Computing Document similarity using nltk

Abstract:We will explore techniques to determine the amount of similarity between documents. Specifically we will look at the intuition behind tf-idf and cosine similarity. With that as a foundation we will see how to compute these metrics with the natural language tool kit.

    Thanks for the great talk! Could someone please point me to where I might be able to find the slides that were presented in the talk?

      I can do better. The speaker was kind enough to record the talk again for those who couldn't attend. How cool is that? Here's a link to the talk: https://plus.google.co...­

    Glenn,
    Do you think you might do this one again & arrange for a larger space?

    March 27, 2014

    • Glen J.

      We don't really get a bigger space than this unfortunately (although there was a large exception to this rule in January and we got a huge space for Guido's talk). I'm sorry that we can't fit all 200 people in the room

      Kim, The good news is that the speaker was kind enough to record the video again for those who didn't make it. How cool is that? Here is a link to that video: https://plus.google.co...­

    Very practical talk, clearly presented, with lots of ideas that were neither too simple nor too hard.

    For those just reading, our host called and changed rooms. There are great signs to tell us where. Oh, and it hosts 300 people -- everyone can go!
