Method and system for extracting data from documents and automatically modifying data item of the extracted data based on guidance retrieved from feedback file

Abstract

Improved techniques for extraction of data from documents, namely, from images of documents, so as to better enable software automation. The software automation can, for example, be provided by software robots of RPA systems. The improved techniques can provide automated feedback-based modification of data extracted from an image of a document through use of previously used validation guidance provided by a user in validating extracted data from a same or similar document. In one embodiment, the automated feedback-based modification can locate an appropriate feedback file through use of document fingerprints and document clusters. Then, guidance from the appropriate feedback file can be used to automatically modify at least a portion of the data extracted data from the image based on the guidance retrieved from the feedback file. Advantageously, the improved techniques can reduce the need for user participation in validation of data extracted from images of documents, and yield greater and more accurate automated data extraction.
