Our long paper “Explainable Prediction of Text Complexity: The Missing Preliminaries for Text Simplification” by Cristina Garbacea, Mengtian Guo, Samuel Carton and Qiaozhu Mei has been accepted at the ACL-IJCNLP 2021 main conference, which will be held in Bangkok, Thailand, during August 1-6, 2021. The camera ready version will be available soon, in the meantime please see the abstract of our paper below:
Text simplification reduces the language complexity of professional content for accessibility purposes. End-to-end neural network models have been widely adopted to directly generate the simplified version of input text, usually functioning as a blackbox. We show that text simplification can be decomposed into a compact pipeline of tasks to ensure the transparency and explainability of the process. The first two steps in this pipeline are often neglected: 1) to predict whether a given piece of text needs to be simplified, and 2) if yes, to identify complex parts of the text. The two tasks can be solved separately using either lexical or deep learning methods, or solved jointly. Simply applying explainable complexity prediction as a preliminary step, the out-of-sample text simplification performance of the state-of-the-art, black-box simplification models can be improved by a large margin.
