Installation

pip install meitei-senter

Optional: spaCy Backend (for higher accuracy)

pip install meitei-senter[spacy]

Quick Start

Python API

from meitei_senter import MeiteiSentenceSplitter

# Initialize the splitter
splitter = MeiteiSentenceSplitter()

# Split text into sentences
text = "ꯆꯦꯔꯣꯀꯤ ꯑꯁꯤ ꯑꯣꯀ꯭ꯂꯥꯍꯣꯃꯥꯒꯤ ꯁꯍꯔꯅꯤ ꯫ ꯃꯁꯤ ꯌꯥꯝꯅ ꯆꯥꯎꯏ ꯫"
sentences = splitter.split_sentences(text)

for i, sent in enumerate(sentences, 1):
    print(f"{i}. {sent}")

Output:

1. ꯆꯦꯔꯣꯀꯤ ꯑꯁꯤ ꯑꯣꯀ꯭ꯂꯥꯍꯣꯃꯥꯒꯤ ꯁꯍꯔꯅꯤ ꯫
2. ꯃꯁꯤ ꯌꯥꯝꯅ ꯆꯥꯎꯏ ꯫

Command Line

# Interactive mode
meitei-senter --interactive

# Direct text input
meitei-senter --text "ꯆꯦꯔꯣꯀꯤ ꯑꯁꯤ ꯑꯣꯀ꯭ꯂꯥꯍꯣꯃꯥꯒꯤ ꯁꯍꯔꯅꯤ ꯫ ꯃꯁꯤ ꯌꯥꯝꯅ ꯆꯥꯎꯏ ꯫"

# Show version
meitei-senter --version

Advanced Usage

Using the Convenient Loader

from meitei_senter import load_splitter

# Load with default (delimiter-based) backend
splitter = load_splitter()

# Or with spaCy backend (requires spacy extra)
splitter = load_splitter(use_spacy=True)

sentences = splitter.split_sentences("Your Meitei text here ꯫")

Using Neural Network Mode

from meitei_senter import MeiteiSentenceSplitter

# Enable neural mode for context-aware splitting
splitter = MeiteiSentenceSplitter(use_neural=True)
sentences = splitter.split_sentences(text)

Direct Callable Interface

from meitei_senter import MeiteiSentenceSplitter

splitter = MeiteiSentenceSplitter()

# Call splitter directly
sentences = splitter("ꯆꯦꯔꯣꯀꯤ ꯑꯁꯤ... ꯫ ꯃꯁꯤ ꯌꯥꯝꯅ ꯆꯥꯎꯏ ꯫")

With spaCy (Custom Tokenizer)

import spacy
import os
from meitei_senter import MeiteiTokenizer, get_model_path

# Get path to bundled model
model_path = os.path.join(get_model_path(), 'meitei_tokenizer.model')

# Create blank spaCy model with custom tokenizer
nlp = spacy.blank("xx")
nlp.tokenizer = MeiteiTokenizer(model_path, nlp.vocab)

doc = nlp("ꯆꯦꯔꯣꯀꯤ ꯑꯁꯤ ꯑꯣꯀ꯭ꯂꯥꯍꯣꯃꯥꯒꯤ ꯁꯍꯔꯅꯤ ꯫")
print([token.text for token in doc])
# Output: ['ꯆꯦ', 'ꯔꯣ', 'ꯀꯤ', 'ꯑꯁꯤ', 'ꯑꯣꯀ꯭ꯂꯥꯍꯣꯃꯥ', 'ꯒꯤ', 'ꯁꯍꯔ', 'ꯅꯤ', '꯫']

API Reference

MeiteiSentenceSplitter

Main class for sentence splitting.

MeiteiSentenceSplitter(
    pth_path: str = None,      # Path to PyTorch model
    spm_path: str = None,      # Path to SentencePiece model
    config_path: str = None,   # Path to config JSON
    use_neural: bool = False   # Enable neural network mode
)

Methods:

Method	Description
split_sentences(text)	Split text into list of sentences
tokenize(text)	Tokenize text into pieces and IDs
__call__(text)	Direct callable interface

MeiteiTokenizer

spaCy-compatible tokenizer using SentencePiece.

MeiteiTokenizer(model_path: str, vocab: spacy.Vocab)

load_splitter

Convenience function to load a pre-configured splitter.

load_splitter(use_spacy: bool = False)
