Research Topic: Temporal Aspects in User Modeling.
Supervisor: Prof. Tsvi Kuflik.
The main idea of my research is to standardize temporal aspects in user modeling that can be used to characterize user behavior, especially in Recommender Systems, provide generic guidelines and point the gaps for future research. The widespread use of temporal aspects in recommender systems indicates their importance, as it showed to be highly effective in various domains related to user modeling. Still the ongoing research, spread over several decades, provided multiple ad-hoc solutions, but no common understanding of the issue. There is no standardization and there is often little commonality in considering temporal aspects in different applications. This may ultimately lead to the problem that application developers define ad-hoc solutions for their problems at hand, sometimes missing or neglecting aspects that proved to be effective in similar cases.
