Classification: CPC G | IPC G

Claim 9:
10. A method for automated text anonymisation of documents, the method comprising:
processing at least one first document of the documents by applying symbolic artificial intelligence (AI) pipeline components including named-entity recognition (NER) processes that detect personal information in the at least one first document;
processing the at least one first document by applying a zoning component, connected to at least one of the symbolic artificial intelligence (AI) pipeline components or a masking component, that executes a trained machine learning model to identify key areas of the first document;
outputting the personal information or the key areas individually as at least one label to a label file associated with the at least one first document, each of the at least one label including a type of the personal information or key area and a position of the personal information or key area in the at least one first document; and
generating, via the masking component, at least one first de-identified document based on the label file and the at least one first document, the at least one first de-identified document having a mask at a mask position corresponding to the position of personal information in each of the at least one label in the at least one first document,
wherein the method further comprises:
receiving at a time-shift component of the symbolic AI pipeline components a first date or time being a second text item of the personal information from the at least one first document;
generating a second date or time by adding or subtracting a predetermined time period from the first date or time; and
incorporating the second date or time into a second label of the at least one label corresponding to the second text item of the personal information.
