After making some changes in my automated dictionary creation system, I ran a test to validate the word choice for the new immigration dictionary. Latest version contains fewer intuitively negative words with positive scores, unlike the original version.
The test was performed by comparing the computer content-analysis with human coding of the 2010 UK manifestos. X is the automated coding by the dictionary and Y is the human coding. Green and Conservative are off the 45-degree line, but still the automated coding is strongly corresponding to human coding.
