Quick Takeaways
- The generation brick in enterprise Document Intelligence is tightly controlled through a schema that binds model output to structured, verifiable data, reducing hallucinations and enabling precise extraction from passages.
- The schema acts as a flexible contract, adding fields like typed values, multi-span evidence, self-assessment, and feedback signals, allowing customizable and robust answer formats aligned with downstream needs.
- To ensure answer completeness and accuracy, the pipeline uses deterministic retrieval parameters, page overlaps, and post-generation checks, catching truncation and conflicts models can’t inherently detect.
- Enforcing schema adherence relies on constrained decoding (e.g., OpenAI’s structured output API), with fallback options like JSON validation, to reliably steer models toward verifiable, auditable enterprise answers.
Enhancing Accuracy with Typed Answers in RAG
Retrieval-Augmented Generation (RAG) systems aim to provide reliable, fact-based answers. Traditionally, models generate responses directly from passages, which can lead to hallucinations—when the AI invents information. To combat this, a new approach uses structured, typed answers as a contract between the pipeline and the model. This contract defines specific data types for responses—like amounts, dates, and tables—ensuring outputs are consistent and machine-readable. By grounding answers in retrieved passages, models produce less hallucinated, more trustworthy responses. This method streamlines downstream processes, such as exporting data into databases or visual dashboards. Implementing such contracts requires careful schema design, but it ultimately improves answer fidelity and user trust.
Structured Answers and Multi-Span Evidence
Many real-world questions demand answers more complex than a single piece of data. For example, a user seeking all exclusions related to flood damage needs multiple items, each supported by different evidence spans. To manage this, RAG systems incorporate multi-element answers, where each item carries its own evidence, often from non-contiguous text spans. This approach provides transparency, allowing users to verify the specific parts of a document backing each response. It also enables the model to handle listings, definitions, or exceptions effectively. The key benefit: answers become not only accurate but also explainable, fostering trust and enabling easier audits or compliance checks.
Controlling Hallucination and Improving Adoption
One of the biggest hurdles for enterprise adoption is model hallucination—confident but false responses. The typed answer contract addresses this by enforcing strict schemas and answer validation rules. By requiring the model to fill in predefined fields with precise, structured data, the system minimizes the risk of hallucination. Additionally, pipeline feedback fields, such as confidence scores and flags for conflicting evidence, guide subsequent steps—like requesting more retrieval if answers are partial or ambiguous. While this increases system complexity, it results in responses that are more reliable and auditable. As adoption grows, organizations recognize that controlling execution—instead of just prompting smarter—delivers more consistent, trustworthy AI solutions.
