The response generated with the ground prompt is exactly how the enterprise would want the customer to be notified. The enriched customer data embedding into an email response from Gen AI is an automation that would be remarkable to scale up and sustain enterprises.

Enterprise LLM Grounding Solutions for Software Systems

There are multiple ways to ground the data in enterprise systems, and a combination of these techniques could be used for effective data grounding and prompt generation specific to the use case.  The two primary contenders as potential solutions for implementing retrieval augmented generation(grounding) are

  1. Application Data|Knowledge graphs
  2. Vector embeddings and semantic search

Usage of these solutions would depend on the use case and the grounding you want to apply. For example, vector stores provided responses can be inaccurate and vague, whereas knowledge graphs would return precise, accurate, and stored in a human-readable format.

A few other strategies that could be blended on top of the above could be

  • Linking to External APIs, Search engines
  • Data Masking and compliance adherence systems
  • Integrating with internal data stores, systems
  • Realtime Unifying data from multiple sources

In this blog, let’s look at a sample software design on how you can achieve with enterprise application data graphs.

Enterprise Knowledge Graphs

A knowledge graph can represent semantic information of various entities and relationships among them. In the Enterprise world, they store knowledge about customers, products, and beyond. Enterprise customer graphs would be a powerful tool to ground data effectively and generate enriched prompts. Knowledge graphs enable graph-based search, allowing users to explore information through linked concepts and entities, which can lead to more precise and diverse search results.

Comparison with Vector Databases

Choosing the grounding solution would be use-case-specific. However, there are multiple advantages with graphs over vectors like

Criteria Graph grounding Vector grounding
Analytical Queries Data graphs are suitable for structured data and analytical queries, providing accurate results due to their abstract graph layout. Vector data stores may not perform as well with analytical queries as they mostly operate on unstructured data, semantic search with vector embeddings, and rely on similarity scoring.
Accuracy and Credibility knowledge graphs use nodes and relationships to store data, returning only the information present. They avoid incomplete or irrelevant results. Vector databases may provide incomplete or irrelevant results, mainly due to their reliance on similarity scoring and predefined result limits.
Correcting Hallucinations Knowledge graphs are transparent with a human-readable representation of data. They help identify and correct misinformation,  trace back the pathway of the query, and make corrections to it, improving LLM (Large Language Model) accuracy. Vector databases are often seen as black boxes not stored in readable format and may not facilitate easy identification and correction of misinformation.
Security and Governance Knowledge graphs offer better control over data generation, governance, and compliance adherence, including regulations like GDPR. Vector databases may face challenges in imposing restrictions and governance due to their nontransparent nature.

High-Level Design

Let us see on a very high level how the system can look for an enterprise that uses knowledge graphs and open LLMs for grounding.

The base layer is where enterprise customer data and metadata are stored across various databases, data warehouses, and data lakes. There can be a service building the data knowledge graphs out of this data and storing it in a graph db. There can be numerous enterprise services|micros services in a distributed cloud native world that would interact with these data stores. Above these services could be various applications that would leverage the underlying infra.

Applications can have numerous use cases to embed AI into their scenarios or intelligent automated customer flows, which requires interacting with internal and external AI systems. In the case of generative AI scenarios, let’s take a simple example of a workflow where an enterprise wants to target customers via an email offering a few discounts on personalized recommended products during a holiday season. They can achieve this with first-class automation, leveraging AI more effectively.

High-level design

The Workflow

  • Workflow that wants to send an email can take the help of open Gen-AI systems by sending a grounded prompt with customer contextualized data.
  • The workflow application would send a request to its backend service to obtain the email text leveraging GenAI systems.
  • Backend service would route the service to a prompt generator service, which routes to a grounding engine.
  • The grounding engine grabs all the customer metadata from one of its services and retrieves the customer data knowledge graph.
  • The grounding engine traverses the graph across the nodes and relevant relationships extracts the ultimate information required, and sends it back to the prompt generator.
  • The prompt generator adds the grounded data with a pre-existing template for the use case and sends the grounded prompt to the open AI systems the enterprise chooses to integrate with(e.g., OpenAI/Cohere).
  • Open GenAI systems return a much more relevant and contextualized response to the enterprise, sent to the customer via email.

