Abstract

The invention discloses a hot topic finding method. The method comprises the steps that web page data is obtained, and segmentation treatment is conducted on the web page data to obtain a treatment result; characteristic extraction is conducted on the treatment result to obtain characteristic factors; the characteristic factors are inputted to an LDA model to obtain the probability corresponding to each topic in the web page data; the topics with the probabilities larger than a preset value are regarded as hot topics. Therefore, according to the hot topic finding method, by conducting treatment and characteristic extraction on the web page data to obtain the characteristic factors, extracting the topics in the web page data and the probabilities corresponding to the topics through the LDAmodel and regarding the topics with the probabilities larger than the preset value as the hot topics, the efficiency of finding the hot topics is improved. The invention further discloses a hot topicfinding system, hot topic finding equipment and a computer-readable storage medium. The system, the equipment and the computer-readable storage medium can also achieve the technical effects.
