Anserini: Regressions for MS MARCO Passage Retrieval

This page documents regression experiments for the MS MARCO Passage Retrieval Task, which is integrated into Anserini's regression testing framework. For more complete instructions on how to run end-to-end experiments, 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.

Indexing

Typical indexing command:

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

The directory /path/to/msmarco-passage/ should be a directory containing jsonl files converted from the official passage collection, which is in tsv format. This page explains how to perform this conversion.

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.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-passage.dev-subset.txt \

Evaluation can be performed using trec_eval:

Effectiveness

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

MAP	BM25 (Default)	+RM3	+Ax	+PRF	BM25 (Tuned)	+RM3	+Ax	+PRF
MS MARCO Passage Ranking: Dev Queries	0.1926	0.1661	0.1625	0.1520	0.1958	0.1762	0.1699	0.1582

R@1000	BM25 (Default)	+RM3	+Ax	+PRF	BM25 (Tuned)	+RM3	+Ax	+PRF
MS MARCO Passage Ranking: Dev Queries	0.8526	0.8606	0.8747	0.8537	0.8573	0.8687	0.8809	0.8561

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=0.68. See this page for more details. Note that these results are slightly different from the above referenced page because those experiments make up "fake" scores when converting runs from MS MARCO format into TREC format for evaluation by trec_eval.
