There are a range of models, articles and information available which extract keywords from unstructured documents. Examples are Spacy, POS tagging, NER, entity extraction etc
What I am looking for is key value pair extraction and not able to find much relevant articles or models or even datasets. Few examples of key value pairs are:
Name : Sandeep
Company Name: Sandeep
Total Amount $10000
or INV | INV110011
There can be a range of formats in which key value pairs can come. In above examples, person name and company name is same, and without much context models like spacy etc get confused.
Can someone please point to some models or information or articles or datasets which are trying to extract this information.
