Problems solved by technology

[0002] In order to enable efficient and fast data retrieval, city data is classified according to the characteristics of high storage cost and low efficiency of information retrieval.
A large amount of data in the city needs to be stored, processed, queried and analyzed before it can be fully applied to various applications. The traditional storage system only collects and stores the data simply, but there is no effective classification research for this information.

Abstract

The invention discloses a city data classification method and system. The method comprises the steps of obtaining city data; weighting the city data to obtain weighted city data; obtaining a clustering centroid by using a particle swarm optimization algorithm according to the weighted city data; and clustering the city data according to the clustering centroid to obtain category groups. The city data retrieval efficiency and city data classification accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of urban data analysis, in particular to a method and system for classifying urban data. Background technique [0002] In order to enable efficient and fast data retrieval, city data is classified according to the characteristics of high storage cost and low efficiency of information retrieval. A large amount of data in the city needs to be stored, processed, queried and analyzed before it can be fully applied to various applications. The traditional storage system only collects and stores the data simply, but lacks effective classification research on this information. In the era of big data, the rapid expansion of urban data scale further highlights the dilemma of traditional methods. How to effectively classify urban data and improve data retrieval efficiency has become an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a method and sy...
