Abstract

The invention discloses a free text generation method. The method comprises the following steps: S1, key words input by a user are combined into a character string; S2, the character string is encoded into a group of word vectors with the dimension being i through a first recurrent neutral network, and implicit vectors are generated according to the word vectors; S3, a candidate set of the t word is generated through a second recurrent neutral network according to the word vectors and the implicit vectors, the probability distribution vector of the candidate set of the t word is predicted, and t is larger than or equal to 1; S4, the word with the largest probability distribution in the candidate set is output as a predicted word Yt according to the text format, and all texts are generated through loop iteration. According to the text generation method, mapping information and semantic information of words are trained simultaneously, texts in various formats can be used for learning, the data sparseness problem is solved, and texts in any length and any sentence pattern can be generated.

Description

technical field [0001] The invention relates to the field of computer artificial intelligence, in particular to a method for generating free text. Background technique [0002] Automatic text generation is considered to be an important symbol of contemporary machine intelligence, because people need a strong imagination when creating text, the machine must be able to "learn" the way the article is written and "simulate" the creative ability of the human brain, so it is extremely difficult . There are two traditional methods of text generation, including statistical machine translation probability model (Statistical Machine Translation, SMT) and neural network model (Neural Networks, NN). [0003] The Statistical Machine Translation Probability Model (SMT) is a technology that uses a machine to translate a sentence to be translated input by a user to obtain a target sentence. Machine translation is based on the following principle: the translation of the source sentence t...
