Available in PDF, EPUB and Kindle. Book excerpt: This book explores the relations between objective, media-related, and social attitudinal as well as behavioral realities of private, expert, and corporate agents in the traditions of mass communication, journalism studies and behavioral economics. Results based on time series analyses for German data show that the news reports in a volatile manner on the economy and may influence its development through third-person effects.

Download or read book Affective Computing and Sentiment Analysis written by Khurshid Ahmad and published by Springer Science & Business Media. This book was released on 2011-08-24 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume maps the watershed areas between two 'holy grails' of computer science: the identification and interpretation of affect – including sentiment and mood. The expression of sentiment and mood involves the use of metaphors, especially in emotive situations. Affect computing is rooted in hermeneutics, philosophy, political science and sociology, and is now a key area of research in computer science. The 24/7 news sites and blogs facilitate the expression and shaping of opinion locally and globally. Sentiment analysis, based on text and data mining, is being used in the looking at news and blogs for purposes as diverse as: brand management, film reviews, financial market analysis and prediction, homeland security. There are systems that learn how sentiments are articulated. This work draws on, and informs, research in fields as varied as artificial intelligence, especially reasoning and machine learning, corpus-based information extraction, linguistics, and psychology.

This book was released on 2021-11-26 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital technology covers digital information in every form. The world lives in an information age in which massive amounts of data are being produced to improve our daily lives. This intelligent digital network incorporates interconnected people, robots, gadgets, content, and services all determined by digital transformation. The role of digital technologies in children’s, adolescent’s, and young adult’s lives is significantly increasing across the world. New and emerging devices and services promise to make their lives easier as they create new ways of connecting, creating, and relaxing. They also promise to support learning at home and school by enabling ready access to information and new and exciting pathways for young people to follow their interests. Yet, alongside these conveniences come trade-offs with implications for privacy, safety, health, and well-being. Impact and Role of Digital Technologies in Adolescent Lives provides a deeper understanding of how digital technologies impact the lives of children, adolescents, and young adults; this includes the navigation of developmental tasks and the issues faced when utilizing these technologies. Covering topics such as adolescent stress, cyberbullying, intellectual disabilities, mental health, obesity, social media, and mindfulness practices, this text is essential for sociologists, psychologists, media analysts, technologists, academicians, researchers, students, non-government and government organizations, and professors.
Download or read book Media Sentiment and International Asset Prices written by Samuel P. Fraiberger and published by International Monetary Fund. This book was released on 2018-12-10 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: We assess the impact of media sentiment on international equity prices using more than 4.5 million Reuters articles published across the globe between 1991 and 2015. News sentiment robustly predicts daily returns in both advanced and emerging markets, even after controlling for known determinants of stock prices. But not all news-sentiment is alike. A local (country-specific) increase in news optimism (pessimism) predicts a small and transitory increase (decrease) in local returns. By contrast, changes in global news sentiment have a larger impact on equity returns around the world, which does not reverse in the short run. We also find evidence that news sentiment affects mainly foreign – rather than local – investors: although local news optimism attracts international equity flows for a few days, global news optimism generates a permanent foreign equity inflow. Our results confirm the value of media content in capturing investor sentiment.
