In its daily activities, the school produces large amounts of textual data in response to different needs, ranging from planning activities, to supporting internal and external communication and self-assessment. These data represent a vast and varied information asset which needs to be profitably analysed to monitor and study ongoing phenomena in the field of education. To profile the contents conveyed by this continuously growing documenta¬tion, we propose advanced methods and techniques for knowledge extraction based on language technologies. The paper illustrates the first and promis¬ing results of the proposed methodology for monitoring educational strategies through time, space and different types of schools, starting from free texts. The methodology has been tested within two scenarios focusing on i) the analysis of the strategic choices and actions implemented by schools to achieve improvement and innovation objectives, and ii) the monitoring of the technical-professional and soft skills developed in School-Work Alternation experiences. Although preliminary, achieved results show that Natural Language Processing enabled methods and techniques can lead to effective and exhaustive school profiling.
