Embodiment Construction

[0050] 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 conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] Such as figure 1 As shown, the method for simulating air quality using microblog keywords and location information in the embodiment of the present invention includes the following steps:

[0052] S1. Obtain microblog data, including microblog data with air quality keywords and microblog data without air quality keywords, and preprocess it;

[0053] S2. With a certain monitoring station as the center, establish buffer zones of different sizes, standardize the number of microblogs with air quality keywords in each buffer zone, and calculate the relationship between the standardized number of...

Abstract

The invention discloses a method and a system for simulating air quality by microblog keywords and position information. The method includes the steps of S1, acquiring microblog data and preprocessing the microblog data; S2, establishing different sizes of buffer zones, standardizing a microblog number in every buffer zone, computing a correlation coefficient between every standardized number and a monthly average AQI (air quality index) of monitoring stations, and comparing the correlation coefficients of the buffer zones different in radius so as to obtain the sizes of the buffer zones maximum in correlativity; S3, performing grid division, extracting relative microblog numbers and fitting a function relation between the relative microblog numbers and the monthly average AQI; S4, acquiringsimulation AQIs of all grids through the fitting function and improved inverse distance weighted interpolations; S5, subjecting all the grids to Kriging interpolation according to the simulation AQIs of all the grids so as to obtain air quality trend-surface model. The method is capable of reflecting air quality distribution conditions at different positions of a city and discovering key factors affecting the air quality.

Description

technical field [0001] The invention relates to the field of social media data applications, in particular to a method and system for simulating air quality by using microblog keywords and location information. Background technique [0002] Human society is entering the era of "big data", and the vigorous development of the Internet and the information industry has attracted widespread attention. The rise of big data brings new opportunities for us to understand the social environment, and can effectively capture various social characteristics. Wikipedia's definition of social media is: Social media is a computer-mediated tool that allows people to create, share or exchange information, ideas, pictures, and videos in virtual communities or networks. Social media is defined as "a set of Internet-based applications built on the ideas and technologies of Web 2.0 and allowing the creation and exchange of user-generated content". With the ever-increasing amount of data generate...
