Abstract: A method of explaining why an item has been recommended to a user comprises determining a value for the preference of the user for the recommended item based on data relating to the user and the item. This may be in the form of an interaction score. The user data is then modified to reduce the determined preference value such that the recommended item would not be recommended to the user. The modified user data is then used to determine preference values for items with which the user has interacted. These will be different from previously determined preference values based on the unmodified user data. From these preference values it is then possible to identify one or more items with which the user has interacted, for which the determined preference values differ most from previously determined preference values. It can be concluded that the interaction of the user with these identified item(s) is the antecedent for the recommended item being recommended.

Abstract: Embodiments provide a method and an apparatus for determining speech similarity, and a program product, which relate to speech technology. The method includes: playing exemplary audio, and acquiring evaluation audio of a user, where the exemplary audio is audio of specified content that is read by using a specified language; acquiring a standard pronunciation feature corresponding to the exemplary audio, and extracting, from the evaluation audio, an evaluation pronunciation feature corresponding to the standard pronunciation feature, where the standard pronunciation feature is used to reflect a specific pronunciation of the specified content in the specified language; and determining a feature difference between the standard pronunciation feature and the evaluation pronunciation feature, and determining similarity between the evaluation audio and the exemplary audio according to the feature difference. In the scheme of the present application, the evaluation pronunciation feature corresponding to the standard pronunciation feature corresponding to the exemplary audio can be extracted from the evaluation audio, thereby achieving relatively small volume of a module functioned with similarity analysis of follow-up reading.

Abstract: A production method and device for multimedia works, and a computer-readable storage medium. The method comprises: acquiring a target audio and at least one piece of multimedia information, calculating the degree of match between the target audio and the multimedia information, sorting multimedia information on the basis of the degree of match in a descending order, assigning top-ranking multimedia information as target multimedia information; calculating the image quality of each image in the target multimedia information, sorting every image of the target multimedia information on the basis of image quality in a descending order, assigning the top-ranking images as target images; and synthesizing a multimedia work on the basis of the target images and the target audio. The method allows the acquisition of high-definition multimedia works in which the video content and background music match with each other, and reduces the time costs and costs of learning that a user spends on video editing.

Abstract: A mechanism for processing video data is disclosed. An essential property (EssentialProperty) of a Dynamic Adaptive Streaming over Hypertext transfer protocol (DASH) representation is determined (4202). The EssentialProperty indicates that the representation is an external stream representation (ESR). A conversion is performed between a visual media data and a media presentation based on the based on the ESR (4204).

Abstract: A mechanism for processing video data is disclosed. Information in a sequence parameter set (SPS) in a versatile video coding (VVC) elementary stream is determined. A rule specifies a number of units in a tick (num_units_in_tick) and a time scale (time_scale), when present in the SPS, shall not change between video sequences in the VVC elementary stream. A conversion is performed between a visual media data and a media data file based on the SPS.
