Por que precisamos da Web Semântica? A Web de hoje não é suficiente? Estamos caminhando para uma Web com dados cada vez mais relacionados e abertos. A Web Semântica é uma extensão da nossa web atual, em que nós não vamos apenas ler e produzir conteúdo, mas usar as máquinas para relacionar e reutilizar essas informações da melhor maneira possível. Ela se baseia na ideia de que o conteúdo deve ter uma descrição digital, padronizada por vocabulários, que provê meios para as máquinas entenderem do que aquilo se trata, de modo que os computadores possam interpretar, gerar e distribuir conteúdo útil, de acordo com as necessidades dos usuários. Neste livro, Diego Eis traz uma introdução à Web Semântica, mostrando de onde ela surgiu e apontando nossa trajetória em direção a ela. Sabemos que ela se faz cada vez mais presente no nosso dia a dia, interpretando o conteúdo de nossos e-mails, por exemplo; portanto, é importante aprender seus conceitos e acompanhar a evolução da Web. Você vai descobrir que, apesar de poder ser um assunto altamente técnico, a parte da Web Semântica que mais impacta os desenvolvedores e nosso trabalho diário é muito simples de ser aplicada e implementada.

New technologies will underpin the future generation of library catalogues. To facilitate their role providing information, serving users, and fulfilling their mission as cultural heritage and memory institutions, libraries must take a technological leap; their standards and services must be transformed to those of the Semantic Web. Bibliographic Information Organization in the Semantic Web explores the technologies that may power future library catalogues, and argues the necessity of such a leap. The text introduces international bibliographic standards and models, and fundamental concepts in their representation in the context of the Semantic Web. Subsequent chapters cover bibliographic information organization, linked open data, methodologies for publishing library metadata, discussion of the wider environment (museum, archival and publishing communities) and users, followed by a conclusion. - The product of over thirty years'experience and in-depth understanding of bibliographic metadata - Takes both a bottom up and top down approach: from basic standards and case studies to Semantic Web tools and services; and from abstract models and generic guidelines to applications - Tells an insiders'story of the experience developing tools for the transition of library systems, metadata, and its utility, into the new milieu

It also explores formal semantics, OWL querying, the relationship between rules and OWL, and ontology engineering and applications.

With this book, the promise of the Semantic Web -- in which machines can find, share, and combine data on the Web -- is not just a technical possibility, but a practical reality Programming the Semantic Web demonstrates several ways to implement semantic web applications, using current and emerging standards and technologies. You'll learn how to incorporate existing data sources into semantically aware applications and publish rich semantic data.Each chapter walks you through a single piece of semantic technology and explains how you can use it to solve real problems. Whether you're writing a simple mashup or maintaining a high-performance enterprise solution,Programming the Semantic Web provides a standard, flexible approach for integrating and future-proofing systems and data.This book will help you:Learn how the Semantic Web allows new and unexpected uses of data to emergeUnderstand how semantic technologies promote data portability with a simple, abstract model for knowledge representationBecome familiar with semantic standards, such as the Resource Description Framework (RDF) and the Web Ontology Language (OWL)Make use of semantic programming techniques to both enrich and simplify current web applications

Peer-to-peer systems are evolving with new information-system architectures, leading to the idea that the principles of decentralization and self-organization will offer new approaches in informatics, especially for systems that scale with the number of users or for which central authorities do not prevail. This book describes a new way of building

Initiatives, such as INSPIRE and the US DHS Geospatial Data Model, are working to develop a rich set of standards that will create harmonized models and themes for the spatial information infrastructure. However, this is only the first step. Semantically meaningful models must still be developed in order to stimulate interoperability.Creatin

