Description

This part of the work aims to analyze the composition of the user on the social media, who are concerned about global warming and climate change.As more public voices can be heard on social media, this section we try to explore the public's understanding of issues we queried. We have chosen two platforms:Twitter and Weibo and for each platform we collected 600 posts and their users information.

On the left part of chart first we did a qualitative analysis, the user is divided into public and organizations with the cluster dendrogram. On the right part of the chart we did a quantitative analysis of the user, and we use a bar chart to show the number of people who are concerned about both issues. At the end of the chart you will get the total number of public and organizations. The second chart is intended to show the difference between the users and the difference between Weibo and Twitter.

According to the chart we can get some interesting results first the proportion and the type of Organization Weibo is much more than Twitter, second there are more ordinary people speak in Weibo, and more public figures speak in Twitter. Finally, only the government agencies speak in the Weibo, but in the Twitter we can only find the politicians’s tweets.

Protocol

In the beginning we used two tools to collect data，the Gooseeker for weibo and the TwitterR for twitter.when the data collection is complete, we use regular expressions to sort the data into user information and text information, and then we import that two parts of information into the excel to filter and refine, and finally we combine raw and illustrator to represent the data.

Download data

This part of the work is mainly qualitative analysis of the user, we use different tools to collect data, there are many tools available for twitter. These tools can give clear and complete information including user names, hashtag and content of tweet. but for weibo we can only find the visual tools and we collect the data manually. For twitter there are more individual users, we see more opinion from the public, but at the same time the public opinion is more messy, in weibo there are more of the official views and the official views more unified.
