Footnote

Rez. in: JASIST 57(2006) no.8, S.1130-1132 (S.R. Tompson): "The editors of This text in MIT Press' Digital Libraries and Electronic Publishing series deliberately view digital libraries (DLs) as "sociotechnical systems" - "networks of technology. information. documents, people and practices''. They allow an additional definition of "sociotechnical" as "an analytical stance that privileges neither the social nor the technological and in which neither is reducible to the other". This is an important definition, as it is the foundation of the contributors' sociological approach to digital libraries, an approach not typical of the DL literature which still focuses "largely on the technology itself". Bishop et al. have two stated goals for this volume: 1. "... to inform police and professional practice in DLs with socially grounded understanding of DLs as part of a web of social relations and practices. 2. "... to perform technically informed social analysis of phenomena of interest to social scientists that are highlighted by digital libraries. specifically issues of work, groups, and knowledge"."

Abstract

Text mining applications have experienced tremendous advances because of web 2.0 and social networking applications. Recent advances in hardware and software technology have lead to a number of unique scenarios where text mining algorithms are learned. Mining Text Data introduces an important niche in the text analytics field, and is an edited volume contributed by leading international researchers and practitioners focused on social networks & data mining. This book contains a wide swath in topics across social networks & data mining. Each chapter contains a comprehensive survey including the key research content on the topic, and the future directions of research in the field. There is a special focus on Text Embedded with Heterogeneous and Multimedia Data which makes the mining process much more challenging. A number of methods have been designed such as transfer learning and cross-lingual mining for such cases. Mining Text Data simplifies the content, so that advanced-level students, practitioners and researchers in computer science can benefit from this book. Academic and corporate libraries, as well as ACM, IEEE, and Management Science focused on information security, electronic commerce, databases, data mining, machine learning, and statistics are the primary buyers for this reference book.

Abstract

Libraries have always been an inspiration for the standards and technologies developed by semantic web activities. However, except for the Dublin Core specification, semantic web and social networking technologies have not been widely adopted and further developed by major digital library initiatives and projects. Yet semantic technologies offer a new level of flexibility, interoperability, and relationships for digital repositories. Kruk and McDaniel present semantic web-related aspects of current digital library activities, and introduce their functionality; they show examples ranging from general architectural descriptions to detailed usages of specific ontologies, and thus stimulate the awareness of researchers, engineers, and potential users of those technologies. Their presentation is completed by chapters on existing prototype systems such as JeromeDL, BRICKS, and Greenstone, as well as a look into the possible future of semantic digital libraries. This book is aimed at researchers and graduate students in areas like digital libraries, the semantic web, social networks, and information retrieval. This audience will benefit from detailed descriptions of both today's possibilities and also the shortcomings of applying semantic web technologies to large digital repositories of often unstructured data.

Abstract

Recent technological progress in computer science, Web technologies, and constantly evolving information available on the Internet has drastically changed the landscape of search and access to information. Web search has significantly evolved in recent years. In the beginning, web search engines such as Google and Yahoo! were only providing search service over text documents. Aggregated search was one of the first steps to go beyond text search, and was the beginning of a new era for information seeking and retrieval. These days, new web search engines support aggregated search over a number of vertices, and blend different types of documents (e.g., images, videos) in their search results. New search engines employ advanced techniques involving machine learning, computational linguistics and psychology, user interaction and modeling, information visualization, Web engineering, artificial intelligence, distributed systems, social networks, statistical analysis, semantic analysis, and technologies over query sessions. Documents no longer exist on their own; they are connected to other documents, they are associated with users and their position in a social network, and they can be mapped onto a variety of ontologies. Similarly, retrieval tasks have become more interactive and are solidly embedded in a user's geospatial, social, and historical context. It is conjectured that new breakthroughs in information retrieval will not come from smarter algorithms that better exploit existing information sources, but from new retrieval algorithms that can intelligently use and combine new sources of contextual metadata.
With the rapid growth of web-based applications, such as search engines, Facebook, and Twitter, the development of effective and personalized information retrieval techniques and of user interfaces is essential. The amount of shared information and of social networks has also considerably grown, requiring metadata for new sources of information, like Wikipedia and ODP. These metadata have to provide classification information for a wide range of topics, as well as for social networking sites like Twitter, and Facebook, each of which provides additional preferences, tagging information and social contexts. Due to the explosion of social networks and other metadata sources, it is an opportune time to identify ways to exploit such metadata in IR tasks such as user modeling, query understanding, and personalization, to name a few. Although the use of traditional metadata such as html text, web page titles, and anchor text is fairly well-understood, the use of category information, user behavior data, and geographical information is just beginning to be studied. This book is intended for scientists and decision-makers who wish to gain working knowledge about search engines in order to evaluate available solutions and to dialogue with software and data providers.

