The AI 2000 annual list, which uses computer algorithms to select the most influential scientists in 20 different subfields of Artificial Intelligence (AI), is one of the most important annual rankings of the AMiner platform. According to the editors, the lists are automatically generated using open access data from the internet for the last ten years (2011-2021) and evaluated based on various parameters, such as citation counts of selected top publications.

The AMiner platform tracks and analyzes more than 250 000 scientists worldwide with far more than 140 000 contributions at conferences and in journals to create the ranking. There are sometimes considerable differences among the data, for example with regard to the gender of the researchers. Only 9,1 percent of the AI scientists are female. The geographical location of the scientists listed on the AI 2000 also varies: about 170 are based in Europe, the majority are based in the USA.
