Abstract

The invention belongs to the technical field of network monitoring, and particularly relates to a keyword generation method and device, a public opinion monitoring method and device, equipment and a medium. The method comprises the steps that environment corpus information is collected, corpus words are extracted from the environment corpus information, and a corpus word set is obtained; screeningthe corpus words contained in the corpus word set according to a preset noise corpus word library to remove the noise corpus words; and carrying out weight calculation on each corpus word in the corpus word set after the noise corpus words are removed, and gathering a preset number of corpus words with weights from high to low into a keyword set to be output. According to the keyword generation method provided by the embodiment of the invention, the keywords related to the environmental public opinion can be automatically generated by performing corpus word extraction analysis on the environmental corpus information, so that the keyword generation speed and comprehensiveness are improved, and the environmental public opinion monitoring efficiency and effect are improved.

Description

technical field [0001] The invention belongs to the technical field of network monitoring, and in particular relates to a method for generating keywords, a method for monitoring public opinion, a device, equipment and a medium. Background technique [0002] With the development of informatization and the rise of social networks, environmental pollution information is disseminated and discussed on the Internet through various channels such as Weibo, online forums, WeChat public accounts, and self-media platforms. Environmental conditions, environmental pollution, and safety supervision have broadened the channels for the government to understand environmental conditions and public opinion to a certain extent, but it has also increased the difficulty of government network public opinion monitoring. [0003] A keyword is usually a short, conclusive piece of content that can describe the topic information in a longer text. High-quality keywords can provide index information for...
