As smart technology evolves, algorithms gradually infiltrate news and information of production and pushing in. However, algorithms are not completely value-neutral technologies; they are the product of social biases in the age of artificial intelligence. In the operation of algorithms, bias can arise from the design of algorithmic rules, the collection, processing and application of data, and the computational process. Algorithm bias not only deviates from fair and impartial journalistic norms, challenges users' right to know and information choice, but also deconstructs social consensus and triggers public opinion risks. Therefore, this study suggests that algorithmic bias should be regulated and controlled in four aspects: laws and regulations, technological innovation, third-party auditors and algorithmic values.
