Ziel ist es, Bibliotheken und andere kulturelle Einrichtungen als ein verlässliches Rückgrat des Webs der Daten zu etablieren.

    Abstract
    We discuss the needs of a knowledge organization scheme for supporting Web-based software applications. We show how it differs from traditional knowledge organization schemes due to the virtual, dynamic, ad-hoc, userspecific and application-specific nature of Web-based knowledge. The sheer size of Web resources also adds to the complexity of organizing knowledge on the Web. As such, a standard, global scheme such as a single ontology for classifying and organizing all Web-based content is unrealistic. There is nevertheless a strong and immediate need for effective knowledge organization schemes to improve the efficiency and effectiveness of Web-based applications. In this context, we propose a novel knowledge organization scheme wherein concepts in the ontology of a domain are semantically interlinked with specific pieces of Web-based content using a rich hyper-linking structure known as Superlinks with well-defined semantic roles. We illustrate how such a knowledge organization scheme improves the efficiency and effectiveness of a Web-based e-commerce retail store.

Beide Systeme setzen auf einen konsequenten Einsatz von Persistenten Identifikatoren (URN und DOI), was die Verknüpfung der durch dalra registrierten Daten mit den Volltextdokumenten aus SSOAR sowie anderen Informationen aus den GESIS-Beständen ermöglicht. Zusätzlich wird durch den Einsatz von semantischen Technologien wie SKOS und RDF eine Verbindung zum Semantic Web hergestellt.

    Abstract
    Purpose - The purpose of this paper is to investigate concepts that are used in depicting future visions of society, as afforded by technology, to map the extent of their use, examine the level of their dominance in different research areas and geographic boundaries, identify potential overlaps, analyse their longitudinal growth, and examine whether any of the identified concepts has assumed an overarching position. Design/methodology/approach - In total, 14 concepts, each of which is used to depict visions of future information infrastructures, were identified. More than 20,000 scholarly documents related to 11 of these concepts (those with 20 or more documents) are analysed by various qualitative/quantitative methods. Findings - The concepts most referred to are semantic web and ubiquitous computing (all years), and internet of things (Year 2013). Publications on some newer concepts (e.g. digital living, real world internet) are minimal. There are variations in the extent of use and preferred concepts based on geographic and disciplinary boundaries. The overlap in the use of these terms is minimal and none of these terms has assumed an overarching umbrella position. Research limitations/implications - This study is limited to scholarly publications; it would be relevant to also study the pattern of usage in governmental communications and policy documents. Social implications - By mapping multiplicity of concepts and the dispersion of discussions, the authors highlight the need for, and facilitate, a broader discussion of related social and societal implications. Originality/value - This paper is the first to present a collective of these related concepts and map the pattern of their occurrence and growth.

    Abstract
    Spam and wildly varying documents make searching in Twitter challenging. Most Twitter search systems generally treat a Tweet as a plain text when modeling relevance. However, a series of conventions allows users to Tweet in structural ways using a combination of different blocks of texts. These blocks include plain texts, hashtags, links, mentions, etc. Each block encodes a variety of communicative intent and the sequence of these blocks captures changing discourse. Previous work shows that exploiting the structural information can improve the structured documents (e.g., web pages) retrieval. In this study we utilize the structure of Tweets, induced by these blocks, for Twitter retrieval and Twitter opinion retrieval. For Twitter retrieval, a set of features, derived from the blocks of text and their combinations, is used into a learning-to-rank scenario. We show that structuring Tweets can achieve state-of-the-art performance. Our approach does not rely on social media features, but when we do add this additional information, performance improves significantly. For Twitter opinion retrieval, we explore the question of whether structural information derived from the body of Tweets and opinionatedness ratings of Tweets can improve performance. Experimental results show that retrieval using a novel unsupervised opinionatedness feature based on structuring Tweets achieves comparable performance with a supervised method using manually tagged Tweets. Topic-related specific structured Tweet sets are shown to help with query-dependent opinion retrieval.

