Embodiment 1

[0053] figure 1 The flow chart of the event-oriented news presentation method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes the following steps:

[0054] Step 101: Obtain news data from a news source.

[0055] In this step, the interface provided by the news platform can be used to obtain news data at a certain time interval. The news platform here can be a news channel of any website, or news data newly collected by a search engine.

[0056] Step 102: Clustering the acquired news data based on content to obtain news events corresponding to each news cluster.

[0057] The content-based clustering adopted in this step can adopt the singular value decomposition method of the news-keyword matrix, and the specific clustering process can include:

[0058] First, after word segmentation and removal of stop words for the news summary in the obtained news data, keywords are extracted according to the TF-IDF of each word to form th...

Abstract

The invention provides a method and a device for news presentation facing events. The method comprises the following steps: acquiring news data from a news source; clustering the acquired news data according to contents, so as to obtain news events corresponding to each news cluster; judging the clustering state of a newly obtained news event to an existing news event in content and time, confirming that news events meeting clustering requirements of clustering states in content and time belong to the same news event, and presenting the news events belonging to the same news event in a merged manner; and confirming that incidence relation exists among news events which meet clustering requirements of clustering states in content but not meet clustering requirements of clustering states in time, and presenting the incidence relation among the news events with the incidence relation while presenting the news events. According to the invention, manual editing cost can be reduced; and the incidence relation among the news events is presented.

Description
