The brief

Designed around the real friction.

High-quality parsing can become expensive when every document is sent through the most capable model. The research problem is to lower the average cost without degrading the fields recruiters actually depend on.

The working direction is a hybrid router: deterministic rules for obvious structure, smaller task-specific models for common patterns and human review for low-confidence fields. Evaluation is field-level so cost and quality can be tuned together rather than argued about in the abstract.

How it works

A system with a clear next move.

01

Classify document complexity before choosing an extraction path.

02

Use lightweight rules and models for the majority of predictable fields.

03

Escalate only the ambiguous cases, then measure quality against cost.

Project notes

What we are building toward

A measurable path toward lower parsing cost, stronger traceability and a more responsible use of AI in a workflow that affects real candidates.

Overview

PDF, Word, and HTML documents parsed into consistent structured records using a combination of rule-based and model-driven approaches.

Product focus

High throughput, low cost per document, and a confidence layer that flags uncertain extractions for human review.
