Models: various bag-of-words approaches
This page describes regressions for the TREC 2018 Common Core Track, which uses the TREC Washington Post Corpus. 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 core18
Typical indexing command:
target/appassembler/bin/IndexCollection \
-collection WashingtonPostCollection \
-input /path/to/wapo.v2 \
-index indexes/lucene-index.wapo.v2/ \
-generator WashingtonPostGenerator \
-threads 1 -storePositions -storeDocvectors -storeRaw \
>& logs/log.wapo.v2 &
The directory /path/to/core18/
should be the root directory of the TREC Washington Post Corpus, i.e., ls /path/to/core18/
should bring up a single JSON file.
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. They are downloaded from NIST:
topics.core18.txt
: topics for the TREC 2018 Common Core Trackqrels.core18.txt
: qrels for the TREC 2018 Common Core Track
After indexing has completed, you should be able to perform retrieval as follows:
target/appassembler/bin/SearchCollection \
-index indexes/lucene-index.wapo.v2/ \
-topics tools/topics-and-qrels/topics.core18.txt \
-topicreader Trec \
-output runs/run.wapo.v2.bm25.topics.core18.txt \
-bm25 &
target/appassembler/bin/SearchCollection \
-index indexes/lucene-index.wapo.v2/ \
-topics tools/topics-and-qrels/topics.core18.txt \
-topicreader Trec \

Evaluation can be performed using trec_eval
:
tools/eval/trec_eval.9.0.4/trec_eval -m map -m P.30 tools/topics-and-qrels/qrels.core18.txt runs/run.wapo.v2.bm25.topics.core18.txt
