13. A system comprising: a first memory device; a second memory device; and a processor to execute processor-executable program code in order to cause the system to: receive first text, the first text comprising a first identifier and first additional text; store the first additional text in an area of the first memory device associated with the first identifier; receive second text, the second text comprising the first identifier and second additional text; store the second additional text in the area of the first memory device associated with the first identifier; determine that a characteristic of text stored in the area of the first memory device has reached a threshold, the text stored in the area of the first memory device comprising at least the first additional text and the second additional text; in response to the determination, generate a semantic representation of the text stored in the area of the first memory device; and store the semantic representation in association with the first identifier in the second memory device.
