    Abstract
    Classification and the organization of information are directly connected to issues surrounding social justice, diversity, and inclusion. This paper is written from the standpoint that political and epistemological aspects of knowledge organization are fundamental to research and practice and suggests ways to integrate social justice and diversity issues into courses on the organization of information.

    Abstract
    Um .Zehn Gründe.... zu lesen, reicht ein einziger Grund: Jaron Lanier. Am wichtigsten Mahner vor Datenmissbrauch, Social-Media-Verdummung und der fatalen Umsonst-Mentalität im Netz führt in diesen Tagen kein Weg vorbei. Frank Schätzing Ein Buch, das jeder lesen muss, der sich im Netz bewegt. Jaron Lanier, Tech-Guru und Vordenker des Internets, liefert zehn bestechende Gründe, warum wir mit Social Media Schluss machen müssen. Facebook, Google & Co. überwachen uns, manipulieren unser Verhalten, machen Politik unmöglich und uns zu ekligen, rechthaberischen Menschen. Social Media ist ein allgegenwärtiger Käfig geworden, dem wir nicht entfliehen können. Lanier hat ein aufrüttelndes Buch geschrieben, das seine Erkenntnisse als Insider des Silicon Valleys wiedergibt und dazu anregt, das eigenen Verhalten in den sozialen Netzwerken zu überdenken. Wenn wir den Kampf mit dem Wahnsinn unserer Zeit nicht verlieren wollen, bleibt uns nur eine Möglichkeit: Löschen wir all unsere Accounts!

    Abstract
    The social dynamics of alternative facts: why what you believe depends on who you know. Why should we care about having true beliefs? And why do demonstrably false beliefs persist and spread despite bad, even fatal, consequences for the people who hold them? Philosophers of science Cailin OConnor and James Weatherall argue that social factors, rather than individual psychology, are whats essential to understanding the spread and persistence of false beliefs. It might seem that theres an obvious reason that true beliefs matter: false beliefs will hurt you. But if thats right, then why is it (apparently) irrelevant to many people whether they believe true things or not? The Misinformation Age, written for a political era riven by fake news, alternative facts, and disputes over the validity of everything from climate change to the size of inauguration crowds, shows convincingly that what you believe depends on who you know. If social forces explain the persistence of false belief, we must understand how those forces work in order to fight misinformation effectively.

    Abstract
    Purpose - The purpose of this paper is to explore the potential of applying the Dewey Decimal Classification (DDC) as an established knowledge organization system (KOS) for enhancing social tagging, with the ultimate purpose of improving subject indexing and information retrieval. Design/methodology/approach - Over 11.000 Intute metadata records in politics were used. Totally, 28 politics students were each given four tasks, in which a total of 60 resources were tagged in two different configurations, one with uncontrolled social tags only and another with uncontrolled social tags as well as suggestions from a controlled vocabulary. The controlled vocabulary was DDC comprising also mappings from the Library of Congress Subject Headings. Findings - The results demonstrate the importance of controlled vocabulary suggestions for indexing and retrieval: to help produce ideas of which tags to use, to make it easier to find focus for the tagging, to ensure consistency and to increase the number of access points in retrieval. The value and usefulness of the suggestions proved to be dependent on the quality of the suggestions, both as to conceptual relevance to the user and as to appropriateness of the terminology. Originality/value - No research has investigated the enhancement of social tagging with suggestions from the DDC, an established KOS, in a user trial, comparing social tagging only and social tagging enhanced with the suggestions. This paper is a final reflection on all aspects of the study.

    Abstract
    Since the middle of the last century knowledge organization, the development of scientific concepts and arrangements, has been seen as a cognitivistic (or rationalistic) problem and thus as universal and logical (cf. Turing 1950). Older approaches accordingly see areas of knowledge as naturally given and organically grown. The knowledge must only be detected and logically arranged. At latest with the constructivism a 'turn' has entered, which sees knowledge organization as a social convention and accordingly regards universal standards skeptical. Simultaneously in the sciences came up a stronger concern with historical, empirical and sociological studies of its foundations and in philosophy of science the return to different kinds of relativizations has gained more importance. With the challenge of self-organizing ordering systems by social software a new crisis comes up for knowledge organization. The future might be a combination of logical descriptions, specialized evaluation, and accompanying user-driven principles. In this paper, several classical sociological positions are discussed, conclusions are drawn for knowledge and information as well as for science and for knowledge organization and objections and prospects are designated.

