Streamline RAG applications with intelligent metadata filtering using Amazon Bedrock

Flipboard

One effective way to improve context relevance is through metadata filtering, which allows you to refine search results by pre-filtering the vector store based on custom metadata attributes. By combining the capabilities of LLM function calling and Pydantic data models, you can dynamically extract metadata from user queries.

Metadata filtering for tabular data with Knowledge Bases for Amazon Bedrock

AWS Machine Learning Blog

However, information about one dataset can be in another dataset, called metadata. Without using metadata, your retrieval process can cause the retrieval of unrelated results, thereby decreasing FM accuracy and increasing cost in the FM prompt token. This change allows you to use metadata fields during the retrieval process.

Knowledge Bases for Amazon Bedrock now supports metadata filtering to improve retrieval accuracy

AWS Machine Learning Blog

To refine the search results, you can filter based on document metadata to improve retrieval accuracy, which in turn leads to more relevant FM generations aligned with your interests. With this feature, you can now supply a custom metadata file (each up to 10 KB) for each document in the knowledge base. Virginia) and US West (Oregon).

How to establish lineage transparency for your machine learning initiatives

IBM Journey to AI blog

But trust isn’t important only for executives; before executive trust can be established, data scientists and citizen data scientists who create and work with ML models must have faith in the data they’re using. This can lead to more accurate predictions and better decision-making.

Access control for vector stores using metadata filtering with Knowledge Bases for Amazon Bedrock

AWS Machine Learning Blog

With metadata filtering now available in Knowledge Bases for Amazon Bedrock, you can define and use metadata fields to filter the source data used for retrieving relevant context during RAG. This helps improve the relevance and quality of retrieved context while reducing potential hallucinations or noise from irrelevant data.
