3. Purpose
 To improve meaning of the Kno.e.sis Web pages to
search engines by introducing metadata annotations
 Annotate:
 People pages
 Library pages
 News pages
 General site
navigation

4. Annotation = Meaning
 No metadata – No meaning to the search engine
Web Browser Human
<div> Organization
<h2> Date
<p> Information
 Metadata annotations – Meaning for search engines
 Rich snippets
 How? RDF, Microdata, Microformats
 Schema.org specification – Google, Yahoo, Bing
