Abstract: Provided is an organometallic compound represented by Formula 1, an organic light-emitting device including the same, and an electronic apparatus including the organic light-emitting device. Ir(L1)(L2)(L3)??Formula 1 L1 to L3 in Formula 1 are the same as described in the present specification.

Abstract: An electronic device includes a microphone, a memory, and a processor configured to obtain a first natural language understanding result for a first user voice obtained through the microphone based on a first text corresponding to the first user voice, provide a first response corresponding to the first user voice based on the first natural language understanding result, identify whether the first user voice includes a tracking element based on the first natural language understanding result and a second text corresponding to the first response, based on identifying that the first user voice includes the tracking element, store the first text, the first natural language understanding result and the second text in the memory, and obtain a third text corresponding to the first response based on the first natural language understanding result.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a microphone, a memory storing at least one instruction, and a processor connected to the microphone and the memory configured to control the electronic apparatus, and the processor, by executing the at least one instruction, may, based on receiving a user voice signal through the microphone, obtain a text corresponding to the user voice signal, identify a plurality of sentences included in the obtained text, identify a domain corresponding to each of the plurality of sentences among a plurality of domains, based on a similarity of a first sentence and a second sentence, among the plurality of sentences, having a same domain being greater than or equal to a threshold value, obtain a third sentence in which the first sentence and the second sentence are combined by using a first neural network model, and perform natural language understanding for the third sentence.
