In this episode we talk to Kirk Marple about the power of Knowledge Graphs when combined with GenAI models.  Kirk explained the growing relevance of knowledge graphs in the AI era, the practical applications, their integration with LLMs, and the future potential of Graph RAG.

Kirk Marple a veteran of Microsoft and General Motors, Kirk has spent the last 30 years in software development and data leadership roles. He also successfully exited the first startup he founded, RadiantGrid, acquired by Wohler Technologies.

Now, as the technical founder and CEO of Graphlit, Kirk and his team are streamlining the development of vertical AI apps with their end-to-end, cloud based offering that ingests unstructured data and leverages retrieval augmented generation to improve accuracy, domain specificity, adaptability, and context understanding – all while expediting development.

Episode Summary -

• Introduction to Knowledge Graphs:
• Knowledge graphs extract relationships between entities like people, places, and things, facilitating efficient information retrieval.
• They represent intricate interactions and interrelationships, enabling users to "walk the graph" and uncover deeper insights.
• 
  
• Importance in the AI Era:
• Knowledge graphs enhance data retrieval and filtering, crucial for feeding accurate data into large language models (LLMs) and multimodal models.
• They provide an additional axis for information retrieval, complementing vector search.
• Industry Use Cases:
• Commonly used in customer data platforms and CRM models to map relationships within and between companies.
• Knowledge graphs can convert complex datasets into structured, easily queryable formats.
• Challenges and Limitations:
• Familiarity with graph databases and the ETL process for graph data integration is still developing.
• Graph structures are less common and more complex than traditional relational models.
• Integrating Knowledge Graphs with LLMs:
• Knowledge graphs enrich data integration and semantic understanding, adding context to text retrieved by LLMs.
• They can help reduce hallucinations in LLMs by grounding responses with more accurate and comprehensive context.
• Graph RAG (Retrieval Augmented Generation):
• Combines knowledge graphs with RAG to provide additional context for LLM-generated responses.
• Allows retrieval of data not directly cited in the text, enhancing the breadth of information available for queries.
• Scalability and Efficiency:
• Effective graph database architectures can handle large-scale graph data efficiently.
• Graph RAG requires a robust ingestion pipeline and careful management of data freshness and retrieval processes.
• Future Developments:
• Growing interest and implementation of knowledge graphs and Graph RAG in various industries.
• Potential for new tools and standardization efforts to make these technologies more accessible and effective.
• Graphlit: Simplifying Knowledge Graphs:
• The platform focuses on simplifying the creation and use of knowledge graphs for developers.
• Provides APIs for easy integration, supporting domain-specific vertical AI applications.
• Offers a unified pipeline for data ingestion, extraction, and knowledge graph construction.
• Open Source and Community Contributions:
• Recommendations for libraries and projects in the knowledge graph space.
• Notable contributors and projects include data extraction libraries and AI agent initiatives.
