Anserini: Experiments on AQUAINT (Robust05)

Indexing

Typical indexing command:

nohup sh target/appassembler/bin/IndexCollection -collection TrecCollection \
-generator JsoupGenerator -threads 16 -input /path/to/robust05 -index \
lucene-index.robust05.pos+docvectors+rawdocs -storePositions -storeDocvectors \
-storeRawDocs >& log.robust05.pos+docvectors+rawdocs &

The directory /path/to/aquaint/ should be the root directory of AQUAINT collection; under subdirectory disk1/ there should be NYT/ and under subdirectory disk2/ there should be APW/ and XIE/.

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 -topicreader Trec -index lucene-index.robust05.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.robust05.txt -output run.robust05.bm25.topics.robust05.txt -bm25 &

nohup target/appassembler/bin/SearchCollection -topicreader Trec -index lucene-index.robust05.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.robust05.txt -output run.robust05.bm25+rm3.topics.robust05.txt -bm25 -rm3 &

nohup target/appassembler/bin/SearchCollection -topicreader Trec -index lucene-index.robust05.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.robust05.txt -output run.robust05.bm25+ax.topics.robust05.txt -bm25 -axiom -rerankCutoff 20 -axiom.deterministic &

nohup target/appassembler/bin/SearchCollection -topicreader Trec -index lucene-index.robust05.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.robust05.txt -output run.robust05.ql.topics.robust05.txt -ql &

nohup target/appassembler/bin/SearchCollection -topicreader Trec -index lucene-index.robust05.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.robust05.txt -output run.robust05.ql+rm3.topics.robust05.txt -ql -rm3 &

nohup target/appassembler/bin/SearchCollection -topicreader Trec -index lucene-index.robust05.pos+docvectors+rawdocs -topics src/main/resources/topics-and-qrels/topics.robust05.txt -output run.robust05.ql+ax.topics.robust05.txt -ql -axiom -rerankCutoff 20 -axiom.deterministic &

Evaluation can be performed using trec_eval:

eval/trec_eval.9.0.4/trec_eval -m map -m P.30 src/main/resources/topics-and-qrels/qrels.robust2005.txt run.robust05.bm25.topics.robust05.txt

eval/trec_eval.9.0.4/trec_eval -m map -m P.30 src/main/resources/topics-and-qrels/qrels.robust2005.txt run.robust05.bm25+rm3.topics.robust05.txt

eval/trec_eval.9.0.4/trec_eval -m map -m P.30 src/main/resources/topics-and-qrels/qrels.robust2005.txt run.robust05.bm25+ax.topics.robust05.txt

eval/trec_eval.9.0.4/trec_eval -m map -m P.30 src/main/resources/topics-and-qrels/qrels.robust2005.txt run.robust05.ql.topics.robust05.txt

eval/trec_eval.9.0.4/trec_eval -m map -m P.30 src/main/resources/topics-and-qrels/qrels.robust2005.txt run.robust05.ql+rm3.topics.robust05.txt

eval/trec_eval.9.0.4/trec_eval -m map -m P.30 src/main/resources/topics-and-qrels/qrels.robust2005.txt run.robust05.ql+ax.topics.robust05.txt

Effectiveness

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

MAP BM25 BM25+RM3 BM25+AX QL QL+RM3 QL+AX
All Topics 0.2031 0.2602 0.2584 0.2028 0.2491 0.2476
P30 BM25 BM25+RM3 BM25+AX QL QL+RM3 QL+AX
All Topics 0.3693 0.4187 0.4120 0.3653 0.4067 0.4113
You can’t perform that action at this time.