The promise of the Semantic Web to provide a universal medium to exchange data information and knowledge has been well publicized. There are many sources too for basic information on the extensions to the WWW that permit content to be expressed in natural language yet used by software agents to easily find, share and integrate information. Until now individuals engaged in creating ontologies-- formal descriptions of the concepts, terms, and relationships within a given knowledge domain-- have had no sources beyond the technical standards documents. Semantic Web for the Working Ontologist transforms this information into the practical knowledge that programmers and subject domain experts need. Authors Allemang and Hendler begin with solutions to the basic problems, but don't stop there: they demonstrate how to develop your own solutions to problems of increasing complexity and ensure that your skills will keep pace with the continued evolution of the Semantic Web.• Provides practical information for all programmers and subject matter experts engaged in modeling data to fit the requirements of the Semantic Web.• De-emphasizes algorithms and proofs, focusing instead on real-world problems, creative solutions, and highly illustrative examples. • Presents detailed, ready-to-apply'recipes for use in many specific situations.• Shows how to create new recipes from RDF, RDFS, and OWL constructs.

Semantic Webs promise to revolutionize the way computers find and integrate data over the internet. They will allow Web agents to share and reuse data across applications, enterprises, and community boundaries. However, this improved accessibility poses a greater threat of unauthorized access, which could lead to the malicious corruption of informa

The Semantic Web, extends the popular, day-to-day Web, enabling computers and people to effectively work together by giving information well-defined meaning. Knitting the Semantic Web explains the interdisciplinary efforts underway to build a more library-like Web through “semantic knitting.” The book examines foundation activities and initiatives leading to standardized semantic metadata. These efforts lead to the Semantic Web—a network able to support computational activities and provide people with services efficiently. Leaders in library and information science, computer science, and information intensive domains provide insight and inspiration to give readers a greater understanding of the evolution of the Semantic Web. Librarians and information professionals are uniquely qualified to play a major role in the development and maintenance of the Semantic Web. Knitting the Semantic Web closely examines this crucial relationship in detail. This single source reviews the foundations, standards, and tools underlying the Semantic Web and presents thoughtful perspectives in the context of 2.0 developments. Many chapters include figures to illustrate concepts and ideas, and the entire text is extensively referenced. Topics in Knitting the Semantic Web include: RDF, its expressive power, and its ability to underlie the new Library catalog card for the coming century the value and application for controlled vocabularies SKOS (Simple Knowledge Organization System), the newest Semantic Web language managing scheme versioning in the Semantic Web Physnet portal service for physics Semantic Web technologies in biomedicine developing the United Nations Food and Agriculture ontology Friend Of A Friend (FOAF) vocabulary specification—with a real world case study at a university Web/Library 2.0 and more Knitting the Semantic Web is a stimulating resource for professionals, researchers, educators, and students in library and information science, computer science, information architecture, Web design, and Web services.

Even though the semantic Web is a relatively new and dynamic area of research, a whole suite of components, standards, and tools have already been developed around it. Using a concrete approach, Introduction to the Semantic Web and Semantic Web Services builds a firm foundation in the concept of the semantic Web, its principal technologies, its rea

