Natural language processing techniques for generating a document summary

Abstract

A system for generating a summary of a text document is disclosed. In some examples, the system includes a processor configured to generate an initial summary of an original document. The initial summary includes a selection of extracted sentences copied from the original document. For each extracted sentence of the initial summary, the processor processes the extracted sentence to generate an abstracted sentence, and generates vector representations of the extracted sentence, the abstracted sentence, the original document, and the current summary. The vector representations are then input to a decision network to compute an editing decision. The editing decision is selected from a group of possible decisions that includes a decision to add the extracted sentence and a decision to add the abstracted sentence. The processor also updates the current summary based on the editing decision.
