Early warning event graph construction method and device, equipment and storage medium

Abstract

The invention discloses an early warning event graph construction method, and relates to the field of big data, and the method comprises the steps: obtaining text information for event graph construction when an event graph construction instruction is received; performing event acquisition on the text information to obtain at least one piece of first event information corresponding to the text information and an early warning label corresponding to the at least one piece of first event information; screening the at least one piece of first event information to obtain at least one piece of second event information for event atlas construction; determining a hierarchical relationship between the at least one piece of second event information according to the feature information contained inthe at least one piece of second event; and storing the at least one piece of second event information in a corresponding graph database according to the hierarchical relationship so as to complete construction of an event graph. The invention further provides a device, computer equipment and a storage medium. When the event atlas is constructed, the quality of the event atlas is improved.

Description

technical field [0001] The present application relates to the field of big data technology, and in particular to a method, device, computer equipment and storage medium for constructing an early warning event graph. Background technique [0002] With the rapid popularization of the Internet, all kinds of social network media, such as blogs, wikis, podcasts, forums, social networks, and content communities, have flourished. These social media have become the most important channels for people to publish, obtain, and disseminate event information. The sorting and research of these events will help people understand the law of event development and guide production and life. It also has a wide range of needs and applications in fields such as news recommendation and public opinion analysis. [0003] At present, the event map is still a relatively new concept, which records the correlation and causal relationship between events. In the event map, each event corresponds to a diff...

Problems solved by technology

[0004] Because the event map is different from the entity knowledge map with the concept-practical example as the core, it is difficult to control the effect of event extraction. It is difficult for the event extraction system to distinguish which events are important and which events are not important. At the same time, events are not accurately checked. Makes the quality of the constructed event map lower
