TREC 2018 Runbook: "Anserini" Group

This is the runbook for TREC 2018 submissions by the "Anserini" group. Note that Anserini (the system) was used by another group ("h2oloo") for a completely different set of runs.

In total, the Anserini group participated in three tracks:

  • Common Core Track
  • News Track
  • CENTRE Track

Note that this document is specifically a runbook and does not encode regression experiments. Runbooks are designed to help us (i.e., TREC participants) document the steps taken to generate a run. They are primarily designed to make experiments repeatable (i.e., by ourselves), although they might be helpful for others who wish to replicate our runs.

However, we concede that repeatability of the runs (even by us) is challenging, since the codebase is always evolving, and by the time we add proper documentation, it might be several months later. See details below... but we try our best...

Common Core Track

Building the index:

nohup target/appassembler/bin/IndexCollection \
 -collection WashingtonPostCollection \
 -input WashingtonPost.v2/data/ -generator WapoGenerator \
 -index lucene-index.core18.pos+docvectors+rawdocs \
 -threads 36 -storePositions -storeDocvectors -storeRawDocs &> \
log.core18.pos+docvectors+rawdocs &

Topics and qrels are stored in src/main/resources/topics-and-qrels/.

Commands to replicate submitted runs:

The above describes how the Anserini team generated runs for TREC 2018. However, after the submission of the runs, the Anserini codebase continued to evolved, and as of commit 3114507d863b9aadcc6660fe8257fc4d1ab6e1f4 (Wed Dec 12 12:59:25 2018 -0800), running the above commands unfortunately yields different effectiveness numbers. In the table below, we compare the effectiveness of our submitted runs, marked with * (e.g., AP*), and the effectiveness of the generated runs at the commit point referenced above, marked with + (e.g., AP+).

CENTRE Track

We participated in "Task 2: Web Track 2013". Steps to generate our runs:

In addition to the Anserini repo, the following repo is needed:

git clone https://github.com/castorini/Anserini-data.git

First, build the various indexes, as follows.

Indexing

Index of ClueWeb12:

nohup sh Anserini/target/appassembler/bin/IndexCollection -collection ClueWeb12Collection \
 -generator JsoupGenerator -threads 44 -input /path/to/cw12 -index lucene-index.cw12.pos+docvectors+rawdocs \
 -storePositions -storeDocvectors -storeRawDocs >& log.cw12.pos+docvectors+rawdocs &

Index of CW12Lite2013:

(Option 1): If you already have the ClubWeb12 full index (above) with -storeRawDocs option enabled when indexing:

nohup Anserini/target/appassembler/bin/IndexUtils -index lucene-index.cw12.pos+docvectors+rawdocs \
 -dumpRawDocs Anserini-data/TREC2018/CENTRE/task2/cw12lite2013_docids &

This will generate a file about 19GB in raw size.

nohup Anserini/target/appassembler/bin/IndexCollection -collection HtmlCollection \
 -input cw12lite2013_docids_rawdocs.dump -index lucene-index.cw12lite2013.pos+docvectors+rawdocs \
 -generator JsoupGenerator -threads 44 -storePositions -storeDocvectors -storeRawDocs -optimize \
 >& log.cw12lite2013.pos+docvectors+rawdocs &

This will generate an index about 8.3GB in size.

(Option 2): If you would like to build the index from scratch (e.g. you do not have ClueWeb12 full index):

nohup sh Anserini/target/appassembler/bin/IndexCollection -collection ClueWeb12Collection \
 -generator JsoupGenerator -threads 44 -input /path/to/cw12 -index \
 lucene-index.cw12lite2013.pos+docvectors+rawdocs -storePositions -storeDocvectors -storeRawDocs \
 -whitelist Anserini-data/TREC2018/CENTRE/task2/cw12lite2013_docids >& log.cw12lite2013.pos+docvectors+rawdocs &

Index of CW12Lite2018:

(Option 1): If you already have the ClubWeb12 Full index with -storeRawDocs option enabled when indexing:

nohup Anserini/target/appassembler/bin/IndexUtils -index lucene-index.cw12.pos+docvectors+rawdocs \
 -dumpRawDocs Anserini-data/TREC2018/CENTRE/task2/cw12lite2018_docids &

This will gnereate a file about 28GB in raw size.

nohup Anserini/target/appassembler/bin/IndexCollection -collection HtmlCollection \
 -input cw12lite2018_docids_rawdocs.dump -index lucene-index.cw12lite2018.pos+docvectors+rawdocs \
 -generator JsoupGenerator -threads 44 -storePositions -storeDocvectors -storeRawDocs \
 -optimize >& log.cw12lite2018.pos+docvectors+rawdocs &

This will generate an index about 12GB in size.

(Option 2): If you would like to build the index from scratch (e.g. you do not have clueweb12 full index):

nohup sh Anserini/target/appassembler/bin/IndexCollection -collection ClueWeb12Collection \
 -generator JsoupGenerator -threads 44 -input /path/to/cw12 -index \
 lucene-index.cw12lite2018.pos+docvectors+rawdocs -storePositions -storeDocvectors -storeRawDocs \
 -whitelist Anserini-data/TREC2018/CENTRE/task2/cw12lite2013_docids >& log.cw12lite2018.pos+docvectors+rawdocs &

Index of snippets 2013

nohup sh Anserini/target/appassembler/bin/IndexCollection -input \
 Anserini-data/TREC2018/CENTRE/task2/searchengine_snippets/snippets2013_anserini/ \
 -collection JsonCollection -index lucene-index.snippets2013.pos+docvectors+rawdocs \
 -generator JsoupGenerator -threads 8 -uniqueDocid -storePositions -storeDocvectors \
 -storeRawDocs -optimize >& log.snippets2013.pos+docvectors+rawdocs &

Index of snippets 2018

nohup sh Anserini/target/appassembler/bin/IndexCollection -input \
    Anserini-data/TREC2018/CENTRE/task2/searchengine_snippets/snippets2018_anserini/ \
    -collection JsonCollection -index lucene-index.snippets2018.pos+docvectors+rawdocs \
    -generator JsoupGenerator -threads 8 -uniqueDocid -storePositions -storeDocvectors \
    -storeRawDocs -optimize >& log.snippets2018.pos+docvectors+rawdocs &

Index of Wikipedia dump (optional):

curl -O https://dumps.wikimedia.org/enwiki/20180620/enwiki-20180620-pages-articles.xml.bz2

For verification, md5 bca0ceb72e000105cc97fb54fef70cc3

nohup sh Anserini/target/appassembler/bin/IndexCollection -collection WikipediaCollection \
-generator JsoupGenerator -threads 16 -input enwiki-20180620-pages-articles.xml.bz2 -index \
lucene-index.wiki.pos+docvectors -storePositions -storeDocvectors >& log.wiki.pos+docvectors &

NOTE: Topics and qrels are currently available only to TREC 2018 participants. Users will need to download the topics and qrels directly from the NIST website and put them at src/main/resources/topics-and-qrels/qrels.web.201-250.new.pruned.txt. These files will be checked into the repo after NIST publishes them publicly.
