[Classifier4j-devel] Fwd: calculateOverallProbability Questions

[Matt C. <MCo...@my...>]

Can someone explain to me what is happening in calculateOverallProbability.

The "probability" for each word drawn into this method via calcWordsProbabilty 
is .99 if atleast one occurance of word exists in the database in the given 
category and .5 (Neutral) if the word does not occur in the given category.

This does not seem right to me.

I am not sure, when, where, how and why the probability on the words is 
getting assigned as described.

Another thing that is confusing me is that several time during to course of 
this method, the variable "z" goes to 0 (zero) and the process continues.  
Attached is the tail end of a log of this method.  If z goes to zero over and 
over, what is the point of performing this calculation.  It seems the 
calculation would only take into account those words that are processed after 
the very last time Z goes to zero.

I simply added:
System.out.println("Z : [" + z +"]  Word : [" + wps[i].getWord()+"]  
Probability : [" + wps[i].getProbability() + "]");

after each assignment of z in BayesianClassifer.calculateOverallProbability()

Also, z is recalculated on each occurence of a particular word.  Is this 
proper?
