Abstract: Generally discussed herein are devices, systems, and methods for detecting a conversation with a virtual agent is offtrack and responding appropriately. A method can include receiving a prompt, expected responses to the prompt, and a response of an interaction session with the virtual agent, the interaction session to solve a problem of a user, determining whether the response indicates the interaction session is in an offtrack state based on the prompt, expected responses, and response, in response to a determination that the interaction session is in the offtrack state, determining a taxonomy of the offtrack state, and providing, based on the determined taxonomy, a next prompt to the interaction session.

Abstract: A method and system for exchanging clinical trial operational data by using a centralized shared server system connected to a plurality of shared servers. The system and method manage a plurality of clinical trial-related applications by creating a plurality of tables stored within the shared database of the shared database system connected to a centralized shared server system within a virtual network for updating and sharing among clinical trials. The current system and method allow exchanging clinical trial operational data between a centralized shared server system and a plurality of shared servers to delegate responsibility to other clinical trial organization users for producing subsets of clinical trial operational data with limited data access rights.
