Claim 17:
18. A computer-implemented method directed at performance of a dialog system, the method comprising:
receiving, by a processor of a computing device, natural language (NL) relating to interaction with an automated virtual dialog agent of a dialog system, the NL comprising one or more dialog events, each of the one or more dialog events including input and output, the input comprising one more input instances and the output comprising one or more corresponding output instances or output actions;
applying, by the processor, the received one or more dialog events to an artificial intelligence (AI) platform comprising a learning program, the applying comprising:
interpreting the one or more input instances and the one or more corresponding output instances or output actions, including representing the one or more dialog events in a model;
identifying a knowledge gap associated with the interpreted one or more input instances and the one or more corresponding output instances or output actions;
measuring distance between subgraphs of the model with a common node label;
leveraging structure and functionality of one or more corresponding models to compare content and to determine any similarities or differences corresponding to concept relations;
providing an ontology representation of any similarities or differences corresponding to concept relations; and
dynamically generating one or more alternative knowledge items to bridge the knowledge gap; and

refining the automated virtual dialog agent in relation to the one or more dialog events corresponding to the bridged knowledge gap to improve performance of the dialog system.
