# Czech email urgency classifier

Local three-class text classifier:

- `not_urgent` — nenaléhavý
- `urgent` — naléhavý
- `very_urgent` — velmi naléhavý

Double-click `Spustit klasifikator.bat`, enter an optional subject, paste the email body,
and type `/odeslat` on a separate line. Type `/konec` to exit.

The model uses word and character TF-IDF features with balanced multinomial logistic
regression. Inference is entirely local and does not send email text to an API or server.

`email_urgency_model.joblib` must only be loaded from this trusted package. Joblib uses
Python pickle internally and untrusted model files may execute code when loaded.

Reported metrics are measured on synthetic held-out data and are not evidence of accuracy
on real company email. Validate with manually labelled, anonymised real messages before
using the classifier for operational decisions.
