Abstract: Embodiments of the present disclosure disclose an artificial intelligence based method and apparatus for classifying a voice-recognized text. A specific embodiment of the method includes: acquiring a current interactive text of a voice query from a user; analyzing the current interactive text using a lexical analyzer to obtain a current lexical structure; determining whether the current lexical structure matches a template of a category in a classifier; and classifying, if the current lexical structure matches the template of the category in the classifier, the current interactive text corresponding to the current lexical structure into the category belonging to the matched template. The embodiment can fast classify texts, effectively reduce the magnitude of manually annotated texts, and improve the annotation efficiency in intelligent voice interaction services.

Abstract: An expired map data based anti-counterfeiting method, apparatus, storage medium and device. The method includes: acquiring currently expired map data; adding anti-counterfeiting content to the currently expired map data and storing the currently expired map data containing the anti-counterfeiting content; and creating and storing a current anti-counterfeiting map based on basic map data and the currently expired map data containing the anti-counterfeiting content. Using the anti-counterfeiting content added to the currently expired map data as the anti-counterfeiting map data, compared with using false data for anti-counterfeiting in the map data, increases the concealment of the anti-counterfeiting data in the anti-counterfeiting map and improves the anti-counterfeiting effect of the anti-counterfeiting map.
