This article discusses the challenges and techniques for extracting structured data from subrogation demand letters, which are unstructured documents. The author highlights that these letters have a two-party structure where identifiers like names, policy numbers, and claim numbers must be correctly assigned to either the demanding or responding party. A key challenge is distinguishing between a carrier's claim number, a policy number, and a vendor's file number, as they often appear similar. The proposed solution involves using possessive phrasing within the letter (e.g., 'our insured,' 'your policyholder') as a signal for correct assignment, making the extraction process reviewable by humans. Additionally, the article addresses the extraction of demand amounts, which are often itemized and require cross-field validation to ensure accuracy and identify potential errors like incorrect subtractions or comparative negligence allocations.
