MarkZither.Rag.Chunking

NuGet License: MIT

Token-aware sliding-window chunking primitives for retrieval-augmented generation (RAG) pipelines in .NET.

Splits long documents into overlapping token-bounded chunks ready for embedding, with optional HTML stripping. No HtmlAgilityPack dependency.

Installation

dotnet add package MarkZither.Rag.Chunking --version 0.0.1-alpha.1

Quick Start

// Register via DI
services.AddChunking();

// Or resolve manually
ITokenEncoder encoder = new TiktokenEncoder();
IChunkingService chunker = new SlideWindowChunkingService(encoder);

var options = new ChunkOptions
{
    ChunkSize = 512,        // tokens per chunk
    ChunkOverlap = 128,     // overlap tokens between chunks
    MaxChunksPerDocument = 200,
    StripHtml = true        // strip HTML before chunking
};

IReadOnlyList<TextChunk> chunks = await chunker.ChunkAsync(text, options, ct);

foreach (var chunk in chunks)
{
    Console.WriteLine($"[{chunk.ChunkIndex + 1}/{chunk.TotalChunks}] {chunk.TokenCount} tokens: {chunk.Text[..Math.Min(80, chunk.Text.Length)]}...");
}

API

IChunkingService

Task<IReadOnlyList<TextChunk>> ChunkAsync(string text, ChunkOptions options, CancellationToken cancellationToken = default);

ChunkOptions

Property Default Description
ChunkSize 512 Maximum tokens per chunk
ChunkOverlap 128 Token overlap between consecutive chunks
MaxChunksPerDocument 200 Hard cap on chunks produced per document
StripHtml true Strip HTML tags before chunking

TextChunk

record TextChunk(string Text, int ChunkIndex, int TotalChunks, int TokenCount);

ITokenEncoder

Abstraction over the tokenizer. Default implementation is TiktokenEncoder using cl100k_base encoding (compatible with nomic-embed-text, text-embedding-ada-002, and similar models).

DI Registration

// Registers TiktokenEncoder as ITokenEncoder and SlideWindowChunkingService as IChunkingService
services.AddChunking();
