Example Embodiment

[0059] Examples: The following examples illustrate the present invention in detail.

[0060] Background introduction: Due to the need for optimization and adjustment of the public transportation system, Nanjing needs to collect opinions or suggestions from the masses on Nanjing Public Transport, as an important reference for the optimization and adjustment of public transportation routes. At the same time, Nanjing needs to collect and sort out recent media related to Nanjing Public Transport The report is used as a reference. If conventional survey methods are used, more human, material, and financial resources will be required. And in this embodiment, taking Sina Weibo as an example, the specific steps and results are as follows:

[0061] Step 1. According to actual needs, select "Nanjing" and "Bus" as Weibo keywords. Through the API platform of Sina Weibo, all Weibo including "Nanjing" and "Bus" can be collected. In this example, only microblogs in a certain period of time in ...

Abstract

The invention discloses a traffic data obtaining method based on microblogs. The method comprises the steps of collecting the public traffic related microblogs, conducting word segmentation processing on each microblog, obtaining term composition of each microblog, generating a space vector of each microblog on the basis of the word segmentation result, conducting support vector machine training and classification analysis on the space vector of each microblog, finally achieving automatic classification discrimination of the microblogs through a computer, and extracting valuable information. According to the traffic data obtaining method, the traffic related data are automatically, rapidly and concurrently obtained from a large number of numerous and disordered data of the microblogs, meanwhile, features in the data are visually shown, and the data are accurately screened and classified. According to the traffic data obtaining method, a large number of classification traffic related data can be conveniently obtained with the low input, and the traffic data obtaining method is of great practical significance.

Description

technical field [0001] The invention relates to a data collection and processing method, in particular to a microblog-based traffic data acquisition method. Background technique [0002] With the rapid development of our country's social economy, a series of problems represented by traffic congestion, traffic environmental pollution and traffic accidents have emerged in major cities. The root cause is the imbalance between traffic supply and demand. Compared with pure natural sciences such as mathematics and physics, which rely on formulas and experiments, transportation science is more of a system engineering science. Therefore, for the solution of such problems, we cannot fully rely on the iteration of theoretical formulas and simulation experiments. When searching for solutions to traffic problems, carrying out traffic design, new construction, reconstruction and expansion of traffic facilities, etc., it must be based on a reasonable and effective grasp of actual traffic...
