Today users can interact with popular virtual assistants such as Siri to accomplish their tasks on a digital environment. In these systems, links between natural language requests and their concrete realizations are specified at the conception phase. A more adaptive approach would be to allow the user to provide natural language instructions or demonstrations when a task is unknown by the assistant. An adaptive solution should allow the virtual assistant to operate a much larger digital environment composed of multiple application domains and providers and better match user needs. We have previously developed robotic systems, inspired by human language developmental studies, that provide such a usage-based adaptive capacity. Here, we extend this approach to human interaction with a virtual assistant that can first learn the mapping between verbal commands and basic action semantics of a specific domain. Then, it can learn higher level mapping by combining previously learned procedural knowledge in interaction with the user. The flexibility of the system is demonstrated as the virtual assistant can learn actions in new domains (e-mail, Wikipedia, etc.), and then can learn how e-mail and Wikipedia basic procedures can be combined to form hybrid procedural knowledge.