    Abstract
    As the Internet becomes ubiquitous, it has advanced to more closely represent aspects of the real world. Due to this trend, researchers in various disciplines have become interested in studying relationships between real-world phenomena and their virtual representations. One such area of emerging research seeks to study relationships between real-world and virtual activism of social movement organization (SMOs). In particular, SMOs holding extreme social perspectives are often studied due to their tendency to have robust virtual presences to circumvent real-world social barriers preventing information dissemination. However, many previous studies have been limited in scope because they utilize manual data-collection and analysis methods. They also often have failed to consider the real-world aspects of groups that partake in virtual activism. We utilize automated data-collection and analysis methods to identify significant relationships between aspects of SMO virtual communities and their respective real-world locations and ideological perspectives. Our results also demonstrate that the interconnectedness of SMO virtual communities is affected specifically by aspects of the real world. These observations provide insight into the behaviors of SMOs within virtual environments, suggesting that the virtual communities of SMOs are strongly affected by aspects of the real world.

    Abstract
    A new collaborative approach in information organization and sharing has recently arisen, known as collaborative tagging or social indexing. A key element of collaborative tagging is the concept of collective intelligence (CI), which is a shared intelligence among all participants. This research investigates the phenomenon of social tagging in the context of CI with the aim to serve as a stepping-stone towards the mining of truly valuable social tags for web resources. This study focuses on assessing and evaluating the degree of CI embedded in social tagging over time in terms of two-parameter values, number of participants, and top frequency ranking window. Five different metrics were adopted and utilized for assessing the similarity between ranking lists: overlapList, overlapRank, Footrule, Fagin's measure, and the Inverse Rank measure. The result of this study demonstrates that a substantial degree of CI is most likely to be achieved when somewhere between the first 200 and 400 people have participated in tagging, and that a target degree of CI can be projected by controlling the two factors along with the selection of a similarity metric. The study also tests some experimental conditions for detecting social tags with high CI degree. The results of this study can be applicable to the study of filtering social tags based on CI; filtered social tags may be utilized for the metadata creation of tagged resources and possibly for the retrieval of tagged resources.

    Abstract
    In Digital Methods, Richard Rogers proposes a methodological outlook for social and cultural scholarly research on the Web that seeks to move Internet research beyond the study of online culture. It is not a toolkit for Internet research, or operating instructions for a software package; it deals with broader questions. How can we study social media to learn something about society rather than about social media use? How can hyperlinks reveal not just the value of a Web site but the politics of association? Rogers proposes repurposing Web-native techniques for research into cultural change and societal conditions. We can learn to reapply such "methods of the medium" as crawling and crowd sourcing, PageRank and similar algorithms, tag clouds and other visualizations; we can learn how they handle hits, likes, tags, date stamps, and other Web-native objects. By "thinking along" with devices and the objects they handle, digital research methods can follow the evolving methods of the medium. Rogers uses this new methodological outlook to examine the findings of inquiries into 9/11 search results, the recognition of climate change skeptics by climate-change-related Web sites, the events surrounding the Srebrenica massacre according to Dutch, Serbian, Bosnian, and Croatian Wikipedias, presidential candidates' social media "friends," and the censorship of the Iranian Web. With Digital Methods, Rogers introduces a new vision and method for Internet research and at the same time applies them to the Web's objects of study, from tiny particles (hyperlinks) to large masses (social media).

    Abstract
    Purpose The purpose of this paper is to examine participation in online social platforms consisting of information exchange, social network interactions, and political deliberation. Despite the proven benefits of online participation, the majority of internet users read social media data but do not directly contribute, a phenomenon called lurking. Design/methodology/approach A survey was administered electronically to 507 participants and consisted of ten sections in a questionnaire to gather data on the relationship between online participation and the following variables: anonymity, social value orientation, motivations, and participation in offline activities, as well as the internet's political influence and personality traits. Findings Findings show that users with high levels of participation also identify themselves, report higher levels of extroversion, openness, and activity outside the internet, the motivations being an intermediary variable in the relationship between the variables value. Originality/value The study shows that participation in online social platforms is not only related to personality traits, but they are impacted by the nature of the motivations that drive them to participate in the particular social platform, as well as by the interest toward the specific topic, or the type or nature of the social group with whom they are communicating.

    Abstract
    With the proliferation of huge amounts of (heterogeneous) data on the Web, the importance of information retrieval (IR) has grown considerably over the last few years. Big players in the computer industry, such as Google, Microsoft and Yahoo!, are the primary contributors of technology for fast access to Web-based information; and searching capabilities are now integrated into most information systems, ranging from business management software and customer relationship systems to social networks and mobile phone applications. Ceri and his co-authors aim at taking their readers from the foundations of modern information retrieval to the most advanced challenges of Web IR. To this end, their book is divided into three parts. The first part addresses the principles of IR and provides a systematic and compact description of basic information retrieval techniques (including binary, vector space and probabilistic models as well as natural language search processing) before focusing on its application to the Web. Part two addresses the foundational aspects of Web IR by discussing the general architecture of search engines (with a focus on the crawling and indexing processes), describing link analysis methods (specifically Page Rank and HITS), addressing recommendation and diversification, and finally presenting advertising in search (the main source of revenues for search engines). The third and final part describes advanced aspects of Web search, each chapter providing a self-contained, up-to-date survey on current Web research directions. Topics in this part include meta-search and multi-domain search, semantic search, search in the context of multimedia data, and crowd search. The book is ideally suited to courses on information retrieval, as it covers all Web-independent foundational aspects. Its presentation is self-contained and does not require prior background knowledge. It can also be used in the context of classic courses on data management, allowing the instructor to cover both structured and unstructured data in various formats. Its classroom use is facilitated by a set of slides, which can be downloaded from www.search-computing.org.

