# Sindhi Open Lexicon Master Dataset

**Publisher:** [SindhiLanguage.org](https://sindhilanguage.org/)  
**Prepared and curated by:** Amar Fayaz Buriro (امر فياض ٻرڙو)  
**Version:** 1.0 — Generated: May 2026

---

## 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

```python
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)]
```

```python
# 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))
```

```python
# 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.
