Anserini: Regressions for MS MARCO (Document)
This page documents regression experiments for the MS MARCO Document Ranking 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.
Typical indexing command:
nohup sh target/appassembler/bin/IndexCollection -collection TrecCollection \
-generator LuceneDocumentGenerator -threads 1 -input /path/to/msmarco-doc -index \
lucene-index.msmarco-doc.pos+docvectors+rawdocs -storePositions -storeDocvectors \
-storeRawDocs >& log.msmarco-doc.pos+docvectors+rawdocs &
The directory /path/to/msmarco-doc/ should be a directory containing the official document collection (a single file), in TREC format.
For additional details, see explanation of common indexing options.
Topics and qrels are stored in src/main/resources/topics-and-qrels/.
The regression experiments here evaluate on the 5193 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 -topicreader TsvInt -index lucene-index.msmarco-doc.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.msmarco-doc.dev.txt -output run.msmarco-doc.bm25-default.topics.msmarco-doc.dev.txt -bm25 &

Evaluation can be performed using trec_eval:
eval/trec_eval.9.0.4/trec_eval -m map -c -m recall.1000 -c src/main/resources/topics-and-qrels/qrels.msmarco-doc.dev.txt run.msmarco-doc.bm25-default.topics.msmarco-doc.dev.txt
eval/trec_eval.9.0.4/trec_eval -m map -c -m recall.1000 -c src/main/resources/topics-and-qrels/qrels.msmarco-doc.dev.txt run.msmarco-doc.bm25-default+rm3.topics.msmarco-doc.dev.txt

With the above commands, you should be able to replicate the following results:
| MAP | BM25 (Default) | +RM3 | +Ax | +PRF | BM25 (Tuned) | +RM3 | +Ax | +PRF |
|---|---|---|---|---|---|---|---|---|
| MS MARCO Document Ranking: Dev Queries | 0.2310 | 0.1632 | 0.1147 | 0.1357 | 0.2788 | 0.2289 | 0.1895 | 0.1559 |
| R@1000 | BM25 (Default) | +RM3 | +Ax | +PRF | BM25 (Tuned) | +RM3 | +Ax | +PRF |
|---|---|---|---|---|---|---|---|---|
| MS MARCO Document Ranking: Dev Queries | 0.8856 | 0.8785 | 0.8369 | 0.8471 | 0.9326 | 0.9320 | 0.9264 | 0.8758 |
The setting "default" refers the default BM25 settings of k1=0.9, b=0.4, while "tuned" refers to the tuned setting of k1=3.44, b=0.87.
See this page for more details.
Note that here we are using trec_eval to evaluate the top 1000 hits for each query; beware, the runs provided by MS MARCO organizers for reranking have only 100 hits per query.
