Methods and systems are provided for classifying free-text content using machine learning. Free-text content (e.g., customer feedback) and parameter values organized according to a schema are received. A free-text corpus is generated, and an artificial-text corpus is generated by applying rules to the parameter values. The artificial-text corpus is generated by converting the parameter values into a finite set of words based on the rules and concatenating the words of the finite set of words into a fixed sequence wordlist. Feature vectors (e.g., sentence embeddings) based on the free-text corpus and the artificial-text corpus are combined and forwarded to a machine learning model for classification. The machine learning model may be trained with a bias towards a specified metric (e.g., precision, recall, F1 score). The model may be trained using transfer learning with training data from a different category of free-text content (e.g., a different category of customer feedback).

A Trusted Activation License (TAL) can be comprised of a key unique to a Trusted Platform Module (TPM) and identifying information of the software applications bundled with the computing device having that TPM. To activate the software applications, the identifying information in the TAL can be compared against that of the software applications being activated, and the unique TPM key in the TAL can be compared against that of the TPM on the computing device on which the activation is taking place. Subsequent validations can be based on a protected association between the TAL and an Attestation Identity Key (AIK) that can be generated by the TPM as part of the activation step. Optionally, Platform Configuration Registers (PCRs) of the TPM can be periodically changed during validation to protect against useage of one TPM for validations on multiple computing devices.
