RAGToolkit.AI.VectorData.Abstractions

稀疏向量的契约与数据模型。不含任何 provider 实现。

核心类型

类型 说明
SparseEmbedding 稀疏向量：Indices（ReadOnlyMemory<int>）+ Values（ReadOnlyMemory<float>），继承 Embedding
ISparseEmbeddingGenerator<TInput> 稀疏嵌入生成器 —— 就是 IEmbeddingGenerator<TInput, SparseEmbedding>
VectorStoreSparseVectorAttribute 标在源文本属性上，告诉 provider"这个字段要产稀疏向量"
VectorStoreSparseVectorProperty 命令式版本：不想用特性标注时，直接构造它交给 provider

为什么需要它

Microsoft.Extensions.VectorData 目前没有稀疏向量的一等模型：

  • VectorStoreProperty 不可外部继承，provider 没法自己扩一个"稀疏向量属性"；
  • VectorStoreRecordDefinition 也不认识稀疏。

所以这里用平行的一套类型做桥接。等上游补上之后，这层可以退役。

示例

using RAGToolkit.AI.VectorData;

// 特性式：被标注的属性名就是稀疏向量的来源字段
public sealed class Doc
{
    [VectorStoreData]
    [VectorStoreSparseVector(StorageName = "sparse")]
    public string Content { get; set; } = "";
}

// 命令式
var sparseProperty = new VectorStoreSparseVectorProperty("Content")
{
    StorageName = "sparse",
};
