Complexity in language and text [PDF ebook] 

This book explores differrent paths. The models  that are proposed account for complexity on more objective grounds and independently of processing  difficulty. Complexity is defined as the consequence of marked linguistic and textual chioices interplaying  in the text, and is described and modelled with recourse to semiotic categories. In this view, the emergence of complexity, which is not subject to contextual variables, is always motivated and can be explained and predicted. What is more, it escapes sanctions and may even recover a positive value, of the kind we assign to whatever is rich, intriguing and attractive.
