Leiden Weibo Corpus - Open access
We believe it's important for researchers to make their research data available freely to others. That's why most of the data collected for this project is available below. These files are under the CC BY-NC-SA 3.0 license; see the legal details.

These CSV files are in ZIP archives. You can uncompress them by using a utility like WinZip or Linux unzip. All files were last updated on March 20th, 2012.

All files are CSV files that were exported using the mysqldump utility, encoded in UTF8. Fields are escaped by backslashes, enclosed by double quotes and separated by commas. Rows are separated by a line break (\n). Empty fields are set to NULL (\N), not to an empty string ("").
