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 concluded 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 inspired (得到启发) by how we humans do things,” lead researcher Liu Tieyan said.

One method is called dual learning. 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 accurate (准确的).

Another method makes use of deliberation networks . 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 revise their own writing by going through it again and again.

Dear Editor,

My sister Becky keeps singing a song to me, though she knows I don’t like it. She even tells her friends to sing it to me! It really makes me angry.

Dale

Dear Dale,

Your sister seems to think it’s fun to make you angry, and the way you react (反应) may add to her fun.

You could try to ask your sister nicely to stop. Anytime she sings it in the future, don’t react or get angry. If you need to, leave the room. When you don’t react, she may become bored and stop singing.

Your parents may have advice on how to deal with this, too.

Editor

Dear Editor,

When people ask what I want to be when I grow up, I feel pressured because I want to do so many things. Most of the time, I answer, “I don’t know.”

Cindy

Dear Cindy,

Those people might just be trying to get to know you better. What they are really asking is, “What interests you now?”

The next time someone asks what you want to be, you could say something like “Today I think I’d like to be a writer or an artist. But ask me tomorrow, and I may change my mind”.

Editor

Dear Editor,

My best friend’s parents ended their marriage (婚姻). She’s having trouble going between houses and is sad all the time. It makes me feel sad, too.

Sally

Dear Sally,

It’s hard to watch a friend go through something hard. Help your friend make the best of her time at each house, asking her to hang out, or even just staying with her when she’s having a hard time. If she’s not better soon, talk to a trusted adult.
