Sina Weibo (新浪微博), commonly referred to as "Chinese Twitter", is a micro-blogging site. This Weibo dataset was used in Analysis of misinformation during the COVID-19 outbreak in China: cultural, social and political entanglements. You can access the ppaer through this link. The data was crawled on the Weibo platform from December 7, 2019, to April 4, 2020.

The data is crawled in two phases, covering a total of 4,047,389 Weibo posts. The first crawler ran on February 26, 2020, and collected 3.3 million Weibo posts from January 18, 2020, to February 26, 2020. The second crawler ran on April 4, crawling from December 7, 2020, to April 4, 2020, to complement the original dataset. The temporal distribution of the Weibo data is shown in Figure 1.

The Weibo data is obtained by a python crawler. The crawler automatically uses Weibo's advanced search function for keyword indexing.

The keywords we used included:

• COVID-19
• novel coronavirus(新型冠状病毒)
• corona(新冠)
• epidemics(疫情)
• novel pneumonia(新型肺炎)
• pneumonia in Wuhan(武汉+肺炎)

The crawler program automatically entered one of the keywords into the query box and set the query time range to be a specific hour. As illustrated in Figure 2, the crawler sets the time range from January 18, 2020, 00:00:00 to January 18, 2020, 01:00:00.

For each query, the time range increased by one hour, and each query searched all the new posts within an hour. Each query returned a maximum of 50 pages, each contained around 20 posts. If the number posts exceed the page limits, we cannot fully collect the information due to the limitations of the search function.
