Based on the knowledge about the Agentic Graph System (AGS) conceptual model created in the first part (Agentic Graph Systems: What They Are and How They Work), this blog aims to describe practical concerns and various applications of AGS. It also investigates the methods adopted to enhance the functionalities of AGS. It exhibits the versatility of knowledge graph orchestration, agent interactions, and integration layers in addressing dynamic environments and complex processes. Moreover, some of these applications include intelligent recommendation systems and complex query processing, which brings the point that even at high levels of complexity, AGS can offer highly accurate solutions along with unparalleled computational velocity, extensibility and flexibility in the most diverse fields.
Implementing Agentic Graph Systems
An Agentic Graph System (AGS) combines the power of knowledge graphs, autonomous agents, and advanced task orchestration to handle complex, dynamic workflows in real time. Implementing such a system requires careful integration of the Knowledge Graph Layer, Agent Layer, and Integration Layer, along with a solid understanding of modern AI and graph technologies. 
Designing the Knowledge Graph Layer
The Knowledge Graph Layer is a structured representation of entities (nodes) and relationships (edges). This layer is the foundation for storing and querying knowledge, facilitating decision-making, and enabling reasoning within the system.
Key Steps
-
Graph Database Selection: Start by choosing a suitable graph database:
-
Neo4j (Cypher query language) and Amazon Neptune (which supports RDF and Property Graph models) commonly store graph data.
-
JanusGraph offers scalable, open-source options that integrate with big data systems.
-
Data Modeling: Create a schema for your knowledge graph. Define nodes (e.g., user, product, event) and edges (e.g., "purchased," "recommended"). Use RDF for semantic graph models or property graphs for transactional data representation.
-
Data Ingestion: Import data into the graph using ETL tools like Apache Kafka (real-time streaming) or Apache Spark (large-scale data processing) to keep the graph updated continuously.
-
Querying: Utilize SPARQL or Cypher to interact with the graph. These languages allow you to query relationships and extract information to be used by the agents.
Building the Agent Layer
The Agent Layer is where autonomous agents live, interact with the knowledge graph, and perform tasks. Each agent operates autonomously, processes information from the graph, and makes decisions based on their role.
Key Steps
-
Agent Types: Define the roles of agents. Examples include:
-
Task Execution Agent: Responsible for executing specific tasks, such as processing data or interacting with the user.
-
Recommendation Agent: Uses the knowledge graph to suggest items based on user preferences and behaviour.
-
Conversational Agent: Handles user queries, interacts through natural language, and retrieves data from the knowledge graph.
-
Learning Integration: Implement Reinforcement Learning (RL) or Supervised Learning (SL) models to enable agents to adapt based on feedback. For example, agents may improve task execution efficiency or recommendation quality over time.
-
Natural Language Processing (NLP): If agents need to interact in human language, integrate models like BERT or GPT-3 to understand and generate natural language.
-
Agent Communication: Use standards such as FIPA ACL (Agent Communication Language) for inter-agent communication, allowing agents to collaborate or exchange information.
Developing the Integration Layer
The Integration Layer connects the knowledge graph, agents, and external systems. It is responsible for orchestrating tasks, ensuring real-time adaptation, and maintaining consistency in the flow of operations.
Key Steps
-
API and Microservices: Implement RESTful APIs or GraphQL for communication between agents and other system components. These APIs expose knowledge graph data, agent actions, and system interfaces.
-
Event-Driven Architecture: Employ event-driven architecture to enable real-time responsiveness. Tools like Apache Kafka or AWS Lambda can handle event triggers and route them to the appropriate agents for action.
-
Task Orchestration: Use Apache Airflow or Argo Workflows to manage task execution and dependencies. These tools ensure tasks are executed in the correct order, respecting dependencies defined by the knowledge graph.
-
Path Processing: Enable path processing in the knowledge graph to allow agents to identify and utilize relevant paths for decision-making. This involves querying the graph to extract and integrate information into agent memory.
Incorporating COT, TOT, and GOT Models
Analysis models such as COT, TOT, and GOT can improve agents' reasoning and decision-making abilities in an Agentic Graph System. These models support how agents delve into complex queries and parse them into a work plan with a marked progression of action.
-
COT (Chain of Thought): This model allows agents to reduce a problem to their parts and systematically reason from one part to another.
-
AGS in COT allows the knowledge graph to be queried multiple times, and each subsequent query should use the previous result as input.
-
TOT (Thoughts of Thoughts): Based on COT, the TOT model allows agents to assess suitable reasoning paths and select the proper one. This is especially important in environments where a particular task might change or have been altered midstream.
-
GOT (Graph of Thoughts): The reasoning process is represented by a graph structure for the GOT model, which permits the system to monitor various reasoning steps and connections.

It becomes almost impossible to identify fraudulent transactions because they operate in a sequence, and fraudsters access many data sources.
Challenge
-
Fraud identification in financial transactions is a global issue that organizations in the financial industry face constantly.
-
More often, fraud schemes have multiple integrated characteristics, making it incredibly challenging for analysts to notice them utilizing pure low-level syntactical rules.
How AGS Can Solve It
In AGS, the nodes of a knowledge graph are accounts, transactions, users, and institutions. By exploring complex graph manipulation, agents can discover positive and negative patterns and connections between these entities. There is also an ongoing evaluation of transactions through the so-called agentic workflow, with the help of which, using the knowledge graph, fraud is identified, for example, by changes in the behaviour of transactions or their connection. After identifying the possibility of fraud, the system can immediately look up associated activities, inform investigators, and present procedures to minimize the risk.
Value Provided
Real-Time Fraud Detection
Real-time work with AGS enables the faster identification of suspicious activities and initiates intervention.
