# Script Fidelity Rate

This directory is the Hugging Face Evaluate metric module for Script Fidelity
Rate (SFR).

The Python package is published as `script-fidelity` on PyPI:
<https://pypi.org/project/script-fidelity/>. The import name is
`script_fidelity`.

```python
import evaluate

sfr = evaluate.load("./metrics/script_fidelity_rate", module_type="metric")
result = sfr.compute(
    predictions=["کابل کې ښه هوا ده", "this is romanized output"],
    language="ps_af",
)
print(result["sfr_percent"])
```

Hub use:

```python
import evaluate

sfr = evaluate.load("themechanism/script_fidelity_rate", module_type="metric")
sfr.compute(predictions=["کابل کې ښه هوا ده"], language="pashto")
```

Use SFR with WER and CER, not instead of them. SFR checks whether output is in
the intended script. It does not measure lexical accuracy.
