Language Processing Tool

Language Processing Tool is a Python package that processes PDFs and detects languages in documents. It supports both text-based and scanned PDFs using OCR.

Installation

You can install the package from PyPI using:

pip install language-processing-tool

Features

• Extracts text from PDFs (both text-based and scanned).
• Uses OCR (Tesseract) for image-based PDFs.
• Detects the dominant language and provides a language distribution.
• Supports batch processing of multiple PDFs.
• CLI and programmatic usage available.

Usage

In Python Code

To use this package in your Python script:

from language_processing_tool.process_pdfs import process_pdfs, process_single_file

# Process a single PDF file
print(process_single_file("/path/to/file.pdf"))

# Process multiple PDFs from a directory (using CSV input)
process_pdfs("/path/to/input_folder/", "pdf_files.csv", "/path/to/output_folder/")

Command Line Usage

After installing the package, you can use the CLI tool:

Process a Single PDF

process-pdfs /path/to/file.pdf

Batch Processing (Using CSV)

process-pdfs /path/to/input_folder/ /path/to/csv_file.csv /path/to/output_folder/

CSV File Format

The CSV file should contain a column named filename, listing the PDF filenames (without extensions). Example:

filename
document1
document2
document3

Make sure the corresponding PDFs (document1.pdf, document2.pdf, etc.) are in the specified input folder.
