Context

From the beginning of 2020 to April 8th (the day Wuhan reopened), this dataset summarizes the social media hotspots and what people focused in the mainland of China, as well as the epidemic development trend during this period. The dataset containing four .csv files covers most social media platforms in the mainland: Sina Weibo, TikTok, Toutiao and Douban.

Sina Weibo

a platform based on fostering user relationships to share, disseminate and receive information. Through either the website or the mobile app, users can upload pictures and videos publicly for instant sharing, with other users being able to comment with text, pictures and videos, or use a multimedia instant messaging service. The company initially invited a large number of celebrities to join the platform at the beginning, and has since invited many media personalities, government departments, businesses and non-governmental organizations to open accounts as well for the purpose of publishing and communicating information. To avoid the impersonation of celebrities, Sina Weibo uses verification symbols; celebrity accounts have an orange letter "V" and organizations' accounts have a blue letter "V". Sina Weibo has more than 500 million registered users;[12] out of these, 313 million are monthly active users, 85% use the Weibo mobile app, 70% are college-aged, 50.10% are male and 49.90% are female. There are over 100 million messages posted by users each day. With 90 million followers, actress Xie Na holds the record for the most followers on the platform. Despite fierce competition among Chinese social media platforms, Sina Weibo has proven to be the most popular; part of this success may be attributable to the wider use of mobile technologies in China.[https://en.wikipedia.org/wiki/Sina_Weibo]

Content

Weibo realTimeHotSearchList can be regarded as a platform for gathering celebrity gossip, social life and major news. In this document, I collect the top 50 topics of the hot search list every 12 hours during the day, so there are 100 hot topics each day. These topics are converted into English by Google translation, although the translation effect is not ideal due to sentence segmentation and language background deviation. In this document, I created a new column ['Coron-Related ( 1 yes, 0 not ) '] to mark topics related to the new crown, if relevant, it is marked as 1, if not then marked empty or 0. The google translation is extremely inaccurate (so maybe google the Chinese title to confirm is the best bet...
