Dobbiamo dare una prospettiva di rinascita a tutti gli italiani, dall'opposizione ancora all'attacco del governo, gli italiani sono esausti di fare sacrifici che non portano a nulla. Sono quattro le persone indagate dalla Procura di Roma per le minacce via mail al ministro della Salute. Tra ottobre del 2020 e il gennaio del 2021 avrebbero inviato al ministro dei messaggi dal contenuto gravemente minaccioso. Al ministro la solidarietà di tutto il mondo politico e a causa della pandemia si assottigliano i redditi delle famiglie italiane. Aumenta anche la pressione fiscale. Lo rileva l'Istat."

La lotta al virus e anche lotta alle fake news, prosegue la collaborazione tra ministero della Salute e Twitter quando si cercano notizie sul Covid del Social rimanda le pagine del ministero, includendo anche le ultime informazioni sui vaccini. COVID-19 è stato l'hashtag più twittato a livello globale nel 2020. La poltrona negata da Erdogan ad Ursula von der Leyen, lo avete sentito? Fa ancora discutere dentro e fuori dal Parlamento europeo: Marco Clementi. "

# Model Card for raicrits/topicChangeDetector_v1

<!-- Provide a quick summary of what the model is/does. -->

This model analyses the input text and provides an answer whether in the text there is a change of topic or not (resp. TOPPICCHANGE, SAMETOPIC).

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->



- **Developed by:** Alberto Messina (alberto.messina@rai.it)
- **Model type:** BERT for Sequence Classification
- **Language(s) (NLP):** Italian
- **License:** TBD
- **Finetuned from model:** https://huggingface.co/xlm-roberta-base

### Model Sources [optional]

<!-- Provide the basic links for the model. -->

- **Repository:** N/A
- **Paper [optional]:** N/A
- **Demo [optional]:** N/A

## Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
The model should be used giving a short paragraph of text in Italian as input 
about which it is requested to get an answer about whether or not it contains a change of topic.

### Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->

TBA

### Out-of-Scope Use

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

The model should not be used as a general purpose topic change detector, i.e. on text which is not originated from news programme transcription or siilar content.


## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->

The training dataset is made up of automatic transcriptions from RAI Italian newscasts, therefore there is an intrinsic bias in the kind
of topics that can be tracked for change.

## How to Get Started with the Model
