07/2010 - 10/2009	Scribd's automatic table of contents extraction Whenever you upload a document to Scribd, we perform a lot of automatic analysis: Page numbers are detected, and the the table of contents is extracted. Those two things I wrote using the mrscake machine learning library and some natural language processing.