Nayar): "The network society (Castells, 1996) calls for radically new definitions of the public sphere. and this is what Shaping the Network Society's essays set out to do. The first section lays out the essential issues at stake here: human rights, the sociology of cyberspace. and globalization. Oliver BoydBarrett characterizes cyberspace as exclusive. Pointing to the almost total corporate control of the technologies of cyberspace. Boyd-Barrett argues that any attempt of huge corporate bodies to get into grassroots democracy should be viewed with suspicion. The institution of a public sphere. argues Boyd-Barrett, must begin with an assessment of how far the Internet at fords a space of contestation of elitist governing frameworks. Gary Chapman looks at Italy's slow food movement as a counter to the technoglobalist trends, and suggests that the globaltechnological imperative must not be allowed to occlude human values. Rather we need a social imperative here. one which thinks about technology as "malleable, as capable of serving human-determined ends" (p. 64). Cees Hamelink discusses how four rights-right to speech. democratic order, equal participation in social life. and cultural identity are threatened by what he terms the billboardization of society in the networked age. In the second section a range of case studies are presented. Kate Williams and Abdul Alkalimat survey every public computing facility in Toledo (Ohio) to map the parameters of public access to information and decision-making. They conclude that government public computing sites arc situated randomly, community sites are in economically rich or poor (but not middle-stratum) localities, and that commercial and university sites are influenced by market forces. They suggest that future research must necessarily focus on what forms of cyberpower emerge through such use of public computing.
Geert Lovnik and Patrice Riemens explore the digital culture of Amsterdam to show how. despite the techno-social idealism of the early years of the public sphere Digital City project. the culture ran into problems. Susan Finquelievich studies the practices of civic networks in Buenos Aires and Montevideo to demonstrate how local sociohistorical conditions have shaped the technology's development. Veran Matic focuses on the role of media in defending human rights in a hostile environment (former Yugoslavia). Media, she notes, need not necessarily he (or become) a tool of fascist forces, but can he used to generate resistance and to forge a democratic public sphere. Scott Robinson looks at Mexico's telecenter movement to argue that these cybercafes are likely to become an institution for the new Second World of immigrants and refugees. through socially relevant functions. Fiorella de Cindio looks at one of the worlds most significant community networks that of Milan. She demonstrates how local citizens have used information and communication technologies to build a viable. and potentially empowering, participatory public sphere in academia, computer-supported cooperative work, participatory design, and civil engagement (what she calls genes). The third section, -'Building a New Public Sphere in Cyberspace," pros- ides a series of suggestions and frameworks for the spacing of public space through information and communications technologies. Craig Calhoun argues that a global public sphere is indispensable to the formation of a global democracy. Public discourse can still fight commercialism and violence to form a more democratic civil society. Howard Rheingold the great enthusiast of virtual worlds-performs an intricate mix of autobiographical reflection and speculation when he writes of the role of the new technologies. Rheingold, despite his fetishistic enthusiasm for technology and online community, is cautious when it comes to crucial issues such as the creation of democratic public spheres, arguing that we require a great deal more serious thinking on matters of ownership and control (over the technology). He argues that if citizens lose our freedom to communicate, then even the powerful potential of the Net to create electronic democracy will be fatal illusion (p. 275). Nancy Kranich turns to public libraries as the site of potential democratic society, arguing that as sites of informationdissemination. public libraries can become a commons for the exchange of ideas and social interaction. David Silver compares the Blacksburg Electronic Village (BEV) to the Seattle Community Network the former funded by corporations and the state, the latter built essentially out of and through volunteer efforts. Silver, in characteristic style. looks at the historical archaeologies of the networks to show how sociohistorical contexts shape certain kinds of public spheres (and public discourse). going on to ask how, these networks can overcome these contexts to achieve their original goals. He warns that we need to uncover the histories of such networks because they inform the kinds of interactions of communities that exist within them. Douglas Morris analyzes the Independent Media Centre (IMO) Movement of antiglobalization activists to argue that alternative viewpoints and ideological differences can he aired, debated, and appropriated through the new technologies in order to fight corporate and commercial forces.
Peter Day and Douglas Schuler wind up the book by taking a close look at the sociotechnical context in the 1990s. They argue that utopian schemes for the development of civil society and/or the public sphere may entail a degree of risk. However. Day and Schuler argue that community networks should be ''networks of awareness. advocacy and action" with a high degree of grassroots involvement. This can be done through more responsive policies. Local citizens-the first beneficiaries or victims of policy-should he brought into the decision-making process via civic dialogue. Public funding must be provided for projects that enable dissemination of information about a variety of cultures and belief systems. Shaping the Network Society is understandably more cautious than earlier accounts of cyberculture in its reception of new information and communications technology. Haunted by post 9/11 security measures. increasing surveillance, the faster erosion of liberal humanist ideals, and the internationalization/ commercialization of the media, the essays prefer to be wary about the potential of cyberpower. However, the optimist tone of every essay is unmistakable. While admitting that much more needs to be done to overcome the digital divide and the (mis)appropriation of cyberpower. the essays and ease studies draw attention to the potential for public debate and alternative ideologies. The case studies demonstrate success stories, but invariably conclude with a moral: about the need for vigilance against appropriation and fascist control! What emerges clearly is that the new media have achieved considerable progress in opening up the space for greater citizen involvement, more locally-responsive policy decisions. and socially relevant information-dissemination. Shaping the Network Society, with a strangely messianic slant, is a useful step in the mapping of the present and future cyberspace as the space of new democracies to come of a justice to he worked and prepared for."

