The embodiment of the invention discloses a vehicle type determination method and device based on a support vector machine. A specific implementation mode of the method comprises the following steps: performing word segmentation on an alarm receiving and processing text to be classified to obtain a corresponding word segmentation sequence; determining a text feature vector of the alarm receiving and handling text to be classified based on the obtained word segmentation sequence; for each vehicle type in a preset vehicle type set, inputting the text feature vector into a classification model corresponding to the vehicle type to obtain a classification result used for indicating whether the alarm receiving and handling text to be classified corresponds to the vehicle type, and the classification model corresponding to each vehicle type is obtained based on training of a support vector machine; and a vehicle type set corresponding to the to-be-classified alarm receiving and processing text is generated by using each target vehicle type in a preset vehicle type set, and a classification result indicates that the to-be-classified alarm receiving and processing text corresponds to the target vehicle type. According to the embodiment, vehicle type classification is automatically carried out on the alarm receiving and processing text.
Description
technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a method and device for determining a vehicle type based on a support vector machine. Background technique [0002] At present, the 110 police officers of the public security organs will enter the police text when they receive the police. The police officer will enter the police text after the police is over. The receiving and handling text includes the above-mentioned receiving and handling text and the warning text. [0003] In practice, there are a large number of police texts related to vehicle information, such as traffic accidents involving vehicles, economic disputes involving vehicles, theft involving vehicles, and so on. In order to statistically analyze the relevant data of different types of vehicles (for example, motor vehicles and non-motor vehicles) in the process of receiving police, case analysts often give the police situation r...
