labelled tree meaning in English

标记树, 标定树

When the constraint of unique labeling is removed , the ordered labeled tree becomes the objective
当取消了标号唯一性限定后，论文解决了有序标号树中的模式发现问题。
The algorithm transforms the traditional tree - to - tree correction into the comparing of the key trees , which are substantially label trees without duplicate paths . thus , the algorithm achieves high efficiency with the complexity of o ( n ) , where n is the total number of nodes in the trees , which is significant to the large scaled applications
为适应大规模应用的需要，本文提出了直接利用特征路径进行文档比较的kf - diff +算法，同时适于有序和无序两种模式，在时间复杂度上从先前的o ( nlogn )提高到o ( n ) ，更加适合internet规模的应用。
