Anserini Regressions: CIRAL (v1.0) — Somali

This page documents BM25 monolingual regression experiments on the dev set of CIRAL (v1.0) — Somali.

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 ciral-v1.0-so

Indexing

Typical indexing command:

target/appassembler/bin/IndexCollection \
  -collection MrTyDiCollection \
  -input /path/to/ciral-somali \
  -index indexes/lucene-index.ciral-v1.0-so/ \
  -generator DefaultLuceneDocumentGenerator \
  -threads 16 -storePositions -storeDocvectors -storeRaw -language so \
  >& logs/log.ciral-somali &

See this page for more details about the CIRAL corpus. For additional details, see explanation of common indexing options.

Retrieval

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

target/appassembler/bin/SearchCollection \
  -index indexes/lucene-index.ciral-v1.0-so/ \
  -topics tools/topics-and-qrels/topics.ciral-v1.0-so-dev-native.tsv \
  -topicreader TsvInt \
  -output runs/run.ciral-somali.bm25-default.topics.ciral-v1.0-so-dev-native.txt \
  -bm25 -hits 1000 -language so &

Evaluation can be performed using trec_eval:

tools/eval/trec_eval.9.0.4/trec_eval -c -m ndcg_cut.20 tools/topics-and-qrels/qrels.ciral-v1.0-so-dev.tsv runs/run.ciral-somali.bm25-default.topics.ciral-v1.0-so-dev-native.txt
tools/eval/trec_eval.9.0.4/trec_eval -c -M 10 -m recip_rank tools/topics-and-qrels/qrels.ciral-v1.0-so-dev.tsv runs/run.ciral-somali.bm25-default.topics.ciral-v1.0-so-dev-native.txt
tools/eval/trec_eval.9.0.4/trec_eval -c -m recall.100 tools/topics-and-qrels/qrels.ciral-v1.0-so-dev.tsv runs/run.ciral-somali.bm25-default.topics.ciral-v1.0-so-dev-native.txt

Effectiveness

With the above commands, you should be able to reproduce the following results:

nDCG@20 BM25 (default)
CIRAL Somali: Dev 0.1500
MRR@10 BM25 (default)
CIRAL Somali: Dev 0.4000
R@100 BM25 (default)
CIRAL Somali: Dev 0.1850
