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 elsif    mood == positive && probability > 0.79    score = 88 elsif    mood == positive && probability > 0.74    score = 86 elsif    mood == positive && probability > 0.69    score = 84 elsif    mood == positive && probability > 0.64    score = 82 elsif    mood == positive && probability > 0.59    score = 80 elsif    mood == positive && probability > 0.54    score = 78 elsif    mood == positive && probability > 0.49    score = 76 elsif    mood == positive && probability > 0.44    score = 74 elsif    mood == positive && probability > 0.39    score = 72 elsif    mood == positive && probability > 0.34    score = 70 elsif    mood == positive && probability > 0.29    score = 68 elsif    mood == positive && probability > 0.24    score = 66 elsif    mood == positive && probability > 0.19    score = 64 elsif    mood == positive && probability > 0.14    score = 62 elsif    mood == positive && probability > 0    score = 60 elsif    mood == neutral && probability > 0.94    score = 59 elsif   mood == neutral && probability > 0.89   score = 58 elsif   mood == neutral && probability > 0.84   score = 57 elsif   mood == neutral && probability > 0.79   score = 56 elsif   mood == neutral && probability > 0.74   score = 55 elsif   mood == neutral && probability > 0.69   score = 53 elsif   mood == neutral && probability > 0.64   score = 52 elsif   mood == neutral && probability > 0.59   score = 51 elsif   mood == neutral && probability > 0.54   score = 50 elsif   mood == neutral && probability > 0.49   score = 49 elsif   mood == neutral && probability > 0.44   score = 48 elsif   mood == neutral && probability > 0.39   score = 47 elsif   mood == neutral && probability > 0.34   score = 46 elsif   mood == neutral && probability > 0.29   score = 45 elsif   mood == neutral && probability > 0.24   score = 43 elsif   mood == neutral && probability > 0.19   score = 42 elsif   mood == neutral && probability > 0.14   score = 41 elsif   mood == neutral && probability > 0   score = 40 elsif   mood == negative && probability > 0.94   score = 39 elsif   mood == negative && probability > 0.89   score = 38 elsif   mood == negative && probability > 0.84   score = 36 elsif   mood == negative && probability > 0.79   score = 34 elsif   mood == negative && probability > 0.74   score = 32 elsif   mood == negative && probability > 0.69   score = 30 elsif   mood == negative && probability > 0.64   score = 28 elsif   mood == negative && probability > 0.59   score = 26 elsif   mood == negative && probability > 0.54   score = 24 elsif   mood == negative && probability > 0.49   score = 22 elsif   mood == negative && probability > 0.44   score = 20 elsif   mood == negative && probability > 0.39   score = 18 elsif   mood == negative && probability > 0.34   score = 16 elsif   mood == negative && probability > 0.29   score = 14 elsif   mood == negative && probability > 0.24   score = 12 elsif   mood == negative && probability > 0.19   score = 10 elsif   mood == negative && probability > 0.14   score = 8 else   mood == negative && probability > 0   score = 3 end

    @Simpleton : have you looked up Lagrange interpolation for one variable? If yes then the idea is the same but your case is for 2 variables, that's all I am trying to say.2012-01-25
