abstract = "In recent years, the main focus of research on automatic readability assessment (ARA) \
has shifted towards using expensive deep learning-based methods with the primary goal of increasing models{'} accuracy. \
This, however, is rarely applicable for low-resource languages where traditional handcrafted features are still \
widely used due to the lack of existing NLP tools to extract deeper linguistic representations. In this work, \
we take a step back from the technical component and focus on how linguistic aspects such as mutual intelligibility \
or degree of language relatedness can improve ARA in a low-resource setting. We collect short stories written in three \
languages in the Philippines{---}Tagalog, Bikol, and Cebuano{---}to train readability assessment models and explore the \
interaction of data and features in various cross-lingual setups. Our results show that the inclusion of CrossNGO, \
a novel specialized feature exploiting n-gram overlap applied to languages with high mutual intelligibility, \
significantly improves the performance of ARA models compared to the use of off-the-shelf large multilingual \
language models alone. Consequently, when both linguistic representations are combined, we achieve state-of-the-art \
results for Tagalog and Cebuano, and baseline scores for ARA in Bikol.",
