In order to improve efficiency, we first choose the entities with closest label to construct the mapping space, then we propagate the mapping pair with higher similarity, namely compose mapping pair in entities related with them and add to mapping space.

• 为了提高映射效率，使用多种策略构建候选映射空间而不是直接生成所有可能的候选映射对，首先从具有相近标签的实体开始构造，然后对其中相似度较高的实体进行繁殖，即把与它们相关的实体组成映射对添加到候选映射空间。
