I think this may be an artifact of me trying to explain the process in symbol notation rather than as an algorithm as pseudo-code. Anyway here's how it gets calculated.

There are two chunks with n=2 before and after sentiment words. The comma stops a window around the sentiment word so we have:

chunk1 = "you're crazy"
chunk2 = "but I love you"
Now we calculate A for each which is amplification. chunk one has no amplifiers so it is not amplified. The but contractions are treated as amplifiers and so A for chunk2 is:

A = ((1 - w_neg) * a)_amp.weight
A = 1_1.9*.8
A = 1.52
Where:
w_neg = neg %% 2
a = 1 + but.weight

So now we can calculate the chunk prime which I give as: c′i, j = ∑((1 + wamp + wdeamp)⋅wi, j, kp(−1)2 + wneg)

so:

chunk1' = 1 * -1 * (-1)^2 = -1
chunk2' = 2.52 * 1 * (-1)^2 = 2.52
now we can do (chunk1' + chunk2')/(n^.5):

(-1 + 2.52)/sqrt(6) = .6205374
