Embodiment Construction

[0023] figure 1 It is a flow chart of the analysis method of the keyword-based event evolution process provided by the embodiment of the present invention. According to the microblog information searched by keywords, the embodiment of the present invention counts the number of microblogs, and provides an analysis method for event evolution process based on keywords. The specific steps of the method are as follows:

[0024] Step S101, counting the number of search results in each time period, and obtaining a sequence in which the number of search results changes with the time period;

[0025] Before the statistics of the number of search results in each time period, it also includes:

[0026] Searching according to keywords and obtaining search results related to the keywords, the search results including time information;

[0027] The statistics of the number of search results in each time period include:

[0028] Count the number of search results in each time period accor...

Abstract

The embodiment of the invention provides an analysis method and an analysis system based on an event evolution process of key words. The method comprises the steps of counting the quantity of search results within all time quanta, so as to obtain a sequence that the quantity of the search results changes along with the time quanta; performing peak detection on the sequence, so as to obtain at least one peak window; performing text analysis on the search result corresponding to the peak window, so as to obtain peak description; displaying the sequence that the quantity of the search results changes along with the time quanta, and displaying the peak description in a peak position. According to the analysis method and the analysis system of the embodiment of the invention, the sequence that the quantity of the search results changes along with the time quanta is counted, and the sequence that the quantity of the search results changes along with the time quanta and the peak description are displayed, so that the trend that the microblog information quantity changes along with time is shown, the evolution process of an event related to the key words can be shown by the trend that the microblog information quantity changes along with time, a user can know about main contents of microblog information without reading microblog contents in detail according to the peak description, and the information quantity displayed by the search results is increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, in particular to a method and system for analyzing event evolution process based on keywords. Background technique [0002] With the development of computer technology, microblogging software, as an important source of information acquisition, has become a widely used social software. [0003] In the prior art, the microblog software performs a matching search through the keyword input by the user, and displays the searched microblog information closely related to the keyword on the user terminal. [0004] Due to the time attribute of microblog information, the existing microblog information display results cannot show the trend of microblog information changing over time, resulting in a low amount of information displayed in the search results, and the evolution process of events related to keywords cannot be displayed . Contents of the invention [0005] Embodime...
