Quantifying word informativeness and its impact on eye-movement reading behavior: Cross-linguistic variability and individual differences.

ABSTRACT: The importance or centrality of a linguistic unit to a larger unit's meaning is known to affect reading behavior. However, there is an ongoing debate on how to quantify a unit's degree of importance or centrality, with previous quantifications using either subjective ratings or computational solutions with limited interpretability. Here we introduce a novel measure, which we term "informativeness", to assess the significance of a word to the meaning of the sentence in which it appears. Our measure is based on the comparison of vectorial representations of the full sentence with a revised sentence without the target word, resulting in an easily interpretable and objective quantification. We show that our new measure correlates in expected ways with other psycholinguistic variables (e.g., fr
