A distributed system architecture for pedestrian flock detection with participatory sensing
Teemu , Leppanen JoseAlvarezLacasia Masayuki , Iwai Kaoru , Sezaki Yoshito , Tobe Jukka , Riekki
2013-MBL-65(40) 1 - 7   Mar 2013
We present distributed system architecture for smartphone-based participatory sensing applications, where the computational load is distributed between the participating devices. The system allows using of static data to reduce the computational l...
What Does Chirping Tell Us? Summarizing People's Opinion on Ongoing Events Using Tweets
Khan Muhammad Asif Hossain・Guangwen Liu・Masayuki Iwai・Sezaki kaoru
pp.107-112   Mar 2013
We propose a set of algorithms for filtering out tweets relevant to any ongoing event, which can serve as a real-time summary about people’s opinion regarding the event. Evaluation conducted on a real-world dataset shows that the proposed model co...
