Research Presentation by Mizuki Hisatomi at ACM UIST 2025
Her research concerns a method for automatically grouping web browser tabs that are related to the same task, in order to solve the problem of finding the desired tab becoming difficult when many tabs (e.g., several dozens) are open simultaneously in a web browser. Existing research includes methods such as creating a classifier using machine learning that, given a sequence of tab transitions, determines where a transition is to another…

Presentation of the research by Masafumi Iwanaga at ACM Hypertext 2025
We presented our research findings at the ACM Conference on Hypertext and Social Media 2025. This research focuses on investigating whether friend recommendation in social media accelerates the formation of echo chambers. In a simulation starting from a subgraph of the actual X (formerly Twitter) follow graph, we compared four types of friend recommendation methods: Friend recommendation based on the similarity of followees’ topics (CM) Friend recommendation based on Most-Common-Neighbors…

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 of the research by Mamoru Yamakawa at ACM HT 2023
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…

Eisaku Yoshikawa of our group gave presentation at ACM International Conference on Multimedia Retrieval (ICMR) 2024. The presentation focused on “exclusion queries” in image retrieval. In this context, exclusion queries refers to the queries to search for images related to “A” but not to “B,” similar to how Web search engines interpret queries like “A -B.” In recent years, automatic image captioning (automatic generation of text descriptions of images) has…

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…

Eisaku Yoshikawa was awarded the best interactive presentation award at DEIM 2023
Eisaku Yoshikawa received the Best Interactive Award at the 15th Forum on Data Engineering and Information Management (DEIM 2023) for his presentation. This year, three presentations were selected for the top award out of 342 poster presentations. His research focuses on exclusion queries for image searches. Exclusion queries are widely used in general web search engines. For example, if someone wants to search for information about the animal “jaguar,” but…

Research presentation by students at DEIM 2023
Our lab members present their research every year at the Forum on Data Engineering and Information Management (DEIM), a domestic forum held in early March. For the past three years, DEIM was held online due to COVID-19. However, DEIM 2023 marked the first partial in-person event in four years. Six students of our group gave presentations this year: Erina Yamakawa: “Similarity Measurement for Each Component Considering the Meaning of Triplets”…
