The aim of an IR system is to estimate the relevance of documents to users' information needs expressed by means of a query. This difficult and complex task is pervaded with imprecision and uncertainty. The application of soft computing techniques helps in obtaining greater flexibility.
This phenomenological investigation of lived experience suggests that human understanding inevitably relies on objectivist comprehensions due to ethical imperatives that are necessitated by communal existence.
A collection of papers presented at the 2nd International Conference on Informatics in Control, Automation and Robotics (ICINCO). This book is aimed at professionals working on the control and robotics area, especially those who need to maintain knowledge about trends in development methods and applications.
Provides an exposition of the implications and interpretations of the fundamentals of discrete information theory and coding. Focusing on the results of practical applications, this text covers information measures, Shannon's channel capacity/coding theorems, and source and channel coding concepts.
This book is a history of the future. It shows how our contemporary understanding of the Net is shaped by visions of the future that were put together in the 1950s and 1960s.
'This book would make a strong addition to a graduate-level course on health communication. With complementary reading to broaden students' knowledge of the core theories and empirical research applied to message design, this book would enhance students' capacity to link health communication theory and practice' Health Policy and Planning
Provides an introduction to information and coding theory. This title focuses on information theory, covering uniquely decodable and instantaneous codes, Huffman coding, entropy, information channels, and Shannon's Fundamental Theorem.
There are two basic methods of error control for communication, both involving coding of the messages. This book begins with a short introduction to the theory of block codes with emphasis on the parts important for error detection. It offers an account of the known results on the probability of undetected error on the q-ary symmetric channel.
Information technology spending in the US over the last decade is estimated at 3 trillion dollars, yet, by many accounts, has not worked. In this text, the author proposes a way of looking at information management which takes into account the total information environment within an organization.
Constitutes the refereed proceedings of the IFIP TC 8 Information Systems Stream that was held in Milan, Italy on September 7-10, 2008.
Social scientists often dismiss the media as untrustworthy and irresponsible and the media frequently regard social scientists as incapable of giving a straight answer. This work examines these issues from the viewpoint of the media and social scientists who have had extensive media contact.
Drawing on case studies from Denmark, The Netherlands and the UK, this book discusses new information and communication technologies. It explores their role in the restructuring of Western democratic political systems.
The latest edition of this classic is updated with new problem sets and material The Second Edition of this fundamental textbook maintains the book's tradition of clear, thought-provoking instruction. Readers are provided once again with an instructive mix of mathematics, physics, statistics, and information theory.
What have the invention of the wheel, Pompeii, the Wall Street Crash, Harry Potter and the internet got in common? Why are all forecasters con-artists? And, what can Catherine the Great's lovers tell us about probability? This book shows us how to stop trying to predict everything and take advantage of uncertainty.
