# Anserini Regressions: QA on Wikipedia 100-word splits

**Models**: BM25

This page documents QA regression experiments on the `wikipedia-dpr-100w` corpus, which is integrated into Anserini's regression testing framework.

The exact configurations for these regressions are stored in [this YAML file](${yaml}).
Note that this page is automatically generated from [this template](${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:

```bash
python src/main/python/run_regression.py --index --verify --search --regression ${test_name}
```

## Indexing

Typical indexing command:

```bash
${index_cmds}
```

The directory `/path/to/${corpus}/`should be a directory containing the wikipedia-dpr-100w passages collection retrieved from [here](https://dl.fbaipublicfiles.com/dpr/wikipedia_split/psgs_w100.tsv.gz).

For additional details, see explanation of [common indexing options](${root_path}/docs/common-indexing-options.md).

## Retrieval

Topics and qrels are stored [here](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels), which is linked to the Anserini repo as a submodule.
The regression experiments here evaluate on the test sets of Natural Questions, TriviaQA, SQuAD, and WebQuestions.

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

```bash
${ranking_cmds}
```

The trec format will need to be converted to DPR's JSON format for evaluation:
```bash
${converting_cmds}
```

Evaluation can be performed using scripts from pyserini:

```bash
${eval_cmds}
```

## Effectiveness

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

${effectiveness}
