For decades, educators have relied on readability metrics that tend to oversimplify dimensions of text difficulty. This study examines the potential of applying advanced artificial intelligence methods to the educational problem of assessing text difficulty. The combination of hierarchical machine learning and natural language processing (NLP) is…

A survey of the current research on readability formulas is presented in this paper, which distinguishes this research from research on the more general questions that surround formulas: What features of a text, particularly the language it is written in, make the text easy or difficult to read? and, What will predict that readers with particular…

Discusses four general areas of linguistics studies that are particularly relevant to literacy issues: (1) discourse analysis, including text analysis, spoken and written language, and home and school discourse; (2) relationships between speech and writing, the distance between dialects and written norms, and developmental writing; (3)…

Research from several disciplines has been examined to create this literature review of information on document design, the overall movement toward producing public documents that the intended users can understand. Six chapters review appropriate research from the areas of psycholinguistics, cognitive psychology, instructional research,…

Ease of language processing varies with the nature of the language involved. Ordinary spoken language is the easiest kind to produce and understand, while writing is a relatively new development. On thoughtful inspection, the readability of writing has shown itself to be a complex topic requiring insights from many academic disciplines and…

One factor that contributes to the difficulty that a reader may encounter when reading a text is the syntactic complexity of the constructions used in the text. Examples of altered text constructions include the transformations of subjects of subordinate clauses, making them either the subjects or the objects of main clauses. When the conditions…

Linguistic cohesion involves the semantic and syntactic relationships that link sentences together. Research on linguistic cohesion is related to readability and to developmental and ability-level issues in reading/writing. Instructional strategies for low-ability readers/writers include predicting comprehension problems through cohesion analysis…
