Lexikanon
Korean and English tokenizers, text normalizers, and stopword lists. Lexikanon is a plain Python library; it also ships HyFI 2.0 config groups, so the same tokenizers can be selected and run from HyFI workflows.
Lexikanon 1.0 drops the HyFI 1.x API. Pin lexikanon<1 to keep it.
Install
uv add lexikanon # or: pip install lexikanon
pip install 'lexikanon[datasets]' # tokenize_dataset / extract_tokens on datasets.Dataset
pip install 'lexikanon[similarity]' # find_similar_docs_by_clustering
Python 3.11 or newer. Korean morphological analysis uses MeCab through eKoNLPy (fugashi and mecab-ko-dic wheels). On Python 3.15, fugashi builds from source and needs the MeCab library (apt-get install libmecab-dev or brew install mecab).
Use it as a library
from lexikanon.normalizers import Normalizer
from lexikanon.tokenizers import MecabTokenizer
tokenizer = MecabTokenizer(noun_postags=["NNG", "NNP"])
tokenizer("금통위는 물가안정과 금리정책을 밝혔다.")
# ['금통위/NNG', '는/JX', '물가/NNG', '안정/NNG', '과/JC', ...]
tokenizer.nouns("금통위는 물가안정과 금리정책을 밝혔다.")
Normalizer(hanja2hangle=True)("今年에도 持續하고 있다")
# '금년에도 지속하고 있다'
Importing lexikanon never imports HyFI.
Use it from HyFI
Installing lexikanon registers its config groups through the hyfi.plugins entry point:
| group | options |
|---|---|
tokenizer |
default, simple, mecab, nltk, nltk_universal |
normalizer |
default, formal_ko, informal_ko, formal_en, formal_en_parantheses |
stopwords |
default |
workflow |
lexikanon_tokenize_text, lexikanon_tokenize_dataset, lexikanon_find_similar_docs |
hyfi plugins
hyfi run workflow=lexikanon_tokenize_text tokenizer=mecab
import hyfi
tokenizer = hyfi.instantiate(hyfi.compose_group("tokenizer", "mecab"))
See Usage for workflow steps and presets.
