Abstract

The invention provides a specific-group discovery method based on news data and related comment information. The method comprises the following steps: collecting the news data information and the related comment information in targeted media; classifying the news data information according to text contents thereof to obtain different class clusters; using the class cluster, which contains the newsdata information with a highest comment number, as a sample to acquire all comments of news data messages in the class cluster and users, who publish the comments, according to the related comment information; obtaining keywords through carrying out word segmentation on contents of all the comments, and using the keywords, of which occurrence frequency is higher than a threshold value, as high-frequency words; adopting a vector space model to represent the contents of the comments, clustering text of the comments through an agglomerative hierarchy, and obtaining comment user reference features of different class clusters according to a clustering result; and identifying a specific group according to the high-frequency words and the comment user reference features. A robot account can be quickly and intelligently discovered through analyzing the comment information contents, and thus processing is carried out in time.
