[0004] However, because the keywords or search terms of burst detection are relatively short, although some keywords or entities can be identified as bursts, it is impossible to dig out which event or which events caused it, and the event recall rate is low.
The clustering method and the method of combining clustering and burst detection, when performing clustering operations, the objects of the clustering are the texts of news or microblogs, which is easy to cause the problem of impure clusters and super large clusters , the accuracy of event detection is low

Embodiments of the invention provide an event discovery method and device, equipment and a storage medium. The method comprises the steps of obtaining a plurality of texts comprising target keywords;extracting phrases for independently describing event information from titles of the plurality of texts; clustering the extracted phrases, and clustering texts where the phrases belonging to the sameclustering cluster are located together to form an event. According to the event discovery method provided by the embodiment of the invention, the event discovery accuracy and the event recall rate can be improved.
Description
technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular, to an event discovery method, device, device, and storage medium. Background technique [0002] With the development of the Internet and the explosive growth of Internet information, everyone has to face the problem of information overload. When a user wants to follow a certain person or company, what the user has to face is a large amount of unorganized news information. If a large amount of information on the Internet can be organized at the granularity of "events" and presented to users, the time cost for users to obtain information can be greatly reduced. [0003] The main methods of current event discovery include three types: clustering method, burst detection method, and the method of combining clustering and burst detection. Among them, the clustering method is based on the preset similarity The degree calculation method clusters the te...
