English | 中文
文本相似度：字符 shingle 的 Jaccard 与归一化编辑距离。
安装
pip install zysl
用法
from zysl import jaccard, levenshtein, similarity
jaccard("hello", "hallo") # 0.3333...
levenshtein("kitten", "sitting") # 3
similarity("kitten", "sitting") # 0.5714...
说明
jaccard 按 n-gram 集合求交并比，对词序敏感度低；levenshtein 用两行滚动数组，长文本也只占 O(n) 内存；similarity 把编辑距离归一化到 0~1，两条都空视为完全相似。

English
Text similarity: Jaccard over character shingles plus normalized edit distance.
Install
pip install zysl
Usage
from zysl import jaccard, levenshtein, similarity
jaccard("hello", "hallo") # 0.3333...
levenshtein("kitten", "sitting") # 3
similarity("kitten", "sitting") # 0.5714...
Notes
jaccard compares n-gram sets, so it tolerates reordering; levenshtein keeps two rolling rows, so memory stays O(n) on long input; similarity normalizes the distance to 0..1 and treats two empty strings as identical.
