The multidimensional character of text has generated an increased interest among linguists over the last decades. Text and textology have become important research directions and as a result, today we have text linguistics, another branch of general linguistics.

M., Biber D., Trosborg A., Werlich E., Hatim B. and Mason I., de Beaugrande D. and Dressler W., etc.
