Watch On-Demand: Semantic Layer + LLM = AI Chatbot for Fast Answers

Learn how to feed an LLM and launch an AI chatbot lightning-fast with a Semantic Layer

  • Quantatec
  • Patterson Consulting

In this webinar, speakers from Cube, Quantatec, and Patterson Consulting, explored the potential of combining a semantic layer with a Language Learning Model (LLM) to create an AI chatbot for quick, accurate responses. Here are five key takeaways from the webinar:

1. Enhancing Accessibility with a Semantic Layer

Brian Bickell of Cube opened the session by introducing the concept of a universal semantic layer. It aims to make cloud data more accessible and consistent. A semantic layer also addresses the challenges of managing multiple data sources and consumers by providing features like data modeling, access control, caching functionality, and various APIs for downstream connectivity. The result is better data consistency, improved security, and increased developer productivity.

2. Enable Seamless Integration

Semantic layers can be crucial in modern data stacks. Situated adjacent to data sources, they enable seamless integration with downstream tools. Furthermore, the semantic layer can enhance an AI chatbot's performance, especially when it interfaces with natural language queries, by providing the LLM with well-defined API specifications and querying options.

3. Tailored Solutions with AI Chatbots

Quantatec's Mauricio Cirelli provided insights on how they leveraged Cube's semantic layer to deploy an AI chatbot. The chatbot enhances user experience by answering user queries directly, without the need for programming or dashboard creation. This solution was a response to the challenge of generating user-specific reports––a process that was previously labor-intensive and time-consuming.

4. Leveraging Retrieval Augmented Generation

Josh Patterson of Patterson Consulting expounded on the concept of retrieval augmented generation. By retrieving relevant information from a knowledge repository and using it to augment the prompt for a large language model like GPT-3, you can get more precise results. A semantic layer enhances this process by providing a unified API, better user management, and the capability to add quality metadata on top of data models.

5. Security Measures For The Application

The panel of experts also touched on the circumspect security measures in chatbot applications. Three layers of protection work in step to safeguard data: prevention of execution of deleted statements, a semantic layer that restricts access to data retrieval, and finally, the inherent database protection. To further ensure data security, Cube's query rewrite functionality allows user-specific data access, providing necessary security in a multi-tenancy system like Quantatech.

In conclusion, combining a semantic layer and LLM in AI chatbot implementation offers a streamlined, secure, and efficient solution to data queries and report generation.
