Artificial intelligence （AI， 人工智能） can help us make phone calls． It can guide us to where we want to go． It can play games． And now， AI can do even more things．
Researchers from Microsoft have 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． Then， language experts compared the results to two translations that were done by humans． The experts said that the system's translations were as good as the human translations．
Machine translation is always challenging． 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"．
Experts used several methods to improve the system's translation abilities． "Much of our research is really learned from 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 translates the sentences back from English into Chinese．This way，the system can improve itself and learn from its own mistakes． This is similar to what humans do to make sure their translations are exact．
Another method makes use of deliberation networks （推敲网络）．The researchers taught the system to repeat the process of translating the same sentence over and over．Gradually， the system can improve the quality of its translations． This is similar to how people correct their own writing by going through it again and again．
