Urban functional area sample labeling method and device, electronic equipment and storage medium

The embodiment of the invention provides an urban functional area sample labeling method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining at least one urban functional area; determining topic probability distribution of each urban functional area by utilizing a predefined sparse topic model, selecting the urban functional area of which the topicprobability distribution meets a set condition as a pure sample, and marking the category of each urban functional area in the pure sample; based on the first classification model and the known categories of the urban functional areas, determining the category membership information entropy of each unlabeled urban functional area, and determining the unlabeled urban functional areas of which the membership information entropy is greater than a first threshold value as confused samples; and performing classification identification on the confused sample based on the second classification model,determining the category
