Embodiment 1
[0086] For each key time node, the device cuts the search words in the first statistical record of the key event node, weights the cut words according to their relevance to the topic, and selects a weight value exceeding a predetermined threshold The words are used as the description information of the key time node.
Embodiment 2
[0088] For each key time node, the device cuts the search words in the first statistical record of the key event node, weights the cut words according to their relevance to the topic, and selects a weight value exceeding a predetermined threshold , use the selected words to query matching articles from the included news database or library, and select at least one article from the queried articles as the event article of the key time node.
[0089] Due to the huge resource consumption caused by full mining at cold start, in order to solve this problem, according to another preferred embodiment of the present invention, the device further stores the first search word statistical data and the second search word statistical data. In this way, in addition to taking a lot of time to fully mine the historical log data when the system starts for the first time, it can effectively avoid repeated mining and calculation of the historical log data at each subsequent startup, reducing the ...
