Abstract

The invention discloses a question generation method. The method comprises the steps of preprocessing reading understanding data in a reading understanding data set; inputting question generation datainto an encoder, and obtaining the hidden layer state of the encoder; inputting a question corresponding to the question generation data into a decoder, and obtaining a hidden layer state of the decoder; determining the generation probability of words in a preset dictionary based on the hidden layer state of the encoder and the hidden layer state of the decoder; determining the word generation probability at the current moment according to the context vector of the current moment, the hidden layer state of the decoder and the input of the decoder; and determining probability distribution of the words according to the generation probability of the words and the word generation probability at the current moment. According to the method, the problem of unsmooth generation caused by the factthat words which are not in a dictionary cannot be generated depending on a fixed dictionary in the prior art is solved.

Description

Technical field [0001] The present invention relates to the field of artificial intelligence technology, in particular to a question generation method. Background technique [0002] Problem generation plays an important role in the development of human intelligence and the development of artificial intelligence systems. In many application areas, the demand for problem generation is growing rapidly. The question generation system is designed to generate various questions based on a given text. In the field of education, asking good questions is crucial to assessing students’ knowledge and motivating self-learning; in dialogue systems, question generation is a very important skill of robots, such as helping robots start cold or getting user information to proceed. Better communication; in reading comprehension, question generation can help people automatically generate questions, thereby saving a lot of manpower, material and financial resources to label data. [0003] The existi...
