  • Publication number: 20230098491
    Abstract: The invention provide an assessment method and device for infectious disease transmission, computer equipment and storage medium. The method comprises: obtaining respective target track data corresponding to assessment objects within a preset area in a first time slice; determining a matching subarea to which each assessment object matches in the first time slice based on the target track data; taking at least one of the plurality of subareas as a target subarea, and assessing an assessment object within the target subarea based on an infectious disease model to determine a transmission trend of an infectious disease for the assessment object within the preset area in the first time slice; and taking a next time slice as the first time slice, and re-performing the above steps until end of the target time period to determine a transmission trend of the infectious disease among the assessment objects during the target time period.

  • Publication number: 20210312326
    Abstract: A travel prediction method, apparatus, device, and storage medium.
    Type: Application
    Filed: July 17, 2020
    Publication date: October 7, 2021
    Inventors: Xuan Song, Zipei Fan, Quanjun Chen, Renhe Jiang, Zekun Cai, Ryosuke Shibasaki
  • Publication number: 20210304900
    Abstract: A method and apparatus for predicting transmission of an infectious disease, a computer apparatus, and a storage medium. The method includes determining one or more objects to be predicted, matching in a historical travel path database for a corresponding predicted path of each of the one or more objects to be predicted, and determining a transmission trend of the infectious disease in the one or more objects to be predicted based on the predicted travel paths. The predicted travel path of each object to be predicted is matched in the historical travel path database thus achieving the effect of reducing the computation amount of obtaining the predicted travel path.
