Abstract

The invention provides a network hot-point topic discovery method and system. The method includes: extracting hot words from a text corpus of a preset time period; combining two hot words into the same set when correlation of the two hot words is greater than a first preset threshold value; calculating a co-occurrence degree between every two hot word sets, and merging the two hot word sets when the co-occurrence degree between the two hot-word sets is greater than a second preset threshold value; and calculating a co-occurrence degree between every two hot words in each hot word set, carryingout counting of the co-occurrence degree of each hot word, and selecting multiple hot words, of which co-occurrence degrees are arranged in the forefront, to use the same as names of corresponding hot-point topics. The method and the system carries out discovery operations of the network hot-point topics from an angle of the hot words, and more accord with definition of the hot topics; and ensurehigh correlation of internal information of the hot-point topics through combination of the related hot words and the co-occurrence hot-word sets at the same time, can realize accurate discovery of the network hot-point topics at the same time, and facilitate an effect that a user intuitively identifies the network hot-point topics.

Description

technical field [0001] The present invention relates to the technical field of text information processing, and more specifically, to a method and system for discovering network hot topics. Background technique [0002] With the increasing popularity of the Internet and the exponential growth of network resources, the traditional manual information processing methods can no longer meet the requirements of large-scale information acquisition. Therefore, it is necessary to monitor and analyze network public opinion through new information technology to meet Information needs of users in various industries. By discovering hot topics on the Internet, you can keep abreast of the development trends of various industries and monitor the network information dynamics of various industries in real time. Tracking hot topics will help relevant departments to grasp the ideological trends in the network in a timely manner, conduct correct guidance and analysis of public opinion, and main...
