什么时候能够恰如其分的应用语义网技术、什么时候应该应用语义网技术,这一直是个困扰我的问题。John Black给出了他的答案:
In cases where the data needed to operate effectively is distributed widely, changes rapidly, and can not or must not be combined in any way that would allow it to be controlled, semantic web technologies are essential. In such circumstances, all of the data needed must be created and maintained by the separate parties involved. But the most valuable results will be obtained by combining it all together, in real time. Problems of this sort are what the semantic web vision addresses.
