COMBO-SEG Model for Western_Armenian

Model Description

This is a Western_Armenian-language character-level segmentation model based on COMBO-SEG, an open-source text segmentation system. It performs:

• sentence segmentation
• tokenisation (including multi-word token detection)

The Western_Armenian model uses FacebookAI/xlm-roberta-base as its base encoder and is trained on UD_Western_Armenian-ArmTDP (UD v2.17).

Evaluation

Metric	Tokens	Words	Sentences
F1	99.94	97.62	99.78

Usage

Install the library from PyPI:

pip install combo-seg

from combo_seg import ComboSeg

# Load a pre-trained model
nlp = ComboSeg("Western_Armenian")

# Segment raw text — returns Document with hierarchy: Document -> Turn -> Sentence -> Token
doc = nlp("Արագ շագանակագոյն աղուէսը ծոյլ շան վրայէն կը ցատկէ։")

# Inspect results
for turn in doc.turns:
    for sentence in turn.sentences:
        print(f"Sentence: {sentence.text}")
        for token in sentence.tokens:
            if token.is_multi_word:
                print(f"  MWT: {token.text} -> {token.subwords}")
            else:
                print(f"  Token: {token.text}")

Or load directly from HuggingFace:

from combo_seg import ComboSeg

nlp = ComboSeg.from_pretrained("clarin-pl/combo-seg-xlm-roberta-base-western-armenian-armtdp-ud2.17")
doc = nlp("Արագ շագանակագոյն աղուէսը ծոյլ շան վրայէն կը ցատկէ։")
