Dataset Summary

This is a developer-ready and AI-ready master lexical dataset for the Sindhi language — one of the largest structured Sindhi datasets available for AI and NLP use.

It contains 223,342 lexical entries drawn from multiple Sindhi dictionary and terminology sources, normalized into CSV, JSONL, and SQLite formats. Sindhi is a historically rich but low-resource language in AI; this dataset aims to help change that.

Supported Tasks

• Language Modeling — pre-training or fine-tuning Sindhi LLMs
• Named Entity Recognition — tagged domain and part-of-speech fields
• Feature Extraction — normalized word and definition fields
• Dictionary / Search Applications — direct lookup use
• Machine Translation — bidirectional entries (English↔Sindhi, Arabic↔Sindhi, Hindi↔Sindhi)
• OCR Post-correction — normalized forms aid Sindhi OCR pipelines

Usage

import pandas as pd

# Load full CSV
df = pd.read_csv("data/sindhi_open_lexicon_master_223342.csv")
print(df.shape)        # (223342, 12)
print(df.columns.tolist())

# Filter by source dictionary
pure_sindhi = df[df["source_dictionary"] == "جامع سنڌي لغات"]

# Filter by language direction
en_sd = df[df["language_direction"] == "English → Sindhi"]

# Search for a word
results = df[df["normalized_word"].str.contains("ڪتاب", na=False)]

# Load JSONL
import json

entries = []
with open("data/sindhi_open_lexicon_master_223342.jsonl", "r", encoding="utf-8") as f:
    for line in f:
        entries.append(json.loads(line))

# Query SQLite
import sqlite3

conn = sqlite3.connect("sqlite/sindhi_open_lexicon_master_223342.sqlite")
cur = conn.cursor()
cur.execute("SELECT word, definition FROM lexicon WHERE source_dictionary = 'جامع سنڌي لغات' LIMIT 10")
for row in cur.fetchall():
    print(row)

Use Cases

• Sindhi language applications and chatbots
• AI and NLP model training and fine-tuning
• Large Language Model (LLM) vocabulary expansion
• Search, dictionary, and lexicon portals
• Educational and linguistic research
• OCR and spell-checking tools

---

Notes

• The dataset preserves source-level attribution for full transparency.
• Some entries may have incomplete part_of_speech or domain fields because the original dictionaries differ in structure.
• All text is UTF-8 encoded with right-to-left Sindhi script.
• The SQLite file is recommended for developers who need fast lookup queries.
