We present a method for lexical simplifica- tion. Simplification rules are learned from a comparable corpus, and the rules are applied in a context-aware fashion to input sentences. Our method is unsupervised. Furthermore, it does not require any alignment or correspon- dence among the complex and simple corpora. We evaluate the simplification according to three criteria: preservation of grammaticality, preservation of meaning, and degree of sim- plification. Results show that our method out- performs an established simplification base- line for both meaning preservation and sim- plification, while maintaining a high level of grammaticality.
