Tajik Morphological Corpus

A morphological corpus of the Tajik language containing word forms, lemmas, grammatical tags, and frequency information.

📖 Description

The dataset includes 3,609 unique word forms (after deduplication) with:

• word form (word)
• lemma (lemma)
• grammatical tags (grammar), separated by commas and a vertical bar for alternative analyses
• frequency (freq) – number of occurrences in the original corpus

🚀 Usage example

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("TajikNLPWorld/TajikMorphCorpus")

# Access the train split
train = dataset["train"]

# Find all nouns (tag contains "N")
nouns = train.filter(lambda x: "N" in x["grammar"])

# Top 10 most frequent words
top_words = train.to_pandas().groupby("word")["freq"].sum().nlargest(10)

# Iterate through records
for record in train:
    print(record["word"], record["lemma"], record["grammar"], record["freq"])

🔬 Potential applications

• Morphological analysis of Tajik
• Training part‑of‑speech taggers
• Linguistic research on grammatical categories
• Creating dictionaries and teaching materials
