摘要：
A method for anonymization of unstructured data comprises determining structured references in the unstructured data; populating a table with the structured references; anonymizing the structured references in the table using ontological analysis; and rewriting the structured references in the unstructured data with the anonymized structured references from the table to produce anonymized data. A system for anonymizing unstructured data comprises an entity spotting module configured to determine structured references in the unstructured data and populate a table with the determined structured references; an anonymization module configured to anonymizing the structured references in the table using ontological analysis; and a replacement module configured to rewrite the structured references in the unstructured data with the anonymized structured references from the table to produce anonymized data.
