Anserini: Regressions for Gov2
This page describes regressions for the Terabyte Tracks from TREC 2004 to 2006, which uses the Gov2 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.
Typical indexing command:
nohup sh target/appassembler/bin/IndexCollection -collection TrecwebCollection -input /path/to/gov2 \
-index indexes/lucene-index.gov2.pos+docvectors+raw -generator DefaultLuceneDocumentGenerator -threads 44 \
-storePositions -storeDocvectors -storeRaw >& logs/log.gov2.pos+docvectors+rawdocs &
The directory /path/to/gov2/ should be the root directory of the Gov2 collection, i.e., ls /path/to/gov2/ should bring up a bunch of subdirectories, GX000 to GX272.
For additional details, see explanation of common indexing options.
Topics and qrels are stored in src/main/resources/topics-and-qrels/, downloaded from NIST:
