Big Data, Little Data, No Data
\"Big Data\" is on the covers ofScience, Nature, theEconomist, andWiredmagazines, on the front pages of theWall Street Journaland theNew York Times.But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines.Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six \"provocations\" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.

Information Retrieval
Deep learning and word embeddings have made significant impacts on information retrieval (IR) by adding techniques based in neural networks and language models. This book, written by international academic and industry experts, brings the field up to date with detailed discussions of new approaches and techniques.

Handbook of evaluation methods for health informatics
This Handbook provides a complete compendium of methods for evaluation of IT-based systems and solutions within healthcare. Emphasis is entirely on assessment of the IT-system within its organizational environment. The author provides a coherent and complete assessment of methods addressing interactions with and effects of technology at the organizational, psychological, and social levels.It offers an explanation of the terminology and theoretical foundations underlying the methodological analysis presented here. The author carefully guides the reader through the process of identifying relevant methods corresponding to specific information needs and conditions for carrying out the evaluation study. The Handbook takes a critical view by focusing on assumptions for application, tacit built-in perspectives of the methods as well as their perils and pitfalls. *Collects a number of evaluation methods of medical informatics*Addresses metrics and measures*Includes an extensive list of anotated references, case studies, and a list of useful Web sites

Informatica
Informatica -the updated
edition of Alex Wright's previously published Glut-continues the
journey through the history of the information age to show how
information systems emerge . Today's \"information
explosion\" may seem like a modern phenomenon, but we are not the
first generation-or even the first species-to wrestle with the
problem of information overload. Long before the advent of
computers, human beings were collecting, storing, and organizing
information: from Ice Age taxonomies to Sumerian archives, Greek
libraries to Christian monasteries.
Wright weaves a narrative that connects such seemingly far-flung
topics as insect colonies, Stone Age jewelry, medieval monasteries,
Renaissance encyclopedias, early computer networks, and the World
Wide Web. He suggests that the future of the information age may
lie deep in our cultural past.
We stand at a precipice struggling to cope with a tsunami of
data. Wright provides some much-needed historical perspective. We
can understand the predicament of information overload not just as
the result of technological change but as the latest chapter in an
ancient story that we are only beginning to understand.

Bridging Digital Divides: a Literature Review and Research Agenda for Information Systems Research
Extant literature has increased our understanding of the multifaceted nature of the digital divide, showing that it entails more than access to information and communication resources. Research indicates that digital inequality mirrors to a significant extent offline inequality related to socioeconomic resources. Bridging digital divides is critical for sustainable digitalized societies. Ιn this paper, we present a literature review of Information Systems research on the digital divide within settings with advanced technological infrastructures and economies over the last decade (2010–2020). The review results are organized in a concept matrix mapping contributing factors and measures for crossing the divides. Building on the results, we elaborate a research agenda that proposes [1] extending established models of digital inequalities with new variables and use of theory, [2] critically examining the effects of digital divide interventions, and [3] better linking digital divide research with research on sustainability.
