Makoto Yamakawa presented his research findings at the ACM Conference on Hypertext and Social Media. This year, the conference was held in Rome.
The current route from Japan to Europe looks like this because we can’t fly over Russia.
This is one of the entrances to the conference venue. (Although we used a different entrance for this conference.) It is located right next to Piazza di Spagna and is sometimes referred to as the “House of Monsters” (Palazzo Zuccari) in some guidebooks.
The photo below captures his presentation. Unfortunately, it was difficult to adjust the brightness properly for both his face and the screen at the same time.
The presentation was on his undergraduate thesis research, which explored ranking social media users based on their information-gathering apabilities on social media.
Katz centrality is a well-known measure that represents the strength of a node’s connections to other nodes in a graph. In this study, Katz centrality was extended to account for the differences among users in terms of the value of the information they post and the probability of reposting and forwarding received information.
These days, you can find Japanese food almost everywhere, and supermarkets in Rome were no exception. I spotted a variety of Japanese products there.
I feel like I’ve heard before that the snacks in this photo are sold under this name in certain countries.
The photo below shows a “No Pedestrians” sign that I haven’t seen in Japan (in Japan, isn’t it usually a square sign with a person wearing a hat?).
And this photo shows a bidet, which is commonly found in hotels in Italy.
Thank you for reading until the end.