    Abstract
    Online communities are becoming an important tool in the communication and participation processes in our society. However, the most widespread applications are difficult to use for people with disabilities, or may involve some risks if no previous training has been undertaken. This work describes a novel social network for cognitively disabled people along with a clustering-based method for modeling activity and socialization processes of its users in a noninvasive way. This closed social network is specifically designed for people with cognitive disabilities, called Guremintza, that provides the network administrators (e.g., social workers) with two types of reports: summary statistics of the network usage and behavior patterns discovered by a data mining process. Experiments made in an initial stage of the network show that the discovered patterns are meaningful to the social workers and they find them useful in monitoring the progress of the users.

    Abstract
    Encouraging users of social network sites (SNS) to actively provide personal information is vital if SNS are to prosper, but privacy concerns have hindered users from giving such information. Previous research dealing with privacy concerns has studied mostly worries about information misuse, focusing on the protection aspects of privacy. By adopting an interpersonal conception of privacy and communication privacy management theory, this study offers a new way of understanding privacy concerns by examining the social and presentational aspects of privacy. It examines privacy concerns in terms not only of others' misuse but of others' misunderstanding and personal information in terms not only of identity but of self-presentational information. Furthermore, it investigates the ways in which information and social risks inherent in SNS influence privacy concerns. A structural equation modeling analysis of a cross-sectional survey of 396 Facebook users finds that longer usage does not alleviate the impact of information risk on either concern, that a greater proportion of offline friends among one's SNS friends aggravates the impact of social risk on both concerns, and that concerns about information misuse affect the provision only of identity information, whereas concerns about information misunderstanding affect the provision of both identity and self-presentational information.

    Abstract
    Purpose - The purpose of this paper is to examine how keeping the records of social networking sites (SNS) communication for secondary analysis institutes a new type of memory practice, one that seeks both to capture shared public memories and form new cultural understandings. Design/methodology/approach - Using a framework of documentary and memory practices the study conducts a qualitative content analysis of SNS communications collected from Facebook, GooglePlus and Twitter during a national event. It combines a content analysis of the communications with the analysis of their materiality and form to investigate potential contributions of SNS to social and cultural memory including their subsequent custodianship. Findings - The study finds that the message architecture and metadata of different social networks is comparable and collectively evidences differing aspects of social events to document their unique discourse. Findings demonstrate the contribution SNS is making to social memory and a framework for understanding how SNS in being incorporated into cultural memory practice is presented. Originality/value - This is one of the few studies that analyses a range of messages from differing SNS in order to understand their impact on cultural memory and the documentary practices of memory institutions.

    Abstract
    Documentary activities are informational operations of selection and representation of objects made from their features and predictable use. In order to make them more dynamic, these activities are carried out systemically, according to institutionally limited (in the sense of social institution) information projects. This organic approach leads to the constitution of information systems, or, more specifically, systems of documentary information, inasmuch as they refer to actions about documents as objects from which information is produced. Thus, systems of documentary information are called documentary systems. This article aims to list and systematize elements with the potential to a generalizing and categorical approach of documentary systems. We approach the systems according to: elements of reference (the documents and their information, the users, and the institutional context); constitutive elements (collection and references); structural elements (constituent units and the relation among them); modes of production (pre or post representation of the document); management aspects (flow of documents and of their information); and, finally, typology (management systems and information retrieval systems). Thus, documentary systems can be considered products due to operations involving objects institutionally limited for the production of collections (virtual or not) and their references, whose objective is the appropriation of information by the user.

    Abstract
    The purpose of this study was to examine user tags that describe digitized archival collections in the field of humanities. A collection of 8,310 tags from a digital portal (Nineteenth-Century Electronic Scholarship, NINES) was analyzed to find out what attributes of primary historical resources users described with tags. Tags were categorized to identify which tags describe the content of the resource, the resource itself, and subjective aspects (e.g., usage or emotion). The study's findings revealed that over half were content-related; tags representing opinion, usage context, or self-reference, however, reflected only a small percentage. The study further found that terms related to genre or physical format of a resource were frequently used in describing primary archival resources. It was also learned that nontextual resources had lower numbers of content-related tags and higher numbers of document-related tags than textual resources and bibliographic materials; moreover, textual resources tended to have more user-context-related tags than other resources. These findings help explain users' tagging behavior and resource interpretation in primary resources in the humanities. Such information provided through tags helps information professionals decide to what extent indexing archival and cultural resources should be done for resource description and discovery, and understand users' terminology.

