Anserini: Regressions for ClueWeb12

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.

Indexing

Typical indexing command:

nohup sh target/appassembler/bin/IndexCollection -collection ClueWeb12Collection -input /path/to/cw12 \
 -index indexes/lucene-index.cw12.pos+docvectors+raw -generator DefaultLuceneDocumentGenerator -threads 44 \
 -storePositions -storeDocvectors -storeRaw >& logs/log.cw12.pos+docvectors+rawdocs &

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 in src/main/resources/topics-and-qrels/, downloaded from NIST:

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

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.cw12.pos+docvectors+raw \
 -topicreader Webxml -topics src/main/resources/topics-and-qrels/topics.web.201-250.txt \
 -bm25 -output run.cw12.bm25.topics.web.201-250.txt &
nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.cw12.pos+docvectors+raw \
 -topicreader Webxml -topics src/main/resources/topics-and-qrels/topics.web.251-300.txt \
 -bm25 -output run.cw12.bm25.topics.web.251-300.txt &

nohup target/appassembler/bin/SearchCollection -index indexes/lucene-index.cw12.pos+docvectors+raw \
