+The model should be used giving as input a short paragraph of text taken from a news programme or article in Italian
 about which it is requested to get an answer about whether or not it contains a change of topic.
+The model has been trained to detect topic changes without apriori knowledge of possible points of separation (e.g., paragraphs or speaker turns). 
+For this reason it tends to be sensitive to the amount of text supposed to belong to either of the two subsequent topics, and therefore performs better when
+the sought for topic change occurs approximately in the middle of the input. To reduce the impact of this issue, it is suggested to use
+the model on a sequence of partially overlapping pieces of text taken from the document to be analysed, and to further process the results sequence
+to consolidate a decision.
