概要

What is Portuguese Legal Document PDF Metadata Extractor?

A robust tool for extracting structured metadata from Portuguese legal document PDFs, specifically designed for European Case Law Identifier (ECLI) formatted documents. It provides high accuracy extraction with two extractor variants, confidence scoring, and field classification—suitable for legal document processing and validation.

How to use Portuguese Legal Document PDF Metadata Extractor?

Install with Python 3.8+ and pip install pdfplumber. Use via the CLI: python production_extractor.py "pdfs/document.pdf" -o "results/" for single files, or python production_extractor.py "pdfs/" -g "ground_truth/ground_truth.json" -o "results/" for batch processing with ground truth validation. The PortugueseLegalPDFExtractor class also offers a programmatic API for single or batch extraction.

よくある質問

What are the runtime requirements?

Python 3.8 or newer and the `pdfplumber` package. No other dependencies are required.

Does it require ground truth data to function?

No. Ground truth is optional—without it the tool uses heuristic-based scoring; with it, accuracy-based scoring is used.

What performance can I expect?

Overall confidence of 100%, exact match rate of 96.84% (153/158 populated fields), and processing speed of ~2‑3 seconds per document.

How does it handle missing or empty fields?

It distinguishes between fields that are legitimately empty and those that are missing due to extraction errors, assigning separate classification.

What extraction methods does it use?

Primary method is table‑based extraction; if that fails, a coordinate‑based fallback is used. The tool also leverages discovered patterns like fixed relative positions and consistent field sequence.
