Available in PDF, EPUB and Kindle. Book excerpt: Quite soon, the world’s information infrastructure is going to reach a level of scale and complexity that will force scientists and engineers to approach it in an entirely new way. The familiar notions of command and control are being thwarted by realities of a faster, denser world of communication where choice, variety, and indeterminism rule. The myth of the machine that does exactly what we tell it has come to an end. What makes us think we can rely on all this technology? What keeps it together today, and how might it work tomorrow? Will we know how to build the next generation—or will we be lulled into a stupor of dependence brought about by its conveniences? In this book, Mark Burgess focuses on the impact of computers and information on our modern infrastructure by taking you from the roots of science to the principles behind system operation and design. To shape the future of technology, we need to understand how it works—or else what we don’t understand will end up shaping us. This book explores this subject in three parts: Part I, Stability: describes the fundamentals of predictability, and why we have to give up the idea of control in its classical meaning Part II, Certainty: describes the science of what we can know, when we don’t control everything, and how we make the best of life with only imperfect information Part III, Promises: explains how the concepts of stability and certainty may be combined to approach information infrastructure as a new kind of virtual material, restoring a continuity to human-computer systems so that society can rely on them.

Download or read book In Search of Information Use of Google Trends Data to Narrow Information Gaps for Low income Developing Countries written by Mr.Futoshi Narita and published by International Monetary Fund. This book was released on 2018-12-14 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timely data availability is a long-standing challenge in policy-making and analysis for low-income developing countries. This paper explores the use of Google Trends’ data to narrow such information gaps and finds that online search frequencies about a country significantly correlate with macroeconomic variables (e.g., real GDP, inflation, capital flows), conditional on other covariates. The correlation with real GDP is stronger than that of nighttime lights, whereas the opposite is found for emerging market economies. The search frequencies also improve out-of-sample forecasting performance albeit slightly, demonstrating their potential to facilitate timely assessments of economic conditions in low-income developing countries.
Download or read book Query Understanding for Search Engines written by Yi Chang and published by Springer Nature. This book was released on 2020-12-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a systematic study of practices and theories for query understanding of search engines. These studies can be categorized into three major classes. The first class is to figure out what the searcher wants by extracting semantic meaning from the searcher’s keywords, such as query classification, query tagging, and query intent understanding. The second class is to analyze search queries and then translate them into an enhanced query that can produce better search results, such as query spelling correction or query rewriting. The third class is to assist users in refining or suggesting queries in order to reduce users’ search effort and satisfy their information needs, such as query auto-completion and query suggestion. Query understanding is a fundamental part of search engines. It is responsible to precisely infer the intent of the query formulated by the search user, to correct spelling errors in his/her query, to reformulate the query to capture its intent more accurately, and to guide the user in formulating a query with precise intent. The book will be invaluable to researchers and graduate students in computer or information science and specializing in information retrieval or web-based systems, as well as to researchers and programmers working on the development or improvement of products related to search engines.

Download or read book Navigating Fake News Alternative Facts and Misinformation in a Post Truth World written by Dalkir, Kimiz and published by IGI Global. This book was released on 2020-02-28 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current day and age, objective facts have less influence on opinions and decisions than personal emotions and beliefs. Many individuals rely on their social networks to gather information thanks to social media’s ability to share information rapidly and over a much greater geographic range. However, this creates an overall false balance as people tend to seek out information that is compatible with their existing views and values. They deliberately seek out “facts” and data that specifically support their conclusions and classify any information that contradicts their beliefs as “false news.” Navigating Fake News, Alternative Facts, and Misinformation in a Post-Truth World is a collection of innovative research on human and automated methods to deter the spread of misinformation online, such as legal or policy changes, information literacy workshops, and algorithms that can detect fake news dissemination patterns in social media. While highlighting topics including source credibility, share culture, and media literacy, this book is ideally designed for social media managers, technology and software developers, IT specialists, educators, columnists, writers, editors, journalists, broadcasters, newscasters, researchers, policymakers, and students.

Download or read book Donor Conception and the Search for Information written by Sonia Allan and published by Routledge. This book was released on 2016-10-14 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines donor conception and the search for information by donor-conceived people. It details differing regulatory approaches across the globe, including those that provide for ‘open-identity’ or anonymous donation, or that take a ‘dual-track’ approach. In doing so, it identifies models regarding the recording and release of information about donors that may assist in the further development of the law, policy and associated practices. Arguments for and against donor anonymity are considered, and specifically critiqued. The study highlights contrasting reasoning and emphasis upon various interests and factors that may underpin secrecy, anonymity or openness. The book will be of value to academics, students and legal practitioners involved with this area. It is also relevant to policy makers, health practitioners and anyone with an interest in the subject.

Available in PDF, EPUB and Kindle. Book excerpt: 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 focuses on core concepts, and current trends in the field. This book 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.
