Typhoon event information aggregation method

Abstract

The invention relates to a typhoon event information aggregation method, which mainly comprises the following steps of: 1, acquiring a message text related to a typhoon event in social media, extracting typhoon event information from the message text, and converting the typhoon event information into a structured information tuple form; 2, performing object information aggregation based on multi-feature similarity; 3, performing state information aggregation based on spatial and temporal features; and 4, performing state-based process information aggregation: screening space-time node information meeting time and position range requirements from the object information aggregation results, performing state information aggregation on the space-time nodes respectively, and sorting a pluralityof state information aggregation results to form process information aggregation results reflecting dynamic characteristics. According to the typhoon event information aggregation method, the typhoonevent information with scattered sources in the social media is screened, organized and integrated, and an ordered information basis is provided for the development stage and situation of the typhoonevent detection process.

Description

technical field [0001] The invention belongs to the field of big data mining, and in particular relates to a typhoon event information aggregation method. Background technique [0002] Typhoons can have very serious destructive effects on natural ecology, social economy, and even human sustainable development. Timely acquisition of relevant information on the evolution of typhoon events has become an important basis and reference for disaster emergency response. In the current big data environment, social media has shown great application potential in disaster management with its efficient update frequency, multi-source communication channels, and extensive participation, and has gradually developed into a new way to obtain typhoon event information. However, due to the short text characteristics of social media itself, there are also characteristics such as high information fragmentation, complex and diverse forms of expression, and diverse information granularity. The mes...
