Abstract: The present disclosure provides a searching method and apparatus, a device and a non-volatile computer storage medium. According to embodiments of the present disclosure, it is possible to obtain a search intention according to the obtained query keyword, and then obtain at least one scenario detail according to the search intention, so that it is possible to output the at least one scenario detail. Since the same search intention might correspond to different scenario demands, directly providing the user with several scenario details corresponding to the search intention can effectively meet differentiated demands when the user uses the same query keyword to search under different scenarios.

Abstract: A query processing method. A server node parses a query request and generates a corresponding logical plan; judges the logical plan belonging to an OLAP scale query service or an OLTP scale query service; in response to judging that the logical plan belongs to the OLAP scale query service, segmenting the logical plan into logical subplans. A coordinator node generates a first physical plan corresponding to the logical plan, and feeds back the first physical plan to the server node. The server node assigns each of the logical subplans to the corresponding worker node according to the first physical plan. The worker node processes the corresponding logical subplan to obtain a query subresult, and reports the processing subresult layer by layer. The server node summarizes the received processing subresult, generates a final query result, and feeds back the final query result to a user.

Abstract: The disclosure provides a method for indoor localization, a related electronic device and a related storage medium. A first image position of a target feature point of a target object is obtained and an identifier of the target feature point is obtained based on a first indoor image. A 3D spatial position of the target feature point is obtained through retrieval based on the identifier of the target feature point. The 3D spatial position is pre-determined based on a second image position of the target feature point on a second indoor image, a posture of a camera for capturing the second indoor image, and a posture of the target object on the second indoor image. An indoor position of the user is determined based on the first image position of the target feature point and the 3D spatial position of the target feature point.

Abstract: The present disclosure provides a computer-implemented method for translating an image and a computer-implemented method for training an image translation model. In the computer-implemented method for translating an image, an image translation request carrying an original image is obtained. The original image is processed to generate a pre-translated image, a mask image and a deformation parameter. The original image is deformed based on the deformation parameter to obtain a deformed image. The deformed image, the pre-translated image and the mask image are merged to generate a target translated image.
