  • Publication number: 20230259567
    Abstract: This application discloses a data processing method performed by a computing device. The method includes: acquiring a search keyword of a user, and determining a plurality of target keywords related to the search keyword. After the plurality of keywords are determined, the search keyword and the plurality of target keywords may further be displayed. When the search keyword and the plurality of target keywords are displayed, the plurality of target keywords are distributed on a periphery of a circle with the search keyword as a center in a dispersed manner to achieve a more convenient and intuitive effect. By using this solution, the plurality of target keywords related to the search keyword can be displayed for the user instead of directly providing the user with search results corresponding to the search keyword, and the user obtains the plurality of target keywords through analysis according to the search results.

  • Patent number: 10657143
    Abstract: Attribute information of a pending data handling process to be performed is identified. Historical data handling processes for a same application scenario as the pending data handling process are identified based on the attribute information. A time that each identified historical data handling process is performed and methods used to perform the identified historical data handling processes are also identified. A weighting coefficient for each identified historical data handling process is determined. Weighted identified historical data handling processes are calculated by applying the weight coefficient to each identified historical data handling process. A recommended weight for each method used to perform the identified historical data handling processes is determined by combining weighted identified historical data handling processes that use the same method. A method that has the highest recommended weight to perform the pending data handling process is recommended.
