AboutAbout the lab
Making it easy to store and share information.
The Sakaguchi Lab studies anti-spam techniques, technologies for using the next-generation Internet, and systems that support the accumulation and sharing of information.
There are more and more ways to publish and obtain information on the Internet, but the lab is motivated by the concern that these means are not yet being fully used.
For this reason, the lab aims to develop technologies that let people store and share information with ease.
In the graduate school's faculty introduction, the listed research themes are development support for Linked Data, foundational technologies and applications of crowdsourcing, and the technical infrastructure for sharing and transmitting information.
Key terms

- An approach to publishing data on the web by connecting pieces of data to one another through links, which makes it easier to combine and use the data
- Crowdsourcing
