An HR (Human Resources) department in a large organization receives inquiries/requests from employees on multiple topics, which are quite different from one another. As an example, an employee can send requests dealing with health conditions, compensation/taxation, events of life (marriage, death of a relative. . . ). These data can be used for many different queries that can be useful for analysis purposes (Example: ‘How many people have had COVID during 2021‘). However, HR tickets typically contain personal data, that cannot be processed without the consent of the data subject according to the European privacy regulation (GDPR). To be able to process documents with personal data, we can identify the pieces of information that qualify as personal data in a communication and subsequently anonymize such information using the appropriate techniques.
