Abstract: Disclosed are interest tag determining method and device for accurately promoting information for users in a group based on interest tags of the group. This includes obtaining a group identifier and a corresponding group name, obtaining user identifiers corresponding to the group identifier and first user contents of the user identifiers, concatenating the first user contents of the user identifiers corresponding to the group identifier to obtain a first group content of the group identifier, calculating probabilities that the first group content is under the topic identifiers, and determining interest tags of the group identifier according to the probabilities that the first group content is under the topic identifiers and an association relationship between the topic identifiers and the interest tags that is determined through pre-training.

Abstract: This disclosure relates to a distance information display method in a virtual scene and a terminal. The method includes: obtaining location information of a target location point in the virtual scene; obtaining distance information according to the location information of the target location point; and displaying the distance information corresponding to an indication icon of the target location point in a scene picture of the virtual scene. According to the foregoing solution, in a virtual scene, for a target location point at which an indication icon exists in a scene picture of the virtual scene, the terminal may display information about a distance between a current controlled object and the target location point corresponding to the indication icon in the scene picture of the virtual scene.

Abstract: A method for controlling a terminal by voice includes: querying, by a first terminal installed with a first client, a second client on a second terminal about scene information. The scene information includes information of at least one operable object in at least one display interface of the second client. The method also includes: displaying, on the first client, a prompt message about voice recording, the prompt message being a reference for a user to issue a voice operation; recording voice to obtain first audio data in response to an operation on a voice recording control of the first client; transmitting the scene information and the first audio data to a server, the server being a back-end server of the second client; and transmitting, after a control instruction is returned by the server, the control instruction to the second client, the control instruction carrying information of a to-be-performed operable object.

Abstract: A GOA unit, a GOA circuit and a display panel are provided. The GOA unit includes a pull-up module, a pull-up holding module, a converting module, a pull-down holding module, and a pull-down module. Each module can be implemented with N-type TFTs. The GOA unit could generate a negative impulse waveform for internal feedback mechanism.

Abstract: A recycling device includes a main body, an input module, an identification module, a detection module, a packaging module, and a storage module. The input module includes at least one input port for depositing a waste product of one type. The identification module identifies the deposited waste product and determines whether the type of the deposited waste product matches the corresponding input port. The detection module detects a purity of the deposited waste product when the type of the deposited waste product matches the corresponding input port. The packaging module packages the deposited waste product when the purity of the deposited waste product is qualified. The storage module stores the deposited waste product.

Abstract: A server may divide a map into a grid comprising a plurality of cells, each of the cells corresponding to different geographic areas represented on the map. The server may determine geographic locations for a plurality of virtual props, respectively. The server may determine cells for the virtual props based on the geographic locations for placement of the virtual props. The server may obtain a current geographic location of a client. The server may identify a cell of the grid corresponding to the current geographic location of the client. The server may determine the identified cell is associated a virtual prop included in the virtual props. The server may allocate in response to the identified cell being associated with the virtual prop, the virtual prop to the client. The client receive prompt information indicative of the virtual prop being allocated to the client.

Abstract: The present disclosure describes methods, devices, and storage medium for recognizing a target object in a target image. The method including obtaining, by a device, an image recognition instruction, the image recognition instruction carrying object identification information used for indicating a target object in a target image. The device includes a memory storing instructions and a processor in communication with the memory. The method includes obtaining, by the device, an instruction feature vector matching the image recognition instruction; obtaining, by the device, an image feature vector set matching the target image, the image feature vector set comprising an ith image feature vector for indicating an image feature of the target image in an ith scale, and i being a positive integer; and recognizing, by the device, the target object from the target image according to the instruction feature vector and the image feature vector set.
