May 6th Primary Speech Cloud Comparison

By: Jeff Clark    Date: Wed, 07 May 2008

I have taken the speeches delivered by both Obama and Clinton last night after the May 6th primary results and used them to build a Document Cloud Comparison. It shows which words were used together by each speaker using linked word clouds. A static image is shown below for references to the word 'change' to give you a flavour but the real fun comes with exploring the interactive application.

If you enter a blank focus string in the application it shows a standard word cloud and colors words that are unique to one speaker or the other. The top words used by Obama and not by Clinton include 'side' , 'down', 'government', 'values', 'yes', 'lead' , 'life', 'kind', 'trust', and 'united' . Those used by Clinton uniquely include 'keep', 'feel', 'journey', 'working', 'invisible', 'west', and 'story'.

Give it a try yourself. The application is written in Java so you may have to wait a few seconds for it to start up.
