Abstract

The embodiment of the invention provides a network news hotspot mining method and device, and the method comprises the steps: carrying out preprocessing of original network news data to acquire network news information; extracting text feature vectors in the network news information through a bilingual LDA topic model and a bilingual LSA model; and according to the text feature vector in the network news information, performing parallel operation on a Spark platform by utilizing a Single-Pass clustering algorithm to obtain news hot topic information. According to a text feature extraction method based on combination of the bilingual LDA model and the bilingual LSA model, entity information with high distinction degree for each topic is contained in the topic model; according to the networknews hot spot mining method, the semantic relation between text contexts is also considered, and the Spark-based parallelization Single-Pass clustering algorithm is utilized, so that the clustering speed is increased, and the network news hot spot mining is more effectively and accurately realized.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for mining network news hotspots. Background technique [0002] News topic detection and tracking is an important research branch of TDT (Topic Detection and Tracking) technology. TDT technology is based on the latest research results of natural language processing, aiming at the news data flow in the network, according to the theme and semantic characteristics of the news, they are automatically Divide it into different topics and display it to users in a clear and clear visual form. At the same time, track the dynamic development trend of the topic according to the change of time. [0003] However, in the prior art, the mining of network news hotspots often has the problems of poor computing performance and low accuracy. With the rapid increase of network information, the public's demand for effective access to news information is becoming mor...
