Readability, Multiword Expressions, Propositional Density, Formulaic Expressions, Text Difficulty
There are two general approaches to readability: classic and cognitive. There are more than 50 classic procedures for predicting text difficulty, which are usually referred to as readability formulas. Propositional density has been proposed as one criterion for determining readability. Some criticisms have been proposed against taking propositional density as a criterion for readability and such criticisms would be best refuted through taking formulaic expressions as idea units to be taken into account when determining readability. After going through a library research, the authors of this study came arrived at the conclusion that in decomposing utterances into their constituents, taking multiword expressions (formulaic expressions) as propositional units is quite telling and beneficial.
