Semantics means relating to meaning in
language or logic
HTML descibes the syntax not the semantics
The Semantic Web
An extension of the current Web that
provides an easier way to find, share, reuse and
combine information more easily
History• The concept of the Semantic
Network Model was formed in the early 1960s by people of different professions by publishing about them
• The term "Semantic Web" was coined by Tim Berners-Lee in 2008
• Schema.org launched on June 2, 2011 by Bing, Google and Yahoo to provides a collection of schemas to improves the display of search results
Purpose
The Semantic Web was envisioned as a system that enables machines to "understand" and respond to complex human requests based on their meaning
It is regarded as an integrator across different content, information applications and systems
Whose job is it ?
The Webmaster's as its their site and they need newer applications to understand
them
How do we get semantic web
• Applications getting better at understanding human semantics (‘Top Down’)
• More structured formats are gaining wider use (‘Bottom Up’)
• More database driven sites, so less need for humans to understand it all
• ‘Semantic web’ applications appearing
Top Down
Depends of ‘more intelligent’ computers–Google Book Search–LibX Toolbar
Bottom Up
Depends on more structured data using agreed standards–URIs–RDF–OWL–HTML5 microformat–SPARQL
Advantages
• Premanent increase in data quality
• Better search visibility and higher ranking
• Empower collaboration, data sharing and integration for bussiness applications
ChallengesSome of the challenges of semantic web include –Vastness–Vagueness–Uncertainity–Inconsistency –Deciet
