Not All OCR Solutions Are Created Equal

Understanding documents is extremely valuable when setting up a successful AI OCR (Optical Character Recognition) solution because not all OCR solutions are created equal. OCR technology extracts text and information from images or scanned documents, and its effectiveness depends on understanding the quality and relevance of the documents being processed.

OCR Features

Document Variability

Documents can vary widely in terms of layout, fonts, languages, and formatting. Understanding the types of documents you will be processing helps in customizing the OCR system to handle these variations effectively.

Preprocessing

Knowing the documents allows you to perform preprocessing tasks such as image enhancement, noise reduction, and deskewing, which can significantly improve OCR accuracy. Different document types may require different preprocessing steps.

Language and Script Recognition

If your documents contain multiple languages or scripts, understanding the document content helps in configuring the OCR to recognize and process each language correctly.

Layout Analysis

Understanding the document structure and layout enables the OCR system to identify headers, footers, tables, and other structural elements. This is crucial for preserving the document’s semantic meaning during OCR.

Field Extraction

In the case of accounts payable (AP) automation, you do not need to extract text from the entire document but only specific fields or regions (e.g., extracting customer names, dates, and amounts from invoices). Understanding the document layout helps in defining these regions for extraction.

Error Handling

Recognizing common errors or variations in the documents allows you to implement error-handling mechanisms, such as verifying extracted data against predefined patterns or rules.

Training and Tuning

Training and fine-tuning the OCR model often require labeled data for supervised learning. Understanding the documents helps in creating training datasets that reflect the real-world variations present in your document collection.

Post-Processing

After OCR, you may need to perform post-processing tasks, such as data validation, or entity recognition. Knowing the context of the documents aids in designing effective post-processing routines.

Performance Metrics

Understanding the documents helps in setting realistic performance metrics for your OCR solution. Different types of documents may have varying levels of difficulty, and you need to assess OCR accuracy accordingly.

Scalability and Maintenance

Knowing the document types and potential future changes in document formats allows you to design a scalable and maintainable AI-assisted OCR solution. You can plan for updates and improvements based on your understanding of the documents.

What does a successful OCR solution look like?

Many companies are disappointed when the promises of OCR fail to deliver a return on investment. This often occurs because accuracy rates are too low. Outputting bad data can result in paying vendors the wrong amount or even paying the wrong vendors altogether! Additionally, the high costs of post-processing clean-up make it clear why there is a lack of ROI. However, the technology isn’t the problem, it’s the process.

For a successful AI-assisted OCR program to deliver an acceptable ROI, the first step must be a thorough examination of the target documents, process, and expected results. Utilizing “real-world” documents (not random test documents), a series of tests can provide data on expected results giving decision-makers the information needed to determine if the investment will provide the ROI needed. In summary, understanding the documents and process you’re working with is fundamental to the success of your AI OCR solution.

Conclusion

With AI-assisted technology, the tools are in place, but can they deliver the savings to justify the investment? Since not all OCR solutions are created equal, be sure to choose a solution provider that helps you do your research and understand your documents. Let your solution partner help you tailor the AI-assisted OCR system to the specific needs of your document collection, resulting in higher accuracy and efficiency in text extraction and data processing.
