    Imagine you are thinking about entering a senior high school, but have questions. So you go to the school's website to find answers. A message appears on your computer and says, "How can I help?" You are not communicating with a human being, but a chatbot. It is using artificial intelligence (AI) to communicate with you. This might sound strange, but in recent years, chatbots have become an usual tool for banks and large companies around the world.

Having workers answer people's questions and complaints can be expensive. And workers canonly work several hours a day, making customers wait longer for a response (答复). So not only companies, but more schools have also begun using chatbot technology, says Keith Rajecki. He is with Oracle Higher Education, a computer software company that serves these institutions.

Rajecki notes that reducing costs and response time is one of the main reasons why schools and companies are turning to this technology. However, the purpose of many schools is to find ways to better serve students, since students are used to communicating online through Facebook or WeChat, says Rajecki.

Now Oracle is offering many schools a chatbot which can do everything from helping students register (注册) for classes to helping them ask for a few days off. Oracle is not the only company working on chatbot technology. Businesses like AdmitHub and Ivy.ai are involved in similar efforts.

Western Governors University, or WGU, also received a $750,000 award to experiment with a new kind of chatbot. "We're not trying to create a bot that answers simple questions," said Jason Leven, the director of WGU Labs. "We're trying to create a chatbot that can help decision making for students."

Ian Jacobs is with the market research company Forrester. He suggests that technology like chatbots can work well if it is able to do what users ask of it. Jacobs says the problem will appear when cost cutting becomes an important reason for using the technology. This means schools and companies are more likely to try using chatbots for things they are not yet able to do, such as communicating in the way humans do. For one thing, there are hundreds of ways to word even simple requests. For another, chatbots aren't able to deal with emotions (感情). They can't understand how humans feel, not to speak of comforting (安慰) them.
