How is SEO changing to support microdata like Schema.org? And why is this metadata good for information retrieval and organic search engine optimization?
In this introductory guest lecture for the University of Washington, I present some of the problems in information retrieval for unstructured content ("blobs") and how to solve for these challenges using Schema.org microdata to define "entities".
