Automating Document Processing in the Automobile Value Chain
Until the early 2000s, archiving paper documents were a common practice. As technology advanced, digital tools such as spreadsheets and email replaced the need for physical documents.
However, the data in these documents still had to be manually entered, leading to time-consuming and error-prone processes. It can result in fragmented workflows that are more challenging to manage than the simpler filing systems of the past, especially considering the complexity and high volumes of documents and data generated across the automotive value chain.
Traditional template-based Optical Character Recognition (OCR) methods provided some relief by extracting all text from the documents. However, there was no differentiation based on relevance or importance. Taking the required information from this extracted text still required human effort, adding to the overall workload.
The next generation of OCR, known as zonal OCR, improved upon this by extracting specific data from predetermined zones or areas of the documents according to pre-set rules. While this enhanced the efficiency to some extent, it still relied on predefined templates and lacked adaptability to varying document layouts.
Recently, OCR tools like Nanonets have evolved to incorporate artificial intelligence (AI) and machine learning (ML). These advanced OCR solutions can intelligently convert text into categorized data, recognizing patterns and structures within the documents.
They can also detect and rectify errors during the conversion process. It will further enhance accuracy and reliability.
