1. A document processing method comprising: receiving an input document which includes an abstract and a main body within the input document; storing the input document in memory of a computer system; identifying the abstract and the main body of the input document; for each sentence of the abstract of the input document, comparing the sentence with sentences of the main body of the input document using textual entailment techniques to identify whether the sentence of the abstract entails a sentence in the main body of the input document, the textual entailment techniques including identifying one-directional paraphrasing, wherein the entailed sentence in the main body need not entail the sentence of the abstract; generating links between the entailing sentences of the abstract and the corresponding entailed sentences of the input document; and outputting the generated links; wherein at least one of the comparing and link generation is performed with a computer processor.
