Sentiment-Analysis-Complex

🧠 Overview

Sentiment-Analysis-Complex is a large-scale synthetic sentiment analysis dataset designed for benchmarking modern NLP models under long-context, noisy, and semi-structured text conditions.

The dataset contains 10 million labeled samples with:

Long text sequences (20–40 tokens per sample)
Grammar-based sentence construction
Internet slang and hashtags
Rich vocabulary diversity
Balanced binary sentiment labels

It is optimized for:

Transformer benchmarking
Tokenizer stress testing
Long-context modeling
Robustness evaluation
Large-scale NLP pipelines

🧾 Data Format

Each line is a JSON object:

{
  "id": 123456,
  "text": "I really love how this system consistently delivers smooth reliable performance and scalable architecture with intuitive workflow and strong documentation lol #innovation",
  "label": "positive"
}

Fields

Field	Type	Description
`id`	Integer	Unique sample identifier
`text`	String	Input sentence (20–40 tokens)
`label`	String	Sentiment class (`positive`, `negative`)

Encoding: UTF-8 (emoji and special characters supported)

📊 Dataset Characteristics

✔️ Total samples: 10,000,000
✔️ Classes: positive / negative (balanced)
✔️ Sequence length: 20–40 tokens
✔️ Vocabulary size: ~300+ words
✔️ Includes slang and hashtags
✔️ Grammar-driven generation
✔️ Streaming-friendly JSONL format

🔬 Intended Use

This dataset is suitable for:

Sentiment classification benchmarking
Large-scale training pipelines
Tokenization analysis
Long-context modeling experiments
Data loading stress tests
Distributed training validation
Synthetic NLP research

⚠️ Limitations

Synthetic text — not reflective of natural human distribution.
Limited semantic depth and discourse structure.
No real-world bias modeling.
No multilingual coverage (English only).
No sarcasm or pragmatic reasoning.

Not recommended for production sentiment systems.
