Anserini Regressions: MS MARCO (V2) Passage Ranking

Models: various bag-of-words approaches on augmented passages

This page describes regression experiments for passage ranking on the augmented version of the MS MARCO V2 passage corpus using the dev queries, which is integrated into Anserini's regression testing framework. Here, we cover bag-of-words baselines. For additional instructions on working with the MS MARCO V2 passage corpus, refer to this page.

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 msmarco-v2-passage-augmented

Indexing

Typical indexing command:

bin/run.sh io.anserini.index.IndexCollection \
  -collection MsMarcoV2PassageCollection \
  -input /path/to/msmarco-v2-passage-augmented \
  -generator DefaultLuceneDocumentGenerator \
  -index indexes/lucene-inverted.msmarco-v2-passage-augmented/ \
  -threads 24 -storeRaw \
  >& logs/log.msmarco-v2-passage-augmented &

The directory /path/to/msmarco-v2-passage-augmented/ should be a directory containing the compressed jsonl files that comprise the corpus. See this page for additional details.

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.

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-v2-passage-augmented/ \
  -topics tools/topics-and-qrels/topics.msmarco-v2-passage.dev.txt \
  -topicReader TsvInt \
  -output runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev.txt \
  -bm25 &
bin/run.sh io.anserini.search.SearchCollection \
  -index indexes/lucene-inverted.msmarco-v2-passage-augmented/ \
  -topics tools/topics-and-qrels/topics.msmarco-v2-passage.dev2.txt \
  -topicReader TsvInt \
  -output runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev2.txt \
  -bm25 &

Evaluation can be performed using trec_eval:

bin/trec_eval -c -m recall.100 tools/topics-and-qrels/qrels.msmarco-v2-passage.dev.txt runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev.txt
bin/trec_eval -c -m recall.1000 tools/topics-and-qrels/qrels.msmarco-v2-passage.dev.txt runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev.txt
bin/trec_eval -c -M 100 -m map -c -M 100 -m recip_rank tools/topics-and-qrels/qrels.msmarco-v2-passage.dev.txt runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev.txt
bin/trec_eval -c -m recall.100 tools/topics-and-qrels/qrels.msmarco-v2-passage.dev2.txt runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev2.txt
bin/trec_eval -c -m recall.1000 tools/topics-and-qrels/qrels.msmarco-v2-passage.dev2.txt runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev2.txt
bin/trec_eval -c -M 100 -m map -c -M 100 -m recip_rank tools/topics-and-qrels/qrels.msmarco-v2-passage.dev2.txt runs/run.msmarco-v2-passage-augmented.bm25-default.topics.msmarco-v2-passage.dev2.txt
