  • Patent number: 8888493
    Abstract: A computer-implemented method, system, and computer program product for automatically assessing text difficulty. Text reading difficulty predictions are expressed on a scale that is aligned with published reading standards. Two distinct difficulty models are provided for informational and literary texts. A principal components analysis implemented on a large collection of texts is used to develop independent variables accounting for strong intercorrelations exhibited by many important linguistic features. Multiple dimensions of text variation are addressed, including new dimensions beyond syntactic complexity and semantic difficulty. Feedback about text difficulty is provided in a hierarchically structured format designed to support successful text adaptation efforts.

  • Patent number: 8892421
    Abstract: Systems and methods are provided for determining a difficulty level of a text. A determination is made as to a number of cohesive devices present in a text. A further determination is made as to a number of cohesive devices expected in the text. A cohesiveness metric is calculated based on the number of cohesive devices present in the text and the number of cohesive devices expected in the text, where the cohesiveness metric is used to identify a difficulty level of the text.
