Abstract: A personalized comment recommendation method based on a link prediction model of a graph bidirectional aggregation network. In a user-comment bipartite graph, comment features are aggregated into a user feature. A social network is used to fuse a neighbor feature of a user to obtain an embedding representation of the user. The embedding representation of the user is aggregated into a comment after an original feature of the user is removed, and the embedding representation of the user is adjusted based on a difference before and after comment aggregation. On this basis, a forwarding network is used to calculate a score of an edge based on an inner product of user node features at both ends of the edge, and finally make a recommendation based on the score. Furthermore, a recommendation system converts a comment recommendation task into a link prediction task between users in a small range.

Abstract: A method and an apparatus for processing a virtual reality movie. The method includes acquiring road-related features of road segments of a travel route; and providing at least one video clip matching the road-related features of the road segments of the travel route, as video clips for playing on the road segments.

Abstract: A method, a user terminal, and an electric vehicle are provided for updating a system for the electric vehicle. According to an example of the method, it is determined whether an electric vehicle is in use when receiving a system update operation instruction. A system update function is disabled when determining that the electric vehicle currently is in use. A system update is performed on the electric vehicle in response to the operation instruction when determining that the electric vehicle currently is in a standby status.
