Abstract: According to a song recommendation method and apparatus, an electronic device, a storage medium, a computer program product and a computer program provided in embodiments of the present disclosure, a first page can be displayed firstly, and the first page includes a target song selected according to a song release date; then, in response to a trigger operation performed for the target song on the first page, the first page is switched to a second page of the selected target song. The song release date of the target song in the present embodiment is determined according to release information and auditory perception information of a song, and in this way, a real song release date of a song can be effectively identified, which in turn enables the target song shown on the first page to be selected based on the real song release date thereof.

Abstract: A melody information processing method is described. A piece of Musical Instrument Digital Interface (MIDI) data corresponding to a song is received, a song identifier of the song is obtained, first melody information is generated according to the MIDI data, and the first melody information is stored in association with the song identifier in a melody database. Moreover, a user unaccompanied-singing audio data set that is uploaded from a user terminal is received, second melody information corresponding to the song identifier is extracted according to the user unaccompanied-singing audio data set, and the second melody information is stored in association with the song identifier in the melody database.

Abstract: A voice data processing method and apparatus are provided. The method includes obtaining an I-Vector vector of each of voice samples, and determining a target seed sample in the voice samples. A first cosine distance is calculated between an I-Vector vector of the target seed sample and an I-Vector vector of a target remaining voice sample, where the target remaining voice sample is a voice sample other than the target seed sample in the voice samples. A target voice sample is filtered from the voice samples or the target remaining voice sample according to the first cosine distance, to obtain a target voice sample whose first cosine distance is greater than a first threshold.

Abstract: Methods, systems, and computer-readable storage media for event-triggered reassignment of time-limited resources. Implementations include actions of receiving an event indicator, determining a particular demand and associated particular time-limited resources based on the event indicator, identifying, for the particular demand, one or more first candidate demands in an assignment plan, the assignment plan including a plurality of demands associated with a plurality of time-limited resources, each first candidate demand and associated time-limited resources satisfying one or more constraints defined by the particular demand and associated particular time-limited resources, determining whether at least one of the first candidate demands has not been processed, and performing an action based on a result of determining whether at least one of the first candidate demands has not been processed.
