What are the translation theories?

1. Interpretation theory: Propose the triangle translation process hypothesis, and think that the translation object should be the meaning of the source language information rather than the language shell.

2. Cognitive load model theory: It was first put forward by John Sweller, a cognitive psychologist at the University of New South Wales, Australia, in 1988. It was put forward on the basis of Miller's early research.

3. Theory of thinking adaptive control mode: Any skilled behavior needs to transform declarative knowledge into procedural knowledge.

4. Faithfulness and elegance: put forward by Yan Fu, an emerging enlightenment thinker in the late Qing Dynasty. Generally speaking, translation should conform to the characteristics of Chinese and pay attention to the integrity of sentences, that is, the accuracy of content, the fluency of grammatical structure and the literariness of language carrier.

Problems faced by machine translation

The quality of machine translation is still difficult to reach the level of "faithfulness and elegance"; The quality of machine translation is the key to the success of machine translation system. China mathematician and linguist Zhou Haizhong once pointed out in the article "Fifty Years of Machine Translation":

To improve the quality of machine translation, the first thing to be solved is the language itself rather than the programming problem; It is certainly impossible to improve the quality of machine translation by relying on several programs to make a machine translation system;

In addition, it is impossible for machine translation to reach the level of "faithfulness, expressiveness and elegance" before human beings understand how the human brain makes fuzzy recognition and logical judgment on language. These are the bottlenecks that restrict the improvement of machine translation quality.
