Method for automatically generating Chinese couplets by using natural language processing technology

Abstract

The invention discloses a method for automatically generating Chinese couplets by using a natural language processing technology. The method comprises the following steps: acquiring and processing a first line-second line data pair, a keyword-first line data pair and a horizontal streamer-first and second line data pair; performing word segmentation on all Chinese couplet data; building a machine translation model for realizing the Chinese couplet matching function, and training the model by using first line-second line data; reordering the model output according to rhymelevel and oblique tone rules, performing forced truncation on the output with a repeated translation phenomenon in the couplet matching process, and evaluating the model output; building and training a text generation model, and automatically adjusting the length of the Chinese couplet generated by using a length penalty coefficient automatic adjustment strategy; and building a text classification model for realizing a horizontal streamer generation function and training the text classification model. According to the method, the function of very complete couplet task is realized, the semantic integrating degree between the first line and second line is very high, the level and oblique correspondence is accurate, and the generated Chinese couplet is very high in relevancy with the keyword and beautiful in artistic conception.

Description

technical field [0001] The invention relates to the related tasks of applying machine translation technology, text generation technology and text classification technology to couplets, and specifically relates to a method for automatically generating couplets by using natural language processing technology. Background technique [0002] As research on natural language processing such as machine translation technology, text generation technology, and text classification technology becomes more and more popular, many scholars and technicians try to apply it in daily life. Couplets are a good example. [0003] The relatively mature "automatic couplet system" is a computer automatic couplet system developed by the Natural Language Computing Group of Microsoft Asia Research Institute. When the user gives an upper couplet, it can automatically provide several lower couplets for the user to choose; and when the user confirms a couplet, it can also generate several four-character ho...

Problems solved by technology

Through personal experience of this system, I found that this system can provide users with a better user experience by providing a direct method and a word segmentation method when linking the next link, but there are still some problems in the semantic coordination of the above two methods; At the same time, in many cases, the relationship between the horizontal batch and the upper and lower couplets is not close enough; in addition, the length of the couplets is limited to 10 characters, and cannot contain punctuation

There is also a crude automatic couplet system in the existing technology. Compared with the Micro
