Hi there,
This is a note that I just found the correct link for the dataset SIN (which was originally https://www.ntu.edu.sg/home/gaocong/data/poidata.zip). The reason to the invalid url issue is that NTU changed the domain name of each staff member homepage to personal.ntu.edu.sg. However, the directory structure has not been changed. So you can download the SIN dataset from https://personal.ntu.edu.sg/gaocong/data/poidata.zip.
You can close this issue once you update the README.md.
