Video transcripts are processed and represented as points in a high-dimensional space within the database. The position of each point reflects the semantic meaning ofd the transcript. When a student asks a question, the system sends the query to the vector database, which retrieves similar points (transcripts) based on semantic similarity. These similar transcripts are then sent to ChatGPT to generate a more informed and accurate answer.
