+# Anserini: Regressions for [DL19 (Doc)](https://trec.nist.gov/data/deep2019.html) Segmented w/ uniCOIL
+
+This page describes experiments, integrated into Anserini's regression testing framework, for the TREC 2019 Deep Learning Track (Document Ranking Task) on the MS MARCO document collection using relevance judgments from NIST.
+These runs use the uniCOIL model described in the following paper:
+
+> Jimmy Lin and Xueguang Ma. [A Few Brief Notes on DeepImpact, COIL, and a Conceptual Framework for Information Retrieval Techniques.](https://arxiv.org/abs/2106.14807) _arXiv:2106.14807_.
+
+The experiments on this page are not actually reported in the paper.
+However, the model is the same, applied to the MS MARCO _segmented_ document corpus (with doc2query-T5 expansions).
+Retrieval uses MaxP technique, where we select the score of the highest-scoring passage from a document as the score for that document to produce a document ranking.
+
+The exact configurations for these regressions are stored in [this YAML file](../src/main/resources/regression/dl19-doc-segmented-unicoil.yaml).
+Note that this page is automatically generated from [this template](../src/main/resources/docgen/templates/dl19-doc-segmented-unicoil.template) as part of Anserini's regression pipeline, so do not modify this page directly; modify the template instead.
+
+## Indexing
+
+Typical indexing command:
+
+```
+target/appassembler/bin/IndexCollection \
+  -collection JsonVectorCollection \
+  -input /path/to/msmarco-doc-segmented-unicoil \
+  -index indexes/lucene-index.msmarco-doc-segmented-unicoil/ \
+  -generator DefaultLuceneDocumentGenerator \
+  -threads 16 -impact -pretokenized \
+  >& logs/log.msmarco-doc-segmented-unicoil &
+```
+
+The directory `/path/to/msmarco-doc-segmented-unicoil/` should be a directory containing the compressed `jsonl` files that comprise the corpus.
+
+For additional details, see explanation of [common indexing options](common-indexing-options.md).
+
+## Retrieval
+
+Topics and qrels are stored in [`src/main/resources/topics-and-qrels/`](../src/main/resources/topics-and-qrels/).
+The regression experiments here evaluate on the 43 topics for which NIST has provided judgments as part of the TREC 2019 Deep Learning Track.
+The original data can be found [here](https://trec.nist.gov/data/deep2019.html).
+
+After indexing has completed, you should be able to perform retrieval as follows:
+
+```
+target/appassembler/bin/SearchCollection \
+  -index indexes/lucene-index.msmarco-doc-segmented-unicoil/ \
+  -topics src/main/resources/topics-and-qrels/topics.dl19-doc.unicoil.0shot.tsv.gz -topicreader TsvInt \
+  -output runs/run.msmarco-doc-segmented-unicoil.unicoil.topics.dl19-doc.unicoil.0shot.tsv.gz \
+  -impact -pretokenized -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &
+```
+
+Evaluation can be performed using `trec_eval`:
+
+```
+tools/eval/trec_eval.9.0.4/trec_eval -c -m map -c -m recall.100 -c -m ndcg_cut.10 src/main/resources/topics-and-qrels/qrels.dl19-doc.txt runs/run.msmarco-doc-segmented-unicoil.unicoil.topics.dl19-doc.unicoil.0shot.tsv.gz
+```
+
+## Effectiveness
+

+## Indexing
+
+Typical indexing command:
+
+```
+target/appassembler/bin/IndexCollection \
+  -collection JsonVectorCollection \
+  -input /path/to/msmarco-doc-segmented-unicoil \
+  -index indexes/lucene-index.msmarco-doc-segmented-unicoil/ \
+  -generator DefaultLuceneDocumentGenerator \
+  -threads 16 -impact -pretokenized \
+  >& logs/log.msmarco-doc-segmented-unicoil &
+```
+
+The directory `/path/to/msmarco-doc-segmented-unicoil/` should be a directory containing the compressed `jsonl` files that comprise the corpus.
+
+For additional details, see explanation of [common indexing options](common-indexing-options.md).
+
+## Retrieval
+
+Topics and qrels are stored in [`src/main/resources/topics-and-qrels/`](../src/main/resources/topics-and-qrels/).
+The regression experiments here evaluate on the 6980 dev set questions; see [this page](experiments-msmarco-passage.md) for more details.
+
+After indexing has completed, you should be able to perform retrieval as follows:
+
+```
+target/appassembler/bin/SearchCollection \
+  -index indexes/lucene-index.msmarco-doc-segmented-unicoil/ \
+  -topics src/main/resources/topics-and-qrels/topics.msmarco-doc.dev.unicoil.tsv.gz -topicreader TsvInt \
+  -output runs/run.msmarco-doc-segmented-unicoil.unicoil.topics.msmarco-doc.dev.unicoil.tsv.gz \
+  -impact -pretokenized -hits 10000 -selectMaxPassage -selectMaxPassage.delimiter "#" -selectMaxPassage.hits 1000 &
+```
+
+Evaluation can be performed using `trec_eval`:
+
+```
+tools/eval/trec_eval.9.0.4/trec_eval -c -m map -c -m recall.100 -c -m recall.1000 src/main/resources/topics-and-qrels/qrels.msmarco-doc.dev.txt runs/run.msmarco-doc-segmented-unicoil.unicoil.topics.msmarco-doc.dev.unicoil.tsv.gz

+
+The experiments on this page are not actually reported in the paper.
+However, the model is the same, applied to the MS MARCO _segmented_ document corpus (with doc2query-T5 expansions).
