Semantics (from Greek "σημαντικός" - semantikos) is the study of meaning.

It typically focuses on the relation between signifiers - words, phrases, signs and symbols - and what they stand for.

Hot dog ???

Google links what it thinks we mean

by a search phrase with what it thinks

a web page is about.

What is happening is Google is looking for

‘Machine readable information’

hot dog
“Hot dog”

Is this an expression? someone’s address? a name? is this information connected with that information? What is the most important entry to display? Why does “hot dog” link to that ?

slide20

Because we have used the principle of semantics to give structure to the content we can reinterpret it and present it in any format on any device we desire.
