 **I**talian-**S**entence **P**air **In**ference, AKA **I-SPIn**.<br>
 This is a fine-tuned version of the model [paraphrase-multilingual-mpnet-base-v2](https://huggingface.co/sentence-transformers/paraphrase-multilingual-mpnet-base-v2).<br>
 Its main task is to perform the [Natural Language Inference (NLI)](https://nlp.stanford.edu/projects/snli/) task in the Italian language.<br>
-The prediction label has two possible values: 1 means the model predicts <em>entailment</em>, 0 represents the <em>neutral</em> case
- while -1 corresponds to <em>contradiction</em>.
+The prediction labels may assume three possible values: 
+1. 1 means the model predicts <em>entailment</em>;
+2. 0 represents the <em>neutral</em> case;
+3. -1 corresponds to <em>contradiction</em>.
