Outliers Detection in Python

A certificate of analysis (CoA) is one of the most information-dense documents in regulated industries. It carries test results, method references, accreditation details, chain-of-custody information, and the laboratory’s sign-off — all in a format designed for human reading, not machine parsing.

Contracts are the hardest document type to extract data from reliably. Invoices have a predictable structure. Lab reports have defined fields. Contracts are natural language documents, and the information you need — key dates, party names, payment terms, renewal clauses, termination conditions — can appear anywhere, phrased in many different ways, across documents that range from two pages to two hundred.

Customs declarations are among the most error-sensitive documents in logistics. A wrong tariff code or an incorrectly extracted commodity value can trigger delays, fines, or hold actions. At the same time, import/export operations process hundreds or thousands of declarations per month, and the manual effort of verifying and entering data from these documents is substantial.
