Due to the COVID-19 global pandemic, many events ha to be forced to conduct as virtual online events. However, online conferences are quite new to almost all participants. Therefore, there is still some room to support not only the participants but also the event organizers. This spring, I developed an OSS system called OLiVES (this stands for On-Line Virtual Event Support system), which was more than just an event scheduler, and it has a kind of recommendation engine to offer the efficient information for the participants. The recommendation helps participants in the online event to choose proper presentations that can be matched with their preferences. I would like to introduce you to the overview of OLiVES, the structure of the system, some results from the real operation this spring. My presentation could be useful if the next COSCUP will be held on-line. Also, it could be useful for anyone considering to organize some online events. In addition, I also developed a simple SNS-like communication system called DiaLogBook, which was useful for tele-lecture, online simultaneous classes. I will introduce it in this talk, it would offer useful information for anyone who is engaged in online education.
