Natural-language processing helps systems work with text and speech, including classification, extraction, search and generation. The appropriate method depends on the task and the evidence needed to assess the result.
Define the language, document types and expected output. For extraction, specify which fields must be present and how uncertain or missing values should be represented. A system should not invent an invoice number or obligation because the requested output format expects one.
Test representative documents, including spelling variation, mixed languages and unusual layouts. Compare extracted information with the original source and distinguish retrieval relevance from factual correctness. Evaluate the languages actually used by customers instead of assuming English results apply to all editions.
Preserve source references and route ambiguous cases for review. Monitor errors as document formats change. Select the simplest method that meets the requirement, keeping generation separate from fields that need exact reproduction.
