The CIRCSE is a pluri- and interdisciplinary research centre of the Università Cattolica del Sacro Cuore (Milan, Italy). The main research interests of the centre are in the field of natural language processing and information extraction from written language texts in electronic form. The texts can be in ancient or modern languages and belong to different areas and genres.

Beside computational linguistics, the research areas covered by the works of the CIRCSE are philosophy of language and those specific expertises that are required by the individual texts to be processed (presently, mostly focussed on the philosophical area).

CIRCSE is the institutionalization of a research group (GIRCSE) started at the end of the 1970s at the Catholic University of the Sacred Heart of Milan by one of the pioneers of computational analysis of linguistic data, Father Roberto Busa.
