The work investigates how speakers use language, aiming to explain how the structure and composition of our texts 'photograph' our life experiences, our social identity. To do so, the study uses educational technology in the compilation and exploration of bigdata, pointing out advantages in the construction of computational tools and in the use of technological resources that make intelligent readings of cybercorpus. The book also includes reflections about the teaching-learning process of textual production and revision in basic education, digital literacy, work with cybercorpus and public policies aimed at making more efficient instructional materials.
