Extract questions from the usual or reference kind – The primary API name is made to extract an inventory of questions and sub-questions from the usual or reference kind. This listing serves as a baseline or reference level for comparability with different kinds. By extracting the questions from the reference kind, we will set up a benchmark towards which different kinds may be evaluated.
Extract questions from the customized kind – The second API name is made to extract an inventory of questions and sub-questions from the customized kind or the shape that must be in contrast towards the usual or reference kind. This step is critical as a result of we have to analyze the customized kind’s content material and construction to establish its questions and sub-questions earlier than we will examine them with the reference kind.
By having the questions extracted and structured individually for each the reference and customized kinds, the answer can then cross these two lists to the Amazon Bedrock API for the ultimate comparability step. This strategy maintains the next:
Correct comparability – The API has entry to the structured knowledge from each kinds, making it simple to establish matches, mismatches, and supply related reasoning
Environment friendly processing – Separating the extraction course of for the reference and customized kinds helps keep away from redundant operations and optimizes the general workflow
Observability and interoperability – Conserving the questions separate permits higher visibility, evaluation, and integration of the questions from completely different kinds
Hallucination avoidance – By following a structured strategy and counting on the extracted knowledge, the answer helps keep away from producing or hallucinating content material, offering integrity within the comparability course of
This two-step strategy makes use of the capabilities of the Amazon Bedrock API whereas optimizing the workflow, enabling correct and environment friendly kind comparability, and selling observability and interoperability of the questions concerned.
