Anserini Regressions: MS MARCO Passage Ranking

Model: SPLADE++ CoCondenser-SelfDistil (using pre-encoded queries)

This page describes regression experiments, integrated into Anserini's regression testing framework, using the SPLADE++ CoCondenser-SelfDistil model on the MS MARCO passage ranking task, as described in the following paper:

Thibault Formal, Carlos Lassance, Benjamin Piwowarski, and Stéphane Clinchant. From Distillation to Hard Negative Sampling: Making Sparse Neural IR Models More Effective. Proceedings of the 45th International ACM SIGIR Conference on Research and Development in Information Retrieval, pages 2353–2359.

In these experiments, we are using pre-encoded queries (i.e., cached results of query encoding).

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 and then run bin/build.sh to rebuild the documentation.

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 msmarco-v1-passage.splade-pp-sd

We make available a version of the MS MARCO Passage Corpus that has already been encoded with SPLADE++ CoCondenser-SelfDistil.

From any machine, the following command will download the corpus and perform the complete regression, end to end:

python src/main/python/run_regression.py --download --index --verify --search --regression msmarco-v1-passage.splade-pp-sd

The run_regression.py script automates the following steps, but if you want to perform each step manually, simply copy/paste from the commands below and you'll obtain the same regression results.

Corpus Download

Download the corpus and unpack into collections/:

wget https://rgw.cs.uwaterloo.ca/pyserini/data/msmarco-passage-splade-pp-sd.tar -P collections/
tar xvf collections/msmarco-passage-splade-pp-sd.tar -C collections/

To confirm, msmarco-passage-splade-pp-sd.tar is 4.8 GB and has MD5 checksum cb7e264222f2bf2221dd2c9d28190be1. With the corpus downloaded, the following command will perform the remaining steps below:

python src/main/python/run_regression.py --index --verify --search --regression msmarco-v1-passage.splade-pp-sd \
  --corpus-path collections/msmarco-passage-splade-pp-sd

Indexing

Sample indexing command:

bin/run.sh io.anserini.index.IndexCollection \
  -collection JsonVectorCollection \
  -input /path/to/msmarco-passage-splade-pp-sd \
  -generator DefaultLuceneDocumentGenerator \
  -index indexes/lucene-inverted.msmarco-v1-passage.splade-pp-sd/ \
  -threads 16 -impact -pretokenized -storeDocvectors \
  >& logs/log.msmarco-passage-splade-pp-sd &

The path /path/to/msmarco-passage-splade-pp-sd/ should point to the corpus downloaded above.

The important indexing options to note here are -impact -pretokenized: the first tells Anserini not to encode BM25 doc lengths into Lucene's norms (which is the default) and the second option says not to apply any additional tokenization on the pre-encoded tokens. Upon completion, we should have an index with 8,841,823 documents.

For additional details, see explanation of common indexing options.

Retrieval

Topics and qrels are stored here, which is linked to the Anserini repo as a submodule. The regression experiments here evaluate on the 6980 dev set questions; see this page for more details.

After indexing has completed, you should be able to perform retrieval as follows:

bin/run.sh io.anserini.search.SearchCollection \
  -index indexes/lucene-inverted.msmarco-v1-passage.splade-pp-sd/ \
  -topics tools/topics-and-qrels/topics.msmarco-passage.dev-subset.splade-pp-sd.tsv.gz \
  -topicReader TsvInt \
  -output runs/run.msmarco-passage-splade-pp-sd.splade-pp-sd-cached_q.topics.msmarco-passage.dev-subset.splade-pp-sd.txt \
  -impact -pretokenized &

Evaluation can be performed using trec_eval:

bin/trec_eval -c -m map tools/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-splade-pp-sd.splade-pp-sd-cached_q.topics.msmarco-passage.dev-subset.splade-pp-sd.txt
bin/trec_eval -c -M 10 -m recip_rank tools/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-splade-pp-sd.splade-pp-sd-cached_q.topics.msmarco-passage.dev-subset.splade-pp-sd.txt
bin/trec_eval -c -m recall.100 tools/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-splade-pp-sd.splade-pp-sd-cached_q.topics.msmarco-passage.dev-subset.splade-pp-sd.txt
bin/trec_eval -c -m recall.1000 tools/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-splade-pp-sd.splade-pp-sd-cached_q.topics.msmarco-passage.dev-subset.splade-pp-sd.txt
