Embodiment Construction
[0062] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0063] In an existing method for mining hot words, after matching the candidate word set with the hot word vocabulary, the N hot candidate words with the highest frequency are output as hot words. Due to the long update period of the hot word list, more hot words in the candidate word set are filtered by the hot word list, so that the mining range of hot words is small and the mining efficiency is low. In the embodiment of the present invention, consider and record the historical frequency of each candidate word in the candidate word set, calculate its frequency anomaly degree in conjunction with the current frequency of the candidate word, and mine hot words through the frequency anomaly degree, so that the hot word and hot word word of e...
