Searching the web

The web is probably the most used knowledge repository

Searching the web is a pain:

• many search engines
• lacking semantics both in indexing (<meta> tags often ignored, spiders can't capture the semantics) and in searching (keyword searching and context operators)

Richer expressions allow to distinguish between:

• Julius the 2^nd patron of Michelangelo
• Julius the 2^nd depicted by Michelangelo

documents when searching for:

• "Julius the 2^nd" AND "Michelangelo"

Can we trust in the information coming from the web?
