Вставка
- Опубліковано 31 бер 2024
- This discussion explores the use of knowledge graphs (KGs) in RAG systems, focusing on their potential to improve retrieval and context compilation for large language models (LLMs).
* The discussion includes technical details about specific tools and techniques, such as Azure AI Search, Rebel, and XML data structures.
* The participants share practical experiences and challenges encountered in their work with RAG and KGs.
* The conversation highlights the evolving nature of the field and the need for further research and development.
*Key Participants:*
* Kirk Marple: Graflet CEO, discussing their LLM platform with integrated KG capabilities.
* Sujit Pal: Elsevier data scientist, sharing his experience with GraphRAG and knowledge graph construction.
* Darin Plutchok: taxonomist and Product Manager, AI Innovation, offering insights on the value of hierarchical structures and knowledge representation.
* Eric Landry: Data scientist, raising questions about the evaluation and complexity of KG-based RAG approaches.
*Main Topics:*
1. *Graflet Platform:*
* Provides a managed service for unstructured data pipelines and RAG with multi-modal capabilities.
* Leverages KGs for semantic search and context enrichment.
* Offers a developer-friendly API and free tier for experimentation.
2. *GraphRAG and Knowledge Graph Construction:*
* Sujit Pal discusses his experiments with GraphRAG, extracting entities and linking them based on co-occurrence.
* Explores the use of triples (subject-predicate-object) to represent relationships within the KG.
* Highlights the potential of KGs to improve recall and handle broad queries that span multiple chunks.
3. *Challenges and Evaluation:*
* Eric Landry raises concerns about the added complexity of KG-based RAG and the need for thorough evaluation.
* The group discusses the difficulty of evaluating RAG systems, particularly the lack of reliable ground truth data.
* Kirk Marple shares Graflet's ongoing evaluation efforts to compare KG-enhanced RAG with standard RAG approaches.
4. *Information Retrieval and Compilation:*
* The discussion emphasizes the importance of effective information retrieval (IR) for RAG, highlighting its shift towards "information retrieval compilation."
* Kirk Marple describes Graflet's use of semantic search and prompt rewriting to improve retrieval accuracy.
* Darin Plutchok emphasizes the need to consider data quality and appropriate data manipulation for optimal LLM context.
5. *Skills and Resources for RAG Development:*
* Sam Charrington inquires about the skillset required for successful RAG development, noting the importance of search expertise.
* The group discusses the value of combining IR, information extraction (IE), and ontology knowledge for effective RAG implementation.
* The need for educational resources and a clear learning path for aspiring RAG practitioners is highlighted. - Наука та технологія
