This is the second article in our series that expands the code example from Chapter 5 of Semantic Web Programming to cover the semantics of OWL 2. This article covers property chains. The code can be downloaded from here (zip, 7z, tar.gz) and includes an Eclipse project with all required dependencies.
This article focuses on the semantics of property chains and how they are interpreted and applied in a reasoner that supports most of OWL 2 semantics (Pellet 2.0 RC6 – see the Pellet documentation for a full list of the semantics supported in each release candidate).
As I said in the first article, for a more in-depth exploration of OWL and Semantic Web, feel free to reference the book as needed or buy a copy so you can learn about the cool stuff in this article and more. Click the link below to read the rest of the article…

This article is the first in a short series of articles that expands the code example from Chapter 5 of Semantic Web Programming to include some of the features of OWL 2. The code can be downloaded from here (zip, 7z, tar.gz), including an Eclipse project and all dependencies. This article focuses on how the semantics of qualified cardinality restrictions are interpreted and applied in a reasoner that supports most of OWL 2 semantics (Pellet 2.0 RC6 – see the Pellet documentation for a full list of the semantics supported in each release candidate).

Recall from Chapter 4 in the book that cardinality restrictions are a way to specify the number of statements that describe an individual with a unique value that have a particular property as the predicate of each statement… Read more…

The authors will be presenting a tutorial and overview of future issues on the Semantic Web at the Semantic Technology Conference in San Jose, California June 14-18.
This tutorial outlines a step-by-step, code-based approach to enable you to quickly master the fundamentals in building a semantic Web application. We quickly establish the key concepts and their relationship to application development. Then we programmaticly build the knowledge model, integrate diverse information sources, expose to various reasoners, query the unified value, and then export to various formats and methods using an iterative, collaborative format to get you involved and learning. This takes you through all necessary tools and techniques to quickly get started on your own solution.

The authors will be presenting a tutorial on the Semantic Web at the 2009 JavaOne Conference June 2-5. The tutorial will be based on the content of the book and outlines a step-by-step, Java-based approach to enable participants to quickly master the fundamentals of building a Semantic Web application using Java.
More information can be found here. We hope to see some of you there!
