The Problem with Relational Retrieval
Imagine you're building a chatbot that can have conversations with multiple agents. You want it to be able to understand the context of the conversation and retrieve relevant information. But does it actually work? The answer is no, not with traditional vector-based retrieval methods.
What is Vector RAG?
Vector RAG is a type of retrieval method that uses vectors to represent the relationships between different pieces of information. It's a powerful tool, but it has its limitations. When it comes to multi-agent conversations, vector RAG just isn't enough.
The Power of Context Graphs
That's where context graphs come in. A context graph is a layer that sits on top of the traditional retrieval method and provides a more nuanced understanding of the conversation context. It's like a map that shows how all the different pieces of information are related.
How it Works
Here's how it works:
- The context graph layer takes in the conversation history and breaks it down into individual pieces of information.
- It then analyzes the relationships between those pieces of information and creates a graph that represents the conversation context.
- The graph is used to retrieve relevant information and provide more accurate responses.
Benefits of Context Graphs
The benefits of context graphs are clear:
- More accurate retrieval: Context graphs provide a more nuanced understanding of the conversation context, which leads to more accurate retrieval of relevant information.
- Improved conversation flow: By understanding the relationships between different pieces of information, context graphs can help improve the flow of the conversation.
Benchmarking the Results
The results of the benchmarking test were surprising. Raw chat history performed poorly, with a low recall rate and a high error rate. Vector-only RAG performed better, but still had its limitations. The context graph layer, on the other hand, performed significantly better, with a high recall rate and a low error rate.
The Verdict
In the end, context graphs are the way to go for multi-agent conversations. They provide a more nuanced understanding of the conversation context and lead to more accurate retrieval of relevant information. If you're building a chatbot that needs to have conversations with multiple agents, you should definitely consider using a context graph layer.
