Anserini Regressions: Tweets2011 (MB11 & MB12)

Models: various bag-of-words approaches

This page describes regressions for the Microblog Tracks from TREC 2011 and 2012 using the Tweets2011 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 mb11

Indexing

Note that the Tweets2011 collection is distributed as a list of tweet ids that you have to download yourself, so the effectiveness results you'll get should be similar, but will likely not be identical to the scores reported here.

Indexing the Tweets2011 collection:

bin/run.sh io.anserini.index.IndexCollection \
  -threads 44 \
  -collection TweetCollection \
  -input /path/to/mb11 \
  -generator TweetGenerator \
  -index indexes/lucene-index.mb11/ \
  -storePositions -storeDocvectors -storeRaw -tweet.keepUrls -tweet.stemming \
  >& logs/log.mb11 &

More available indexing options:

  • -tweet.keepRetweets: boolean switch to keep retweets while indexing, default false
  • -tweet.keepUrls: boolean switch to keep URLs in the tweet, default false
  • -tweet.stemming: boolean switch to apply Porter stemming while indexing tweets, default false
  • -tweet.maxId: the max tweet Id for indexing. Tweet Ids that are larger (when being parsed to Long type) than this value will NOT be indexed, default LONG.MAX_VALUE
  • -tweet.deletedIdsFile: a file that contains deleted tweetIds, one per line. these tweeets won't be indexed

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:

bin/run.sh io.anserini.search.SearchCollection \
