SimpLex: a lexical text simplification architecture

1 code implementation14 Apr 2023 Ciprian-Octavian Truică, Andrei-Ionut Stan, Elena-Simona Apostol

Thus, the main contributions of this paper are: (1) We propose a new Word Embedding and Transformer based algorithm for text simplification; (2) We design \textsc{SimpLex} -- a modular novel text simplification system -- that can provide a baseline for further research; and (3) We perform an in-depth analysis of our solution and compare our results with two state-of-the-art models, i. e., LightLS [19] and NTS-w2v [44].