These are exciting times in the fields of Fuzzy Logic and the Semantic Web, and this book will add to the excitement, as it is the first volume to focus on the growing connections between these two fields. This book is expected to be a valuable aid to anyone considering the application of Fuzzy Logic to the Semantic Web, because it contains a number of detailed accounts of these combined fields, written by leading authors in several countries. The Fuzzy Logic field has been maturing for forty years. These years have witnessed a tremendous growth in the number and variety of applications, with a real-world impact across a wide variety of domains with humanlike behavior and reasoning. And we believe that in the coming years, the Semantic Web will be major field of applications of Fuzzy Logic. This book, the first in the new series Capturing Intelligence, shows the positive role Fuzzy Logic, and more generally Soft Computing, can play in the development of the Semantic Web, filling a gap and facing a new challenge. It covers concepts, tools, techniques and applications exhibiting the usefulness, and the necessity, for using Fuzzy Logic in the Semantic Web. It finally opens the road to new systems with a high Web IQ. Most of today's Web content is suitable for human consumption. The Semantic Web is presented as an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation. For example, within the Semantic Web, computers will understand the meaning of semantic data on a web page by following links to specified ontologies. But while the Semantic Web vision and research attracts attention, as long as it will be used two-valued-based logical methods no progress will be expected in handling ill-structured, uncertain or imprecise information encountered in real world knowledge. Fuzzy Logic and associated concepts and techniques (more generally, Soft Computing), has certainly a positive role to play in the development of the Semantic Web. Fuzzy Logic will not supposed to be the basis for the Semantic Web but its related concepts and techniques will certainly reinforce the systems classically developed within W3C. In fact, Fuzzy Logic cannot be ignored in order to bridge the gap between human-understandable soft logic and machine-readable hard logic. None of the usual logical requirements can be guaranteed: there is no centrally defined format for data, no guarantee of truth for assertions made, no guarantee of consistency. To support these arguments, this book shows how components of the Semantic Web (like XML, RDF, Description Logics, Conceptual Graphs, Ontologies) can be covered, with in each case a Fuzzy Logic focus. - First volume to focus on the growing connections between Fuzzy Logic and the Semantic Web - Keynote chapter by Lotfi Zadeh - The Semantic Web is presently expected to be a major field of applications of Fuzzy Logic - It fills a gap and faces a new challenge in the development of the Semantic Web - It opens the road to new systems with a high Web IQ - Contributed chapters by Fuzzy Logic leading experts

As the World Wide Web continues to expand, it becomes increasingly difficult for users to obtain information efficiently. Because most search engines read format languages such as HTML or SGML, search results reflect formatting tags more than actual page content, which is expressed in natural language. Spinning the Semantic Web describes an exciting new type of hierarchy and standardization that will replace the current'web of links'with a'web of meaning.'Using a flexible set of languages and tools, the Semantic Web will make all available information -- display elements, metadata, services, images, and especially content -- accessible. The result will be an immense repository of information accessible for a wide range of new applications.This first handbook for the Semantic Web covers, among other topics, software agents that can negotiate and collect information, markup languages that can tag many more types of information in a document, and knowledge systems that enable machines to read Web pages and determine their reliability. The truly interdisciplinary Semantic Web combines aspects of artificial intelligence, markup languages, natural language processing, information retrieval, knowledge representation, intelligent agents, and databases.

Developing Semantic Web Services is well-informed about work on WS [Web Services] and the SemWeb [Semantic Web], and in particular... understand[s] OWL-S... very well.... Also, the book... fill[s] a need that, to my knowledge, hasn't been met at all. ---David Martin, editor OWL-S Coalition The inventor of the World Wide Web, Tim Berners-Lee, is also the originator of the next generation Web architecture, the Semantic Web. Currently, his World Wide Web consortium (W3C) team works to develop, extend, and standardize the Web's markup languages and tools. The objective of the Semantic Web Architecture is to provide a knowledge representation of linked data in order to allow machine processing on a global scale. The W3C has developed a new generation of open standard markup languages which are now poised to unleash the power, flexibility, and above all---logic---of the next generation Web, as well as open the door to the next generation of Web Services. There are many ways in which the two areas of Web Services and the Semantic Web could interact to lead to the further development of Semantic Web Services. Berners-Lee has suggested that both of these technologies would benefit from integration that would combine the Semantic Web's meaningful content with Web Services'business logic. Areas such as UDDI and WSDL are ideally suited to be implemented using Semantic Web technology. In addition, SOAP could use RDF payloads, remote RDF query and updates, and interact with Semantic Web business rules engines, thereby laying the foundation for Semantic Web Services. This book presents the complete Language Pyramid of Web markup languages, including Resource Description Framework (RDF), Web Ontology Language (OWL) and OWL-Services (OWL-S) along with examples and software demos. The source code for the Semantic Web Author, an Integrated Development Environment for Semantic Markup Languages is available on CD-ROM with the book.
