NCA-GENL Question 25
Select 3You are tasked with building a Retrieval-Augmented Generation (RAG) system for a customer support chatbot. The chatbot must retrieve accurate and relevant answers from a curated knowledge base of product manuals, FAQs, and troubleshooting guides. Which steps should you take to curate and embed the content dataset for optimal performance?
- A
Ensure the dataset is cleaned by removing duplicate entries and irrelevant content.
- B
Convert all retrieved documents into embeddings using a pre-trained language model.
- C
Use a domain-specific fine-tuned embedding model for converting text to embeddings.
- D
Embed the content dataset first, then clean it by removing low-quality or irrelevant entries.
- E
Organize the dataset into a structured format, such as question-answer pairs, for better retrieval performance.

Correct answers: A, C, E
Explanation
For a RAG system to deliver accurate and contextually relevant answers, the dataset must be cleaned for quality, embedded using domain-specific models for better semantic understanding, and structured in a way that aligns with the query and retrieval process. These steps ensure that the system retrieves the most appropriate information from the knowledge base, improving the overall user experience.
- A. Correct.
Cleaning the dataset ensures that duplicate and irrelevant content do not negatively impact the retrieval process, which is critical for generating accurate answers in a RAG system.
- B. Incorrect.
While converting documents into embeddings is necessary, using a pre-trained language model without domain-specific fine-tuning may result in less accurate retrievals, especially for specialized domains like customer support.
- C. Correct.
Domain-specific fine-tuned embedding models provide better semantic understanding of the text, leading to more relevant and accurate retrievals.
- D. Incorrect.
Embedding the content dataset before cleaning can lead to the inclusion of irrelevant or low-quality data in the embeddings, reducing the system's accuracy and efficiency.
- E. Correct.
Organizing the dataset into structured formats, such as question-answer pairs, enhances the retrieval process by aligning the data structure with the typical query format.
