An article in W3 says that Semantic Web is not AI.
But an article on Knowledge representation in Wikipedia says, this:
# RDF is a simple notation for representing relationships between and among objects
Examples of artificial languages intended for knowledge representation include:
Both SW related technologies figure in an article related to AI!
The confusion seems to be in the interpretation of what is meant by AI. This word could be interpreted at 2 different levels. I could either call robots with their own intelligence as AI, or just the representation of information and infering from it as AI.
But this thought definitely needs some grinding and digesting.
