This article discusses how graphs can be used to model different types of agent memory. The authors, inspired by Harrison Chase's talk at the DeepLearning.AI Dev Day conference, explore various aspects of memory management in agentic systems and provide a framework for implementing these concepts in a graph database such as Neo4j. They identify four main types of memory: short-term, long-term, procedural, and temporal, each with its own characteristics and challenges. The authors propose data models for each type of memory, including semantic memory, which stores facts about the world, episodic memory, which stores remembered experiences, procedural memory, which stores how to do something, and temporal memory, which stores how data changes over time. They also discuss the importance of managing memory in agentic systems and provide examples of how these concepts can be implemented in practice. The article aims to provide a solid foundation for solving the problem of agent memory management and offers a starting point for further exploration and development.
