With the continuous development and popularization of AI technology, in the field of news communication, more and more media begin to use AI technology for news creation and communication. Although AI has greatly improved the speed of collecting news data and generating news articles, as the application of AI is still in the exploratory stage at present, the extensive use of AI has resulted in the spread of rumors and infringement of intellectual property rights in the network. Through the experimental method of case analysis, this study selected Xinhua News Agency with typical characteristics of traditional news media and typical news we media as the case, made a comparative analysis of these two different media, and concluded that there are differences in AI technology sources and news production links between traditional news media and news we media in China at present. In addition, most news we media using AI lack the important part of self-censorship in the production process, thus resulting in negative social impacts. Based on the above analysis, some suggestions are put forward to solve this problem. The case analysis of the use of AI in news we media in this study fills some gaps in this field and provides a foundation for future research in this field.
