Claim 0:
1. A question-answering (QA) method using memory-based reinforcement learning, the method comprising:
receiving, in an episodic memory reader (EMR), streaming data about an input context that is input from a user;
analyzing, in the EMR, the received streaming data and storing preset semantic information used for QA in an external memory, wherein the storing comprises, in response to an empty memory entry of the external memory, mapping and storing the semantic information to the empty memory entry, and, in response to a full memory entry of the external memory, computing relative importance between the semantic information and data stored in the external memory and replacing specific data stored in a memory entry corresponding to lowest relative importance compared to the semantic information with the semantic information and storing the replaced semantic data; and,
in response to an input of a question from the user, determining, in a pretrained QA model, an answer to the input question based on semantic information stored in the external memory.
