Every organization wants accurate data to run its operations smoothly. Thus, we need to obtain data in an editable and structured format, but data entry without smart technology is a dead end. Time and manual efforts required for the task only make the process slower and inaccurate. 


The most popular technology for data extraction from physical (unstructured) documents is Optical Character Recognition (OCR). OCR helps automate business processes by saving time, cost, and efforts needed to extract relevant data and store them as searchable texts for easy access. 

How is Accuracy Rate in OCR Systems Measured?

Accuracy of any OCR related technology is measured by comparing the output with the source document. We count how many characters (or words) were recorded correctly out of the total characters (or words). For example if an OCR technology recognizes 950 out of 1000 characters correctly, then its accuracy rate will be 95%. 

Moving Beyond Generic OCR

According to a study done by the U.S. Government Printing Office, OCR scanners have an accuracy rate between 90%-98%. They are even able to capture all the image data from older, discolored documents. This means in a page of 1000 characters, 980 to 990 characters can be accurate. 


Unfortunately, this only holds for extracting the entire text from any image, but when it comes to interpreting the meaning of the extracted strings from non-standardized and free-flow documents like invoices, account statements, loan documents, etc. the technology falls miserably short. Moreover, traditional OCR systems provide output in a non-structured format, which leaves a lot of work for data entry employees. Both these issues can be addressed by using standard templates for such documents, but it’s beyond a company’s power to control the format and layouts/ text used in all documents e.g. invoices of its vendors. Hence we need a more efficient solution that can solve these issues without requiring a fixed template. 


The accuracy rate is critical for unique documents in operations such as accounting, where inaccurate data can result in legal expenses, losses, and audit issues. Invoices, purchase orders, tax receipts heavily rely on extracting specific data and tagging it so it can be synced directly with accounting and ERP solutions.


While OCR scanning helps in digitization with a high success rate, enhancing the technology with Artificial Intelligence and Machine Learning means the system is now equipped to deal with documents in any template, language, or text style as well as returning the output in editable and structured (or semi-structured) format.
