# topic_immigration_it

This is a [BERTopic](https://github.com/MaartenGr/BERTopic) model built as part of the European project [VALAWAI](https://valawai.eu) and designed for predicting the topic distribution of immigration-related content in Italian language.<br>
The model includes a pointer towards the model to be loaded in with SentenceTransformers, i.e., "sentence-transformers/paraphrase-multilingual-mpnet-base-v2".<br>
The model was fine-tuned on a comprehensive set of tweets representing the information provided by both political entities and news sources on the immigration subject during the 5-year period 2018-2022. 

## Usage 

To use this model, please install BERTopic:

```
pip install -U bertopic
```

You can use the model as follows:

```python
from bertopic import BERTopic
topic_model = BERTopic.load("brema76/topic_immigration_it")

topic_model.get_topic_info()

example_text = "Questo è un esempio di testo sul topic immigrazione, subtopic sbarchi e accoglienza."
topics, probs = topic_model.transform(example_text)

probs = probs / probs.sum()
```
