(links + documents)
The Web of Documents
• A global network of linked documents

• A place where anyone can say anything about anything

• A vast collection of human-readable knowledge (and
  opinion)

• Documents are linked, but links are not qualified

This is great,
but it will only take us so far...
The issue...
• Humans are interested in things, not just documents.
The other issue...
• Humans can read documents and obtain meaning

• Machines can’t
If machines
understand the web,
  they can help us
 understand things.
