Embodiment

[0245] Such as figure 1 As shown, a general flowchart of a method for automatically extracting news-based event evolution relations, the news-based automatic extraction method for event evolution relations includes the following steps:

[0246] News information preprocessing: Segment the input news, perform part-of-speech tagging and remove stop words, and extract the feature words in the comments to establish the structured data of the news;

[0247] News lead extraction: A news lead is a sentence that expresses the central idea of ​​the news in a few sentences at the beginning of the news. Extracting news leads is used to extract news time and event keywords of news documents. The invention proposes a method for extracting news leads;

[0248]Time extraction of news events: News has obvious timeliness, and each event news has a definite time point or time period of occurrence. Extracting the time of news plays an important guiding role in the analysis of news evolution. ...

Abstract

The present invention discloses an automatic extracting method of event evolving relationship based on news. The method comprises: preprocessing news information, extracting news leads, extracting news event time, extracting events, extracting event keywords, and analyzing event evolving relationship. The present invention further discloses an automatic extracting system of the event evolving relationship of news. The automatic extracting system comprises a news information preprocessing module, a news lead extracting module, a news event time extracting module, an event extracting module, an event keyword extracting module, and an evolution relationship analyzing module. Through the adoption of the automatic extracting method and system, disclosed by the present invention, the graph of event evolving relationship is more reasonable, and the relationship between events is more clear; the automatic extracting method and system have the advantages that partial problems in the present field of news evolution analysis are solved, so that the evolution analysis achieves better effects, and users can conveniently know the evolutionary skeleton of the whole news topic.
