Abstract

The invention provides a method and equipment for detecting area events based on short text data. The method comprises the following steps of obtaining to-be-processed short text data, wherein the to-be-processed short text data comprises position information; according to the position information, selecting sample text data corresponding to the preset position from the short text data; respectively segmenting words of the selected sample text data, and calculating the weight of each word in the sample text data; according to the weight of each word in the sample text data, building a sample text-word matrix corresponding to the sample text data; decomposing the sample text-word matrix, and determining the event of each sample text according to the decomposed sample text-word matrix. The method solves the problem of the prior art that the information of the short text data cannot be effectively processed for induction and classification.

Description

technical field [0001] The invention belongs to the technical field of data mining, and in particular relates to a method and equipment for detecting regional events based on short text data. Background technique [0002] With the vigorous development of Internet technology, more and more users publish various news or express personal opinions on some social phenomena through social networking platforms such as forums and microblogs. Due to its unique communication services, such as convenience, immediacy and ease of use, microblog allows users to respond quickly and disseminate information content without restriction, and has been more and more widely used. Hundreds of millions of users use short text data to transmit and comment on Weibo. While the explosive data information brings unprecedented value, it also brings huge challenges to Internet security detection and analysis. Massive data Effective event mining of information has become the main research problem of vario...
