Presenting a reference model architecture for the design of intelligent systems

Engineering of Mind presents the foundations for a computational theory of intelligence. It discusses the main streams of investigation that will eventually converge in a scientific theory of mind and proposes an avenue of research that might best lead to the development of truly intelligent systems.

This book presents a model of the brain as a hierarchy of massive parallel computational modules and data structures interconnected by information pathways. Using this as the basic model on which intelligent systems should be based, the authors propose a reference model architecture that accommodates concepts from artificial intelligence, control theory, image understanding, signal processing, and decision theory. Algorithms, procedures, and data embedded within this architecture would enable the analysis of situations, the formulation of plans, the choice of behaviors, and the computation of uncertainties. The computational power to implement the model can be achieved in practical systems in the foreseeable future through hierarchical and parallel distribution of computational tasks.

The authors’ reference model architecture is expressed in terms of the Real-time Control System (RCS) that has been developed primarily at the National Institute of Standards and Technology. Suitable for engineers, computer scientists, researchers, and students, Engineering of Mind blends current theory and practice to achieve a coherent model for the design of intelligent systems.

Semantic Web services promise to automate tasks such as discovery, mediation, selection, composition, and invocation of services, enabling fully flexible automated e-business. Their usage, however, still requires a significant amount of human intervention due to the lack of support for a machine-processable description. In this book, Jos de Bruijn and his coauthors lay the foundations for understanding the requirements that shape the description of the various aspects related to Semantic Web services, such as the static background knowledge in the form of ontologies, the functional description of the service, and the behavioral description of the service. They introduce the Web Service Modeling Language (WSML), which provides means for describing the functionality and behavior of Web services, as well as the underlying business knowledge, in the form of ontologies, with a conceptual grounding in the Web Service Modeling Ontology. Academic and industrial researchers as well as professionals will find a comprehensive overview of the concepts and challenges in the area of Semantic Web services, the Web Services Modeling Language and its relation to the Web Services Modeling Ontology, and an in-depth treatment of both enabling technologies and theoretical foundations.

According to the W3C Semantic Web Activity [1]: The Semantic Web provides a common framework that allows data to be shared and reused across appli- tion, enterprise, and community boundaries. This statement clearly explains that the Semantic Web is about data sharing. Currently, the Web uses hyperlinks to connect Web pages. The Semantic Web goes beyond that and focuses on data and envisions the creation of the web of data. On the Semantic Web, anyone can say anything about any resource on the Web. This is fully based on the concept of semantic - notations, where each resource on the Web can have an assigned meaning. This is done through the use of ontologies as a formal and explicit representation of domain concepts and their relationships [2]. Ontologies are formally based on description logics. This enables agents and applications to reason over the data when searching the Web, which has not previously been possible. Web 2. 0 has gradually evolved from letting the Web users play a more active role. Unlike the initial version of the Web, where the users mainly "consumed" content, users are now offered easy-to-use services for content production and publication. Mashups, blogs, wikis, feeds, interface remixes, and social networking/tagging s- tems are examples of these well-known services. The success and wide adoption of Web 2. 0 was in its reliance on social interactions as an inevitable characteristic of the use and life of the Web. In particular, Web 2.

Vulnerability management (VM) has been around for millennia. Cities, tribes, nations, and corporations have all employed its principles. The operational and engineering successes of any organization depend on the ability to identify and remediate a vulnerability that a would-be attacker might seek to exploit. What were once small communities became castles. Cities had fortifications and advanced warning systems. All such measures were the result of a group recognizing their vulnerabilities and addressing them in different ways. Today, we identify vulnerabilities in our software systems, infrastructure, and enterprise strategies. Those vulnerabilities are addressed through various and often creative means. Vulnerability Management demonstrates a proactive approach to the discipline. Illustrated with examples drawn from Park Foreman's more than three decades of multinational experience, the book demonstrates how much easier it is to manage potential weaknesses than to clean up after a violation. Covering the diverse realms that CISOs need to know and the specifics applicable to singular areas of departmental responsibility, he provides both the strategic vision and action steps needed to prevent the exploitation of IT security gaps, especially those that are inherent in a larger organization. Completely updated, the second edition provides a fundamental understanding of technology risks-including a new chapter on cloud vulnerabilities and risk management-from an interloper's perspective. This book is a guide for security practitioners, security or network engineers, security officers, and CIOs seeking understanding of VM and its role in the organization. To serve various audiences, it covers significant areas of VM. Chapters on technology provide executives with a high-level perspective of what is involved. Other chapters on process and strategy, although serving the executive well, provide engineers and security managers with perspective on the role of VM technology and processes in the success of the enterprise.

Hypermedia & the Web An Engineering Approach David Lowe, University of Technology, Sydney, Australia Wendy Hall, University of Southampton, UK The rich online world offered through the Web is marred by the chaos which underlies it. At the very early stages of understanding how to harness the power of this new medium, electronic document creators, managers and researchers often spend time on technology innovations at the expense of adopting the sound engineering principles which have paid such dividends in the software industry. Hypermedio & the Web approaches interactive information (concentrating on hypertext documents) as a structure requiring management, quantification and documentation. From analysing the purpose for which a website, CD-ROM or online archive is created, assessing the characteristics and resources needed for the process of building each one, to the assessment of the end product itself, this book attempts to carve out features that are essential to the successful structuring of information in an electronic environment. This is an ambitious book charting an emerging discipline. It is an essential tool to help developers and educators shape and maintain useful and relevant electronic information. 'Hypermedia Engineering hasn't produced many tangible benefits in real-life situations, because very few people practise it. That's why the book is needed.' David Barron, Southampton University 'This book is interesting and excellently fulfills a current need [by] providing an exhaustive and up-to-date vision of the hypermedia field.' Fabio Vitali, University of Bologna 'The strength of this book is its breadth - it covers many of the issues in hypermedia with examples from thetechnical to the managerial. Students could use these as starting points when designing or evaluating hypermedia systems.' David Sharp, Imperial College of Science and Technology 'Information systems developers and managers should find this a helpful guide for developing hypermedia applications.'
