Accenture has patented what they call an automatic ticket resolver, which essentially uses AI to help guide the resolution of tickets, and interlock it with work flows.
Their automation includes the ability within that work flow to call out to not only the scripts or the robotic process automation, that may execute to resolve the problem, but also to their BOT framework, which is included in that platform, and that uses speech, understands natural language, handles questions and answers, and more.
