Abstract: A method for organizing medical record data based on classification of a set of medical records in accordance with an indexing intervention event identified for each record, associated with a medical intervention. The method is based on extracting for each of a plurality of medical records one or more candidate intervention events, and then mapping these to a dataset (or ontology) of standard intervention event names (indexing intervention events) in order to identify a closest matching indexing event for each extracted intervention event. The mapping is based on breaking down each extracted intervention event into a set of characterizing attributes of particular domains or types and then comparing these with corresponding attribute sets for each of the indexing events in the dataset. A closest match is found, and each medical record is classified according to the closest matching indexing event. Data is then aggregated based on the classifications, and also based on information about a user, e.g.
