Semantic Web Services: Concepts, Technologies, and Applications ReviewSome books have come out on Service Oriented Architecture, like SOA Principles of Service Design (The Prentice Hall Service-Oriented Computing Series from Thomas Erl). But while seemingly comprehensive, they only scrape the start of the problem. Much remains to be done, when applying to real world data sets. This book by Studer et al can be considered a next step in SOA.
It points out huge problems that still remain. Earlier books on SOA and Web Services tend to focus on the syntactical issues. Which is the first and simplest step. But given a schema written by one party, there is typically a need for manual impedance matching with another schema on the same topic. Issues arise due to the writing, understanding and maintenance of ontologies.
The book shows what the human in the loop has to do. Along with extended examples of actual realistic problems, taken from German government data.Semantic Web Services: Concepts, Technologies, and Applications OverviewIn this volume, Rudi Studer and his team deliver a self-contained compendium about the exciting field of Semantic Web services, starting with the basic standards and technologies and also including advanced applications in eGovernment and eHealth. The contributions provide both the theoretical background and the practical knowledge necessary to understand the essential ideas and to design new cutting-edge applications.

Scripting Intelligence: Web 3.0 Information Gathering and Processing (Expert's Voice in Open Source) ReviewThis four-part book is focused on programming techniques and technologies that in the author's opinion can help next generation web applications handle data more "intelligently". The code samples are implemented in Ruby (and a little bit of Java).
Part One (Chapters 1-3) is basically an introduction to text and natural language processing, sampling tools and techniques for extracting raw text from various document types (e.g., pdf to plain text), classifying a document's subject matter (e.g., is this a document on "Health" or "Politics") or overall sentiment direction (degree of positiveness or negativeness), and recognizing entities such as persons and places in text (e.g., is "Florida" in a given sentence referring to a U.S. state, which is a place entity, or a person whose last name is Florida?).
Part Two (Chapters 4-7) provides tutorials on the Semantic Web, explaining what the RDF subject-predicate-object data format is and how a query language like SPARQL supports inferencing. URLs for publicly available RDF data sets, as well as tools and services useful for exploring them are given.
Part Three (Chapters 8-12) covers topics relating to the use of object-relational mapping (e.g., ActiveRecord and DataMapper used in standalone mode) and search (e.g., Lucene and Sphinx) technologies, publishing relational data as RDF data,and strategies for large-scale data storage involving the use of multiple servers, memcached, CouchDB, Amazon S3, or Amazon EC2.
Part Four (Chapters 13-15) includes a really good tutorial on the use of Hadoop-like Map Reduce facilities for large scale data processing, and ties things together by showing how the knowledge learned from previous chapters can be applied to the development of more substantial web applications.
The author uses many open-source gems (Ruby-centric software library) and tools in this book (most will work fine on Linux, Mac, or Windows, and with Ruby 1.8.x or 1.9, but exceptions are reported clearly), so in many cases, you only need to write a limited amount of code to follow along. If you don't want to download and install the gems, Appendix A provides instructions on how to apply for an Amazon Web Services account to access a ready to use Amazon Machine Image put together by the author for use on a rented Amazon EC2 Server Instance.
Because of the breadth of coverage, each technology can only be discussed to a limited depth, which some readers may find adequate and some may not, depending on a reader's interest on a particular topic, but most should still find this book to be a valuable resource, and that the author explains things well and concisely.Scripting Intelligence: Web 3.0 Information Gathering and Processing (Expert's Voice in Open Source) OverviewIntelligent information management is the key to many Web 2.0 applications, and Semantic Web technologies like the SPARQL query language are helping Web 2.0 evolve into Web 3.0. This book addresses how to use Ruby not only for basic information management tasks, but also how to use it with Semantic Web tools like RDF Schema and SPARQL. This book offers practical advice and example code rather than getting bogged down in the academic and theoretical side of information management.This book offers the reader recipes using Ruby for intelligent information management including information extraction from text, using Semantic Web technologies, information gathering (relational database metadata, web scraping, Wikipedia, Freebase), combining information from multiple sources, and strategies for publishing processed information. This book will be a valuable tool for anyone needing to gather, process, and publish web or database information.

A Developer's Guide to the Semantic Web ReviewNot only does A Developer's Guide to Semantic Web offer an excellent introduction to "what is" Semantic Web, but it also guides the readers onto the "how to" stage with assiduously, almost mind-numbingly easy to understand, step by step coding examples. Needless to say, the author has an amazing grasp of the Semantic web technology himself. Unlike some quite complicated and mind-boggling books on Semantic Web, A Developer's Guide to Semantic Web is easy to comprehend, therefore an outstanding tool. Concepts such as RDF, OWL, SPARQL, and well-known applications such as FOAF, Wiki, DBpedi and LOD are brilliantly illustrated with ample coding examples. The last section of the book weaves all of them together with raw examples of running applications, which are readily available for use. This is a must-read for students, researchers, software engineers and developers who are interested in the Semantic Web technology. Highly recommended.A Developer's Guide to the Semantic Web OverviewCovering the theory, technical components and applications of the Semantic Web, this book's unrivalled coverage includes the latest on W3C standards such as OWL 2, and discusses new projects such as DBpedia. It also shows how to put theory into practice.

Semantic Web For Dummies ReviewThe Semantic Web is the logical next step in the evolution of the ENTIRE Web, and this book makes a strong case why its not all hype and a pipe-dream as some detractors would put it.
And Jeff Pollock knows what he's talking about. A well-known figure in Semantic Web circles, he also manages Fusion - Oracle's middleware solution for the enterprise.
In it, he clearly explains what's wrong with the current state of the Web, and how we manage and produce data in general. He shows how Semantic technologies can clear the way for computers and systems not only in helping us produce (and drown ourselves) in a sea of data, but actually help us consume and find information in it.
Despite the "for Dummies" pejorative, the text is actually quite useful even for veteran Semantic Web followers. It gives a grand (though necessarily abbreviated) tour of all the foundation standards and technologies in the context of their applications in everyday life and behind the corporate firewall.
For a corporate practitioner like myself that has long struggled with abstract, academic examples, the book is a long-awaited addition that will help me evangelize the promise of "the grand database in the sky".Semantic Web For Dummies OverviewSemantic Web technology is already changing how we interact with data on the Web. By connecting random information on the Internet in new ways, Web 3.0, as it is sometimes called, represents an exciting online evolution.
Whether you're a consumer doing research online, a business owner who wants to offer your customers the most useful Web site, or an IT manager eager to understand Semantic Web solutions, Semantic Web For Dummies is the place to start! It will help you:
Know how the typical Internet user will recognize the effects of the Semantic Web
