Sano, Yukie;Takayasu, Hideki;Havlin, Shlomo;Takayasu, Misako
PLoS ONE   14(3) e0213843   Mar 2019   [Refereed]
Collective emotion has been traditionally evaluated by questionnaire survey on a limited number of people. Recently, big data of written texts on the Internet has been available for analyzing collective emotion for very large scales. Although shor...

Nonlinear Theory and Its Applications, IEICE   9(3) 382-390   Jul 2018   [Refereed]
<p>In recent times, research on extracting collective emotion from social media has been actively pursued. When constructing collective emotions from social media, a bag-of-words, which is made of an aggregation of related words' frequencies, is o...

Physical Review E   98(1) 012312   Jul 2018   [Refereed]
Correlation matrices are a major type of multivariate data. To examine properties of a given correlation matrix, a common practice is to compare the same quantity between the original correlation matrix and reference correlation matrices, such as ...
Fake news propagate differently from real news even at early stages of spreading

arXiv:1803.03443      Mar 2018
Physical Review E   94(5) 052317   Nov 2016   [Refereed]
To elucidate the nontrivial empirical statistical properties of fluctuations of a typical nonsteady time series representing the appearance of words in blogs, we investigated approximately 3×109 Japanese blog articles over a period of six years an...

Fluctuation scaling in online social media”, Proceedings of 2015 International Conference on Noise and Fluctuations (ICNF)      Jun 2015
To examine number fluctuations in online social media, we focus on the daily appearances of adjectives, adnominal particles, and conjunctions in a Japanese blog space. We show that a non-trivial fluctuation scaling law exists between the standard ...
PLOS ONE   10(4) e0121443   Apr 2015   [Refereed]
We focus on Internet rumors and present an empirical analysis and simulation results of their diffusion and convergence during emergencies. In particular, we study one rumor that appeared in the immediate aftermath of the Great East Japan Earthqua...
