  • As semantic technologies prove their value with targeted applications, there are increasing opportunities to consider their application in social contexts for knowledge, learning, and human development. Semantic Web and Knowledge Management has been accepted as a critical enabler aiming to in crease knowledge-related performance by better use of intellectual assets, in addition to which many governments are forced to increasingly deal with knowledge services that form larger parts of the global economy and society.

  • Smart homes are intelligent environments that interact dynamically and respond readily in an adaptive manner to the needs of the occupants and changes in the ambient conditions. The realization of systems that support the smart homes concept requires integration of technologies from different fields. Among the challenges that the designers face is to make all the components of the system interact in a seamless, reliable and secure manner.

  • Although most of this book can be seen as an attempt to navigate through a landscape of potential and opportunity for a future World Wide Web, it is prudent, as in any navigational exercise, to start by determining one’s present location. To this end, the first chapter is a descriptive walkabout in the current technology of the Web – its concepts and protocols. It sets out first principles relevant to the following exploration, and it explains the terms encountered.

  • Current Semantic Role Labeling technologies are based on inductive algorithms trained over large scale repositories of annotated examples. Frame-based systems currently make use of the FrameNet database but fail to show suitable generalization capabilities in out-of-domain scenarios. In this paper, a state-of-art system for frame-based SRL is extended through the encapsulation of a distributional model of semantic similarity. The resulting argument classification model promotes a simpler feature space that limits the potential overfitting effects....

  • We present a novel fine-grained semantic representation of text and an approach to constructing it. This representation is largely extractable by today’s technologies and facilitates more detailed semantic analysis. We discuss the requirements driving the representation, suggest how it might be of value in the automated tutoring domain, and provide evidence of its validity.

  • Modeling multi-level complex systems is the object of this book. Complex systems are assemblies of several subsystems and are characterized by emergent behavior resulting by nonlinear interactions among subsystems for multiple levels of organization. The complexity of numerous systems is rooted in the existence of many levels of self-organization corresponding to different time and space scales. There is a need to provide general frameworks able to combine several scales and reality levels of the complex systems in one coherent and transdisciplinary discourse.

  • Most books that use MATLAB are aimed at readers who know how to program. This book is for people who have never programmed before. As a result, the order of presentation is unusual. The book starts with scalar values and works up to vectors and matrices very gradually. This approach is good for beginning programmers, because it is hard to understand composite objects until you understand basic programming semantics.

  • News flash: the web is kind of a Big Deal. It is difficult to consider its full impact on technology, society, commerce, education, governance, and entertainment without resorting to grand language that has been stated many times before. It is a Big Deal and we will never be the same because of it. But, here’s the thing. If we sat down and tried to rebuild the web today, knowing what we know from 20 years of experience with it, we would probably fail. The problem is that as software developers, we generally think in terms of software constructs: objects, services, methods, etc.

  • Descriptive mark-up consists of codes that describe the logical structure and semantics of a document, usually in a way which can be interpreted by many different software applications. The two main open standards for descriptive mark-up are SGML (Standard Generalized Markup Language), published as a Standard by the International Standards Organization (ISO) in 1986, and XML (Extensible Markup Language), which was published as a Recommendation of the World Wide Web Consortium (W3C) in 1998.

  • The gSOAP tools provide a SOAP/XML-to-C/C++ language binding to ease the development of SOAP/XML Web services and client application in C and C++. Most toolkits for C++ Web services adopt a SOAP-centric view and offer APIs that require the use of class libraries for SOAP- specific data structures. This often forces a user to adapt the application logic to these libraries. In contrast, gSOAP provides a C/C++ transparent SOAP API through the use of compiler technology that hides irrelevant SOAP-specific details from the user.
