This video was done for the course “Information Design” in summer semester 2013 at University of Technology, Vienna.
The goal was to explain a rather abstract topic in Computer Science to the “educated public”. Of course, this short animation does not tell the whole story and deliberately leaves out all the details.
The animation describes the basic idea behind the Vector Space Model and Cosine Similarity as described in great detail in: http://nlp.stanford.edu/IR-book/
And no, google doesn’t work like that 🙂
