Anserini Regressions: MS MARCO (V2) Document Ranking

Models: BM25 on segmented documents with doc2query-T5 expansions

This page describes regression experiments for document ranking on the segmented version of the MS MARCO (V2) document corpus using the dev queries, which is integrated into Anserini's regression testing framework. Here, we expand the segmented document corpus with doc2query-T5.

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-doc-segmented-d2q-t5

Indexing

Typical indexing command:

target/appassembler/bin/IndexCollection \
  -collection MsMarcoV2DocCollection \
  -input /path/to/msmarco-v2-doc-segmented-d2q-t5 \
  -index indexes/lucene-index.msmarco-v2-doc-segmented-d2q-t5/ \
  -generator DefaultLuceneDocumentGenerator \
  -threads 24 -storePositions -storeDocvectors -storeRaw \
  >& logs/log.msmarco-v2-doc-segmented-d2q-t5 &

The directory /path/to/msmarco-v2-doc-segmented-d2q-t5/ 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 and the dev2 queries.

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

target/appassembler/bin/SearchCollection \
  -index indexes/lucene-index.msmarco-v2-doc-segmented-d2q-t5/ \
  -topics src/main/resources/topics-and-qrels/topics.msmarco-v2-doc.dev.txt \
  -topicreader TsvInt \
  -output runs/run.msmarco-v2-doc-segmented-d2q-t5.bm25-default.topics.msmarco-v2-doc.dev.txt \
  -bm25 -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &
target/appassembler/bin/SearchCollection \
  -index indexes/lucene-index.msmarco-v2-doc-segmented-d2q-t5/ \
  -topics src/main/resources/topics-and-qrels/topics.msmarco-v2-doc.dev2.txt \
  -topicreader TsvInt \
  -output runs/run.msmarco-v2-doc-segmented-d2q-t5.bm25-default.topics.msmarco-v2-doc.dev2.txt \
  -bm25 -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &

Evaluation can be performed using trec_eval:
