Jury

A comprehensive toolkit for evaluating NLP experiments offering various automated metrics. Jury offers a smooth and easy-to-use interface. It uses a more advanced version of evaluate design for underlying metric computation, so that adding custom metric is easy as extending proper class.

Main advantages that Jury offers are:

• Easy to use for any NLP project.
• Unified structure for computation input across all metrics.
• Calculate many metrics at once.
• Metrics calculations can be handled concurrently to save processing time.
• It seamlessly supports evaluation for multiple predictions/multiple references.

Available Metrics

The table below shows the current support status for available metrics.

| Metric | Jury Support | HF/evaluate Support | |-------------------------------------------------------------------------------|--------------------|---------------------| | Accuracy-Numeric | :heavycheckmark: | :whitecheckmark: | | Accuracy-Text | :heavycheckmark: | :x: | | Bartscore | :heavycheckmark: | :x: | | Bertscore | :heavycheckmark: | :whitecheckmark: | | Bleu | :heavycheckmark: | :whitecheckmark: | | Bleurt | :heavycheckmark: | :whitecheckmark: | | CER | :heavycheckmark: | :whitecheckmark: | | CHRF | :heavycheckmark: | :whitecheckmark: | | COMET | :heavycheckmark: | :whitecheckmark: | | F1-Numeric | :heavycheckmark: | :whitecheckmark: | | F1-Text | :heavycheckmark: | :x: | | METEOR | :heavycheckmark: | :whitecheckmark: | | Precision-Numeric | :heavycheckmark: | :whitecheckmark: | | Precision-Text | :heavycheckmark: | :x: | | Prism | :heavycheckmark: | :x: | | Recall-Numeric | :heavycheckmark: | :whitecheckmark: | | Recall-Text | :heavycheckmark: | :x: | | ROUGE | :heavycheckmark: | :whitecheckmark: | | SacreBleu | :heavycheckmark: | :whitecheckmark: | | Seqeval | :heavycheckmark: | :whitecheckmark: | | Squad | :heavycheckmark: | :whitecheckmark: | | TER | :heavycheckmark: | :whitecheckmark: | | WER | :heavycheckmark: | :whitecheckmark: | | Other metrics* | :whitecheckmark: | :whitecheckmark: |

* Placeholder for the rest of the metrics available in evaluate package apart from those which are present in the table.

Notes

• The entry :heavycheckmark: represents that full Jury support is available meaning that all combinations of input types (single prediction & single reference, single prediction & multiple references, multiple predictions & multiple references) are supported

• The entry :whitecheckmark: means that this metric is supported (for Jury through the evaluate), so that it can (and should) be used just like the evaluate metric as instructed in evaluate implementation although unfortunately full Jury support for those metrics are not yet available.

Request for a New Metric

For the request of a new metric please open an issue providing the minimum information. Also, PRs addressing new metric supports are welcomed :).

Installation

Through pip,

pip install jury

or build from source,

git clone https://github.com/obss/jury.git
cd jury
python setup.py install

NOTE: There may be malfunctions of some metrics depending on sacrebleu package on Windows machines which is mainly due to the package pywin32. For this, we fixed pywin32 version on our setup config for Windows platforms. However, if pywin32 causes trouble in your environment we strongly recommend using conda manager install the package as conda install pywin32.

Usage

API Usage

It is only two lines of code to evaluate generated outputs.

```python from jury import Jury

scorer = Jury() predictions = [ ["the cat is on the mat", "There is cat playing on the mat"], ["Look! a wonderful day."] ] references = [ ["the cat is playing on the mat.", "The cat plays on the mat."], ["Today is a wonderful day", "The weather outside is wonderful."] ] scores = scorer(predictions=predictions, references=references) ```

Specify metrics you want to use on instantiation.

python scorer = Jury(metrics=["bleu", "meteor"]) scores = scorer(predictions, references)

Use of Metrics standalone

You can directly import metrics from jury.metrics as classes, and then instantiate and use as desired.

```python from jury.metrics import Bleu

bleu = Bleu.construct() score = bleu.compute(predictions=predictions, references=references) ```

The additional parameters can either be specified on compute()

```python from jury.metrics import Bleu

bleu = Bleu.construct() score = bleu.compute(predictions=predictions, references=references, max_order=4) ```

, or alternatively on instantiation

python from jury.metrics import Bleu bleu = Bleu.construct(compute_kwargs={"max_order": 1}) score = bleu.compute(predictions=predictions, references=references)

Note that you can seemlessly access both jury and evaluate metrics through jury.load_metric.

```python import jury

bleu = jury.loadmetric("bleu") bleu1 = jury.loadmetric("bleu", resultingname="bleu1", computekwargs={"max_order": 1})

metrics not available in jury but in evaluate

wer = jury.loadmetric("competitionmath") # It falls back to evaluate package with a warning ```

CLI Usage

You can specify predictions file and references file paths and get the resulting scores. Each line should be paired in both files. You can optionally provide reduce function and an export path for results to be written.

jury eval --predictions /path/to/predictions.txt --references /path/to/references.txt --reduce_fn max --export /path/to/export.txt

You can also provide prediction folders and reference folders to evaluate multiple experiments. In this set up, however, it is required that the prediction and references files you need to evaluate as a pair have the same file name. These common names are paired together for prediction and reference.

jury eval --predictions /path/to/predictions_folder --references /path/to/references_folder --reduce_fn max --export /path/to/export.txt

If you want to specify metrics, and do not want to use default, specify it in config file (json) in metrics key.

json { "predictions": "/path/to/predictions.txt", "references": "/path/to/references.txt", "reduce_fn": "max", "metrics": [ "bleu", "meteor" ] }

Then, you can call jury eval with config argument.

jury eval --config path/to/config.json

Custom Metrics

You can use custom metrics with inheriting jury.metrics.Metric, you can see current metrics implemented on Jury from jury/metrics. Jury falls back to evaluate implementation of metrics for the ones that are currently not supported by Jury, you can see the metrics available for evaluate on evaluate/metrics.

Jury itself uses evaluate.Metric as a base class to drive its own base class as jury.metrics.Metric. The interface is similar; however, Jury makes the metrics to take a unified input type by handling the inputs for each metrics, and allows supporting several input types as;

• single prediction & single reference
• single prediction & multiple reference
• multiple prediction & multiple reference

As a custom metric both base classes can be used; however, we strongly recommend using jury.metrics.Metric as it has several advantages such as supporting computations for the input types above or unifying the type of the input.

```python from jury.metrics import MetricForTask

class CustomMetric(MetricForTask): def computesinglepredsingleref( self, predictions, references, reducefn = None, **kwargs ): raise NotImplementedError

def _compute_single_pred_multi_ref(
    self, predictions, references, reduce_fn = None, **kwargs
):
    raise NotImplementedError

def _compute_multi_pred_multi_ref(
        self, predictions, references, reduce_fn = None, **kwargs
):
    raise NotImplementedError

```

For more details, have a look at base metric implementation jury.metrics.Metric

PRs are welcomed as always :)

Installation

git clone https://github.com/obss/jury.git
cd jury
pip install -e ".[dev]"

Also, you need to install the packages which are available through a git source separately with the following command. For the folks who are curious about "why?"; a short explaination is that PYPI does not allow indexing a package which are directly dependent on non-pypi packages due to security reasons. The file requirements-dev.txt includes packages which are currently only available through a git source, or they are PYPI packages with no recent release or incompatible with Jury, so that they are added as git sources or pointing to specific commits.

pip install -r requirements-dev.txt
