Sano Lab
Machine-translated · View original
A lab that uses web data such as social media to uncover how society moves.
AboutAbout the lab
Understanding society the way physics does
The Sano Lab analyzes data on the web, such as social media, to study universal patterns in how society moves and the patterns in which information spreads.
The lab works in a field called socioeconophysics, which treats people as a collective and analyzes and models them like particles, using the perspective of statistical mechanics.
Once a week, the whole lab holds a lab seminar to report research progress, and once a week it holds a paper reading session in which members take turns presenting the content of a paper.
Many students analyze data in Python, and besides programming, they also use English and mathematics to read papers.
Key terms
- Socioeconophysics
- A research field that analyzes and models the behavior of human groups using the concepts of physics

ResearchResearch themes
Specializing in socioeconophysics, network science, web science, and computational social science, the lab analyzes information posted on social media to investigate universal patterns in how society moves and patterns in how information spreads. It aims to understand the properties that emerge when people are viewed as a collective.
*Illustrative imageInformation Spreading on Social Media
The lab studies how the way information spreads on social media differs between uncertain information and information that is not.
*Illustrative imageDetecting Public Mood
The lab takes on the question of whether the "atmosphere" of a society, that is, the sentiment of a group as a whole, can be measured quantitatively from data.
*Illustrative imageBurstiness of Human Behavior
Focusing on the burstiness of behavior, the lab investigates whether there are general properties shared by many kinds of human behavior.
*Illustrative imageAcademic Networks
The lab analyzes networks of researchers connected through co-authorship, citations, and acknowledgments, and explores whether there are structures that give rise to innovative ideas.
