Embodiment Construction
[0050] The present invention will be further described below in conjunction with specific examples.
[0051] Such as figure 1 As shown, a method for implementing a question answering system based on deep learning and topic models provided in this embodiment includes the following steps:
[0052] Step S1. First, input the question sentence into the Twitter LDA topic model to obtain the topic type of the question sentence, and extract the corresponding topic words, and represent the input question sentence and the topic words as word vectors. The specific process is as follows:
[0053] First, the topic words are extracted by the Twitter LDA topic model. First, the question and answer need to be composed of a question-answer pair {post, answer}. At this time, the question-answer pair is a short text that meets the requirements of the Twitter LDA topic model. The topic model assumes that each {post, answer} It is classified into a certain topic, and the words in the original que...
