 ## Model Description
 ConPGS Model is capable of generating paraphrases while controlling for semantic and lexical similarity.  
-The semantic similarity can be controlled at six levels - 70, 75, 80, 85, 90 and 95 - the higher the level, the more similar the model outputs sentences with similar meanings.  
-The lexical similarity can be controlled in eight steps 5, 10, 15, 20, 25, 30, 35 and 40, the higher the level, the more the model outputs sentences with similar surfaces.
+The semantic similarity can be controlled at six levels - 70, 75, 80, 85, 90 and 95 - the higher the level, the more similar the model outputs sentences with similar meanings.　This value is expressed as sim.  
+The lexical similarity can be controlled in eight steps 5, 10, 15, 20, 25, 30, 35 and 40, the higher the level, the more the model outputs sentences with similar surfaces.　This value is expressed as bleu.
 
 This model was constructed by fine-tuning [BART-large](https://huggingface.co/facebook/bart-large).
