Tajik Unified Morphological Corpus

Author: Arabov Mullosharaf Kurbonovich

Morphological corpus of the Tajik language, combining data from tajik-corpus.org.
Contains wordforms, lemmas, grammatical tags, and frequency information.

📖 Description

The dataset includes 200,144 entries (wordforms with their morphological analyses) with:

• wordform (word)
• lemma (base form)
• grammar tag (grammar) - combines POS and grammatical features
• part of speech (pos)
• grammatical features (features)
• gloss (short meaning)
• English translation (trans_en)
• Russian translation (trans_ru)
• raw grammar tag (gramm_raw)
• frequency (freq) - number of occurrences in the corpus

🚀 Usage Example

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("TajikNLPWorld/TajikUnifiedCorpus")
train = dataset["train"]

# Filter nouns
nouns = train.filter(lambda x: x["pos"] == "N")

# Filter verbs in past tense
verbs_past = train.filter(lambda x: "past" in x["features"] if x["features"] else False)

# Top 10 most frequent words
import pandas as pd
df = train.to_pandas()
top_words = df.groupby("word")["freq"].sum().nlargest(10)
print(top_words)

# Iterate through records
for record in train.select(range(5)):
    print(f"{record['word']} -> {record['lemma']} ({record['grammar']})")
