# Anserini Regressions: TREC Disks 4 & 5

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

This page describes regressions for ad hoc topics from TREC 7-8, which use [TREC Disks 4 & 5](https://trec.nist.gov/data/cd45/index.html).
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/disk45/` should be the root directory of [TREC Disks 4 & 5](https://trec.nist.gov/data/cd45/index.html); inside each there should be subdirectories like `ft`, `fr94`.
Note that Anserini ignores the `cr` folder when indexing, which is the standard configuration.

For additional details, see explanation of [common indexing options](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.
They are downloaded from NIST:

+ [`topics.adhoc.351-400.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/topics.adhoc.351-400.txt): [TREC-7 Ad Hoc Topics 351-400](http://trec.nist.gov/data/topics_eng/)
+ [`topics.adhoc.401-450.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/topics.adhoc.401-450.txt): [TREC-8 Ad Hoc Topics 401-450](http://trec.nist.gov/data/topics_eng/)
+ [`qrels.adhoc.351-400.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/qrels.adhoc.351-400.txt): [qrels for TREC-7 Ad Hoc Topics 351-400](http://trec.nist.gov/data/qrels_eng/)
+ [`qrels.adhoc.401-450.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/qrels.adhoc.401-450.txt): [qrels for TREC-8 Ad Hoc Topics 401-450](http://trec.nist.gov/data/qrels_eng/)

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:
