Abstract

The invention discloses an event similarity modeling-based event context acquisition method and system. The method comprises the steps of S1, acquiring information of corresponding events; S2, building a database according to the information of the events, and respectively storing the corresponding events according to the size of a certain time window D; S3, deeply mining data information in the database, building a vocabulary network model and an event base, and acquiring a corresponding motif structure to be stored in the event base; and S4, acquiring event context according to different event types. By the method, event similarity comparison can be performed on information of all news websites and comment information and the like of Wechat, microblog and forum, the information of a related event can be rapidly acquired, and the method has the characteristics of simplicity, fast event acquisition speed, high accuracy and the like.

Description

Technical field [0001] The invention relates to the field of event information mining and similarity extraction, in particular to a method and system for acquiring event context based on similarity modeling. Background technique [0002] Events are happening all the time in real life, and events form fragmentary text descriptions through human feelings, memory, and analysis. Today is an era of rapid development of the Internet and an era of endless information. News reading has become an indispensable habit or behavior for most netizens every day. At the same time, massive amounts of news are released by countless media every day. The media select important news and events of interest for reading, which has become the demand of most netizens. [0003] The existing Chinese patent application number 201510324990.9 is based on a microblog-based event context acquisition method and system. The method includes: acquiring original microblogs for events included in a predetermined topic ...
