The invention requests to protect a text abstract generation system and method based on adversarial learning and a hierarchical neural network, and belongs to the field of text abstracts of natural language processing. The system comprises a discriminator module, a preprocessing module, a word embedding module, a sentence embedding module, a generation module and an adversarial learning module. According to the invention, on the basis of an encoder decoder model (Seq2Seq), a new hierarchical division model is provided. An encoder part of the Seq2Seq is divided into a word embedding layer and asentence embedding layer, and an enhanced memory mechanism is introduced into each layer, so that the model can better understand text meanings, adversarial learning is introduced during decoding, arecognizer is arranged to recognize standard representation and fuzzy representation, the distance between the standard representation and the fuzzy representation is shortened, and meanwhile, learning is supervised to prevent the standard representation and the fuzzy representation from approaching, confrontation is formed, and when confrontation is balanced, an optimal generation result is found, so that the text abstract generation accuracy is improved.
