Pre-processing involves the automated cleaning, organizing, and structuring of uploaded files to prepare the documents for data extraction. Key actions include:

• Invalid File Handling: Identify issues that mean a document cannot be processed, such as not enough text found in the document, unsupported file types, corrupted document and password protection
• File Format Conversion: Converting file formats (e.g., images, PDFs with embedded data) into PDF format suitable for processing.
• De-duplication: Workspaces can be configured to identify and reject documents that have already been processed. See here for more information.
• OCR (Optical Character Recognition): Extracting text from scanned or image-based documents using advanced OCR technology, ensuring high accuracy for all document types and formats. See here for more information.
• Language Detection: Automatically identifies the language of the document to ensure high accuracy extraction.

Importance of Pre-Processing

By ensuring documents are well-prepared before extraction, pre-processing:

• Reduces the likelihood of errors in later stages.
• Improves the speed and accuracy of data extraction.
• Enables the seamless handling of various document types and formats.
