Class ScoredEvaluationCountsArray

java.lang.Object

org.aksw.gerbil.matching.scored.ScoredEvaluationCountsArray

public class ScoredEvaluationCountsArray
extends Object

This structure contains the evaluation counts of several documents with several confidence thresholds. The main mapping is from an array of confidence scores (= thresholds) to the results. The results are available as sums, e.g., truePositiveSums, or as document-wise counts, e.g., truePositives.
