From the description:
Video reviews the OCR (Optical Character Recognition) extractor and the Alchemy API Entity extractor of Wandora application. First, the OCR extractor is used to recognize text out of PNG images. Next the Alchemy API Entity extractor is used to recognize entities out of the text. Wandora is an open source tool for people who collect and process information, especially networked knowledge and knowledge about WWW resources. For more information see http://wandora.org.
A great demo of some of the many options of Wandora! (Wandora has more options than a Swiss army knife.)
It is an impressive demonstration.
If you aren’t familiar with Wandora, take a close look at it: http://wandora.org.
