Embodiment Construction
[0025] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.
[0026] like figure 1 Shown is the relationship between documents, topics, and vocabulary in the topic model. After the concept of "topic" is introduced into the data, the topic can be used as a "bridge" to connect documents and words. By observing the probability distribution between documents and topics and the probability distribution between topics and words, it can be obtained through related mathematical models. The distribution of subjects. When obtaining the relationship between topics and words, the degree of word co-occurrence relationship will affect the accuracy of the observation results, and this accuracy will further affect the quality of the final topic model. For long texts, there are enough word co-occurrence relationships as support during observation, while short texts lack suf...
