Abstract

The invention discloses a question generation method, comprising: preprocessing reading comprehension data in a reading comprehension data set; inputting the question generation data into an encoder, and obtaining a hidden layer state of the encoder; The question is input to the decoder, and the decoder hidden layer state is obtained; the generation probability of the word in the preset dictionary is determined based on the encoder hidden layer state and the decoder hidden layer state; according to the context vector at the current moment, the decoder The hidden layer state and the decoder input determine the word generation probability at the current moment; the probability distribution of the word is determined according to the word generation probability and the word generation probability at the current moment. The invention solves the problem that the existing technology relies on a fixed dictionary and cannot generate words that are not in the dictionary, resulting in unsmooth generation.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, and in particular, to a problem generation method. Background technique [0002] Problem generation plays an important role in both the development of human intelligence and the development of artificial intelligence systems. The need for problem generation is growing rapidly in many application areas. Question generation systems aim to generate various questions based on a given text. In the field of education, asking good questions is crucial for evaluating students’ knowledge and motivating self-learning; in dialogue systems, question generation is a very important skill for robots, for example, it can help the robot to cold start or get information from users to carry out Better communication; in reading comprehension, question generation can help people generate questions automatically, thereby saving a lot of manpower, material and financial resources to label data.
