Keynote title: Cross-domain Approaches for User Activity Prediction in On-line and Real Worlds
In smart cities, varieties of services in both on-line and off-line (real) worlds support people’s daily life.
To provide effective personalized services, cross-domain approaches for predicting user activities are promising, since data obtained from different service domains cover a wide range of user activities.
In this talk, we will present our recent work on cross-domain user activity prediction.
In particular, we focus on two domains, Web advertisement and E-commerce domains, and present some user purchase prediction models, which recommend products in the E-commerce domain to users in the Web advertisement domain.
We also show the results of our preliminary analysis to investigate the impact of COVID-19 on user activities in both on-line and off-line worlds.
Finally, we will talk about our future directions.
