Abstract: The present disclosure discloses a navigation method, a device, and a medium. The method includes: planning candidate routes based on a start position and an end position of a user, and obtaining a sequence of candidate road sections in each candidate route; matching each candidate road section in the sequence of candidate road sections in each candidate route with an association relationship between an actual road section and actual road auxiliary information, to obtain a sequence of auxiliary information of each candidate route; and sorting the auxiliary information in the sequence of auxiliary information of each candidate route to obtain a sorted result corresponding each candidate route, and selecting target road auxiliary information from the sequence of auxiliary information of each candidate route based on the sorted result, so as to select a target route from the candidate routes based on the target road auxiliary information.

Abstract: Provided are a query rewriting method and apparatus, a device and a storage medium, relating to the technical field of data processing and, in particular, to technical fields including artificial intelligence, speech technology, intelligent search and deep learning. The solution includes, in response to a query rewriting request, extracting at least one of context information of an original query and intention information of the original query; and determining a new query based on a machine vocabulary collection and the at least one of the context information and the intention information. The understanding degree to the new query by a machine is greater than the understanding degree to the original query by the machine.

Abstract: A method, an apparatus, an electronic device and a storage medium for broadcasting a voice are provided. The method may include: sending a voice broadcast request to a server, where the voice broadcast request includes at least one of scenario information, user information or voice packet setting information; receiving a voice broadcast instruction corresponding to the voice broadcast request returned by the server; and acquiring a personalized voice packet corresponding to the voice broadcast instruction in a local database and broadcasting the personalized voice packet.

Abstract: The present application discloses a method and apparatus for guiding a voice-packet recording function, a device and a computer storage medium, and relates to the field of big data. An implementation includes identifying a target user with a voice-packet recording demand using historical map usage behaviors of map users; and identifying a scenario where the target user uses a client terminal, and if the scenario conforms to a voice-packet recording scenario, sending first guidance information of the voice-packet recording function to the client terminal. With the present application, accurate guidance of the voice-packet recording function is realized, and excessive disturbance in the user is reduced.
