Yesterday, we have a meeting about the paper of null values, and some decisions are made.

1. we decide to reconstruct the draft and submit the modified version CleanDB06. The deadline is Jun 2nd, and the date of notification is July 4th. It's probably for us to receive some response from CleanDB, and improve our paper before the deadline of ICDE on July 12. 

2. Dr.Candan starts working on the current draft to condense it in a short paper as the first version. 

3. I am going to make some screenshots about the potential software for the null valued document processing.
