I had the chance to collaborate with Prof. Jöran Beel and Prof. Akiko Aizawa at NII (National Institute of Informatics) in Tokyo, researching the number of recommendation that should be displayed – inviting clicks, but not overwhelming the user. After my stay in Tokyo, I traveled to Shanghai and Hong Kong to give presentations about my work at the group of Prof. Yang Chen at Fudan University in Shanghai, and Prof. Pan Hui at HKUST (Hong Kong University of Science and Technology). Software Campus reported about my trip here.
