Abstract

The invention provides a news event element extracting method. The news event element extracting method comprises the following steps: identifying names contained in a news text and extracting name characteristics; calculating the possibility that the names become protagonists of news events according to the extracted name characteristics; identifying the protagonists of the news events based on the possibility. In some embodiments, the method further comprises the following steps: extracting viewpoints and speaking sentences of the protagonists related to the news events and extracting locations and time of the news events. According to the news event element extracting method, the problems that the cost for manually analyzing and sorting news information is high and the efficiency is low can be overcome; meanwhile, support is provided for superior-layer application of news event searching, news reporting and tracking and the like.
