Abstract

The invention discloses an event retrieval method and device, computer equipment and a storage medium. The method can comprise the following steps: training to obtain an identification model for identifying whether two event descriptions correspond to the same event or not; forming an event vector extraction service based on the identification model, wherein the event vector represents understanding of the identification model for event description; according to the event vector extraction service, respectively obtaining event vectors corresponding to event descriptions to be retrieved and event vectors corresponding to event descriptions of events in an event library; and according to the obtained event vector, determining an event matched with the to-be-retrieved event description in anevent library. By applying the scheme of the invention, event retrieval based on event description can be realized, and the accuracy of a retrieval result is improved.

Description

【Technical field】

[0001] The invention relates to computer application technology, in particular to an event retrieval method, device, computer equipment and storage medium. 【Background technique】

[0002] In some scenarios, event retrieval is required, such as retrieving the corresponding event (same event) from the event library according to the event description provided by the user or appearing in the text, so as to facilitate text understanding or information recommendation.

[0003] An event is a special entity that exists objectively, but it is different from ordinary entities. It is more complex and has more diverse descriptions. The event descriptions of two identical events may be very different, and the event descriptions of two different events are different. Probably very similar.

[0004] In view of the above problems, how to perform event retrieval according to the event description, there is still no better way to implement it. 【Content of invention】 [0...
