Method and apparatus for evaluating translation quality

An apparatus for evaluating a translation quality, comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions when executed by the at least one processor, causing the at least one processor to perform operations, the operations comprising:
• acquiring a to-be-evaluated translation and a reference translation;
• inputting the to-be-evaluated translation and the reference translation into a pre-trained repetition coding model to obtain a semantic similarity between the to-be-evaluated translation and the reference translation, the repetition coding model being a neural network for calculating a probability of a pair of sentences being repetition sentences;
• analyzing the to-be-evaluated translation and the reference translation into two syntax trees respectively;
• calculating a similarity between the two syntax trees as a text similarity between the to-be-evaluated translation and the reference translation;
• and
• using a weighted sum of the semantic similarity and the text similarity as a translation quality score.

A non-transitory computer readable medium, storing a computer program, wherein the program, when executed by a processor, causes the processor to perform operations, the operations comprising:

• acquiring a to-be-evaluated translation and a reference translation;
• inputting the to-be-evaluated translation and the reference translation into a pre-trained repetition coding model to obtain a semantic similarity between the to-be-evaluated translation and the reference translation, the repetition coding model being a neural network for calculating a probability of a pair of sentences being repetition sentences;
• analyzing the to-be-evaluated translation and the reference translation into two syntax trees respectively;
• calculating a similarity between the two syntax trees as a text similarity between the to-be-evaluated translation and the reference translation;
• and
• using a weighted sum of the semantic similarity and the text similarity as a translation quality score.
