实体描述分组   2019/4/16

实体描述分组排序 对于各组进行拓扑排序 属于同一个组（语义标签）的排序： 1、正向属性：按照BTC中实例化次数（流行度）排序 2、反向属性：如果存在相应的正向属性，直接跟在正向属性之后 3、其他反向属性，排在最后，按照其正向属性的流行度排序。 2019/4/16

在Spielberg导演的电影中，出品了k部电影以上的出品人有哪些？ 在上例中 {David， Walter}出品了2部电影以上 问题：对于一个关系(属性)p， wk : ≥k p, 找到k，对 p 到达的实体集合进行划分 基于信息熵的最佳分类 ≥k p属性选择

找到 { ≥k p} 建立Concept Lattice  nested line diagram 选择Top-K
