When I was using the Polarity-Index method a few days ago, I noticed differences in Table 3, as published.

However, it should be as in Table 3.

These changes do not affect neither the efficiency of the method nor any section of the paper.

I also noted the difficulty to compare information on the same APD2 database (November 2011), as it changes weekly. Therefore I am sending a file to support that test, in case the journal has backup for additional information. Otherwise I will to keep this information for three years.
