Semantics from greek semantikos is the study of meaning

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.

From wikipedia


Semantics from greek semantikos is the study of meaning

Semantics nowadays: Google


Semantics from greek semantikos is the study of meaning

Example: hot dog


Semantics from greek semantikos is the study of meaning

we want to find things on the web-> Google search for ‘hot dog’


Semantics from greek semantikos is the study of meaning

Google sifts through trillions of web pages which it has come to understand


Semantics from greek semantikos is the study of meaning

Hot dog

Hot dog ???

Google links what it thinks we mean

by a search phrase with what it thinks

a web page is about.


Semantics from greek semantikos is the study of meaning

What is happening is Google is looking for

‘Machine readable information’


Semantics from greek semantikos is the study of meaning

It’s trying to work out what things mean.


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 ?

A story about the Semantic Web http://youtu.be/bd8zR0v7Jts


Semantics from greek semantikos is the study of meaning

The web is moving from being a series of closed monolithic pages of information that we hop across like stepping stones


Semantics from greek semantikos is the study of meaning

to being tiny particles of information aggregated and aligned with whatever purpose we have so that we will be able to swim through it like water.


Semantics from greek semantikos is the study of meaning

This transition starts in the code:by separating out the core elements

of web pages

Content

Content

Here’s the information


Structure

Structure

Here’s the context of the information, how it should be labeled and classified


Presentation

Presentation

Here’s how that information should be presented for a particular device and audience looking at it.


Semantics from greek semantikos is the study of meaning

This simple idea of taking content and using code to give it structure and then applying appropriate presentation is at the heart of where the web is going.


Semantics from greek semantikos is the study of meaning

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.


Semantics from greek semantikos is the study of meaning

we can understand and re-use the content in machine readable ways


Semantics from greek semantikos is the study of meaning

Result -> more effective, more accurate, more ubiquitous information


Semantics from greek semantikos is the study of meaning

So, effective communication requires understanding of every level of web design


Semantics from greek semantikos is the study of meaning

Technical, cultural, visual, linguistic, semantic, economic, taxonomic and more
