NTCIREVAL by Tetsuya Sakai

NTCIREVAL is a toolkit for computing various retrieval effectiveness metrics.
It can be used for NTCIR and TREC ad hoc retrieval evaluation, diversified search evaluation, NTCIR-8 Community QA Task evaluation and so on.

NTCIREVAL can compute metrics such as:

-Average Precision



-Expected Reciprocal Rank (ERR)

-Graded Average Precision (GAP)

-Rank-Biased Precision (RBP)

-Expected Blended Ratio (EBR)

-intentwise Rank-Biased Utility (iRBU)

-Normalised Cumulative Utility (NCU)

-Condensed-List versions of the above metrics


-D#-measures and DIN#-measures for diversity evaluation

-Intent-Aware (IA) metrics and P+Q# for diversity evaluation


For details, please refer to the README file included in the tar file.



(A minor update to avoid a warning message at compilation time; a few normalised measuresd added)


(New measures EBR and iRBU implemented; a script for computing measures based on continuous gain values added)


(Fixed a very minor bug that does not affect measure computations)


(Fixed a bug introduced in 161017; added a few evaluation measures)
