Electronic device for obtaining sentence corresponding to context information and operating method thereof

An electronic device for obtaining a sentence corresponding to context information, the electronic device comprising:

• a memory configured to store at least one data used for decoding the context information;
• at least one processor configured to:
• obtain first output information including at least one word output by decoding the context information based on the at least one data,
• based on detecting that a first token is not included in the first output information, determine whether a number of words included in the first output information is greater than or equal to a reference value,
• based on a result of the determining, replace the at least one data with other data and
• obtain the sentence corresponding to the context information based on at least one output information obtained by decoding the context information based on the other data;
• and
• an output interface configured to output information corresponding to he obtained sentence.

A non-transitory computer-readable medium configured to store instructions which, when executed by at least one processor of an electronic device for obtaining a sentence corresponding to context information, cause the at least one processor to:

• obtain first output information including at least one word output by decoding the context information based on at least one data;
• based on detecting that a first token is not included in the first output information, determine whether a number of words included in the first output information is greater than or equal to a reference value;
• based on a result of the determining, replace the at least one data with other data;
• and
• obtain the sentence corresponding to the context information based on at least one output information obtained by decoding the context information based on the other data.
