The lure of big data and analytics has produced new partnerships between news media and social media and consequently a fragmentation of digital journalism. The era is coupled with the rise in fake news and controversial data sharing. However, creative mobile reporting and civilian drones set new standards for journalist during the European asylum seeker crisis. Yet the focus on data and remote cloud servers continues to dominate online news and journalism, alongside new semantic models for data personalization. News tags that define concepts within a news story to assist search, are now monetized abstractions in accelerated data processing that enables automation and feeds advertising. Can journalism compete with this by defining its own concepts with ethical values named and embedded in algorithms? Can machines make sense of the world in the same way as a traditional journalist? In this book, Cate Dowd analyzes the tasks and ethics of journalists and questions how intelligent machines could simulate ethical human behaviors to better understand the dizzy post-human world of online data. Looking to digital journalism and multi-platform news media, from studios and integrated media systems to mobile reporting in the field, Dowd assesses how data and digital technology has impacted on journalism over the past decade. Dowd's research is informed by in-depth participation with investigative journalists, including images drawn and annotated by industry experts to present key journalism concepts, priorities, and values. Chapters explore approaches for the elicitation of vocabulary for journalism and design methods to embed values and ethics into algorithms for the era of automation and big data. Digital Journalism, Drones, and Automation provides insights into the lasting values of journalism processes and equips readers interested in entering or understanding online data and news media with much needed context and wisdom.

The researcher in computer content analysis is often faced with a paucity of guidance in conducting a study. Published exemplars of best practice in computer content analysis are rare, and computer content analysis seems to have developed independently in a number of disciplines, with researchers in one field often unaware of new and innovative techniques developed by researchers in other areas. This volume contains numerous articles illustrating the current state of the art of computer content analysis. Research is presented by scholars in political science, natural resource management, mass communication, marketing, education, and other fields, with the aim of providing exemplars for further research on the computer analysis and understanding of textual materials. The studies presented in "Applications of Computer Content Analysis" offer a varied spectrum of exemplary studies, Researchers can, due to the breadth of the studies presented here, find methodological, theoretical, and practical suggestions which will significantly ease the process of creating new research--and will significantly reduce the duplication of effort which has, until now, plagued computer content analytic research. Intended for an audience of graduate students, scholars, and in-field practitioners, this will serve as an invaluable resource, full of useful examples, for those interesting in using computers to analyze newspapers articles, emails, mediated communication, or any other sort of digital communication.

process, from requirements analysis to schema generation. You'll
learn to express stakeholder needs in UML use cases and actor
diagrams, to translate UML entities into database components, and
to transform the resulting design into relational,
object-relational, and object-oriented schemas for all major DBMS
products.
This is an introductory textbook in data analysis and statistics, designed for students in the first year of a social sciences degree. The key concepts of data analysis are explained in a clear and straightforward manner, avoiding unnecessary jargon. Very little mathematical knowledge is assumed on the part of the reader, and a variety of examples are used to illustrate the ideas and techniques. One of the central aims of the text is to ensure that students understand the basic principles of exploratory data analysis before they become involved in manipulating large quantities of data. Hence the author generally uses small data sets to introduce the key concepts, and gradually moves towards the handling of larger data sets. The text uses the Minitab computer analysis package, which is one of the most popular statistical packages available in institutions of higher and further education. Students are told how to use the package before they are introduced to the ideas of methods of data analysis. This clear, jargon-free textbook will be an invaluable aid for students beginning courses in the social sciences and related fields, such as social policy, business studies and health care.
This book provides thorough and comprehensive coverage of most of the new and important quantitative methods of data analysis for graduate students and practitioners. In recent years, data analysis methods have exploded alongside advanced computing power, and it is critical to understand such methods to get the most out of data, and to extract signal from noise. The book excels in explaining difficult concepts through simple explanations and detailed explanatory illustrations. Most unique is the focus on confidence limits for power spectra and their proper interpretation, something rare or completely missing in other books. Likewise, there is a thorough discussion of how to assess uncertainty via use of Expectancy, and the easy to apply and understand Bootstrap method. The book is written so that descriptions of each method are as self-contained as possible. Many examples are presented to clarify interpretations, as are user tips in highlighted boxes.