    Abstract
    Since natural disasters can affect many people over a vast area, studying information-seeking behavior (ISB) during disasters is of great importance. Many previous studies have relied on online social network data, providing insights into the ISB of those with Internet access. However, in a large-scale natural disaster such as the Great East Japan Earthquake of 2011, people in the most severely affected areas tended to have limited Internet access. Therefore, an alternative data source should be explored to investigate disaster-related ISB. This study's contributions are twofold. First, we provide a detailed description of natural disaster-related ISB of people who experienced a large-scale earthquake and tsunami, based on analysis of written testimonies published by local authorities. This provided insight into the relationship between information needs, channels, and sources of disaster-related ISB. Also, our approach facilitates the study of ISB of people without Internet access both during and after a disaster. Second, we provide empirical evidence to demonstrate that the temporal stages of a disaster can characterize people's ISB during the disaster. Therefore, we propose further consideration of the temporal aspects of events for improved understanding of disaster-related ISB.

    Abstract
    The article discusses various aspects of the Dewey Decimal Classification (DDC) system of classifying library books in 2013. Background is presented on some librarians' desire to stop using DDC and adopt a genre-based system of classification. It says librarians can use the DDC to deal with problems and issues related to library book classification. It highlights the benefits of using captions and relative index terms and semantic relationships in DDC.

    "As knowledge brokers, we are living in interesting times for libraries and librarians. We wonder sometimes if our traditional tools like the Dewey Decimal Classification (DDC) system can cope with the onslaught of information. The categories provided don't always seem adequate for the knowledge-discovery habits of today's patrons. They have grown accustomed to new ways for their information needs to be met, from the fire-and-forget style of a hard-to-control classic Google search to the pervasive, always-on style of Google Now, anticipating users' information needs without their having even asked a verbal question. Contrariwise, I believe that we, as librarians, could be making better use of our tools. Many (like the DDC) are a reflection of the same social and epistemological forces that brought about modernity at the turn of the last century. We as librarians are in the unique position of providing services that are as ground-breaking as these tools. As we see the need to provide unique and cutting-edge knowledge discovery to our users, I argue in this article that the DDC can play a key role in fulfilling this purpose."

    Abstract
    Purpose Online knowledge communities make great contributions to global knowledge sharing and innovation. Resource tagging approaches have been widely adopted in such communities to describe, annotate and organize knowledge resources mainly through users' participation. However, it is unclear what causes the adoption of a particular resource tagging approach. The purpose of this paper is to identify factors that drive users to use a hybrid social tagging approach. Design/methodology/approach Technology acceptance model and social cognitive theory are adopted to support an integrated model proposed in this paper. Zhihu, one of the most popular online knowledge communities in China, is taken as the survey context. A survey was conducted with a questionnaire and collected data were analyzed through structural equation model. Findings A new hybrid social resource tagging approach was refined and described. The empirical results revealed that self-efficacy, perceived usefulness (PU) and perceived ease of use exert positive effect on users' attitude. Moreover, social influence, PU and attitude impact significantly on users' intention to use a hybrid social resource tagging approach. Originality/value Theoretically, this study enriches the type of resource tagging approaches and recognizes factors influencing user adoption to use it. Regarding the practical parts, the results provide online information system providers and designers with referential strategies to improve the performance of the current tagging approaches and promote them.

    Abstract
    Purpose The purpose of this paper is to examine some drivers of users' participation in online social question-and-answer (Q&A) communities based on social cognitive theory and then identify the underlying mechanism of this process. Design/methodology/approach This study developed a research model to test the proposed hypotheses, and an online survey was employed to collected data. Totally, 313 valid responses were collected, and partial least squares structural equation modeling was adopted to analyze these data. Findings This study empirically finds that the outcome expectations (personal outcome expectations and knowledge self-management outcome expectations) are positively related to participation in online social Q&A communities. At the same time, users' self-efficacy positively influences their participation behaviors. It can not only directly motivate users' participation, but also indirectly promote participation behaviors through the two dimensions of outcome expectations. Besides, perceived expertise and perceived similarity are two positive and significant environmental elements affecting users' participation. Originality/value This study extends the understanding about how participation behaviors will be motivated in the context of online social Q&A communities. Drawing on the social cognitive theory, constructs were established based on the features of these communities. Meanwhile, some mediating effects in the motivating process were also discussed.
