Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific implementation cases and with reference to the accompanying drawings.

[0061] see figure 1 , considering the special text, geographic location and other information contained in the microblog, the present invention proposes a method for exploring urban functional areas using the microblog data containing location information. The invention fully considers the time and space characteristics of urban residents' activities, and extracts the time pattern and spatial distribution pattern of microblogs on the basis of grid division and clustering of the research area, and combines POI data and microblogs The text effectively gets functional area information for various areas.

[0062] First introduce the theoretical basis:

[0063] POI is the abbreviation of "Point of Interest", which c...

Abstract

Provided is an urban functional domain detection method by means of microblog position information. The method comprises the steps that a survey region is selected, grid division and division of microblog time periods are conducted on the survey region, functional domains where various regions belong to are predicted according to microblog data for multiple days; the microblog data for multiple days are separated according to working days and weekends, and clustering regions and corresponding functional domain research results are updated; functional domain verification is conducted according to POI data in all the clustering regions, functional domain verification is conducted according to microblog text data in microblog time mode peak points of all the clustering regions, and functional domain verification is conducted according to subject terms of microblogs in all the clustering regions. According to the urban functional domain detection method by means of the microblog position information, the urban functional domains are explored by means of the microblogs containing the position information, data acquisition is convenient, the verification results are effective and rapid, the cost is reduced, the method can be used for detecting change tendency of the urban functional domains, and the method can help urbanists and decision makers to conduct scheming on public service, public resources and the like.

Description

technical field [0001] The present invention relates to the field of social media data application, and more specifically, to a method and system for exploring urban functional areas using microblogs.
