The simplification candidates that are synonyms of the correct sense of the original word should be more semantically similar to the context of the original word.
we compute this feature by averaging the semantic similarities of the simplification candidate and each content word from the context of the original word: where C(w) is the set of context words of the original word w and v w is the GloVe vector of the word w. We use as context a symmetric window of size three around the content word.
