摘要：

As a subtask of lexical substitution, lexical simplification aims to provide simplified words with the same semantic meaning in context. Focusing on the task, this paper proposes a new method based on a hybrid ranking strategy. The method consists of three parts including 1) substitution generation leveraging semantic dictionaries, 2) substitution selection utilizing part-of-speech tagging and word stemming, and 3) substitution ranking based on a hybrid approach. Through the evaluation on standard datasets, our method outperforms state-of-the-art baselines including Word2vec and Four-step method, indicating its effectiveness in lexical simplification.
