+## Potential weakness of the model
+
+* As the model has been trained on data of short length, it is difficult to predict how the model will behave on long texts
+* Although the model is robust to typos and able to generate synonyms, the entities and topics must be as explicit as possible. 
+* The model may have difficulties to detect very abstract and complex topics, a fine tuning of the model can solve this problem
+* The model may have difficulty in capturing elements that are very specific to a given context
