This page documents BM25 regression experiments for the TREC 2022 NeuCLIR Track, Persian, using query translation (i.e., human translations provided by the organizers).
The exact configurations for these regressions are stored in this YAML file. Note that this page is automatically generated from this template as part of Anserini's regression pipeline, so do not modify this page directly; modify the template instead.
From one of our Waterloo servers (e.g., orca), the following command will perform the complete regression, end to end:
python src/main/python/run_regression.py --index --verify --search --regression neuclir22-fa-qt
The NeuCLIR 2022 corpus can be downloaded following the instructions here.
With the corpus downloaded, unpack into collections/ and run the following command to perform the remaining steps below:
python src/main/python/run_regression.py --index --verify --search --regression neuclir22-fa-qt \
--corpus-path collections/neuclir22-faTypical indexing command:
target/appassembler/bin/IndexCollection \
-collection NeuClirCollection \
-input /path/to/neuclir22-fa \
-index indexes/lucene-index.neuclir22-fa \
-generator DefaultLuceneDocumentGenerator \
-threads 8 -storePositions -storeDocvectors -storeRaw -language fa \
>& logs/log.neuclir22-fa &
For additional details, see explanation of common indexing options.
After indexing has completed, you should be able to perform retrieval as follows:
