More Information About This Book
- Perhaps the only one with a very concrete, introductory practical approach of showing the reader how to do things in the Semantic Web - commented by one of the reviewers;
- over 150 copies sold for the first month - THANK YOU!
- 3 universities have adopted the book as their course textbook: Department of Computer Science, University of Hong Kong, Department of Computer Engineering, Eastern Mediterranean University, Department of Computer Science Engineering, SRM University.
- How do you like this book? Have questions about the book? let me hear from you!
About Semantic Web
- It all starts here: The Semantic Web (Scientific American, May 2001), where the vision of semantic Web is formally described by Berners-Lee.
- RDF as the fundamental builidng block of semantic Web, and
- RDFS offers a vocabulary and common language that RDF statements can use to express facts, further more,
- OWL as a Web Ontology language, provides much better expression power than RDFS, and certainly,
- you need to be familiar with XML in order to understand the above semantic Web components. And finally,
- you can read W3C's document to get an overall understanding about semantic Web.
- my book helps you to overcome this steep learning curve, it makes learning and understanding of the semantic Web much easier, many real life examples and coding examples are also included in the book.
- There are tools available to help you code on Semantic Web. is my favorite - learn it, use it and love it!
My Other Writings
- some of my other writings are published in .
- here is a collection of these articles.
- one popular article: Single Server With Multiple Clients : a Simple C++ Implementation, and you might want to read this one first: A light-weighted client/server socket class in C++.
My Current Interest: Web Agent
- here is a good site about Web agent: .
- not all search engines are created equal, but there is a crawler behind each and every search engine. A crawler is in fact a Web agent. How to build your own search engine? Read this article of mine, you will konw the answer, and you will also have a taste of crawler as Web agent. Notice although the main code is in the article, I did not include everything you need to make it work. contact me if you need the rest of the code.
- several books about Web agent: [1] Programming Bots, Spiders, and Intelligent Agents in Microsoft Visual C++. [2] Mobile Agents. [3] Constructing Intelligent Agents Using Java: Professional Developer's Guide.

My Favorite Sports: !
- here is a list of events of this year.
- is a good site you can use to learn basic tennis skills.
- Currently, I am playing at on level 3.5-, it is indeed a great experience. Check it out!

My Favorite Recreations
- yes,it is photography!!
- a great book about photograph: The Basic Book Of Photography.
- and this one has changed my way of taking pictures: Understanding Exposure.
- and since you have gone this far to have finished the above two books, you might as well check this one out: The Ultimate Field Guide to Landscape Photography.
- I am using a Nikon D70, and I still think is the best.
- one important lesson about photograph I have learned: spend your money on lens, not on the body!
- My favorite lenses: (Nikon 50mm f/1.4G), (Nikon 50mm f/1.8D AF), (Nikon 10-24mm f/3.5-4.5G ED AF-S).
Our Ideas, Our Thoughts, and the Life We Share
- is a beautiful logo designed for Beijing 2008 Olympic Game, but it was not really used.
- want to find your home on earth? go here, and you can even locate a bicycle on the street that you are so familiar with. Try it, you will be amazed.
- want to go somewhere? before you do, go , it does not have all the cities yet, but it is definitely fun to visit.
- talking about cool search? check this one out, it feels like you are using a iPhone.
- is an interesting example of Semantic Web application - join the community! As has said, I express my network in a FOAF file, and that is a start of the revolution. And, certainly, you can find my foaf file here.
Miscellaneous Stuff
- is a great place to build your professional network, even to meet your old friends!
- want to have a second life so you can do stuff as you wish? try it out (could be fun)!
