mòine¶

mòine is a Python and Rust library for romanization-aware string comparison. It implements Lattice Path Edit Distance (Kaji, 2023), a distance metric that compares strings through possible reading paths rather than only through visible surface characters.

>>> import moine
>>> moine.distance("moine", "モイニャ", lang="ja")
2
>>> moine.distance("もいにゃ", "モイニャ", lang="ja")
0
>>> moine.distance("weishiji", "威士忌", lang="zh")
0
>>> moine.distance("布納哈奔", "布納哈本", lang="zh")
0

What It Is For¶

mòine is useful for matching noisy Japanese or Chinese search/input strings, especially when surface forms differ but reading paths stay close.

• Japanese comparison uses UniDic-CWJ-derived reading artifacts.
• Chinese comparison uses CC-CEDICT-derived no-tone pinyin artifacts.
• Python APIs include distance, damerau_distance, ratio, partial_ratio, and cdist.
• Rust users can use the published crate and detailed API documentation on docs.rs.
