Presentation of the research by Masafumi Iwanaga at IEEE BigData 2024
This presentation was about a method of suggesting the topic to SNS users. However, it is not about topic recommendations to the orginary users, but rather about suggesting the next topic for users who act as influencers. For example, a user who has gained a steady number of followers through game streaming can’t just keep playing the same game forever to maintain their audience. They eventually need to shift to…

Research Presentation by Yixin Zhang at ACM Multimedia Asia 2024
Yixin Zhang of our research group gave presentation at ACM Multimedia Asia 2024. This presentation focused on ingredient recognition from images in recipe data that describe cooking procedures. Recipe data consists of a sequence of descriptions for each cooking step. As a result, the image for each step often contains ingredients that also appeared in previous steps. However, because recipes can include branching and merging steps, ingredients do not always…

Presentation by Hirotaka Nagashima at WWW Conference 2024
Hirotaka Nagashima from our group gave a presentation at The Web Conference 2024. The presentation was about identification of descriptions that indicate the “expiration time of information value.” For example, suppose a text includes phrases like those below. “Please submit application by 17:00 tomorrow. “Live streaming starting 19:00 tonight!” The informational value of such a text must largely decrease after the time described in these descriptions. Therefore, if we can…
