# Anserini Regressions: ClueWeb12

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

This page describes regressions for the Web Tracks from TREC 2013 and 2014 using the (full) [ClueWeb12 collection](http://lemurproject.org/clueweb12.php/).
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/cw12/` should be the root directory of the (full) [ClueWeb12 collection](http://lemurproject.org/clueweb12.php/), i.e., `/path/to/cw12/` should contain `Disk1`, `Disk2`, `Disk3`, `Disk4`.

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.web.201-250.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/topics.web.201-250.txt): [topics for the TREC 2013 Web Track (Topics 201-250)](http://trec.nist.gov/data/web/2013/trec2013-topics.xml)
+ [`topics.web.251-300.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/topics.web.251-300.txt): [topics for the TREC 2014 Web Track (Topics 251-300)](http://trec.nist.gov/data/web/2014/trec2014-topics.xml)
+ [`qrels.web.201-250.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/qrels.web.201-250.txt): [one aspect per topic qrels for the TREC 2013 Web Track (Topics 201-250)](http://trec.nist.gov/data/web/2013/qrels.adhoc.txt)
+ [`qrels.web.251-300.txt`](https://github.com/castorini/anserini-tools/tree/master/topics-and-qrels/qrels.web.251-300.txt): [one aspect per topic qrels for the TREC 2014 Web Track (Topics 251-300)](http://trec.nist.gov/data/web/2014/qrels.adhoc.txt)

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

```
${ranking_cmds}
```

Evaluation can be performed using `trec_eval` and `gdeval.pl`:

```
${eval_cmds}
```

## Effectiveness

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