Polyfuse

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

Usage

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/.
