Claim 24:
25. A computer system comprising:
an artificial intelligence (AI) platform in communication with a processor, the AI platform having tools to direct performance of a dialog system, the tools comprising:
a dialog manager configured to receive natural language (NL) related to interaction with an automated virtual dialog agent of the dialog system, the NL comprising one or more dialog events, each of the dialog events including input and output, the input comprising one or more input instances and the output comprising one or more corresponding output instances;
an AI manager, operatively coupled to the dialog manager, configured to apply the received one or more dialog events to a learning program, the learning program configured to:
represent the one or more dialog events in a model, leverage the model to compare text of question answer pairs, and determine one or more similarities and differences in terms of concept relations, wherein the model represents the one or more dialog events;
identify a knowledge gap between the one or more input instances and the one or more corresponding output instances;
measure distance between one or more subgraphs of the model with a common node label, wherein the measured distance corresponds to complexity of the identified knowledge gap;
leverage structure and functionality of one or more corresponding models to compare content and to determine any similarities or differences corresponding to concept relations;
provide an ontology representation of any similarities or differences corresponding to concept relations; and
dynamically generate one or more alternative knowledge items to bridge the knowledge gap; and

a director configured to refine the automated virtual dialog agent, the refinement corresponding to the bridged knowledge gap.
