Abstract
Current English lexical simplification (LS) methods adopt one simplification scheme for all users, regardless of individual users' language proficiency. To solve the problem, we propose a personalized English LS method for Chinese based on their English certification. Specifically, our method only simplifies these words that need to be simplified and utilizes both pertained language modeling BERT and Thesaurus to generate the best substitutes. To our knowledge, this is the first work that focuses on personalized English LS for Chinese. Experimental results show that our method obtains the most suitable simplification compared with the baselines.
