The invention provides a feature construction method and device based on an artificial intelligence model. The method comprises the steps that DNS logs are collected; arranging and de-duplicating the DNS log to obtain a de-duplicated log; feature fields are extracted from the duplicate removal logs; the feature fields comprise a request domain name field, a response length field, a query type field and a return code field, the problem part comprises an entity number field, and the authority area comprises an entity number field and a survival time feature field; performing feature vectorization processing on the feature field to obtain a feature vector; and constructing a polysemy feature based on the feature vector. Therefore, by implementing the implementation mode, a large number of polysemy features can be generated, so that the large number of polysemy features can train a higher-quality DGA artificial intelligence detection model, and the detection false alarm rate can be remarkably reduced. 本申请提供一种基于人工
