# Anserini Regressions: Gov2

**Models**: various bag-of-words approaches

This page describes regressions for the Terabyte Tracks from TREC 2004 to 2006, which uses the [Gov2 collection](http://ir.dcs.gla.ac.uk/test_collections/gov2-summary.htm).
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:

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

## Indexing

Typical indexing command:

```
${index_cmds}
```

The directory `/path/to/gov2/` should be the root directory of the [Gov2 collection](http://ir.dcs.gla.ac.uk/test_collections/gov2-summary.htm), i.e., `ls /path/to/gov2/` should bring up a bunch of subdirectories, `GX000` to `GX272`.

For additional details, see explanation of [common indexing options](common-indexing-options.md).

## Retrieval

Topics and qrels are stored in [`src/main/resources/topics-and-qrels/`](../src/main/resources/topics-and-qrels/), downloaded from NIST:

+ [`topics.terabyte04.701-750.txt`](../src/main/resources/topics-and-qrels/topics.terabyte04.701-750.txt): [topics for the TREC 2004 Terabyte Track (Topics 701-750)](http://trec.nist.gov/data/terabyte/04/04topics.701-750.txt)
+ [`topics.terabyte05.751-800.txt`](../src/main/resources/topics-and-qrels/topics.terabyte05.751-800.txt): [topics for the TREC 2005 Terabyte Track (Topics 751-800)](http://trec.nist.gov/data/terabyte/05/05.topics.751-800.txt)
+ [`topics.terabyte06.801-850.txt`](../src/main/resources/topics-and-qrels/topics.terabyte06.801-850.txt): [topics for the TREC 2006 Terabyte Track (Topics 801-850)](http://trec.nist.gov/data/terabyte/06/06.topics.801-850.txt)

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

```
${ranking_cmds}
```

Evaluation can be performed using `trec_eval`:

```
${eval_cmds}
```

## Effectiveness

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