Classification: CPC G | IPC G

Claim 6:
7. A question-answering (QA) system using memory-based reinforcement learning, the system comprising:
a receiver configured to receive, in an episodic memory reader (EMR),
streaming data about input context that is input from a user;
a storage configured to analyze, in the EMR, the received streaming data and store preset semantic information used for QA in an external memory, wherein the storage is configured to, in response to an empty memory entry of the external memory, map and store the semantic information to the empty memory entry, and to, in response to a full memory entry of the external memory, compute relative importance between the semantic information and data stored in the external memory and replace specific data stored in a memory entry corresponding to lowest relative importance compared to the semantic information with the semantic information and store the replaced semantic data; and
a determiner configured to, in response to an input of a question from the user, determine, in a pretrained QA model, an answer to the input question based
on semantic information stored in the external memory.
