Abstract: Techniques are disclosed relating to text sanitization. Given textual data, a computer system identifies tokens predicted to constitute sensitive information. Multi-field data structures (e.g., triplets) are generated for the identified tokens that include questions, answers, and corresponding context. These data structures are supplied to a pre-trained multiple-choice question (MCQ) reading comprehension model. The model outputs, for each data structure, a probability that the question and answer for a given data structure, provided the context, is accurate. A post-processing module can then rank probabilities in this set of probabilities and select the multi-field data structure with the highest probability (in some cases, a programmable threshold must also be met). The selected multi-field data structure is then used to select category information to be used in sanitizing the textual data.
