| # Pyserini: Performance Comparison of Python versus Java RM3 and Rocchio Implementations | ||
|
|
||
| We fully re-implmented the RM3 and Rocchio implementations from Anserini in Python. Below is a comparison of the performance of RM3 and Rocchio in Python versus in Java. | ||

There was a problem hiding this comment. Add a date somewhere, these experiments were from... |
||
|
|
||
| For example, to run RM3 in Python over TREC DL21, | ||
|
|
||
| ``` | ||
| python -m pyserini.search.lucene \ | ||
| --threads 16 --batch-size 128 \ | ||
| --index msmarco-v2-passage \ | ||
| --topics dl21 \ | ||
| --output run.msmarco-v2-passage.bm25-rm3-default.dl21.txt \ | ||
| --bm25 --rm3-py | ||
| ``` | ||
|
|
||
| Rocchio follows similar style: | ||
|
|
||
| ``` | ||
| python -m pyserini.search.lucene \ | ||
| --threads 16 --batch-size 128 \ | ||
| --index msmarco-v2-passage \ | ||
| --topics dl21 \ | ||
| --output run.msmarco-v2-passage.bm25-rm3-default.dl21.txt \ | ||
| --bm25 --rocchio-py | ||
| ``` | ||
|
|
||
| ## Performance Comparison | ||
|
|
||
| For this experiment, there were the computer specs: | ||
|
|
||
| - OS: Windows 11 (x64), WSL | ||
| - Machine: Intel NUC11PHi7 | ||
| - CPU: 11th Gen Intel Core i7 | ||
| - RAM: 16 GB | ||
