🐍 python-vibrato 🎤

Vibrato is a fast implementation of tokenization (or morphological analysis) based on the Viterbi algorithm. This is a Python wrapper for Vibrato.

Installation

Install pre-built package from PyPI

Run the following command:

$ pip install vibrato

Build from source

You need to install the Rust compiler following the documentation beforehand. daachorse uses pyproject.toml, so you also need to upgrade pip to version 19 or later.

$ pip install --upgrade pip

After setting up the environment, you can install daachorse as follows:

$ pip install git+https://github.com/daac-tools/python-vibrato

Example Usage

python-vibrato does not contain model files. To perform tokenization, follow the document of Vibrato to download distribution models or train your own models beforehand.

Check the version number as shown below to use compatible models:

import vibrato
vibrato.VIBRATO_VERSION
#=> "0.3.3"

Examples:

import vibrato

with open('path/to/system.dic', 'rb') as fp:
    dict_data = fp.read()
tokenizer = vibrato.Vibrato(dict_data)

tokens = tokenizer.tokenize('社長は火星猫だ')

len(tokens)
#=> 5

list(tokens)
#=> [Token { surface: "社長", feature: "名詞,一般,*,*,*,*,社長,シャチョウ,シャチョー,," },
#    Token { surface: "は", feature: "助詞,係助詞,*,*,*,*,は,ハ,ワ,," },
#    Token { surface: "火星", feature: "名詞,一般,*,*,*,*,火星,カセイ,カセイ,," },
#    Token { surface: "猫", feature: "名詞,一般,*,*,*,*,猫,ネコ,ネコ,," },
#    Token { surface: "だ", feature: "助動詞,*,*,*,特殊・ダ,基本形,だ,ダ,ダ,," }]

tokens[0].surface()
#=> '社長'

tokens[0].feature()
#=> '名詞,一般,*,*,*,*,社長,シャチョウ,シャチョー,,'

tokens[0].start()
#=> 0

tokens[0].end()
#=> 2
