Abstract: An audio file playing method and an apparatus are disclosed and are used to: when an audio file is played, expand a quantity of audio channel signals in the audio file and improve a playing effect of the audio file. The method is as follows: after the audio file is obtained, determining, whether the audio file includes an audio channel signal that can be played by the mobile device; if the audio file includes the audio channel signal that can be played by the mobile device, directly playing the audio channel signal. Therefore, when multiple mobile devices are used to play a same audio file, the mobile devices can avoid performing a same operation, thereby increasing a quantity of audio channels of the audio file, expanding a sound field of the audio file, and improving a playing effect of the audio file.

Abstract: The invention provides a display device for head mounting, in particular a Maxwellian display device, with an enlarged eye-box. The display device includes a light source emitting light beams for forming an image, an optical system for guiding the light beams to a beam forming element. The beam forming element is configured to converge each of multiple sets of the light beams into a different point of convergence, for example on an exit pupil of the display device. Each point of convergence is a convergent viewing point for a user. The eye-box is thus enlarged.

Abstract: The present invention discloses a method and an apparatus for querying data in cross-shard databases. The method includes: receiving a query request; querying statistics information of respective shard databases in which two tables used in an association operation are located; sending, according to the statistics information and the query condition, a driving table query request to a shard database in which a driving table is located, and receiving a first query result set returned by the shard database in which the driving table is located; deduplicating association field values in the first query result set, and sending a result set delivery request and deduplicated association field values to a shard database in which the non-driving table is located; and sending a non-driving table query request to the shard database; and receiving a second query result set returned by the shard database. Efficiency of querying data in cross-shard databases is improved.

Abstract: An artificial intelligence-based semantic recognition method, apparatus, and device. In the artificial intelligence-based semantic recognition method, a pre-trained semantic recognition model is trained by using a training corpus configured by a developer on a model training platform such as a Bot platform and a negative corpus provided on the model training platform, where the negative corpus is extracted by mapping an encoding value of the training corpus to a negative corpus set. Therefore, the negative corpus is extracted based on the encoding value of the training corpus, and a randomized method for generating the negative corpus is changed into a stable method.
