Provided are a trending topic detection method, apparatus and device, and a medium, which are applicable to the technical field of the Internet. The method comprises: continuously acquiring topic data in an information sharing platform; when each piece of topic data is acquired, carrying out matching processing on the topic data and each word in a pre-set word library to output a plurality of word segmentation results; outputting a plurality of segmented words included in the word segmentation result with the highest matching degree as keywords corresponding to the topic data; updating, according to the keywords, summary information associated with the topic data; and presenting the keywords and the summary information so that a user learns about a trending topic at a current moment. By means of the solution, keywords corresponding to topic data can be determined, and summary information can be updated based on the keywords, such that a user can quickly learn about a trending topic on the information sharing platform according to the output keywords and the summary information.
Description
technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a burst topic detection method and burst topic detection equipment. Background technique [0002] On information sharing platforms such as Weibo, Twitter, and forums, based on the openness of the platform, users can share and forward various information anytime and anywhere. In a short period of time, if a large number of users share or forward the same information, the specific topic corresponding to the information will evolve into a hot topic. If these sudden topics are related to a specific company, they may have a huge influence on public opinion for the company. If an enterprise cannot discover and track unexpected topical events related to the company in time, it will miss the best time to eliminate the influence of negative public opinion, thereby reducing the soft power of the enterprise itself. [0003] However, in the prior art, it is difficult to qu...
