In recent years, the study of language has assumed a central role within the representation of complex systems, triggering a greater interdisciplinarity among separate fields. Thus, new perspectives of analysis are stimulated: using computational linguistic tools to evaluate the impact of language in specific contexts and to understand how social and economic phenomena are developed. Adopting the Lexicon-Grammar theoretical framework, we used NooJ Application to process a corpus gathered with free texts from official universities' websites in order to explore the hidden intentions in Italian universities' web communication. Moreover, we created local grammars with single and compound words, associated to different missions of the university: teaching, research and third mission. The outputs demonstrate that teaching topic is the most common emerging from universities' web communication. As well as organizational aspects, renewing universities purpose implies the ability to communicate effectively the strategic goals, defining the university's role in the society and, meanwhile, aiming to engage several players.
