Abstract: A method for data processing is provided. The method may include: preprocessing initial data to obtain preprocessed data; storing the preprocessed data; receiving a data request made through an application, the data request including information relating to a storage path of contents that are requested; in response to the data request, determining, by a nearby proxy of a first proxy cluster in a first region, whether the contents requested in the data request are cached locally; and in response to a determination that the contents are cached locally, providing, by the nearby proxy, the contents to the application; or in response to a determination that the contents are not cached locally, acquiring, by the nearby proxy, the contents based on the information relating to the storage path of the contents; and providing, by the nearby proxy, the contents to the application.

Abstract: A method for data management for an autonomous vehicle may include transmitting a polling request to a first server to obtain a task. The task may be a remote task request, and the task may be associated with obtaining, from the autonomous vehicle, data related to one or more subjects via a mobile network. The method may also include receiving the task from the first server based on the polling request. The method may also include obtaining the data based on the task. The method may also include transmitting the data to a second server via the mobile network.

Abstract: Some embodiments of the present disclosure provide a method for generating video mask information, a method for preventing occlusion from barrage, a server and a client. The method for generating video mask information comprises: identifying, for any video frame in the video data to be parsed, an area where a target object is located in the video frame; selecting a plurality of geometric figures to fit the area where the target object is located, to allow a combination of the plurality of geometric figures to cover the area where the target object is located; and generating the mask information of the video frame according to a fitting parameter of the plurality of geometric figures, and sending the mask information and data of the video frame to a client synchronously. Some embodiments of the present disclosure are adopted to avoid occlusion caused by the barrage information on the video image while the vast majority of the barrage information remains and reducing a bandwidth consumption of the client.

Abstract: Part of the present application provides a method, system and device for fitting a target object in a video frame. The method comprises: identifying a region where the target object is located in the video frame; selecting one or more geometric figures to fit the region where the target object is located, such that a combination of the one or more geometric figures covers the region where the target object is located; and generating a fitting parameter for each of the geometric figures according to a type of the geometric figure and a layout parameter of the geometric figure in the video frame, and taking a combination of the fitting parameters of respective geometric figures as a fitting parameter of the video frame. With the embodiments of the present application, the data amount after fitting is reduced, thereby improving efficiency of subsequent processes.

Abstract: A method for naming a pickup location may include obtaining a location pair associated with a user from a terminal, the location pair including a current location and a pickup location. The method may also include determining a first and a second preliminary POIs based on the location pair and a target POI database. The method may further include determining a feature of the first preliminary POI and a feature of the second preliminary POI. The method may also include obtaining a trained naming model for naming a pickup location and determining a first score for the first preliminary POI and a second score for the second preliminary POI. The method may further include determining a final POI based on the first score and the second score, and determining a name of the pickup location based on the final POI.

Abstract: A system includes at least one computer-readable storage medium including a set of instructions for determining target stations for a region in an on-demand service; and at least one processor in communication with the computer-readable storage medium. When executing the set of instructions, the at least one processor is directed to: obtain electronic signals encoding road information associated with a region and a plurality of service starting points of historical service orders associated with the region; operate logic circuits in the at least one processor to cluster the plurality of service starting points into a plurality of clusters based on the service starting points and the road information; operate the logic circuits in the at least one processor to determine one service starting point as a candidate point for each of the plurality of clusters based on a popularity score at the service starting point.

Abstract: The present disclosure relates to systems and methods for carpooling. The systems may perform the methods to receive a first intention for a first transportation service of a first subject from a first service requester at a first service intention time; identify an available service provider at the first service intention time; send the service provider a first time point to arrive at a pick-up location and a wait time to stop at the pick-up location before departing from the pick-up location; and send the first service requester a second time point to arrive at the pick-up location.

Abstract: A method for implementing parallel download applicable to a system supporting the download of chunked download content includes: acquiring download source information corresponding to download content, wherein the download source information comprises multiple content sources providing the download content, and the multiple content sources corresponds to multiple download servers respectively; dividing the download content into download content chunks according to the download source information; sending a download content chunk request to the multiple download servers corresponding to the multiple content sources respectively, and downloading the download content chunks from the multiple download servers in parallel. A download agent for implementing parallel download is provided. The method and download agent of the embodiments of the present invention may improve the download speed and robustness effectively. Therefore, object files with a large amount of data may be downloaded reliably and rapidly.

Abstract: A method and system for publication control of digital content for validating the rights information registered by a plurality of separate content providers. When receiving a digital content publication application from a content publication unit, a publication control unit queries whether rights information corresponding to the digital content to be published is stored in a rights publication unit, and if stored, allows the publication of the digital content and of a download address thereof. By messaging rights information in this centralized manner, it may be ensured that a content buyer can efficiently obtain the rights object distributed after the digital content is published.
