Repeated alarm recognizing method and system based on search engine

Abstract

The invention relates to a repeated alarm recognizing method and system based on a search engine. The method includes the following steps of S1, establishing a GIS address base; S2, setting an event factor weight value and a repeated alarm threshold; S3, matching the most similar event address map coordinates in the GIS address based on the basis of the search engine, assigning the address base map coordinates with the highest matching degree to current event address map coordinates; S4, determining the event address coverage radius r, and calculating alarm information in the coverage radius range within a time duration delta t according to the event address map coordinates; S5, calculating the matching degree, the comparison matching degree and the threshold for event factors of current alarm information and event factors of the inquiry result through the search engine and the word segmentation technology on the basis of the inquiry result in the step S4, prompting that the current alarm is likely to be a repeated alarm if the matching degree of the alarm is higher than the threshold, and conducting comparison display on the corresponding alarm information. The repeated alarm can be effectively recognized, the recognizing accuracy is high, and the alarm receive-disposal efficiency can be improved.

Description

technical field [0001] The invention relates to the fields of public security and medical alarm reception, and more specifically relates to a method and system for identifying repeated alarms based on a search engine. Background technique [0002] Existing methods for identifying duplicate information mainly perform word segmentation on single-element text to calculate the matching degree, but do not calculate the comprehensive matching degree of information for multi-element word segmentation matching, resulting in a low matching degree. Moreover, the existing methods for identifying repeated information do not involve time and space matching processing. For the fields of public security and medical alarm reception, time and space are very important elements, and the matching processing of time and space can greatly improve the accuracy of repeated information identification. [0003] In the field of public security and medical alarm reception, there are currently few tool...

AI Technical Summary

Problems solved by technology

[0003] In the field of public security and medical alarm reception, there are currently few tools that can provide police officers with effective identification of repeated alarms. Identifying repeated alarms depends more on people's experience and luck. 1. There is a waste of human resources in all aspects of police handling when dealing with repeated police situations
