1. Variables and notations
| Term | Meaning | Variable in script | Scripts |
|---|---|---|---|
| collection | name of the collection/dataset (biocaddie, ohsumed, treccds, trecgenomics) | col | all |
| subset | set of data used for running baselines (combined, test, train) | subset | all |
| topics | name of the topics file (short, orig, stopped, etc) | topics | all |
| year | year of the collection/dataset, available for few collections such as trecgenomics (2006, 2007) | year | all |
| model | retrieval model (dir, rm3, jm, pubmed, etc) | model | mkeval.sh, mkeval-lucene.sh |
| from model | retrieval model (dir, rm3, jm, pubmed, etc), for comparison (t-test) | from | compare.R |
| to model | retrieval model (dir, rm3, jm, pubmed, etc), for comparison (t-test) | to | compare.R |
| metric | evaluation metric (map, ndcg, P_20, ndcg_cut_20, etc) | metric | mkeval.sh, mkeval-lucene.sh, compare.R |
| run method | running method (indri, lucene) | run | compare.R |
2. Files and their locations
Collections without year: biocaddie, ohsumed

*** Note: both Lucene and Indri's loocv results are saved in the same location for easy comparison across different runs.
3. Run Lucene baselines
a) Lucene Run (lucene-output)
cd ~/biocaddie
baselines/new/<model>-lucene.sh <topics> <subset> <col>| parallel -j 20 bash -c "{}"
baselines/new/<model>-lucene.sh <topics> <subset> <col> <year>| parallel -j 20 bash -c "{}"
Eg: baselines/new/dir-lucene.sh short test biocaddie | parallel -j 20 bash -c "{}"
b) Evaluation and Cross-validation (lucene-eval, loocv)
cd ~/biocaddie scripts/new/mkeval-lucene.sh <model> <topics> <subset> <col> scripts/new/mkeval-lucene.sh <model> <topics> <subset> <col> <year>
Eg: scripts/new/mkeval-lucene.sh dir short test biocaddie
c) Compare models
We have to input running method for comparison:
0 - both from and to models are from Indri run
1 - both from and to models are from Lucene run
2 - from model is from Indri run, to model is from Lucene run
3 - from model is from Lucene run, to model is from Indri run
cd ~/biocaddie Rscript scripts/new/compare.R <subset> <from> <to> <topics> <col> Rscript scripts/new/compare.R <subset> <from> <to> <topics> <col> <year>
Eg: Rscript scripts/new/compare.R test tfidf dir short biocaddie
