Practical applications in using the OCR tool for translation

One of the most straightforward applications of OCR in translation is digitizing printed documents. Translators no longer need to type out texts from books or papers manually; instead, they can scan documents directly into OCR systems, which convert them into editable formats. We have written a couple of tips and advice on how you can get started in using OCR software:

Step 1: Choose the right OCR software

Research and Select: Assess various OCR tools that cater specifically to your language pairs and document types. Consider features like language support, accuracy, ease of use, and integration capabilities.
Trial Versions: Before purchasing, try trial versions to check compatibility with your typical translation tasks.

Step 2: Prepare documents for scanning

Quality of Original Documents: Ensure documents are in good condition—clean, without folds or smudges, as imperfections can affect OCR accuracy.
Proper Scanning Equipment: Use a reliable scanner that can handle the document type and size. Set it to a high resolution to capture clear images of the text.

Step 3: Optimize OCR settings

Language Settings: Configure the OCR tool to recognize the languages and specific scripts in your document.
Resolution and Format: Adjust the resolution settings if needed (generally, 300 DPI is sufficient for clear text). Choose the appropriate file format for output, like PDF or DOCX, depending on your further processing needs.

Step 4: Perform OCR on the document

Running OCR: Feed the scanned images into the OCR software. Monitor the process to ensure that the software accurately recognizes the text.
Review and Edit: Initially, review a few pages to confirm that the text is being correctly recognized. If errors are frequent, consider rescanning at a higher quality or adjusting OCR settings.

Step 5: Edit and format the translated document

Manual Review: Go through the OCR output meticulously to correct any misrecognition or formatting issues. Pay special attention to proper nouns, technical terms, and layout.
Formatting: Adjust the document’s formatting to match the original layout or to suit the translation’s purpose. This includes aligning text, adjusting fonts, and reinserting non-text elements like images or tables.

Step 6: Translate the text

Translation Tools: Utilize translation management software or CAT tools to import the OCR-processed text. These tools can help maintain consistency and speed up the translation process.
Contextual Understanding: Ensure that the translation respects the context and nuances of the original text. This might require additional background research or consultation with a subject matter expert.

Step 7: Quality assurance

Proofreading: Have a second translator or an editor proofread the translated document to ensure it is free of errors and accurately conveys the original message.
Cross-verify: Check the final translated document against the original to ensure all text has been captured and correctly translated.

Step 8: Use feedback to improve

Collect Feedback: Gather feedback from clients or the end-users of the document to learn about any issues or areas for improvement.
Refine Processes: Use the feedback to refine your OCR settings, document preparation steps, and translation methods for future projects.

Challenges and solutions of using OCR scanning

Despite its benefits, OCR technology is not without its challenges, especially when dealing with complex scripts and layouts. Non-Latin scripts like Arabic or Mandarin, which include a wide array of characters and contextual variations, pose particular difficulties. Modern OCR software addresses these challenges with improved character recognition algorithms and better context understanding, reducing the error rate significantly. Accuracy remains a crucial issue. While OCR technology has advanced, errors still occur, particularly with older or damaged documents. Continued advancements in AI help mitigate these issues by refining the algorithms that OCR software uses to interpret and convert different fonts and styles.
