Anserini: Regressions for MS MARCO (V2) Document Ranking

This page documents regression experiments for document ranking on the segmented version of the MS MARCO (V2) document corpus, 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 MsMarcoV2DocCollection \
 -input /path/to/msmarco-v2-doc-segmented \
 -index indexes/lucene-index.msmarco-v2-doc-segmented.pos+docvectors+raw \
 -generator DefaultLuceneDocumentGenerator \
 -threads 18 -storePositions -storeDocvectors -storeRaw \
  >& logs/log.msmarco-v2-doc-segmented &

The directory /path/to/msmarco-v2-doc-segmented/ 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 in src/main/resources/topics-and-qrels/. These regression experiments use the dev queries.

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

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-v2-doc-segmented.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-v2-doc.dev.txt \
 -output runs/run.msmarco-v2-doc-segmented.bm25-default.topics.msmarco-v2-doc.dev.txt \
 -bm25 -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-v2-doc-segmented.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-v2-doc.dev.txt \
 -output runs/run.msmarco-v2-doc-segmented.bm25-default+rm3.topics.msmarco-v2-doc.dev.txt \
 -bm25 -rm3 -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-v2-doc-segmented.pos+docvectors+raw \
 -topicreader TsvInt -topics src/main/resources/topics-and-qrels/topics.msmarco-v2-doc.dev.txt \
 -output runs/run.msmarco-v2-doc-segmented.bm25-default+ax.topics.msmarco-v2-doc.dev.txt \
 -bm25 -axiom -axiom.deterministic -rerankCutoff 20 -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.msmarco-v2-doc-segmented.pos+docvectors+raw \

 -bm25 -bm25prf -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &

Evaluation can be performed using trec_eval:
