Abstract

The invention relates to POI information classification based on a convolutional neural network, and belongs to the technical field of computers. According to the POI information classification methodand device based on the convolutional neural network, word segmentation processing is carried out on POI information, the POI information is converted to generate a vector matrix corresponding to thePOI information, and the vector matrix is processed through a pre-trained convolutional neural network model to determine the classification corresponding to the POI information. The convolutional neural network model used in the method is easy to train and obtain, the preprocessing process in the classification process is simple, and the classification efficiency is high and accurate.

Description

technical field [0001] The invention belongs to the field of computer technology, and relates to a method and a device for classifying POI (Point of Interest) information based on a convolutional neural network (Convolution Neural Network, CNN). Background technique [0002] In a geographic information system, it is necessary to classify POI information, for example, classify POI information according to a predetermined classification framework. POI information classification is mainly used for surrounding recommendation and query classification in map applications. Peripheral recommendations can greatly improve user experience, and query classification can provide users with more accurate search results. Therefore, improving the accuracy of POI information classification is very important for map applications (such as navigation applications, etc.). [0003] However, most of the methods currently used for POI information classification are machine learning or text matchin...
