# About

This is a GLiNER model finetuned on medieval Latin. It was trained to improve the identification of PERSON and LOC. It was finetuned from [urchade/gliner_multi-v2.1](https://huggingface.co/urchade/gliner_multi-v2.1). The model was finetuned on 1,500 annotations from the [Home Alcar sentences](https://huggingface.co/datasets/medieval-data/medieval-latin-ner-HOME-Alcar-sents). Only 1,500 were selected to prevent catastrophic forgetting.

GLiNER is a Named Entity Recognition (NER) model capable of identifying any entity type using a bidirectional transformer encoder (BERT-like). It provides a practical alternative to traditional NER models, which are limited to predefined entities, and Large Language Models (LLMs) that, despite their flexibility, are costly and large for resource-constrained scenarios.

## Installation
To use this model, you must install the GLiNER Python library:
```
!pip install gliner
```

## Usage
Once you've downloaded the GLiNER library, you can import the GLiNER class. You can then load this model using `GLiNER.from_pretrained` and predict entities with `predict_entities`.

```python
from gliner import GLiNER

model = GLiNER.from_pretrained("medieval-data/gliner_multi-v2.1-medieval-latin")

text = """
Testes : magister Stephanus cantor Autissiodorensis , Petrus capellanus comitis , Gaufridus clericus , Hugo de Argenteolo , Milo Filluns , Johannes Maleherbe , Nivardus de Argenteolo , Columbus tunc prepositus Tornodorensis , Johannes prepositus Autissiodorensis , Johannes Brisebarra .
"""

labels = ["PERSON", "LOC"]

entities = model.predict_entities(text, labels)

for entity in entities:
    print(entity["text"], "=>", entity["label"])
```

```
Stephanus => PERSON
Autissiodorensis => LOC
Petrus => PERSON
Gaufridus => PERSON
Hugo de Argenteolo => PERSON
Milo Filluns => PERSON
Johannes Maleherbe => PERSON
Nivardus de Argenteolo => PERSON
Columbus => PERSON
Tornodorensis => LOC
Johannes => PERSON
Autissiodorensis => LOC
Johannes Brisebarra => PERSON
```
