Before revision: We combine deep learning and Conditional Probabilistic Context Free Grammars ( CPCFG) to create an end-to-end system for extracting structured information from complex documents. For each class of documents, we create a CPCFG that describes the structure of the information to be extracted.
After revision: We combine deep learning and Conditional Probabilistic Context Free Grammars ( CPCFG) to create an end-to-end system for finding the most probable parse that represents the structured information to be extracted.
