语义Web的思想可以说是把知识表示搬到Web上来，即webize KR; 但事实上，传统的KR被证明是失败的，即AI bubble failure，这样的话，有什么理由去让我们相信语义Web就一定能成功呢？KR披上Web的外衣就能让工业界接收吗？
Tim berners Lee 在他的design note里论述了他的理由：
1.A Semantic Web is not Artificial Intelligence
2.A semantic Web will not require every application to use expressions of arbitrary complexity
3. A semantic Web will not require proof generation to be useful: proof validation will be enough.
4. Knowledge Representation goes Global:
We remove the centralized concepts of absolute truth, total knowledge, and total provability, and see what we can do with limited knowledge
但是，一直觉得他的认证并不充分，也一直没花时间去好好想这个问题。只能
说：相信W3C，相信Sir Tim Berners-Lee 吧。希望听听大家的想法。

Dear Prof. Song,
I would like to hear some comments from you on prospective key research issues in the semantic web (SW) field, and what you are going to choose to focus on? ;)

基本上赞同楼主的观点. 我们在以前的帖子中也讨论了类似的问题:
sementic web的意义何在? http://bbs.xml.org.cn/dispbbs.asp?boardID=2&ID=759

Here is some of my comprehension of the SW. From an application developer point of view, SW is not a big deal. It helps to solve some problem on describing things but mostly for interoperability sake. As we all face a step to describe data in any of our program, to be able to make it *universally* understandable, we tag it (which is the XML fashion). A more general case is to make a tag with another "tag" - namespace where one can refer to as a description of the tag. And if the namespace links to a URL document, it may be further described with ontology basis. So it ends up with that we are sharing model (probably partial) with others.
.....

Thanks and just come to have a discussion here

I think it is a practical view of technology - just to see what will happen given technologies they defined, so there may be killer applications which will be accepted by users, however, we have to see whether it is because of the use of SW technology, like IM and VoIP etc, they do not use SW at all, however, SW may give some extra advantage while may not either.
So I think it is a good time for application developers, just make SW a plugable tech which can be used to extend the possibility of their applications, but not the key. So SW can be treated as a reasoning blackbox which can be replaced by any other technologies superior

是的,语义Web的应用是最有说服力的. 在每年的ISWC会议都有一个Semantic Web Challenge, 就是看谁的SW应用最牛.去年的冠军是CS AKTive Space(http://triplestore.aktors.org/SemanticWebChallenge/).
