Claim 0:
1. A system for automated text anonymisation of documents, the system comprising:
at least two symbolic artificial intelligence (AI) pipeline components including named-entity recognition (NER) processes that detect personal information in at least a first document of the documents, at least one of the symbolic artificial intelligence (AI) pipeline components generating at least one label that indicates a type of the personal information and indicates a position of the at least one label in the first document;
a masking component receiving the at least one label and applying a mask to the first document based on the position of the at least one label with the first document, the masking component generating a de-identified first document; and
a zoning component, connected to at least one of the symbolic artificial intelligence (AI) pipeline components or the masking component, that executes a trained machine learning model to identify key areas of the first document,
wherein:
the symbolic AI pipeline components comprise a time-shift component that receives a first date or time being a second text item of the personal information from at least the first document and generates a second date or time by adding or subtracting a predetermined time period from the first date or time, and
the second date or time is included in the at least one label.
