Summary:The invention provides a point of interest (POI) identification method and device. The POI identification method comprises the following steps that A. classifiers are trained respectively in advance aiming at each node of a decision-making tree, particularly, a training set corresponding to each node of the decision-making tree is determined, execution is carried out respectively aiming at each node of the decision-making tree, the training set corresponding to the current node serves as positive sample data of the current node, the training sets of other nodes corresponding to the same father node in the decision-making tree serve as negative sample data of the current node, and the classifier of the current node is trained; B. from the root node of the decision-making tree, the POIs to be labeled are judged whether belong to the node judged currently step by step through the classifier of each node, and the POIs to be labeled are labeled through the judgment result. By means of the POI identification method
