git clone https://github.com/jacksonllee/wordseg.git
cd wordseg
pip install -e ".[dev]"

Usage
wordseg implements a word segmentation model as a Python class.
An instantiated model class object has the following methods
(emulating the scikit-learn-styled API for machine learning):

fit: Train the model with segmented sentences.
predict: Predict the segmented sentences from unsegmented sentences.

The implemented model classes are as follows:

RandomSegmenter:
Segmentation is predicted at random at each potential word
boundary independently for some given probability. No training is required.
LongestStringMatching:
This model constructs predicted words by moving
from left to right along an unsegmented sentence and
finding the longest matching words, constrained by a maximum word length parameter.

Sample code snippet:
from src.wordseg import LongestStringMatching

# Initialize a model.
model = LongestStringMatching(max_word_length=4)

# Train the model.
# `fit` takes an iterable of segmented sentences (a tuple or list of strings).
model.fit(
[
("this", "is", "a", "sentence"),
("that", "is", "not", "a", "sentence"),
]
)

# Make some predictions; `predict` gives a generator, which is materialized by list() here.
list(model.predict(["thatisadog", "thisisnotacat"]))
# [['that', 'is', 'a', 'd', 'o', 'g'], ['this', 'is', 'not', 'a', 'c', 'a', 't']]
# We can't get 'dog' and 'cat' because they aren't in the training data.
