A tool for performing popular fusion techniques on TREC run files.
The following fusion methods are supported:
- Borda count
- CombANZ
- CombMAX
- CombMED
- CombMIN
- CombMNZ
- CombSUM
- Inverse square rank
- Logarithmic inverse square rank
- Rank-biased centroids
- Reciprocal rank fusion
Fuse three runs using CombSUM with scaled normalization to depth 100:
polyfuse combsum -d 100 -n minmax a.run b.run c.run > combsum.run
To see all fusion commands and options run polyfuse -h.
To try all fusion methods run tools/sweep_polyfuse.py a.run b.run c.run and the output will be saved in fusion_output/.
