SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Splits long text into semantic chunks organized by headings and double newlines, with a robust fallback to ~800-character chunks with a 50-character overlap, returning labeled pieces ready for use with language models.

Core Features & Use Cases

  • Semantic chunking by headings and structure for precise context slices.
  • Fallback chunking when structure is missing, with configurable chunk sizes and overlap.
  • Output chunks with id, index, label, and text for seamless retrieval and reassembly in downstream pipelines.

Quick Start

Chunk the input document to generate labeled chunks suitable for feeding into a language model.

FAQPage Schema
How do I split long documents into chunks for language models?

To split long documents into chunks for language models, you can use semantic chunking, which organizes text by headings and double newlines. It returns labeled pieces ready for retrieval and prompt engineering.

What is semantic chunking and when do I need it for text processing?

Semantic chunking is a text processing technique that splits long text into meaningful chunks organized by document structure. You need it when preparing large documents or knowledge bases for retrieval and language model workflows.

How do I prepare large documents for retrieval and prompt engineering?

You prepare large documents for retrieval and prompt engineering by chunking text into semantic slices. This generates labeled chunks that maximize model context and can be seamlessly reassembled in downstream AI pipelines.

What happens when text has no headings for structural chunking?

When text lacks headings for structural chunking, the process applies a robust fallback. It splits the document into approximately 800-character chunks with a 50-character overlap to ensure continuous context across the text.

Can I get labeled output from text chunking for downstream pipelines?

Yes, text chunking can return an array of labeled output for downstream pipelines. Each chunk includes an id, index, label, and text, ensuring seamless retrieval and reassembly in AI workflows.

Does semantic chunking work for knowledge bases without document structure?

Semantic chunking works for knowledge bases without document structure by using a fallback mechanism. It generates configurable chunks with overlap to maintain context, making unstructured text ready for language models.
