I am new to machine learning and data science. I apologise if the question seems very basic. I have a requirement where I need to verify information submitted via a form with the corresponding official document. My approach till now has been to use google vision to extract text and use regex to extract necessary fields and compare with the form information. This is not always reliable because of the image quality and vision captures the noise as well.
Previously, I was thinking of just comparing each data file and search it in the text extracted and provide a metric of certainty.
I talked to one of my colleagues and he suggested using some for of supervised learning algorithm to process the documents, so that they automatically extract the key fields.
I want to ask would this method be simpler than my current approach. I am also worried about the scalability of my approach in event of minor changes in document formats.
I am looking for links for some articles or books related to this and answer to why using my own model will be better than just searching each word in a text.
Edit: The data can be imagined as a visiting card which contains the name of person, his office address, his contact number and the company's name. The problem here is different visiting cards can have different formats. Moreover the information is repeated twice: Once in English and the second in another language. For example , NAME : JANE DOE is followed by नाम : जेन डोए in next line. I only need the English name. The number of formats are constant but are high. Moreover, the address is not read together by Google Vision in most cases and using regex can become too complicated and case specific. I need to verify employee identity cards as proof that they are working for the company they claim to.
