因为中国出生缺陷发生呈快速增长的趋势,研究人员没有条件研究发生在所有城市的所有出生缺陷案例。为了平衡研究的成本与效率,有必要选择“重要”的城市和“重要”的出生缺陷作为研究对象。介绍了BDRank,用于对出生缺陷和出生缺陷发生的城市排序。与PageRank不同,BDRank能够处理由多种对象组成的系统。更重要的是,BDRank能够有效使用研究人员的先验知识。实验使用了中国1987-1989年的出生缺陷数据,实验表明:和出生缺陷研究人员使用的现有方法相比,BDRank具有更好的排序精度。
Because of the rapid growth of birth defects in China, researchers have not been able to examine all cases of birth defects that occur in all cities. In order to balance the cost and efficiency of the research, it is necessary to choose the city of “important ” and “important ” birth defects as the research object. BDRank was introduced to rank the cities where birth defects and birth defects occur. Unlike PageRank, BDRank is able to handle a system of multiple objects. More importantly, BDRank can effectively use the researcher’s prior knowledge. Experiments used birth defect data from 1987 to 1989 in China. Experiments show that BDRank has better sorting accuracy than existing methods used by birth defect researchers.
