getScore

public double getScore(long subsetFreq,
 long subsetSize,
 long supersetFreq,
 long supersetSize)

Indicates the significance of a term in a sample by determining what percentage of all occurrences of a term are found in the sample.

Specified by:

getScore in class SignificanceHeuristic

Parameters:

subsetFreq - The frequency of the term in the selected sample

subsetSize - The size of the selected sample (typically number of docs)

supersetFreq - The frequency of the term in the superset from which the sample was taken

supersetSize - The size of the superset from which the sample was taken (typically number of docs)

Returns:

a "significance" score

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