Let’s break this into two parts and understand in detail:

1. Generating Customer Knowledge graphs

The below design suits the above example, modeling can be done in various ways according to the requirement.

Data Modeling: Assume we have various tables modeled as nodes in a graph and join between tables as relationships between nodes. For the above example, we need

  • a table that holds the Customer’s data,
  • a table that holds the product data,
  • a table that holds the CustomerInterests(Clicks) data for personalized recommendations
  • a table that holds the ProductDiscounts data

It’s the enterprise’s responsibility to have all of this data ingested from multiple data sources and updated regularly to reach customers effectively.

Let’s see how these tables can be modeled and how they can be transformed into a customer graph.

2. Graph Modeling

From the above graph visualizer, we can see how customer nodes are related to various products based on their clicks engagement data and further to the discounts nodes. It’s easy for the grounding service to query these customer graphs, traverse these nodes through relationships, and obtain the required information around discounts eligible to respective customers.

A sample graph node and relationship JAVA POJOs for the above could look similar to the below

public class KnowledgeGraphNode implements Serializable {
 private final GraphNodeType graphNodeType;
 private final GraphNode nodeMetadata;
}


public interface GraphNode {
}


public class CustomerGraphNode implements GraphNode {
 private final String name;
 private final String customerId;
 private final String phone;
 private final String emailId;
}
public class ClicksGraphNode implements GraphNode {
 private final String customerId;
 private final int clicksCount;
}


public class ProductGraphNode implements GraphNode {
 private final String productId;
 private final String name;
 private final String category;
 private final String description;
 private final int price;
}


public class ProductDiscountNode implements GraphNode {
 private final String discountCouponId;
 private final int clicksCount;
 private final String category;
 private final int discountPercent;
 private final DateTime startDate;
 private final DateTime endDate;
}
public class KnowledgeGraphRelationship implements Serializable {

 private final RelationshipCardinality Cardinality;

}

public enum RelationshipCardinality {

 ONE_TO_ONE,

 ONE_TO_MANY

}

A sample raw graph in this scenario could look like below

Traversing through the graph from customer node ‘Taylor Williams’ would solve the problem for us and fetch the right product recommendations and eligible discounts.

There are numerous graph stores available in the market that can suit enterprise architectures. Neo4j, TigerGraph, Amazon Neptune, and OrientDB are widely adopted as graph databases.

We introduce the new paradigm of Graph Data Lakes, which enables graph queries on tabular data (structured data in lakes, warehouses, and lakehouses). This is achieved with new solutions listed below, without the need to hydrate or persist data in graph data stores, leveraging Zero-ETL.

  • PuppyGraph(Graph Data Lake)
  • Timbr.ai

Compliance and Ethical Considerations

Data Protection: Enterprises must be responsible for storing and using customer data adhering to GDPR and other PII compliance. Data stored needs to be governed and cleansed before processing and reusing for insights or applying AI.

Hallucinations & Reconciliation: Enterprises can also add reconciling services that would identify misinformation in data, trace back the pathway of the query, and make corrections to it, which can help improve LLM accuracy.  With knowledge graphs, since the data stored is transparent and human-readable, this should be relatively easy to achieve.

Restrictive Retention policies: To adhere to data protection and prevent misuse of customer data while interacting with open LLM systems, it is very important to have zero retention policies so the external systems enterprises interact with would not hold the requested prompt data for any further analytical, or business purposes.

Conclusion

In conclusion, Large Language Models (LLMs) represent a remarkable advancement in artificial intelligence and natural language processing. They can transform various industries and applications, from natural language understanding and generation to assisting with complex tasks. However, the success and responsible use of LLMs require a strong foundation and grounding in various key areas.
