This page documents BM25 regression experiments for HC4 (v1.0) Chinese topics on the NeuCLIR22 translated Chinese corpus. The HC4 qrels have been filtered down to include only those in the intersection of the HC4 and NeuCLIR22 corpora. To be clear, the queries are in English and the corpus is in English (automatically translated by the organizers using Sockeye).
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 hc4-neuclir22-zh-en
The HC4 corpus can be downloaded following the instructions here.
After download, verify that all and only specified documents have been downloaded by running the code provided 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 hc4-neuclir22-zh-en \
--corpus-path collections/neuclir22-zh-enTypical indexing command:
bin/run.sh io.anserini.index.IndexCollection \
-collection NeuClirCollection \
-input /path/to/neuclir22-zh-en \
-generator DefaultLuceneDocumentGenerator \
-index indexes/lucene-index.neuclir22-zh-en \
-threads 8 -storePositions -storeDocvectors -storeRaw \
>& logs/log.neuclir22-zh-en &
See this page for more details about the HC4 corpus. For additional details, see explanation of common indexing options.
