Anserini: Regressions for MS MARCO Passage Retrieval

This page documents regression experiments for the MS MARCO Passage Retrieval Task with docTTTTTquery expansions. These experiments are integrated into Anserini's regression testing framework.

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.

Indexing

Typical indexing command:

nohup sh target/appassembler/bin/IndexCollection -collection JsonCollection \
 -input /path/to/msmarco-passage-docTTTTTquery \
 -index indexes/lucene-index.msmarco-passage-docTTTTTquery.pos+docvectors+raw \
 -generator DefaultLuceneDocumentGenerator \
 -threads 9 -storePositions -storeDocvectors -storeRaw \
  >& logs/log.msmarco-passage-docTTTTTquery &

The directory /path/to/msmarco-passage/ should be a directory containing jsonl files converted from the official passage collection, appended with the docTTTTTquery expansions.

For additional details, see explanation of common indexing options.

Retrieval

Topics and qrels are stored in src/main/resources/topics-and-qrels/. 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:

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-passage-docTTTTTquery.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-passage.dev-subset.txt \
 -output runs/run.msmarco-passage-docTTTTTquery.bm25-default.topics.msmarco-passage.dev-subset.txt \
 -bm25 &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-passage-docTTTTTquery.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-passage.dev-subset.txt \
 -output runs/run.msmarco-passage-docTTTTTquery.bm25-default+rm3.topics.msmarco-passage.dev-subset.txt \
 -bm25 -rm3 &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-passage-docTTTTTquery.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-passage.dev-subset.txt \
 -output runs/run.msmarco-passage-docTTTTTquery.bm25-tuned.topics.msmarco-passage.dev-subset.txt \
 -bm25 -bm25.k1 0.82 -bm25.b 0.68 &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-passage-docTTTTTquery.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-passage.dev-subset.txt \
 -output runs/run.msmarco-passage-docTTTTTquery.bm25-tuned+rm3.topics.msmarco-passage.dev-subset.txt \
 -bm25 -bm25.k1 0.82 -bm25.b 0.68 -rm3 &

Evaluation can be performed using trec_eval:

tools/eval/trec_eval.9.0.4/trec_eval -m map -c -m recall.1000 -c src/main/resources/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-docTTTTTquery.bm25-default.topics.msmarco-passage.dev-subset.txt

tools/eval/trec_eval.9.0.4/trec_eval -m map -c -m recall.1000 -c src/main/resources/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-docTTTTTquery.bm25-default+rm3.topics.msmarco-passage.dev-subset.txt

tools/eval/trec_eval.9.0.4/trec_eval -m map -c -m recall.1000 -c src/main/resources/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-docTTTTTquery.bm25-tuned.topics.msmarco-passage.dev-subset.txt

tools/eval/trec_eval.9.0.4/trec_eval -m map -c -m recall.1000 -c src/main/resources/topics-and-qrels/qrels.msmarco-passage.dev-subset.txt runs/run.msmarco-passage-docTTTTTquery.bm25-tuned+rm3.topics.msmarco-passage.dev-subset.txt

Effectiveness

With the above commands, you should be able to reproduce the following results:

MAP BM25 (Default) +RM3 BM25 (Tuned) +RM3
MS MARCO Passage Ranking: Dev Queries 0.2805 0.2243 0.2850 0.2266
R@1000 BM25 (Default) +RM3 BM25 (Tuned) +RM3
MS MARCO Passage Ranking: Dev Queries 0.9470 0.9463 0.9471 0.9479

The setting "default" refers the default BM25 settings of k1=0.9, b=0.4, while "tuned" refers to the tuned setting of k1=0.82, b=0.72 on the original passages. See this page for more details.

To reproduce the exact conditions for a leaderboard submission, retrieve using the following command:

wget https://www.dropbox.com/s/hq6xjhswiz60siu/queries.dev.small.tsv

sh target/appassembler/bin/SearchMsmarco -threads 8 \
 -index indexes/lucene-index.msmarco-passage-docTTTTTquery.pos+docvectors+raw \
 -queries queries.dev.small.tsv \
 -output runs/run.msmarco-passage-docTTTTTquery -hits 1000

Evaluate using the MS MARCO eval script:

wget https://www.dropbox.com/s/khsplt2fhqwjs0v/qrels.dev.small.tsv

python tools/scripts/msmarco/msmarco_passage_eval.py qrels.dev.small.tsv runs/run.msmarco-passage-docTTTTTquery

The results should be:

#####################
MRR @10: 0.27680089370991834
QueriesRanked: 6980
#####################

Which matches the score described in the docTTTTTquery repo and also on the official MS MARCO leaderboard.
