Anserini Regressions: ClueWeb12

Models: various bag-of-words approaches

This page describes regressions for the Web Tracks from TREC 2013 and 2014 using the (full) ClueWeb12 collection. 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 cw12

Indexing

Typical indexing command:

target/appassembler/bin/IndexCollection \
  -collection ClueWeb12Collection \
  -input /path/to/cw12 \
  -index indexes/lucene-index.cw12/ \
  -generator DefaultLuceneDocumentGenerator \
  -threads 44 -storeRaw \
  >& logs/log.cw12 &

The directory /path/to/cw12/ should be the root directory of the (full) ClueWeb12 collection, i.e., /path/to/cw12/ should contain Disk1, Disk2, Disk3, Disk4.

For additional details, see explanation of common indexing options.

Retrieval

Topics and qrels are stored here, which is linked to the Anserini repo as a submodule. They are downloaded from NIST:

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

target/appassembler/bin/SearchCollection \
  -index indexes/lucene-index.cw12/ \
  -topics tools/topics-and-qrels/topics.web.201-250.txt \
  -topicreader Webxml \

  -output runs/run.cw12.bm25.topics.web.251-300.txt \
  -bm25 &

Evaluation can be performed using trec_eval and gdeval.pl:
