Abstract: Embodiments of the present disclosure disclose a method and apparatus for processing a weather alert text, an electronic device, a computer readable storage medium, and a computer program product, relate to the field of artificial intelligence technology such as natural language processing, cloud services, and computer vision. An implementation of the method includes: acquiring a to-be-processed weather alert text; extracting actual weather alert elements from the to-be-processed weather alert text using preset element matching templates, the element matching templates being obtained by clustering from contexts of a sample weather alert elements; and performing normalization processing on the actual weather alert elements, and combining obtained normalized alert elements in a preset order to obtain a key weather alert text. The application of this implementation may improve an accuracy of extracting weather alert elements and a generalization processing capability for various to-be-processed weather alert texts.

Abstract: A method and a device for determining a vehicle site location are disclosed in the present disclosure. The method includes: obtaining location information of multiple users and location information of at least two central points; calculating a distance between each user and each of the at least two central points according to the location information of multiple users and the location information of at least two central points; clustering the multiple users into at least two groups according to the distance; updating the location information of the central point according to the location information of the users in each group; if the location information of the central point satisfies a preset condition, determining the vehicle site location according to the location information of the central points and the number of the users in each group.
