porosdata-processor 0.3.0

Academic document intelligent cleaning pipeline for AI for Science, ensuring MinerU parsed data meets LLM input standards

PorosData-Processor

Python Version License: MIT

PorosData-Processor cleans MinerU-derived scientific document text for downstream LLM and data-mining workflows. It normalizes text without breaking LaTeX formulas, repairs OCR errors, cleans up citations and numbering, and optionally evaluates token efficiency.

Installation

pip install porosdata-processor

Optional extras:

# Token evaluation support
pip install "porosdata-processor[eval]"

# Streaming JSON parsing for large files
pip install "porosdata-processor[batch]"

Python 3.8+ is supported.

What The Package Does

• Cleans scientific text while preserving LaTeX formulas via a placeholder-based protect/restore mechanism (Shield).
• Normalizes whitespace, Unicode, citations, numbering, and repairs OCR errors.
• Provides a Python API for single-text processing.
• Provides a CLI for batch processing MinerU *_content_list.json files.
• Optionally computes token-efficiency statistics when transformers is installed.

Python API

from porosdata_processor import TextCleaner

cleaner = TextCleaner()
result = cleaner.clean("Recent studies 【1】 show α-phase stability.")
print(result)

Example output:

Recent studies ref[1] show \alpha-phase stability.

Custom pipeline example:

from porosdata_processor import TextCleaner

cleaner = TextCleaner(
    pipeline=[
        "unicode_normalization",
        "patterns_cleaning",
        "normalize_whitespace",
    ]
)

result = cleaner.clean("Text   with   extra spaces")
print(result)

Optional evaluation mode:

from porosdata_processor import TextCleaner

cleaner = TextCleaner.with_tokenizer_evaluation("gpt2")
result = cleaner.clean("Recent studies 【1】 show α-phase stability.", eval_mode=True)
print(result["processed_text"])
print(result["evaluation"]["overall"]["compression_rate"])

CLI Batch Processing

The CLI recursively scans the input directory for MinerU *_content_list.json files and writes cleaned JSON outputs plus processing_report.json to the output directory.

porosdata-processor run \
    --input-dir data/raw \
    --output-dir data/processed \
    --max-workers 4

Enable optional features:

porosdata-processor run \
    --input-dir data/raw \
    --output-dir data/processed \
    --enable-evaluation \
    --max-workers 4

Common flags:

• --input-dir: input directory containing MinerU outputs
• --output-dir: output directory for cleaned files
• --enable-evaluation: enable token-efficiency evaluation
• --max-workers: set the number of worker processes
• --force-reprocess: ignore existing outputs and re-run processing
• --memory-limit: memory limit in MB
• --log-level: DEBUG, INFO, WARNING, or ERROR
• --heartbeat-seconds: emit runtime heartbeat logs every N seconds

Scope And Input Format

• Batch processing is designed for MinerU-generated JSON content lists, not for generic JSONL, Parquet, or HDF5 datasets.
• The primary public API is TextCleaner for string-based cleaning and the porosdata-processor CLI for directory-based processing.
• Commands such as audit, sample-validate, and delivery-gate are also available from the CLI, but they are intended for internal data-governance workflows.
