Abstract: A method includes receiving data comprising a plurality of requests and a plurality of responses to the requests. The requests and the responses are associated with a virtual assistant programmed to address the plurality of requests. In the method, a machine learning (ML) classifier is used to partition the requests into a plurality of partitions corresponding to a plurality of request types. An interface for a user is generated to display a subset of the requests corresponding to at least one partition of the plurality of partitions and to display a response corresponding to the subset of the plurality of requests, wherein the response is based on one or more of the plurality of responses. The interface is configured to permit editing of the response by the user. The method also includes processing the response edited by the user, and transmitting the edited response to the virtual assistant.

Abstract: A method for model management includes receiving data on which to base a model, evaluating the received data against a plurality of existing models and data associated with each of the plurality of existing models, determining whether any of the plurality of existing models can be used as the model or as a basis to develop the model for the received data, and providing a user with the existing models that can be used as the model or as a basis to develop the model for the received data.

Abstract: A method for transaction analysis comprises extracting a plurality of character groups from a plurality of transaction identifiers, determining an inverse document frequency value for each of the plurality of character groups, generating, for a first transaction and a second transaction, respectively, a first transaction signature and a second transaction signature corresponding to the plurality of character groups, and computing a distance between the first and second transaction signatures.

Abstract: A system for re-authentication comprises a re-authentication server, implemented by one or more processing devices. The re-authentication server is configured to receive a re-authentication request from an organizational server, process the re-authentication request, and transmit a re-authentication prompt to a user device, wherein the re-authentication request is transmitted from the organizational server to the re-authentication server without being communicated to an application server configured to receive a request for at least one of a service and data from the user device.
