Problems solved by technology

However, due to the lack of pertinence to regions and industries, the hot events excavated by this method are sometimes not what users care about
In addition, hotspot mining for all information will consume more time, and the amount of calculation is very large, consuming more system resources

Abstract

The invention discloses a method and equipment for mining hot events based on regions and industries. The method includes: acquiring documents from a network; performing word segmentation on each document, and determining weight of each segmented word in each document; determining keywords of each document according to the weights; performing region and industry division on content of each document; correlating the keywords of each document with the content belonging to the same region and the same industry to form keyword groups, and determining weight of each keyword group; determining hot events in the region and the industry according to the weights of the keyword groups. Due to the fact that mining is performed targeted to specific regions and specific industries, hot events in the regions and industries that users are concerned about are provided for the users according to user requests. Furthermore, mining time can be reduced, calculated amount is reduced, and system resources are saved.

Description

technical field [0001] The present invention relates to the field of information search, in particular to a method and device for mining hot events based on regions and industries. Background technique [0002] With the development of the Internet, more and more users publish various news and express their opinions through platforms such as forums, microblogs, and blogs. As a result, thousands of topics are generated every day on the Internet. How to dig out hot events from the massive information on the Internet will play a guiding role for users to understand the social development situation and grasp the dynamics of public opinion. [0003] Existing hot event mining methods obtain massive information from the network, and then mine hot events from the massive information. However, due to the lack of pertinence to regions and industries, the hot events mined by this method are sometimes not what users care about. In addition, hotspot mining for all information will cons...
