| Method Summary |
|
| public void | addResult(int n, boolean isRelevant, long docNameExtractTime)
Add a (possibly relevant) doc. |
| public static QualityStats | average(QualityStats[] stats)
Create a QualityStats object that is the average of the input QualityStats objects. |
| public double | getAvp()
Return the average precision at recall points. |
| public long | getDocNamesExtractTime()
Returns the time it took to extract doc names for judging the measured query, in milliseconds. |
| public double | getMRR()
Returns the Mean reciprocal rank over the queries or RR for a single query.
Reciprocal rank is defined as 1/r where r is the
rank of the first correct result, or 0 if there are no correct
results within the top 5 results. |
| public double | getMaxGoodPoints()
Returns the maximal number of good points. |
| public double | getNumGoodPoints()
Returns the number of good points (only relevant points). |
| public double | getNumPoints()
Returns the number of points (both relevant and irrelevant points). |
| public double | getPrecisionAt(int n)
Return the precision at rank n:
|{relevant hits within first n hits}| / n.
Parameters:
n - requested precision point, must be at least 1 and at most QualityStats.MAX_POINTS. |
| public double | getRecall()
Return the recall: |{relevant hits}| / |{hits}|. |
| public RecallPoint[] | getRecallPoints()
Returns the recallPoints. |
| public long | getSearchTime()
Returns the search time in milliseconds for the measured query. |
| public void | log(String title, int paddLines, PrintWriter logger, String prefix)
Log information on this QualityStats object. |
