OpenNIR

An end-to-end neural ad-hoc ranking pipeline.

Quick start

OpenNIR requires Python 3.6 (not tested with other versions). Java 11 is required (for Anserini).

  • OpenNIR can also be run in Docker; you can find instructions here.

Install dependencies

pip install -r requirements.txt

Train and validate a model (here, ConvKNRM on ANTIQUE):

scripts/pipeline.sh config/conv_knrm config/antique

(Performance on the test set can be obtained by adding pipeline.test=True)

Grid serach for BM25 over ANTIQUE for comparision with neural model performance:

scripts/pipeline.sh config/grid_search config/antique

(Performance on the test set can be obtained by adding pipeline.test=True)

Models, datasets, and vocabularies will be saved in ~/data/onir/. This can be overridden by setting data_dir=~/some/other/place/ as a command line argument, in a configuration file, or in the ONIR_ARGS environment variable.
