+# Adjective Synonym Substitution 🦎  + ⌨️ → 🐍
+
+
+This transformation change some words with synonyms according to if their POS tag is a ADJ for simple french sentences. It requires Spacy_lefff (an extention of spacy for french POS and lemmatizing) and nltk package with the open multilingual wordnet dictionary.
+
+Authors : Lisa Barthe and Louanes Hamla from Fablab by Inetum in Paris
+
+## What type of transformation it is ?
+This transformation allows to create paraphrases with a different word in french. The general meaning of the sentence remains but it can be declined on different paraphrases with one adjective variation.
+
+## Supported Task
+
+This perturbation can be used for any French task.
+
+## What does it intend to benefit ?
+
+This perturbation would benefit all tasks which have a sentence/paragraph/document as input like text classification, text generation, etc. that requires synthetic data augmentation / diversification.
+
+## What are the limitation of this transformation ?
+This tool does not take the general context into account, sometimes, the ouput will not match the general sense of te sentence.
