Edited:
I want to get a sentiment score of various sentences and I've tried coming up with an equation that could satisfy the conditions that are inherent to each sentence (It's estimated mood as well as a probability of each mood) that are determined by a 3rd part service. The value I want to get - the score - gets its value from these 2 conditions or variables - the mood with 3 states (either positive, neutral, negative) and a probability for each (0.0 - 1.0), which gives the score a possible range from 0 - 100. I added the score values in myself, so they aren't an exact science, but the ranges worked out to be 0-39 for negative moods, 40-60 for neutral moods, and up to 100 for positive moods, as a continuum. I'm hoping to get something like the following that will make the scores roughly similar to those set out below:
score = mood * probability * (some kind of weighting)
Rough score values:
if mood == positive && probability > 0.94
score = 100
elsif
mood == positive && probability > 0.89
score = 96
elsif
mood == positive && probability > 0.84
score = 92

score = 88
