Abstract

This timely introduction to spectral feature selection illustrates the potential of this powerful dimensionality reduction technique in high-dimensional data processing. It presents the theoretical foundations of spectral feature selection, its connections to other algorithms, and its use in handling both large-scale data sets and small sample problems. Readers learn how to use spectral feature selection to solve challenging problems in real-life applications and discover how general feature selection and extraction are connected to spectral feature selection. Source code for the algorithms is available online.

Abstract

This book introduces a new mechanism for representing social networks in which pairwise relationships can be drawn from a range of realistic possibilities, including different types of relationships, different strengths in the directions of a pair, positive and negative relationships, and relationships whose intensities change with time. For each possibility, the book shows how to model the social network using spectral embedding. It also shows how to compose the techniques so that multiple edge semantics can be modeled together. The modeling techniques are then applied to a range of datasets to show how they can produce results that are useful in understanding real-world social networks.

Abstract

Drawing on the authors’ more than six years of R&D in location-based information systems as well as their participation in defining the Java ME Location API 2.0, this text describes the technical components needed to create location-based services with an emphasis on nonproprietary, freely available solutions that work across different technologies and platforms. Each chapter presents a general real-time tracking system example that can be easily adapted to target any application domain and that can incorporate other sensor data to make the system "participatory sensing" or "human-centric sensing." A companion website offers many supporting materials.

Abstract

This book is the first to combine coverage of fuzzy logic and Semantic Web languages. It provides in-depth insight into fuzzy Semantic Web languages for non-fuzzy set theory and fuzzy logic experts. It also helps researchers of non-Semantic Web languages get a better understanding of the theoretical fundamentals of Semantic Web languages. The first part of the book covers all the theoretical and logical aspects of classical (two-valued) Semantic Web languages. The second part explains how to generalize these languages to cope with fuzzy set theory and fuzzy logic.

Abstract

This is the first full-length study of digital identity in a transactional context, from a legal perspective. Clare Sullivan's analysis reveals the emergence of a distinct, new legal concept of identity. This concept is particularly clear under a national identity scheme such as the United Kingdom and Indian schemes. However, its emergence is evident even in jurisdictions, like Australia, which do not have a formal national identity scheme. Much of the analysis can also be extrapolated to proprietary schemes such as those run by banks and other businesses.&#xD;&#xD;An individual’s digital identity which is used for transactional purposes has crucial functions which give it legal personality. The author argues that an individual’s digital identity also has the characteristics of property which can, and should, be legally protected. Identity theft is defined using the emergent concept and the study shows that digital identity is property which capable of actually being stolen and criminally damaged.&#xD;&#xD;The study examines the emergence of attendant legal rights and duties including a new right to digital identity and its legal protection. Dr Sullivan argues that an individual has the right to an accurate, functional digital identity and shows that this right exists in addition to the right to privacy.&#xD;&#xD;Dr Sullivan maintains that, considering the essentially public nature of identity, the right to identity provides better, and more appropriate, protection than is afforded by the right to privacy. She asserts that the importance of the right to identity in this context has been obscured by the focus on privacy in international legal scholarship and jurisprudence.&#xD;&#xD;The functions and legal nature of digital identity are analysed using real examples which highlight the implications for individuals, businesses and government. The findings have the potential to fundamentally change the way digital identity is legally and commercially regarded.

Abstract

The management of time and events is central to various domains of informatics, from embedded circuits and software programs in all sorts of objects to musical creation, or the simulation of physical phenomena. Yet this subject receives little attention in classical informatics. This lecture presents different types of time and event modelling associated with new programming languages. It discusses the notions of density of the moment and of hierarchical and multiform times created by the rep...

Abstract

The book is addressed to young people interested in computer technologies and computer science. The objective of this book is to provide the reader with all the necessary elements to get him or her started in the modern field of informatics and to allow him or her to become aware of the relationship between key areas of computer science. The book is addressed not only to future software developers, but also to all who are interested in computing in a widely understood sense. The authors also expect that some computer professionals will want to review this book to lift themselves above the daily grind and to embrace the excellence of the whole field of computer science. Unlike existing books, this one bypasses issues concerning the construction of computers and focuses only on information processing. Recognizing the importance of the human factor in information processing, the authors intend to present the theoretical foundations of computer science, software development rules, and some business aspects of informatics in non-technocratic, humanistic terms.
