public getWriteableName()Description copied from interface:NamedWriteable
Returns the name of the writeable object -
getScore
public double getScore(long subsetFreq, long subsetSize, long supersetFreq, long supersetSize)Calculates the significance of a term in a sample against a background of normal distributions by comparing the changes in frequency. This is the heart of the significant terms feature.- Specified by:
getScore
in classSignificanceHeuristic
- Parameters:
subsetFreq
- The frequency of the term in the selected samplesubsetSize
- The size of the selected sample (typically number of docs)supersetFreq
- The frequency of the term in the superset from which the sample was takensupersetSize
- The size of the superset from which the sample was taken (typically number of docs)- Returns:
- a "significance" score
