US Patent 11245648 Cognitive management of context switching for multiple-round dialogues

In embodiments, a method includes receiving a first user input to a chat managed by a multiple-round dialogue system, receiving a second user input to the chat, the second user input following the first user input, and embedding the first and second user inputs into first and second nodes, respectively, each node including a multi-dimensional vector. The method further includes determining, based at least in part on the first node and the second node, if a context of the second user input is the same as a context of the first user input, and, based on the determination, generating a chat reply to the second user input.
