Abstract (in Japanese) (See Japanese page) 
(in English) The dynamics of network services' growth and decline are similar to infectious disease.
So, it is expected that we can explain the growth and decline of a network service by using epidemiological models.
The irSIR model is proposed as one of promising model for describing epidemiological transition of network services.
To study the validity of applying the irSIR model, this paper focuses on SNSs transition occurred in Japan and online game services transition not did, and investigates the transition between SNSs and online games by analyzing the sequence of the number of each word searches.
By comparing the well-known SIR model and irSIR model, we show that irSIR model gives better fitting to only the real data of SNSs.
This result indicates that the transition of SNS is accelerated by invitation of new service users.
