The death of Web 2.0 : ethics, connectivity and recognition in the twenty-first century
\"Communication in today's world is characterised by a condition of persistent, semi-permanent connectivity, which seems to bring us closer together but which can also be profoundly alienating. The Death of Web 2.0 takes a retrospective look at a moment in recent media history that has had, and will continue to have, a lasting impact upon the predominant attitude towards cultures of connectivity. Greg Singh draws from a range of approaches, intellectual traditions and scholarly disciplines to engage key questions underpinning the contemporary communications media ecosystem\"-- Provided by publisher.

Folksonomies. Indexing and Retrieval in Web 2.0
In Web 2.0 users not only make heavy use of Col-laborative Information Services in order to create, publish and share digital information resources - what is more, they index and represent these re-sources via own keywords, so-called tags. The sum of this user-generated metadata of a Collaborative Information Service is also called Folksonomy. In contrast to professionally created and highly struc-tured metadata, e.g. subject headings, thesauri, clas-sification systems or ontologies, which are applied in libraries, corporate information architectures or commercial databases and which were developed according to defined standards, tags can be freely chosen by users and attached to any information resource. As one type of metadata Folksonomies provide access to information resources and serve users as retrieval tool in order to retrieve own re-sources as well as to find data of other users.
The book delivers insights into typical applications of Folksonomies, especially within Collaborative Information Services, and discusses the strengths and weaknesses of Folksonomies as tools of knowl-edge representation and information retrieval. More-over, it aims at providing conceptual considerations for solving problems of Folksonomies and presents how established methods of knowledge representa-tion and models of information retrieval can successfully be transferred to them.

Making is connecting : the social power of creativity, from craft and knitting to digital everything
\"SECOND UPDATED EDITION, WITH THREE ALL-NEW CHAPTERS The first edition ofMaking is Connectingstruck a chord with crafters, YouTubers, makers, music producers, artists and coders alike. David Gauntlett argues that through making things, people engage with the world and create connections with each other. Online and offline, we see that people want to make their mark, and to make connections. This shift from a sit-back-and-be-told culture to a making-and-doing culture means that a vast array of people are exchanging their own ideas, videos, and other creative material online, as well as engaging in real-world crafts, music projects, and hands-on experiences. Drawing on evidence from psychology, politics, philosophy, and economics, Gauntlett shows that this everyday creative engagement is necessary and essential for the happiness and survival of modern societies. This fully revised second edition includes many new sections as well as three brand new chapters on creative processes, do-it-yourself strategies, and platforms for creativity\"-- Provided by publisher.

Information Retrieval
This book is an essential reference to cutting-edge issues and future directions in information retrieval Information retrieval (IR) can be defined as the process of representing, managing, searching, retrieving, and presenting information. Good IR involves understanding information needs and interests, developing an effective search technique, system, presentation, distribution and delivery. The increased use of the Web and wider availability of information in this environment led to the development of Web search engines. This change has brought fresh challenges to a wider variety of users’ needs, tasks, and types of information. Today search engines are seen in enterprises, on laptops, in individual websites, in library catalogues, and elsewhere. Information Retrieval: Searching in the 21st Century Information Retrieval Focuses on: •Information Retrieval Models •User-centred Evaluation of Information Retrieval Systems •Multimedia Resource Discovery •Image Users’ Needs and Searching Behaviour •Web Information Retrieval •Mobile Search •Context and Information Retrieval •Text Categorisation and Genre in Information Retrieval •Semantic Search •The Role of Natural Language Processing in Information Retrieval: Search for Meaning and Structure •Cross-language Information Retrieval •Performance Issues in Parallel Computing for Information Retrieval This book is an invaluable reference for graduate students on IR courses or courses in related disciplines (e.g. computer science, information science, human-computer interaction, and knowledge management), academic and industrial researchers, and industrial personnel tracking information search technology developments to understand the business implications. Intermediate-advanced level undergraduate students on IR or related courses will also find this text insightful. Chapters are supplemented with exercises to stimulate further thinking.

Behind the Screen
An eye-opening look at the invisible workers who protect us from seeing humanity's worst on today's commercial internetSocial media on the internet can be a nightmarish place. A primary shield against hateful language, violent videos, and online cruelty uploaded by users is not an algorithm. It is people. Mostly invisible by design, more than 100,000 commercial content moderators evaluate posts on mainstream social media platforms: enforcing internal policies, training artificial intelligence systems, and actively screening and removing offensive material-sometimes thousands of items per day. Sarah T. Roberts, an award-winning social media scholar, offers the first extensive ethnographic study of the commercial content moderation industry. Based on interviews with workers from Silicon Valley to the Philippines, at boutique firms and at major social media companies, she contextualizes this hidden industry and examines the emotional toll it takes on its workers. This revealing investigation of the people \"behind the screen\" offers insights into not only the reality of our commercial internet but the future of globalized labor in the digital age.

Interpreting hashtag politics : policy ideas in an era of social media
\"Why do policy actors create branded terms like Big Society and does launching such policy ideas on Twitter extend or curtail their life? This book argues that the practice of hashtag politics has evolved in response to an increasingly congested and mediatised environment, with the recent and rapid growth of high speed internet connections, smart phones and social media. It examines how policy analysis can adapt to offer interpretive insights into the life and death of policy ideas in an era of hashtag politics. This text reveals that policy ideas can at the same time be ideas, instruments, visions, containers and brands, and advises readers on how to tell if a policy idea is dead or dying, how to map the diversity of viewpoints, how to capture the debate, when to engage and when to walk away. Each chapter showcases innovative analytic techniques, illustrated by application to contemporary policy ideas.\"--Publisher's website.

The culture of connectivity : a critical history of social media
This book studies the rise of social media in the first decade of the twenty-first century, up until 2012. It provides both a historical and a critical analysis of the emergence of networking services in the context of a changing ecosystem of connective media. Such history is needed to understand how the intricate constellation of platforms profoundly affects our experience of online sociality. In a short period of time, services like Facebook, YouTube and many others have come to deeply penetrate our daily habits of communication and creative production. While most sites started out as amateur-driven community platforms, half a decade later they have turned into large corporations that do not just facilitate user connectedness, but have become global information and data mining companies extracting and exploiting user connectivity. Offering a dual analytical prism to examine techno-cultural as well as socio-economic aspects of social media, the author dissects five major platforms: Facebook, Twitter, Flickr, YouTube, and Wikipedia. Each of these microsystems occupies a distinct position in the larger ecosystem of connective media, and yet, their underlying mechanisms for coding interfaces, steering users, filtering content, governance and business models rely on shared ideological principles. Reconstructing the premises on which these platforms are built, this study highlights how norms for online interaction and communication gradually changed. “Sharing,” “friending,” “liking,” “following,” “trending,” and “favoriting” have come to denote online practices imbued with specific technological and economic meanings. This process of normalization is part of a larger political and ideological battle over information control in an online world where everything is bound to become “social.”
