Models: various bag-of-words approaches on segmented documents
This page describes experiments, integrated into Anserini's regression testing framework, on the TREC 2023 Deep Learning Track document ranking task using the MS MARCO V2.1 segmented document corpus, which was derived from the MS MARCO V2 segmented document corpus and prepared for the TREC 2024 RAG Track.
Note that the NIST relevance judgments provide far more relevant documents per topic, unlike the "sparse" judgments provided by Microsoft (these are sometimes called "dense" judgments to emphasize this contrast). An important caveat is that these document judgments were inferred from the passages. That is, if a passage is relevant, the document containing it is considered relevant.
Here, we cover bag-of-words baselines where each segment in the MS MARCO V2.1 segmented document corpus is treated as a unit of indexing.
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 dl23-doc-segmented-msmarco-v2.1Typical indexing command:
bin/run.sh io.anserini.index.IndexCollection \
-threads 24 \
-collection MsMarcoV2DocCollection \
-input /path/to/msmarco-v2.1-doc-segmented \
-generator DefaultLuceneDocumentGenerator \
-index indexes/lucene-inverted.msmarco-v2.1-doc-segmented/ \
-storeRaw \
>& logs/log.msmarco-v2.1-doc-segmented &The value of -input 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.
Topics and qrels are stored here, which is linked to the Anserini repo as a submodule. The regression experiments here evaluate on the 82 topics for which NIST has provided inferred judgments as part of the TREC 2023 Deep Learning Track, but projected over to the V2.1 version of the corpus.
After indexing has completed, you should be able to perform retrieval as follows:
