Artificial intelligence(AI,人工智能)can help us make phone calls, guide us to where we want to go, or play games. Researchers from Microsoft recently created the first machine translation system that can translate news articles from Chinese to English, Business Standard reported.
According to Microsoft's official website, researchers tested the system by asking it to translate hundreds of sentences taken from news stories.They concluded that the system's translations were as good as the human translations. This is partly because different words can be used to express the same meaning. It can be hard to say which word is more “correct”.
“Much of our research is really inspired by how we humans do things,” lead researcher Liu Tieyan said.
One method is called dual learning(对偶学习). In this method, the system translates every sentence from Chinese to English, as well as translating the sentences back from English into Chinese.This is similar to what humans do to make sure their translations are accurate.
Another method makes use of deliberation networks. This is when the system is made to translate the same sentence over and over. Gradually, the system improves the quality of its translation, like humans who would improve their own writing by going over it again and again.
A. Machine translation is always challenging.
B. However, experts used several methods to improve the system's translation abilities.
C. Then, language experts compared the results to two translations that were done by humans.
D. Researchers collected a lot of data to help the system learn and improve.
E. And now, AI can do even more things.
F. Researchers have worked on machine translation for decades.
G. This way, the system can improve itself and learn from its own mistakes.
