Event mining method and device

Abstract

The invention discloses an event mining method and device. According to the method, a plurality of reference texts can be extracted from a text data set; event classification is carried out on the reference texts to obtain an event text set, wherein the event text set comprises reference texts associated with a target event; clustering processing is carried out on reference texts in the event textset to obtain a clustered text set corresponding to sub-events, wherein the sub-events belong to the target event; a mapping relationship between the text quantity of a target text in the text data set and the search time of the target text is analyzed to obtain an analysis result, wherein the target text is a text belonging to the sub-event in the text data set; and periodic discrimination is performed on the sub-events based on the analysis result, and a periodic discrimination result is output. According to the method, automatic mining of periodic events can be realized, the accuracy of event mining results is improved, and the mining efficiency can also be improved.

Description

Technical field [0001] This application relates to the field of computer technology, in particular to an event mining method and device. Background technique [0002] With the rapid development of computer technology and network technology, the Internet plays an increasingly important role in people's daily life and work and study. People often search for various information through the Internet. Some specific activities or events occur at specific time periods each year, such as college entrance examinations, holidays, and some fixed annual seasons. Even though the exact dates of specific annual events may not be the same, they occur before, during, and after these events, etc. In different time periods, the search behavior of users on these events in search engines will show regular periodic characteristics, and product operators will operate these periodic events. [0003] In the current related technologies, generally based on manual experience, some typical periodic event wor...

Problems solved by technology

[0003] In the current related technologies, some typical periodic event words are generally collected based on artificial experience, so the efficiency of mining is too low, and the accuracy of mining results is relatively low
