Pizza Order in the Semanic Web?!

Untamed fever has been annoying me for nearly 3 weeks. That is too bad! I even could not do any work at all. At this time, I really understand the truth value of health, in particular for a young energic man. I have no any ideas how the virus could visit me and stay here for so long time this time. For the sake of God, it happens during Xmas, this should-be-lovely season:(

I have to choose reading as my normal life because I really feel that is only thing I can do except eating the medicines. Occasionally I picked up this piece from some website (playing with sound please). It gives me a really strong injection at this time. One thing, it is very happy to see this kind of application people could imagine in our future life, which combines many technologies together to deliver the services in such an intelligent fashion. The customers would not only get satisfactory services but also get considerate "unexpected" care. That is so cool! But on the other hand, I doubt how many people are willing to accept this application. It seems to integrate too many sensitive data into the applications. In the other words, too many sensitive data should not be open in such "wildness". The Semantic Web make the existing web to be a hugh data storing base. The applications built upon it could communicate and understand each other with the great assistance of the large amount of available structured data. However, it does not mean that everyone could not easily hold the control of the data without the authorisation, in particualr the sensitive data. Taking this example, I believe that nobody expect that their medical records are unveiled for the public, even used by the third party in their real applications. Sound horrible! Maybe I exaggerate this issue.
