Refinery components for the Sayou Data Platform

sayou-refinery

The Universal Data Cleaning & Normalization Engine for Sayou Fabric.

sayou-refinery acts as the "Cleaning Plant" in your data pipeline.

It transforms heterogeneous raw data (JSON Documents, HTML, DB Records) into a standardized stream of SayouBlocks, ensuring that downstream components (like Chunkers or LLMs) receive clean, uniform data regardless of the original source format.

💡 Core Philosophy

"Flatten Structure, Polish Content."

Refinery operates in two distinct stages to guarantee data quality:

1. Normalization (Shape Shifting): Converts complex structures (nested JSON, HTML trees, DB Rows) into a linear list of SayouBlocks.
2. Processing (Cleaning): Applies a chain of cleaning agents (Regex, Masking, Deduplication) to improve data hygiene.

📦 Installation

pip install sayou-refinery

⚡ Quick Start

The RefineryPipeline orchestrates the normalization and processing chain.

from sayou.refinery.pipeline import RefineryPipeline

def run_demo():
    # 1. Initialize with specific cleaning rules
    pipeline = RefineryPipeline()
    pipeline.initialize(
        mask_email=True,
        outlier_rules={"price": {"min": 0, "max": 1000, "action": "clamp"}}
    )

    # 2. Raw Data (e.g., from sayou-document)
    raw_doc = {
        "metadata": {"title": "Test Doc"},
        "pages": [{
            "elements": [
                {"type": "text", "text": "Contact: [e-mail]"},
                {"type": "text", "text": "   Dirty   Whitespace   "}
            ]
        }]
    }

    # 3. Run Pipeline
    # strategy: 'standard_doc', 'html', 'json', etc.
    blocks = pipeline.run(raw_doc, strategy="standard_doc")

    # 4. Result
    for block in blocks:
        print(f"[{block.type}] {block.content}")
        
        # Output:
        # [md_meta] --- title: Test Doc ...
        # [md] Contact: [EMAIL]
        # [md] Dirty Whitespace

if __name__ == "__main__":
    run_demo()

🔑 Key Components

Normalizers

• DocMarkdownNormalizer: Converts Sayou Document Dicts into Markdown blocks.
• HtmlTextNormalizer: Strips HTML tags and scripts, extracting clean text.
• RecordNormalizer: Converts DB rows or JSON objects into 'record' blocks.

Processors

• TextCleaner: Normalizes whitespace and removes noise via regex.
• PiiMasker: Masks sensitive info like emails and phone numbers.
• Deduplicator: Removes duplicate content blocks.
• Imputer: Fills missing values in record blocks.
• OutlierHandler: Filters or clamps numerical outliers in records.

🤝 Contributing

We welcome contributions for new Normalizers (e.g., CsvNormalizer, LogNormalizer) or Processors (e.g., LangChainFilter).
