News event information induction method

Abstract

The invention discloses a news event information induction method, which comprises the following steps: collecting news materials, and creating a news library; obtaining all news texts of the target event from a news library, carrying out heat analysis, obtaining an inflection point news text, extracting event information in the inflection point news text, and storing the event information; the method for obtaining the news text of the inflection point comprises the following steps: obtaining the news text of the inflection point, counting the hot values of all the news texts, sorting according to the time sequence of news text release, constructing a curve graph of the hot values changing along with time, taking the news texts corresponding to all the maximum points of the curve graph, namely the inflection point news text, and enabling the hot values to be the sum of the page view of the news and the independent visitor volume of the website. According to the method disclosed by theinvention, the development situation of the news event is accurately reflected by selecting the news text, namely the inflection point news text, when the target news event is at the key node for abstract analysis and processing.

Description

technical field [0001] The invention relates to the field of information extraction, in particular to a news event information induction method. Background technique [0002] In recent years, with the rapid development and popularization of computer and information technology, people rely more and more on the Internet to collect information about target news events. Although the previous information extraction systems can help users retrieve a large amount of target information to a certain extent, due to the shackles brought about by the era of information explosion, users often directly retrieve a large number of relevant information surrounding the target event. In order to obtain useful information, the user needs to further filter the information; in addition, the event is in a dynamic development with the change of time, and it is difficult for the existing information extraction system to search for the target event. Trends are emerging, which inevitably brings a lot...

Although the previous information extraction systems can help users retrieve a large amount of target information to a certain extent, due to the shackles brought about by the era of information explosion, users often directly retrieve a large number of relevant information surrounding the target event. In order to obtain useful information, the user needs to further filter the information; in addition, the event is in a dynamic development with the change of time, and it is difficult for the existing information extraction system to search for the target event. Trends are emerging, which inevitably brings a lot of trouble to the process of analyzing target events for users
