nlp-engine-yuvraj 0.1.1

High-performance streaming NLP dataset ingestion engine

NLP Dataset Engine

A high-performance streaming ingestion engine for terabyte-scale NLP datasets. Built for GSoC 2026 preparation.

User Installation

pip install nlp-engine-yuvraj

Features

• Lazy Loading: Processes datasets larger than RAM using Python generators.
• Auto-Validation: Automatically drops empty or short text records.
• Observability: Provides detailed statistical reports on data quality.
• CLI Interface: simple command-line usage.

Installation

# Clone the repo
git clone [https://github.com/rgb-99/nlp-dataset-engine.git](https://github.com/rgb-99/nlp-dataset-engine.git)

# Install in editable mode
cd nlp-dataset-engine
pip install -e .[dev]

Usage

1. Ingest Data (CSV → JSONL)

Convert massive raw CSV files into clean, validated JSONL datasets for AI training. This runs in O(1) memory.

# Basic usage
nlp-engine ingest --input raw_data.csv --output clean_dataset.jsonl --col text

2. Automatic Observability & Filtering

The engine automatically enforces data quality:

• Language Detection: Removes non-English text by default.
• Health Report: Prints a statistical summary (drop rate, speed, count) after every run.
• Noise Filtering: Rejects rows where >30% of characters are symbols or numbers (e.g., "### 12345"). Disable English Filtering: If you want to keep all languages (e.g., for a multilingual dataset), use the --no-english flag:

nlp-engine ingest --input global_data.csv --output clean.jsonl --no-english

3. Recursive Folder Ingestion

Process an entire directory of data files (CSVs and TXTs) at once. The engine will find all compatible files in subfolders, process them, and aggregate the statistics.

# Ingest entire folder recursively
nlp-engine ingest --input ./data/raw_dump/ --output ./data/clean_combined.jsonl

4. Advanced Production Features (Big Data)

For massive datasets (Terabytes), use these flags to manage resources and failures.

Sharding: Automatically split output into smaller chunks (e.g., 10k rows per file).

nlp-engine ingest --input ./data --output clean.jsonl --shard-size 10000
# Output: clean-0000.jsonl, clean-0001.jsonl...

5. Data Integrity & Compression

Ensure your dataset is safe, verifiable, and compact.

Compression: Use --compress to save disk space (GZIP).

nlp-engine ingest --input ./data --output final.jsonl --compress
# Output: final-0000.jsonl.gz, final-0001.jsonl.gz...

6. Benchmarking

Measure the raw throughput (rows/second) of your environment. This runs the pipeline without writing to disk to test CPU/Validation speed.

nlp-engine benchmark --input large_dataset.csv
# Output:
#  BENCHMARK RESULTS
#  Rows/Sec: 12500.0
#  MB/Sec:   15.2 MB/s
# BENCHMARK RESULTS
# Rows/Sec: 12500.0
