  • Systems and methods for parent-child relationship determination for points of interest
    Patent number: 11003730
    Abstract: The present disclosure relates to systems and methods for determining parent-child relationships. The systems may obtain a first location name of a first point of interest (POI); perform a word segmentation operation on the first location to obtain a plurality of portions of the first location name; determine a first portion from the plurality of portions by comparing to a first portion name database, the first portion indicating that the first POI is a child POI; and determine a second POI based on a second portion of the first location name and that the second POI is a parent POI of the first POI.
    Type: Grant
    Filed: November 24, 2020
    Date of Patent: May 11, 2021
    Assignee: BEIJING DIDI INFINITY TECHNOLOGY AND DEVELOPMENT CO., LTD.

  • Vascular endothelial cell growth inhibitor, VEGI-192a
    Patent number: 7750133
    Abstract: This invention discloses two new VEGI isoforms named VEGI-192a and VEGI-192b consisting of 192 amino acid residues. These isoforms show endothelial cell-specific expression and share a C-terminal 151-residues segment with the previously described VEGI-174 and VEGI-251. Methods of using these isoforms of VEGI in diagnosing, screening agonist and antagonist of the isoforms, and treating various angiogenesis-related diseases are also disclosed.
