Presented herein are systems, methods, and datasets for automatically and precisely generating highlight or summary videos of content. In one or more embodiments, the inputs comprise a text (e.g., an article) of the key event(s) (e.g., a goal, a player action, etc.) in an activity (e.g., a game, a concert, etc.) and a video or videos of the activity. In one or more embodiments, the output is a short video of an event or events in the text, in which the video may include commentary about the highlighted events and/or other audio (e.g., music), which may also be automatically synthesized.

Generating highlight video from video and text inputs

Embodiments of the present disclosure provide a method and apparatus for aligning a paragraph and a video. The method may include: acquiring a commentary and a candidate material resource set corresponding to the commentary, a candidate material resource being a video or an image; acquiring a matching degree between each paragraph in the commentary and each candidate material resource in the candidate material resource set; and determining a candidate material resource sequence corresponding to the each paragraph in the commentary based on the matching degrees between the paragraphs in the commentary and the candidate material resources, playing durations of the candidate material resources and text lengths of the paragraphs in the commentary, an image playing duration being a preset image playing duration.

Method and apparatus for aligning paragraph and video

Embodiments of the present disclosure provide a method and apparatus for generating a commentary. The method may include: acquiring at least one news cluster composed of pieces of news generated within a first preset time length, the pieces of news in the news cluster direct to a given news event; determining a target news cluster based on the at least one news cluster; determining, for each piece of news in the target news cluster, a score of being suitable for generating a commentary for the piece of news; and generating, based on a piece of target news, a commentary for the target news cluster, where the piece of target news is a piece of news having a highest score of being suitable for generating a commentary in the target news cluster.

Method and apparatus for generating commentary

A system and method for enabling users to operate multiple blockchain (or distributed ledger) nodes efficiently, at a much lower cost, etc. For example, when one blockchain starts to take up resources, the system can automatically adjust by looking at the application container layer to see if it is possible to shift resources. It can also shift resources at the server layer to adjust for computation and memory resources to, for example, increase efficiency. It may also share storage for nodes that share the same blockchain to, for example, increase efficiency. The system can also identify tokens that are more efficient to stake, and to shift tokens from one blockchain to another for staking reward efficiencies, etc. It may also deploy one node to another geographic region to increase decentralization, as well as adjust rewards and commissions to provide incentives to boost decentralization as well.

Method and system for heterogeneous blockchain service management

Embodiments of the present disclosure provide a method and apparatus for generating a video. The method may include: receiving a query text inputted by a user; querying a material resource set related to the query text, material resources being images, videos, or audios; presenting the material resource set; determining a material resource sequence, in response to receiving a selecting operation and a ranking operation of the user on the material resources in the presented material resource set; and generating the video based on the material resource sequence.

Method and apparatus for generating video

Embodiments of the present disclosure provide a method and apparatus for generating a video. The method may include: determining a commentary of a target news cluster, each piece of news in the target news cluster being specific to a given news event; generating a voice corresponding to each paragraph in the commentary using a speech synthesis technology; determining a candidate material resource set corresponding to the commentary based on a video and an image included in the target news cluster, the candidate material resource being a video or image; determining a candidate material resource sequence corresponding to the each paragraph in the commentary; and generating a video corresponding to the commentary based on the voice corresponding to the each paragraph in the commentary and the candidate material resource sequence.

Embodiments of the present disclosure provide a method and apparatus for generating information. The method may include: determining at least one video segment obtained by semantically segmenting videos included in a target news cluster as a target video set, where respective pieces of news in the target news cluster directs to a given news event; determining a commentary for the target news cluster; determining, based on the target video set and a target image set, a candidate material resource set corresponding to the commentary, where the target image set is composed of respective images included in the target news cluster; and for each paragraph in the commentary, determining degrees of matching between the paragraph and candidate material resources in the candidate material resource set.

Method and apparatus for generating information

A method and apparatus for adjusting a parameter are provided. The method may include: acquiring a current value of at least one parameter which is in a process of generating a video corresponding to a commentary of the news cluster based on a news cluster; determining a video evaluation score of the video which is generated based on the news cluster and according to the current value of the at least one parameter; performing feature extraction on the current value of the at least one parameter to obtain a feature representation; inputting the feature representation and the determined video evaluation score into a pre-trained evaluation network to obtain a predicted video evaluation score; inputting the feature representation and the predicted video evaluation score into a pre-trained operation network, to obtain current operation information; and adjusting the current value of the at least one parameter based on the current operation information.
