1. A computer system comprising:

  • a processing unit operatively coupled to memory;

    an artificial intelligence platform, in communication with the processing unit and memory;

    a knowledge engine operatively coupled to the processing unit to train a machine learning model (MLM), the knowledge engine configured to;

    select a first MLM from a natural language (NL) processing library of MLMs, aligned to a knowledge domain expressed in a first knowledge graph (KG);

    receive NL input and query the input against the first KG, and extract one or more triplets from the first KG;

    apply the selected MLM to a second KG different from the first KG, and extract one or more triplets from the second KG, wherein each triplet includes a subject, object, and a relationship;

    for each extracted triplet;

    obtain a blockchain (BC) identifier associated with each triplet; and

    identify a triplet veracity value from a corresponding BC ledger;

    detect a modification of the first KG from the extracted one or more triplets from the second KG, wherein the modification is selected from the group consisting of;

    content and structure, and combinations thereof; and

    evaluate the detected modification, including employ the obtained BC identifier to assess veracity of the detected modification; and

    dynamically augment the first MLM responsive to the received NL input.
