Revolutionizing Semantic Search with RAG and Knowledge Graphs

As the scale of data increases in both size and complexity, the need for retrieving relevant information from enormous data repositories is more pressing than ever.? Semantic search is a sophisticated approach that goes beyond keyword matching and dives into the deeper context behind a query.? Semantic search is critical nowadays to return the essence of the search rather than only exact matches.?

However, despite the advanced capabilities of semantic search, it faces significant challenges. Traditional algorithms struggle with understanding the nuances of the human language, leading to a superficial level understanding of the user's intent. In addition, the exponential increase in volume and variety of data makes the extraction of relevant information even more challenging.?

This is where Retrieval-Augmented Generation (RAG) comes into play. RAG is a cutting-edge approach that combines the power of Large Language Models (LLMs) such as ChatGPT with sophisticated information retrieval techniques. We can now integrate the power of LLMs with our database query requests for more power retrieval than ever before possible.?

RAG operates in the two main phases of retrieval and generation. Initially, RAG retrieves relevant information from a database by understanding the context and nuance of the query. This is done using what are called embeddings. Embeddings are a computer representation of the semantic meaning of the text and are stored as large vectors. The LLMs are used to convert the text into the vector embeddings and can be used for retrieval in the RAG process. Once the text is embedded using the LLM, the prompt or query the user writes is also embedded then compared to the list of all embeddings in the database to return the closest matching scores.?

Introducing Knowledge Graphs and Vector Storage?

Knowledge graphs represent a transformative way to store, organize, and process data. These are essentially vast, interconnected networks of entities and their relationships structured in a way that mirrors human understanding. Entities can represent people, places, transactions, etc. The relationships between them enable a nuanced representation of real-world knowledge.?

Regarding semantic search, knowledge graphs play a key role. They enable understanding between different entities and go beyond mere keyword matching to reveal hidden connections and patterns that yield more accurate and contextually aware insights.?

?

We can now integrate knowledge graphs with RAG systems to provide a powerful enhancement to semantic search. This integration allows RAG to access structured and semantically rich network information as well as the embeddings from the LLM to provide not just the requested content but also the context of relationships stored in the database. This leads to more precise and accurate retrieval of information in a flexible storage design possessing the power of LLMs and the flexibility and explainability of knowledge graphs.?

By leveraging a knowledge graph such as Neo4j for vector storage, you set your organization up for success in the field of semantic search by providing a vibrant collection of data, as well as a highly scalable and efficient retrieval solution. As today’s data-driven world increases in volume, velocity, and variety of data, it is all the more important to create an appropriate data architecture to enable not only scalable storage but also knowledgeable retrieval utilizing the recent advancements in the domain of artificial intelligence and, specifically, the powerful additions of text embeddings provided by state-of-the-art LLMs.?
