• processing the medical records in accordance with a data extraction model to extract from each record one or more intervention events, each representative of a medical intervention;

• accessing a dataset of indexing intervention events, each associated in the dataset with a corresponding representation in terms of a set of attributes, including at least one falling into each of said defined set of attribute domains, and based on comparison of the attributes of the extracted intervention events and the stored indexing intervention events, identifying a closest matching indexing intervention event to each extracted intervention event;
• and
• classifying each of the medical records in accordance with the indexing intervention event or events identified for that record;
• selecting one of a plurality of indexing intervention events for use as a basis for aggregating the plurality of medical records, the selecting being based on information pertaining to a user;
