Connecting the Dots with Context Graphs — Stephen Chin, Neo4j
Overview
This talk introduces context graphs as a solution to the problem of AI agents and systems lacking comprehensive understanding due to siloed data. It argues that by connecting disparate data sources, previous decision traces, and tool-use reasoning into a knowledge graph, AI can move from controlling engineers to being a controllable tool. This approach aims to provide grounded, complete information for more reliable AI-driven decision-making and application building.
Who should watch
- AI engineers and builders struggling with AI agents that lack context.
- Product Managers and engineers looking to build more robust and explainable AI-powered applications.
- Anyone interested in leveraging knowledge graphs and AI for better data integration and decision-making.
- Developers seeking to escape the limitations of fragmented data in enterprise systems.
Key takeaways
- Current AI tools often control engineers due to a lack of integrated context, leading to suboptimal decision-making.
- Context graphs, which connect various data sources and reasoning traces, offer a path to regaining control and enhancing AI capabilities.
- Knowledge graphs fundamentally store nodes (entities) and relationships, providing a structured way to aggregate and visualize information.
- Combining LLMs with knowledge graphs allows for richer data understanding, pattern identification, and insight generation.
- Graph RAG (Retrieval Augmented Generation) systems, powered by knowledge graphs, provide more complete and grounded information compared to standard LLMs or vector databases alone.
- Context graphs can store short-term, long-term, and reasoning memory, creating a persistent and accessible history for AI agents.
- Neo4j offers an open-source agent memory package that implements these concepts, enabling the creation of context graphs for various applications.
- Demonstrations showcased building context graphs for podcast analysis and a financial services application, highlighting explainability and auditable decision-making.
Notable quotes
*We are trapped as engineers. We are using AI coding tools or maybe they are using us.*
*Escape from the matrix, and have a system of reasoning where we actually have all these systems connected.*
*Context graphs are going to move forward the industry and dramatically change how we build applications.*
