AI translation technology has the following difficulties and features:

AI translation technology is a new technology whose difficulties lie in Automated Reasoning, Machine Learning and Natural Language Understanding.

1.Automated Reasoning
Automated Reasoning is a classic research branch of AI, and has been one of the most popular research topics of AI. The research of dynamic evolution characteristics of knowledge base and feasible reasoning is the newest topic, and the development of automated reasoning will greatly enhance the quality machine automatic translation.

2. Machine Learning
To make the computer more intelligent, sufficient knowledge must be transmitted to it. But the traditional way of manual inputting is way from meeting the requirements of computers, so we have to let computers have the ability of automatically acquiring information. As to the aspect of AI translation technology, it requires the machine to acquire the knowledge of words, and sentences (including sentence patterns, sentential pairs and structures) etc.

3. Natural Language Understanding
If we can let computers understand human languages, then the use rate of computers will be greatly increased and even untrained people can control computers and this is an important research direction of AI. It needs AI translation integrates sound system and with the assist of other systems, transform language instruction into unified machine instruction.
