Syntax
public class QualityStats : objectConstructors
| Name | Description |
|---|---|
| QualityStats(Double, Int64) | Construct a QualityStats object with anticipated maximal number of relevant hits. |
Fields
| Name | Description |
|---|---|
| MAX_POINTS | Number of points for which precision is computed. |
Properties
| Name | Description |
|---|---|
| DocNamesExtractTime | Returns the time it took to extract doc names for judging the measured query, in milliseconds. |
| MaxGoodPoints | Returns the maximal number of good points. This is the number of relevant docs known by the judge for the measured query. |
| MRR | Returns the Mean reciprocal rank over the queries or RR for a single query. |
| NumGoodPoints | Returns the number of good points (only relevant points). |
| NumPoints | Returns the number of points (both relevant and irrelevant points). |
| Recall | Return the recall: |{relevant hits found}| / |{relevant hits existing}|. |
| SearchTime | Returns the search time in milliseconds for the measured query. |
Methods
| Name | Description |
|---|---|
| AddResult(Int32, Boolean, Int64) | Add a (possibly relevant) doc. |
| Average(QualityStats[]) | Create a QualityStats object that is the average of the input QualityStats objects. |
| GetAvp() | Return the average precision at recall points. |
| GetPrecisionAt(Int32) | Return the precision at rank n:
|{relevant hits within first |