Abstract

The Internet has been integral to the globalization of a range of goods and production, from intellectual property and scientific research to political discourse and cultural symbols. Yet the ease with which it allows information to flow at a global level presents enormous regulatory challenges. Understanding if, when, and how the law should regulate online, international flows of information requires a firm grasp of past, present, and future patterns of information flow, and their political, economic, social, and cultural consequences.In The Global Flow of Information, specialists from law, economics, public policy, international studies, and other disciplines probe the issues that lie at the intersection of globalization, law, and technology, and pay particular attention to the wider contextual question of Internet regulation in a globalized world. While individual essays examine everything from the pharmaceutical industry to television to "information warfare" against suspected enemies of the state, all contributors address the fundamental question of whether or not the flow of information across national borders can be controlled, and what role the law should play in regulating global information flows.

Abstract

Metadata is a key aspect of our evolving infrastructure for information management, social computing, and scientific collaboration. DC-2008 will focus on metadata challenges, solutions, and innovation in initiatives and activities underlying semantic and social applications. Metadata is part of the fabric of social computing, which includes the use of wikis, blogs, and tagging for collaboration and participation. Metadata also underlies the development of semantic applications, and the Semantic Web - the representation and integration of multimedia knowledge structures on the basis of semantic models. These two trends flow together in applications such as Wikipedia, where authors collectively create structured information that can be extracted and used to enhance access to and use of information sources. Recent discussion has focused on how existing bibliographic standards can be expressed as Semantic Web vocabularies to facilitate the ingration of library and cultural heritage data with other types of data. Harnessing the efforts of content providers and end-users to link, tag, edit, and describe their information in interoperable ways ("participatory metadata") is a key step towards providing knowledge environments that are scalable, self-correcting, and evolvable. DC-2008 will explore conceptual and practical issues in the development and deployment of semantic and social applications to meet the needs of specific communities of practice.
