| Back to ToCNews event elements extraction is a main task of information extraction. For news event correlation between sub-events, this paper proposes a kind of undirected graph model of news event element extraction merging associations of event elements. Firstly, splitting the news to multiple sub-event and extracting event elements. Then, the correlation between event elements and news events was analyzed, a undirected graph by extracting the correlation based on news event elements as node was established, and we transferred news event element extraction into a weighted undirected graph node calculation problem. At last, We conducted event elements extraction experiments. And comparing the experimental results show that the proposed method has good effect, correlation of sub-event can effectively improve the effect of extracting elements of news events. | |
