Perform back translation at the same time The accuracy of the translation result is expressed as a score (0.0 to 1.0) indicating the degree of semantic similarity between the original sentence and the translated sentence. The evaluation value is calculated by sentence embedding (two strings are expressed as vectors and the distance between the two vectors). The evaluation value is the semantic distance between two sentences, and the higher the similarity (the higher the translation accuracy), the higher the value is 0.