    Abstract
    This paper introduces a project to develop a reliable, cost-effective method for classifying Internet texts into register categories, and apply that approach to the analysis of a large corpus of web documents. To date, the project has proceeded in 2 key phases. First, we developed a bottom-up method for web register classification, asking end users of the web to utilize a decision-tree survey to code relevant situational characteristics of web documents, resulting in a bottom-up identification of register and subregister categories. We present details regarding the development and testing of this method through a series of 10 pilot studies. Then, in the second phase of our project we applied this procedure to a corpus of 53,000 web documents. An analysis of the results demonstrates the effectiveness of these methods for web register classification and provides a preliminary description of the types and distribution of registers on the web.

    Abstract
    Der Beitrag behandelt informationswissenschaftliche Perspektiven des Social Web. Hierzu wird zunächst anhand technologischer und sozialer Entwicklungstendenzen des Internets eine begriffliche Annäherung vorgenommen und die sich daraus ergebenden Phänomene mittels einer exemplarischen Darstellung wichtiger Dienste und Anwendungen veranschaulicht. Darauf aufsetzend wird das Social Web aus gesellschaftlicher Perspektive als eine globale Architektur der Partizipation eingeordnet, die in langfristiger Sicht das Potential für strukturelle Umbrüche in vielfältigen Bereichen und Handlungsfeldern in sich birgt. Dabei lassen sich aus informationswissenschaftlicher Perspektive insbesondere Auswirkungen auf die Ausprägung individueller und kollektiver Informations-, Wissens- und Kommunikationsprozesse als für die Disziplin relevante Aspekte begreifen. So bereichert das Social Web zentrale Themenfelder wie das Information Retrieval, die Mensch-Maschine-Interaktion oder das Wissensmanagement um neuartige Facetten. Zugleich werden neue Forschungsfelder virulent. Der Artikel skizziert beispielhaft einige dieser Aspekte, die derzeit in Hildesheim, insbesondere mit der neu geschaffenen Juniorprofessur "Social Networks and Collaborative Media", zu einer Erweiterung des informationswissenschaftlichen Lehr- und Forschungsportfolios führen. Ziel des Beitrags ist es zu verdeutlichen, dass die derzeitigen Entwicklungstendenzen des Internets die Bedeutung der Informationswissenschaft als wichtige zukunftsorientierte Lehr- und Forschungsdisziplin unterstreichen und zugleich Chancen und Bedarf für eine offensive Profilierung der Disziplin schaffen.

    Abstract
    The unprecedented growth of the Internet has given rise to the Dark Web, the problematic facet of the Web associated with cybercrime, hate, and extremism. Despite the need for tools to collect and analyze Dark Web forums, the covert nature of this part of the Internet makes traditional Web crawling techniques insufficient for capturing such content. In this study, we propose a novel crawling system designed to collect Dark Web forum content. The system uses a human-assisted accessibility approach to gain access to Dark Web forums. Several URL ordering features and techniques enable efficient extraction of forum postings. The system also includes an incremental crawler coupled with a recall-improvement mechanism intended to facilitate enhanced retrieval and updating of collected content. Experiments conducted to evaluate the effectiveness of the human-assisted accessibility approach and the recall-improvement-based, incremental-update procedure yielded favorable results. The human-assisted approach significantly improved access to Dark Web forums while the incremental crawler with recall improvement also outperformed standard periodic- and incremental-update approaches. Using the system, we were able to collect over 100 Dark Web forums from three regions. A case study encompassing link and content analysis of collected forums was used to illustrate the value and importance of gathering and analyzing content from such online communities.

    Abstract
    Online discussion forums have become a popular medium for users to discuss with and seek information from other users having similar interests. A typical discussion thread consists of a sequence of posts posted by multiple users. Each post in a thread serves a different purpose providing different types of information and, thus, may not be equally useful for all applications. Identifying the purpose and nature of each post in a discussion thread is thus an interesting research problem as it can help in improving information extraction and intelligent assistance techniques. We study the problem of classifying a given post as per its purpose in the discussion thread and employ features based on the post's content, structure of the thread, behavior of the participating users, and sentiment analysis of the post's content. We evaluate our approach on two forum data sets belonging to different genres and achieve strong classification performance. We also analyze the relative importance of different features used for the post classification task. Next, as a use case, we describe how the post class information can help in thread retrieval by incorporating this information in a state-of-the-art thread retrieval model.
