The following research has as its starting point the previous existence of different approaches to the study of digital literacy, which reflect a specialisation by area of study as well as connections and complementarity between them. The paper analyses research from the last 50 years through 11 key terms associated with the study of this subject. The article seeks to understand the contribution of each term for an integrated conceptualisation of digital literacy. From the data science approach, the methodology used is based on a systematized review of the literature and a network analysis using Gephi. The study analyses 16,753 articles from WoS and 5,809 from Scopus, between the period of 1968 to 2017. The results present the input to each key term studied as a map of keywords and a conceptual framework in different levels of analysis; in these, we show digital literacy as a central term that connects and integrates the others, and we define it as a process that integrates all the perspectives. The conclusions emphasise the comprehensive sense of digital literacy and its social condition, as well as the transversality to human life. This research aims to understand the relationships that exist between the different areas and contribute to the debate from a meta-theoretical level, validating meta-research for this interdisciplinary purpose.
